①Power supply：voltage levels：220V,400V。
Input power supply ① ②fuse or the Electric leakage chopper
Fuse or leaking current breaker
Please use fuse that conform to the rated voltage
and current level of inverter.
②
Be used to control the power of inverter, it palys
a role of protecting the inverter. Used to switch run and

stop is forbidden.
④
③Magnetic control conductor
⑤
Do not use magnetic control conductor for power switch
of the inverter, for which may reduce the inverter life.
