Uninstall the Inverter
Uninstall the inverter and wiring box assembly according to the following steps when the inverter needs to be
removed:
Turn off the external AC breaker and/or system disconnect switch using lock-out/tag-out procedures.
Turn off the external DC breaker and/or disconnect switch, if present, and use lock-out/tag-out
procedures. (Skip this step if there is no DC circuit breaker.)
Switch the inverter’s AC disconnect switch to “OFF” position.
Switch the inverter’s DC disconnect switch to “OFF” position.
Wait for 5 minutes to ensure the internal capacitors have been completely discharged.
Measure the AC output conductor terminal voltage against the ground. The meter should now read 0V.
Disconnect the AC and EGC cables referring to “3.3.4 Electrical Installation AC”.
Disconnect the DC cables referring to “3.3.3 Electrical Installation DC”.
