Disconnecting, Dismantling and
Disposing the Inverter
8.1
Disconnecting the 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 as follows. Otherwise you will be exposed to lethal voltages or the inverter
will be damaged.
Step 1
Disconnect the external AC circuit breaker and prevent it from reconnecting.
Step 2
Rotate the DC switch to the “OFF” position and then pull off all the PV string
inputs
Please strictly follow the sequence of the above procedures. Inverter will
not work normally if otherwise.
Step 3
Wait about ten minutes until the capacitors inside the inverter have
discharged.
Step 4
Loose the six screws on the lower connection cabinet and then remove the
lid.
Step 5
Measure AC voltage to ground at the AC terminal to confirm AC output of
inverter at the AC circuit breaker is voltage free.
Step 6
Loose screws to remove AC cables.
Step 7
Disconnect DC cables from the inverters.
8.2
Dismantling the Inverter
Refer to Chapter 5 and Chapter 6 to dismantle the inverter in reverse steps.
If the inverter will be reinstalled in the future, please refer to 4.4 Storage of
Inverter for a proper conservation.
