Many Rack PDU G4 models have both IEC 60320 C13 outlets, as well as a proprietary Eaton C39 combination
outlet. This C39 outlet is a combination of C13 and C19 outlet styles, and it is designed to accept both C14 and
C20 plugs.
PDUs with these outlets are also designed to have native high-retention, which makes it more difficult for the
plug to be removed. When removal of a plug is necessary, wiggle it from side to side while pulling on it.

• Simplified installation lets you install the EMP safely without turning off power to the Rack PDU or to the
devices that are connected to it.
• The EMP monitors temperature and humidity information of any environment, protecting your critical
equipment. The EMP measures temperatures between 0°C and 70°C (32°F and 158°F) with an accuracy
of ±2°C. The EMP measures relative humidity between 10% and 90% with an accuracy of ±5%.
• The EMP can be located away from the Rack PDU with a Category 5 network cable up to 50m (165 ft)
long.
• The EMP monitors the status of two user-supplied contact devices.
• Temperature, humidity, and contact closure status can be displayed through a variety of interfaces.
• User-selectable alarm thresholds let you define acceptable temperature or humidity limits.
• You can use e-mail client software to set up e-mail notification through Simple Network Management
Protocol (SNMP) when acceptable alarm limits are exceeded or contact status changes.
• Changes in external contact status are logged in the Rack PDU event history log.
• When temperature and humidity values exceed user-selectable limits, the event is logged in the Rack PDU
event history log.

Most cordsets have a plug, and they should be connected to a matching receptacle.
A few cordsets have pigtails. These can be wired directly into an electrical junction box or busway tap-off box.
This connection must be performed by a qualified electrical worker in conformance with local electrical codes.
Note that the PDU+cordset connector pair is rated by UL and IEC as a disconnect device.

For Universal Input PDUs with G4 network card, the PDU input measurement mode defaults to "Auto-detect".
In some cases this detection may be incorrect, and the mode may need to be manually configured in order to
have proper display of input measurements and alarms. Additionally, input current warning and critical
thresholds will always need to be configured to match the rating of the input plug. This configuration is done
using the following steps. See the communication quick-start for details on how to make a connection and log
in.
TToo uussee tthhee wweebb iinntteerrffaaccee::
1. On the PDU Settings webpage, click the General tab.
2. In the Input Measurement Mode box, choose the option based on the table below
3. Set the input current high warning and critical thresholds on the Input Thresholds tab to match the input
plug and desired alarm levels.
4. Save the changes and reboot.

The Rack PDU outlets are available for connecting and monitoring devices such as workstations, servers, and
switches. Connect a device you want to monitor to a power outlet on the Rack PDU with the power cord that
comes with the device.
NNOOTTEE You may find it useful to document the connections you make.
To connect your devices:
1. Verify that each circuit breaker is in the On position.
2. FFoorr RRaacckk PPDDUUss wwiitthh ddeettaacchhaabbllee ppoowweerr ccoorrddss.. If the power cord is not connected, connect the power
cord to the Rack PDU. Otherwise, go to Step 3.
3. Route the Rack PDU power cord toward a dedicated power source. If desired, use cable ties to secure the
power cord as needed. If the power cord must exit the rack cabinet to connect to a power source, use the
openings in the rack cabinet.
NNOOTTEE 11 Plug the Rack PDU into an appropriately rated outlet for its type.
NNOOTTEE 22 Do not replace or rewire the power cord.
4. Connect the power cord to a properly wired and grounded dedicated power source. The Rack PDU turns
on and displays an Eaton startup screen while starting. After a period of inactivity, the LCD screensaver will
begin cycling through different screens.
5. Connect your output devices to the outlets on the Rack PDU. Verify that each device is receiving power
before connecting the next device.
NNOOTTEE To avoid large surge currents, connect the protected equipment to the outlets
individually rather than as a group. You may want to include a delay for Switched and
Managed models when setting up groups of outlets to start at the same time to avoid a
large in-rush current.
6. Route all power cords neatly. If desired, use cable ties to secure the cords.
