Chapter 1 Safety Precautions
1.1 Safety precautions
Environment cannot contain any explosive gas.
It must be wired by professional wiring staff. Otherwise, it
may cause electronic shock.
Cut off the power supply before wring. Otherwise, it may
cause electronic shock.
Do not touch any control port, internal boards and their
electronic components while the electricity is turned on.
Otherwise, it may cause electronic shock.
Please make sure that the product’s ground wiring port is
correctly connected according to national electricity safety
standards or other related standards.
Do not touch any internal board or component until 10
minutes after power shutdown. Please do electricity check
before internal board maintenance. Otherwise, it may cause
electronic shock.
It is forbidden to connect AC power to product’s output port
(U,V,W) or other control ports except Lk,Lb,Lz. Otherwise, it
may cause damage to the inverter.
Since internal IC can be destroyed by electrostatic, please do
not touch any PCB, IC or IGBT components without any
protection. Otherwise, it may cause unknown fault.
Make sure that any unexpected conductor such as screws,
gasket, etc., is not left inside the inverter during maintenance.
Otherwise, it may cause damage to the inverter or even fire.
If overcurrent happens during starting up, please check the
wiring and start up again.
Do not stop machine by cut off power. Power can be cut off
after the motor stops.
Do not leave inverter in the sunshine. Otherwise, it may cause
damage to the inverter.

point move and “→” to anticlockwise point move.
8.5 Point move by external signal
Command（Pn 04）must come from port “FWD/REV”（=2）. Frequency

Chapter 10 Maintenance and Repair
Due to the environment influence such as temperature, humidity,
dust and vibration etc., and aging component, inverter may be fail at
some time. So it needs periodic maintenance and repair.
Notice: please check following items before maintenance
and repair. Otherwise, it may cause electronic shock.
1. Power source is cut off.
2. Indicator on panel is OFF.
3. Maintenance is performed by professionals.
10.1 Daily maintenance and repair
Inverter must be install in the standard environment according
this manual. There may be some unexpected situation during
runtime. Please do daily maintenance work according following
table. Keep good runtime environment, log daily data and detect
fault cause in an early time. It can extend the life of inverter.

A2 Inverter (0.75-30kW)
10.2 Periodic maintenance
Inverter needs periodic maintenance every 1 or 3 month which
depends on the runtime environment.
Notice: Machine maintenance or components replace must be
performed by professionals. If any metal objects such
screws or washer are left inside the machine, it would
cause fatal damage to the inverter！
Check itmes：
1、 Whether the control port screws are loose or not;
2、 Whether the main loop port are loose or not. Or is there
any sign of overheated in the line of main loop;
3、 Is there any trauma in power and control cable. Especially,
check the robber skin in the contact with other metal;
4、 Is the insulation bandage of power cable loose;
5、 Use vacuum cleaner to clean dust on board and ventilation
channel;
6、 If the motor needs examination, please disconnect the
motor wire from inverter’s U,V,W port. Otherwise, it may
cause fatal damage to inverter.
Notice: Inverter has already passed the pressure test. Any
improper test may cause fatal damage to inverter！
10.3 Replace the wearing parts
The wearing parts contain cooling fan and filter electrolytic
capacitor whose lifetime depends on environment and load. When
the temperature is 25℃, the lifetime of cooling fan is 20~40Kh
and that of capacitor is 30~50Kh. User can decide when to replace
these components.
1. Cooling fan
Cause of damage: wear bearing, aging fan, heavy dust
environment.
Criterion: rip in fans, abnormal vibration during
runtime.
21
A2 Inverter (0.75-30kW)
２. filter electrolytic capacitor
Cause of damage: high environment temperature,
frequently load change, long-time
fully load.
Criterion: liquid leak, wrong position of safety valve,
capacity measurement.
10.4 Store of inverter
Precautions for storing inverter:
1. It cannot be stored in high temperature, moist, dusty,
metal dust, corrosive gas places.
2. It will speed up the capacitor aging during long-time store.
Make sure that turn on inverter once every year. The operation time
cannot below 8 hours. And the input voltage increases slowly to the
rating value.
10.5 Warranty
Range: inverter itself;
If any following situation happens, Isacon will provide warranty:
Any fault or damage happens during the standard use in 18
months. Beyond 18 months, Isacon will charge for the maintenance
and repair;
If any following situation happens, even in 18 months, Isacon still
can charge for maintenance and repair:
ａ、damage caused by wrong operation；
ｂ、damage caused by voltage abnormal and nature disaster
such fire and floods etc.;
ｃ、apply inverter in non-standard user case.
