The Eaton® 9PXM uninterruptible power system (UPS) is a modular UPS that contains two battery modules
per slot (two-battery slot) and power control modules (referred to as power modules). These modules plug into
a rack cabinet structure containing additional control, communication and display functions that enable
integrated control of all power modules. The UPS is housed in a single cabinet with either eight or twelve slots
which may be either floor or rack-mounted. Optional extra battery capacity is housed in extended battery
module (EBM) cabinets.
The twelve-slot UPS cabinet can accommodate a maximum of six power modules and two battery modules per
slot in the remaining six slots. However, if a customer chooses to only have one power module they can install
two battery modules per slot in the remaining eleven slots. The eight-slot cabinet can accommodate the same
configuration with two less total units each. Both UPS cabinet models allow their output to be limited such that
an excess number of power modules allow the failure of one or more modules without causing the UPS to lose
any functionality. Optional super charger modules can be installed in the power module slots.
The power modules can be removed and replaced (easily replaceable) without powering the UPS down if the
UPS has sufficient redundant capacity. Battery modules (2 battery modules per slot) may also be easily
replaced for maintenance. Power control circuitry in the cabinet senses problems in power modules, and
automatically transfers control and load to the remaining power modules. Battery modules and Power modules
are accessed through removable front panels.
All power modules share the load requirements equally. For example, three power modules are capable of
supplying a total of 12 kVA. If a load requires only 6 kVA, each power module supplies 2 kVA to the output.
If one power module is removed or for some reason fails, each of the two remaining power modules would
supply half of the load, or 3 kVA. In other words, redundancy exists when the load can be supplied by less than
all of the installed power modules.
To permit UPS removal from the power path while maintaining power to the loads, an external bypass switch
is required. This switch is optional but recommended for system serviceability.

The BPM has three operating positions (see Table 3 ). Consider both the operating state of the UPS and the
BPM when protecting your critical loads.
Failure to understand the correct bypass sequence and position may cause the critical load to be dropped.
Damage to the power modules or the Bypass switch can occur.
• If the UPS remains in Bypass Mode and incoming AC power is lost, the load is automatically dropped. The
UPS must be in Normal Mode to provide battery backup power.
• In the UPS or LINE position, AC input power is still connected to the input terminals inside the UPS.
• If the UPS is in the standby mode and the bypass switch is in the LINE or UPS positions pressing
the red bypass switch interlock button will energize the UPS output.
• Do not attempt to push the red interlock button or attempt to move the bypass switch handle if the
UPS is operating on battery power.
• If you have any questions or problems with the bypass operation, call the Help Desk (see , “
11.2 Service and Support ” ).
The BPM consists of a load position handle and a red button (see Figure 26 ).
Figure 26. Bypass Switch Positions

Interlock Button (red)
Bypass switch
handle
The red button:
• Sends an electrical signal to the UPS to switch to the Bypass Mode (if it is not already operating in that
mode ).
• Operates a mechanical interlock, to prevent the switch from being turned without first signaling the UPS.
You must press the red button before you can turn the load position handle.
When the red button is pressed, the UPS front panel displays “Bypass Mode.” To move the MBP switch
handle from one position to another, the red button must be pressed WHILE the handle is being rotated.
Otherwise, the switch will be damaged.
The bypass switch has three positions as described in Table 3 .
Bypass Overview
4–20kVA Users Guide P-164000669 4–20kVA Users Guide P-164000669—Rev 10 29
NOTE In the UPS or LINE position, AC input power is still connected to the input terminals
inside the UPS.
Table 3. Bypass Switch Positions
Switch Position Description
LINE When the switch is in the LINE position, utility power is directly connected to the
critical load and the output of the UPS is disconnected. In this state the UPS remains
powered, which is often beneficial for troubleshooting, obtaining logs, or updating
firmware.
UPS The normal operating state of the system occurs when the BPM switch is in the UPS
position. Utility power is fed to the bypass, where power is then fed to the UPS. The
UPS provides critical battery backup and power conditioning and power is then fed
back to the bypass switch and then the critical load.
Service Like the LINE position, the SERVICE position connects the load directly to AC input
power and disconnects UPS output; however, because SERVICE also disconnects AC
input from the UPS, this is the appropriate position for UPS maintenance or repair. In
the SERVICE position, the UPS can be completely removed from the system.

• If you have any questions or problems with the bypass operation, call the Help Desk (see , “
11.2 Service and Support ” ).
To turn the BPM to SERVICE:
1. Press and hold the red button and turn the switch to LINE (see Figure 27 ).
NOTE Pressing the red button sends the UPS into Bypass Mode. This allows the UPS output
to synchronize with utility for safe, uninterrupted transfer.
The UPS is now in LINE mode. The critical load is fed directly from utility and the UPS remains energized
from utility power. The UPS may be left in this mode while trying to troubleshoot, gather alarms from the
UPS, or perform other preventative maintenance activities.

• This UPS contains its own energy source (batteries). The output receptacles may carry hazardous voltage
even when the UPS is not connected to an AC supply. When AC input voltage is present, the Eaton 9PXM
system can provide output voltage even though its batteries are disconnected. To confirm that there is no
UPS output voltage, always disconnect all of the AC input sources and unplug all two battery modules per
slot of internal batteries; if the UPS has one or more separate battery cabinets (EBMs), open (push in) the
DC emergency disconnect switch button on each battery cabinet or unplug two battery modules in each
slot of the battery cabinet.
• To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity controlled, indoor
environment, free of conductive contaminants. Ambient temperature must not exceed 40°C (104°F). Do
not operate near water or excessive humidity (95% maximum).
• For optimum battery life, ambient temperature should not exceed 25°C (77°F). Battery life is substantially
reduced if ambient temperature is higher.
• Do NOT attempt to move the cabinet with the power or battery modules installed.
The UPS power modules (UPMs) are installed in the left hand slots of the UPS facing the user. Battery modules
are installed in the left or right hand slots (it takes two battery modules per slot to equal one battery string).
Removal of the power modules and battery modules is the reverse of these procedures.
Install the UPMs into the Eaton 9PXM cabinet: as follows:
1. Remove the front cover(s) of the cabinet. The covers have magnetic latches on the left and right sides that
hold them in place.
NOTE 1 Place battery modules beside all power modules in the UPS cabinet. Two battery
modules installed on top of each other are required for each battery slot and can be
removed separately.
NOTE 2 If you are installing a super charger module in the UPS, the super charger can be
installed in any of the left side slots. In the EBM, the super charger can only be installed
in the lower left side slot.
NOTE 3 The installation procedures of the optional battery cabinet (EBM) battery, and super
charger modules are identical to the UPS units.
NOTE 4 Battery modules are shipped fully charged. It is recommended to charge the batteries
for 48 hrs. after installation to ensure full power. If AC power fails before full battery
charge, backup will be available but for a reduced duration.
2. Insert the power modules into the left hand slots of the cabinet. Push each module firmly until it contacts
the connections in the rear of the slot.
3. Tighten the captive screw
4. To install the battery modules
• Slide the lower battery module fully into the slot until it contacts the connections in the rear of the slot.
• Repeat the procedure with the upper battery module.
• Install the retaining bracket and tighten the captive screw with a Phillips screwdriver.

battery cabinet. Insert the switch key supplied with the cabinet into the button and turn clockwise 1/2-turn.
Pull the button out to close the switch. Turn the key back counter-clockwise, and remove the key.
5. The UPS front panel display automatically turns on whenever input power is present and at least one
power module is installed. Set up the initial operating parameters through the front panel display (see “
6.5 Initial Startup Parameters ” ).
6. Use an AC voltmeter to measure voltages on the terminal block inside the bypass switch cabinet. See
Figure 19 , which shows the terminal numbering for input and output UPS connections.
7. Record your measurements in the following chart. The voltages in the first column should be nearly equal
to the voltages in the second column. If the values differ by more than a few volts, check the terminal
block connections and correct any wiring problems.
AC Line input Measurement AC from UPS Output Measurement
L1 to L2 (11 to 12*) 7 to 8*
N to L1 (10 to 11*) 6 to 7*
N to L2 (10 to 12*) 6 to 8*
* For some installations, there is no connection at terminals 6, 8, 10, or 12.
8. Determine what type of bypass switch you are using:
If the bypass switch is a Break-Before-Make type, skip this step and proceed to Step 13.
If the bypass switch is a Make-Before-Break type, verify that the AC voltages from the UPS and the AC line
input are in phase. Measure the voltage between the following points on the terminal block and record in
the spaces below. These measurements must be no more than 20 Vac; if they are, call your service
representative.
Terminal 7 to 11
Terminal 8 to 12
9. Measure the AC voltage between the following points on the terminal block and record in the space
below. This reading must be no more than 1 Vac; if it is, call your service representative.
Terminal 6 to 10
10. Switch the bypass switch to LINE. Measure the voltage to the protected equipment (at the load
distribution panel) and verify that it is correct.
11. Switch the bypass switch to UPS and verify the voltage to the protected equipment is still correct.
12. Reinstall the bypass switch front cover and UPS front covers using the original screws.
13. If the UPS will not be operated immediately, switch the bypass switch to SERVICE and push in the DC
emergency disconnect switch button on the back panel of the external battery cabinet closest to the UPS.
Otherwise, continue to Step 14.

Battery Mode
When the UPS is operating during a power outage, the alarm beeps once every ten seconds and the indicator
illuminates solid. The necessary energy is provided by the battery. When the utility power returns, the UPS
transfers to Online mode operation while the battery recharges.
Low-Battery Warning
If the low battery warning occurs, shutdown all applications on the connected equipment because automatic
UPS shutdown is imminent.
If battery capacity becomes low while on Battery mode:
• The
indicator illuminates solid.
• The audible alarm beeps once every 3 seconds. (This warning is approximate, and the actual time to
shutdown may vary significantly.)
• After the UPS shuts down the UPS automatically restarts when utility power is restored (if Auto Restart is
enabled).
End of Battery Backup Time
• All the LEDs go OFF.
• The audio alarms stops.
77..44..33 LLooww BBaatttteerryy WWaarrnniinngg
During discharge, the low battery alarm is activated if the remaining runtime goes below 3 minutes or less than
the setting capacity threshold (0% by default). This threshold can be modified.
77..44..44 BByyppaassss MMooddee
Bypass Mode
In the event of a UPS overload or internal failure, the UPS transfers your equipment to utility power. Battery
mode is not available and your equipment is not protected; however, the utility power continues to be passively
filtered by the UPS. The
indicator illuminates. Depending on overload conditions, the UPS remains in
Bypass mode for at least 5 seconds and will stay in this mode if three transfers to bypass occur within one
hour.
The UPS transfers to Bypass mode when:
• User or Service activates Bypass mode through the front panel LCD or by using an external bypass switch
(BPM or BPE).
• Overload between 105 and 110% for more than 30 seconds
• Overload above 115% for more than 200 msecs
• Output Short
• Hardware fault
• Over Temperature on heatsinks

Following an outage, the UPS restarts automatically when AC input power returns (unless the auto restart
function has been disabled) and the load is supplied again.
Setting High Efficiency Mode
In High Efficiency mode, the UPS transfers to Online (or Battery) mode in less than 10 ms when utility fails.
Transfers to High Efficiency mode will be active after 5 minutes of Bypass voltage monitoring: if Bypass quality
is not in tolerance, then the UPS will remain in Online mode.
To set the High Efficiency mode:
1. Select Settings, In/Out settings, and High Efficiency mode (see Figure 64 ).
2. Select Enabled and Enter to confirm.
3. The UPS transfers to High Efficiency mode after 5 minutes.
NOTE If the input is not stable after enabling HE Mode, the UPS will monitor the input for 5
minutes but if it is stable to begin with, it will transfer immediately.
77..66 CCoonnffiigguurriinngg BByyppaassss SSeettttiinnggss
The following settings are available for configuring Bypass operation (see Figure 64 ).
Changing the Bypass settings changes UPS behavior and may result in decreased protection.
Bypass Voltage Min Limit
The default disables a transfer to Bypass if the measured bypass voltage level is below the nominal output
voltage -12%. You can configure the setting for another voltage value. This setting can be overruled by the
“Protected Bypass” setting.
Bypass Voltage Max Limit
The default disables a transfer to Bypass if the measured bypass voltage level is above the nominal output
voltage +12%. You can configure the setting for another voltage value. This setting can be overruled by the
“Protected Bypass” setting.
Protected Bypass (Enabled)
Allows a transfer to Bypass only when Bypass is within the following specifications:
• Bypass voltage is between the “Bypass Voltage Low Limit” and “Bypass Voltage High Limit” settings
• Bypass frequency is within 5% of nominal frequency.
Unsynchronized Transfers
When Qualify Bypass is set to “Always” or “Always on Fault” you can select the interruption time when
transferring to bypass, default setting is “Half Cycle” but can be changed to “Full cycle”.

Advanced Battery Management (ABM) extends the life of the battery by shutting off the charger for 28 days
per ABM cycle and therefore reduces grid corrosion in the battery caused by trickle charging over long periods
of time. Disabling ABM means the battery chargers run in constant charge mode and never turn off. The
battery test period is every three ABM cycles.
NOTE It is not recommended to perform a battery discharge test more often than 90 days.
77..77..22 AAuuttoo BBaatttteerryy TTeesstt
The battery test will run only in Rest Mode and if ABM is enabled. The tests frequency can be modified. During
the test, the UPS transfers to Battery mode and discharges the batteries for 25% battery time remaining.
NOTE Battery mode is not displayed and battery low alarm does not activate during a battery
test.
The battery test may be postponed due to bad conditions, or failed if battery is not ok.

Maintenance Bypass: The signal from an external bypass switch, to isolate the Eaton 9PXM system for
maintenance purposes, tells the UPS to go into Internal Bypass mode.
On Generator: The signal allows the UPS to optimize its operation with the generator by transferring the UPS
from High Efficiency mode to Normal (double conversion) mode as long as High Efficiency is set as the default
mode of UPS operation. See IN/Out setting.

Table 7 explains the functions of the pins on the Eaton 9PXM DB-9 communication port. This port is on the
Eaton 9PXM UPS rear panel, as shown in Figure 75 .
Pin Function Description
1
Low Battery Alarm
Pin 1 shifts from RS-232 Low (negative voltage) to RS-232 High (positive
voltage) and remains high whenever the UPS enters a Low Battery alarm
state.
2
RS-232 Transmit Data
Sends outgoing RS-232 communication data at 9600 baud, 8 bits, no
parity, 1 stop bit.
3
RS-232 Receive Data/
RS-232 Shutdown
RS-232 Receive Data Function. Receives incoming RS-232 communication
data at 9600 baud,8 bits, no parity, 1 stop bit.
RS-232 Shutdown Function. If Pin 3 receives an RS-232 Low signal (+Vdc)
for at least 5 seconds, but not more than 7 seconds, during an AC Failure
condition, the UPS output shuts off following a delay of 120 seconds (±5
seconds).
4
Reserved Loopback to Pin 6
5
Common Signal Ground
6 Reserved Loopback to Pin 4
7
No Connection Open Pin
8
AC Fail Signal
(On-Battery)
Pin 8 shifts from RS-232 Low (positive voltage) to RS-232 High (positive
voltage) and remains high for 15 seconds (±1 second) after the UPS
detects an AC Failure condition, assuming the condition still exists after
the 15 seconds.
When the AC Failure condition no longer exists, the signal returns to the
RS-232 Low state (positive voltage).
9
No Connection/
DC Supply Voltage
The UPS is factory-set with Pin 9 disconnected, but can be enabled
through a technician-replaceable jumper inside the UPS. The jumper
setting MUST be changed by a qualified service technician.
When enabled, Pin 9 provides supply voltage for use with external
connectivity devices requiring DC power directly from the UPS DB-9 port
(nominal 12 Vdc/5W; 8V minimum, 24V maximum). Use only Eaton brand
connectivity devices.

This chapter provides maintenance information to help maintain proper UPS operation.
NOTE 1 Observe important safety precautions while performing these checks.
NOTE 2 Eaton recommends that you schedule preventive maintenance checks at least every six
months.
The Eaton 9PXM system is designed to provide years of trouble-free operation. Its internal control system
checks the batteries and inverter periodically to ensure reliable operation.
The Eaton 9PXM UPS and optional external battery cabinets do require some attention to assure continued
reliable service. Follow Eaton's recommended maintenance schedule, which includes:
• Check operating environment for clean, cool, dry conditions.
• Inspect and clean the area around the UPS
• Check operation of fans (power modules).
• Check the batteries.
For more information on preventive maintenance checks, contact your service representative.
99..22 SSttoorraaggee TTeemmppeerraattuurree
Store the Eaton 9PXM battery modules (in the UPS or external battery cabinet) at –20 to +40°C (–4 to +104°F).
Batteries will have a longer shelf life if they are kept below +25°C (+77°F). The Eaton 9PXM UPS or battery
cabinet without batteries may be stored at –40 to +60°C (–40 to +140°F).

Press the red button beside the switch before turning the Eaton MBB bypass switch. This button:
• Sends an electrical signal to the UPS to switch to the internal Bypass mode (if it is not already operating in
that mode ).
• Operates a mechanical interlock, to prevent the switch from being turned without first signaling the UPS.
Failure to understand the correct bypass sequence and position may cause the critical load to be dropped.
Damage to the power modules or the Bypass switch can occur.
• If the UPS remains in Bypass Mode and incoming AC power is lost, the load is automatically dropped. The
UPS must be in Normal Mode to provide battery backup power.
• In the UPS or LINE position, AC input power is still connected to the input terminals inside the UPS.
• If the UPS is in the standby mode and the bypass switch is in the LINE or UPS positions pressing
the red bypass switch interlock button will energize the UPS output.
• Do not attempt to push the red interlock button or attempt to move the bypass switch handle if the
UPS is operating on battery power.
• If you have any questions or problems with the bypass operation, call the Help Desk (see , “
11.2 Service and Support ” ).
See “ 3.6 Bypass Overview ” for additional information.

The Eaton 9PXM hot-swappable feature lets you replace the battery modules without disconnecting the load or
damaging the batteries.
NOTE The Eaton 9PXM UPS will operate with uncharged (or no) batteries, but will have limited
(or no) battery backup capability. The UPS will indicate an alarm with a insufficient
number of batteries present. One battery string (two battery modules) must be installed
adjacent to each power module.
To replace a two-battery slot in pairs:
1. Remove the front cover.
The cover has magnetic latches on the left and right sides that hold it in place.
2. Loosen the captive screw on the retaining bracket and slowly pull the upper battery module out of the
cabinet.
3. Repeat the procedure with the lower battery module.
4. Treat the original and replacement battery modules with care to avoid damaging connectors or internal
circuitry. Label the original batteries with masking tape or some other identifier. Record the serial number
of the replacement modules for your warranty.
5. Insert the replacement battery modules by sliding the lower module carefully into the cabinet. Repeat for
the upper replacement module.
6. Reinstall the retaining bracket and tighten the captive screw.
7. Replace the front cover.

insufficient to supply the required power. If empty slots exist, install replacement
modules before removing original ones.
Use care in removing and installing power modules. To remove a power module:
1. Remove the front cover.
The cover has magnetic latches on the left and right sides that hold it in place.
2. Loosen the captive screws at the sides of the power module and slowly pull the power module out of the
cabinet.
3. Treat the original and replacement power modules with care to avoid damaging connectors or internal
circuitry. Label the original power modules with masking tape or some other identifier. Record the serial
number of the replacement power modules for your warranty.
4. Insert the replacement power module by sliding it carefully into the cabinet.
5. Tighten the captive screws to the UPS cabinet.
6. Replace the front cover.

The Eaton 9PXM is designed for durable, automatic operation and also alert you whenever potential operating
problems may occur. Usually the alarms shown by the control panel do not mean that the output power is
affected. Instead, they are preventive alarms intended to alert the user.
• Events are silent status information that are recorded into the Event log. Example = "AC freq in range".
• Alarms are recorded into the Event log and displayed on the LCD status screen with the logo blinking.
Some alarms may be announced by a beep every 3 seconds. Example = "Battery low".
• Faults are announced by a continuous beep and red LED, recorded into the Fault log and displayed on the
LCD with a specific message box. Example = Out. short circuit.
• Use the following troubleshooting chart to determine the UPS alarm condition.
Typical Alarms and Faults
To check the Event log or Fault log:
1. Press any button on the front panel display to activate the menu options.
2. Press the down arrow button to select Event log or Fault log from the Menu screen.
3. Scroll through the listed events or faults. See 7.8 Retrieving the Event Log and 7.9 Retrieving the Fault Log
.
The following table describes typical conditions.
Table 14. Typicial Alarm Conditions
Possible Cause Conditions
Action
Battery Mode
LED is On
1 beep every 10 seconds
A utility failure has occurred and the UPS
is on Battery mode.
The UPS is powering the equipment with
the battery power. Prepare your
equipment for shutdown.
Battery low
LED is On
1 beep every 3 seconds
The UPS is in Battery mode and the
battery is running low.
This warning is approximate, and the
actual time to shutdown may vary
significantly. Depending on the UPS load
and number of Extended Battery Modules
(EBMs), the "Battery Low" warning may
occur before the batteries reaches low
capacity.
No Battery
LED is On.
Beep continuous.
The batteries are disconnected. Verify that all batteries are properly
connected. If the condition persists,
contact your service representative.
Battery fault
The battery test has failed due to bad or
disconnected batteries, or the battery
minimum voltage is reached in ABM
cycling mode.
Verify that all batteries are properly
connected. Start a new battery test: if
the condition persists, contact your
service representative.

Table 14. Typicial Alarm Conditions (Continued)
LED is On.
Beep continuous.
The UPS does not provide the
expected backup time.
The batteries need charging or service. Apply utility power for 48 hours to charge
the batteries. If the condition persists,
contact your service representative.
Bypass Mode
LED is On.
An overload or a fault has occurred, or a
command has been received and the UPS
is in Bypass mode
Equipment is powered but not protected
by the UPS.
Check for one of the following alarms:
overtemperature, overload or UPS LED is
on failure.
Power Overload
LED is On.
1 beep every 3 seconds.
Power requirements exceed the UPS
capacity (greater than 100% of nominal;
see in Table 8 on page 8 for
specific output overload ranges).
Remove some of the equipment from the
UPS. The UPS continues to operate, but
may switch to Bypass mode or shut down
if the load increases. The alarm resets
when the condition becomes inactive.
UPS Overtemperature
LED is On.
1 beep every 3 seconds.
The UPS internal temperature is too high
or a fan has failed. At the warning level,
the UPS generates the alarm but remains
in the current operating state. If the
temperature rises another 5°C, the UPS
transfers to Bypass mode or shuts down
if Bypass is unusable.
If the UPS transferred to Bypass mode,
the UPS will return to normal operation
when the temperature drops 5°C below
the warning level. If the condition
persists, shut down the UPS.
Clear vents and remove any heat sources.
Allow the UPS to cool. Ensure the airflow
around the UPS is not restricted. Restart
the UPS. If the condition continues to
persist, contact your service
representative.
The UPS does not start. A utility failure has occurred.
The Remote Power Off (RPO) switch is
active or the RPO connector is missing.
Contact a qualified electrician.
If the UPS Status menu displays the
"Remote Power Off" notice, inactivate the
RPO input.
Silencing the Alarm
Press the ESC (Escape) button on the front panel display to mute the alarm. Check the alarm condition and
perform the applicable action to resolve the condition. If the alarm status changes, the alarm beeps again,
overriding the previous alarm muting.

Question: how do I... Answer
Turn the UPS on?
Verify that all power modules are securely plugged into the
cabinet, and each module secured in it’s slot.
If external battery cabinets are installed, confirm that the DC
emergency disconnect switch button on the back of the cabinet
is closed (pulled out). To close the DC emergency disconnect
switch button, insert the switch key supplied with the cabinet
into the button and turn clockwise 1/2-turn. Pull the button out
to close the switch. Turn the key back counter-clockwise, and
remove the key.
If an external bypass switch is installed, turn the switch to the
LINE or UPS position. Refer to the front panel display and press
the button labeled ON. (If On/Off control is password-protected,
enter your password. Confirm the selection by pressing the
