Chapter 1 Safety Precautions
1
.1 Safety precautions
The 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 wiring. 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 an 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 for 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 an overcurrent happens during starting up, please check the
wiring and start up again.
Do not stop the machine by cutting off power. Power can be
cut off after the motor stops.
Do not leave the inverter in the sunshine. Otherwise, it may
cause damage to the inverter.

Chapter 10 Maintenance and Repair
Due to the environmental influences such as temperature, humidity,
dust, and vibration etc., and aging components, the inverter may fail at
some time. So it needs periodic maintenance and repair.
Notice: please check the following items before maintenance
and repair. Otherwise, it may cause electronic shock.

.
Power source is cut off.
. Indicator on panel is OFF.
. Maintenance is performed by professionals.

0.1 Daily maintenance and repair
The Inverter must be installed in the standard environment
according to this manual. There may be some unexpected situations
during runtime. Please do daily maintenance work according the
following table. Keep a good runtime environment, log daily data and
detect fault causes early. It can extend the life of the inverter.

0.2 Periodic maintenance
The Inverter needs periodic maintenance every 1 or 3 months which
depends on the runtime environment.
Notice: Machine maintenance or component replacement 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！

Whether the main loop port is loose or not. Or is there
any sign of overheating in the line of the main loop;
、 Is there any trauma in the power and control cable?
Especially, check the robber skin in the contact with other metal;
、 Is the insulation bandage of the power cable loose;

、 If the motor needs examination, please disconnect the
motor wire from inverter’s U,V,W port. Otherwise, it may
cause fatal damage to the inverter.
Notice: Inverter has already passed the pressure test. Any
the improper test may cause fatal damage to the inverter!

0.3 Replace the wearing parts
The wearing parts contain a cooling fan and filter electrolytic
capacitor whose lifetime depends on environment and load. When
the temperature is 25℃, the lifetime of th e cooling fan is
20~40Kh and that of the capacitor is 30~50Kh. Users can decide
when to replace these components.

.
Cooling fan
Cause of damage: wear bearing, aging fan, heavy dust
environment.
Criterion: rip in fans, abnormal vibration during
runtime.

.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.

0.4 Store of inverter
Precautions for storing inverter:
1
.
It cannot be stored in high temperature, moist, dusty,
metal dust, corrosive gas places.
It will speed up the capacitor aging during long-time store.
2
.
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.
0.5 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.
Costs can be counted as listed on contract or actual cost.
