supply of all related equipments and ensure mains DC voltage in safe range.
And please operate it after 5 mins.
Away from children and public.
●
Only used in application fields as maker stated. No use in equipments related
●
to special fields such as emergency, succor, ship, medical treatment,
avigation, nuclear and etc.
Unauthorized alteration or use of accessories which are not sold or
●
recommended by the maker may cause faults.
Please make sure this manual is in the final user'hand before using.
●
Before installation and debugging pls carefully read and totally understand
●
these safety regulation and warning signs.
Transport and store regulation
●
Correct transport, store, installation and careful operation and maintenance are
●
important for inverter safe operation.
In transport and store process, make sure the inverter is free from impact and
●
vibration. It must be stored where is dry without corrosive air and conductive
dust, and the temperature must be lower than 60℃.
Installation and wiring regulation
●
Only professional trained person can operate it.
●
Power wire, motor wire and control wire should be all connected firmly. Earth
●
must be reliable and earth resistance must be lower than 10Ω.
Before opening the inverter, please disconnect all related equipment power
●
supply and make sure the mains DC voltage is in safe range and operate after
5mins.
Human body electrostatic will damage inner sensitive components seriously.
●
Before operation, please follow ESD measures. Otherwise, there is danger of
iverter damage.
Inverter output voltage is pulse wave. If components such as capacitor which
●
improves power factor and pressure-sensitive resistance for anti-thunder and
so on are installed at the output side, please dismantle them or change to input
side.
No switch components such as breaker and contactor at the output side. (If
●
there must be one, please make sure the output current is 0 while the switch
acting).
Run regulation
●
Inverter runs at high voltage. So dangerous voltage is in some components
●
inevitably.
No matter where the fault is, there is danger of serious accident, even human
●
body injury what means dangerous malfunction possibility. So there must be
additional external prevent measures or other safety devices, such as
independent current limiting switch, machinery fense and so on.
In order to guarantee the right action of the motor's overload protection, the
●
input parameters of motor to the inverter must be must be in full compliance
with the actual used motor.
