Connection to peripheral divices
Do not install the capacitor or surge suppressor at the output side of the inverter, otherwise

it may cause inverter failure or capacitor and surge suppressor damaged.
The Inverter input / output (main circuit) contains harmonic components, it may interfere

with inverter accessories communications equipment. Therefore, install anti-interference
îš¿lter, make minimize interference.
The details of peripheral equipments and accessories selection refer to the manual of

To insure the safety, please use electromagnetic contactor.Please do
not use the electromagnetic contactor to start and stop the inverter,
otherwise,it will reduce the lifetime of the inverter.
Suppress the high order harmonic to improve the power factor.
In order to prevent electric shock, the motor
and inverter must be well grounded.
It can give full play to the regenerative capacity of the inverter, please
use according to needs.
To insure the safety, please use electromagnetic contactor.Please do
not use the electromagnetic contactor to start and stop the inverter,
otherwise,it will reduce the lifetime of the inverter.
Three-phase AC power supply
Please use the power supply which is within the inverter
specification
