3.6 Attention for Main Circuit Wiring
3.6.1 Power Supply Wiring
It is forbidden to connect the power cable to the inverter output terminal, otherwise, the internal
components of the inverter will be damaged.
To facilitate the input side overcurrent protection and power failure maintenance, the inverter shall
connect to the power supply through the circuit breaker or leakage circuit breaker and contactor.
Please confirm that the power supply phases, rated voltage are consistent with that of the nameplate,
otherwise, the inverter may be damaged.
3.6.2 Motor Wiring
It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal
components of the inverter will be damaged.
