Disconnection of Inverter
For maintenance work or any service work, inverter must be switched off. In normal
operation, switching off is not necessary.
In order to disconnect the inverter from the AC and DC power sources, you should
proceed with the following procedures. Otherwise you will be exposed to lethal
voltages or the inverter will be damaged.
1: Disconnect the external AC circuit breaker and prevent it from connecting again.
2: Rotate the DC switch to the “OFF” position.
Please strictly follow the sequence of the above procedures. Otherwise it will
lead to unrecoverable inverter damage.
3: Wait about ten minutes until the capacitors inside the inverter have discharged.
4: Measure to confirm AC output of inverter at the AC circuit breaker is voltage free.
5: Pull AC connector out of the inverter.
6: Release the locking part of DC connectors by pressing on the ribbing of the locking
hooks with nipper pliers and pull outwards.
