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
