8 Disconnecting, Dismantling and
Disposing the Inverter
8.1 Disconnecting the Inverter
For maintenance work or any service work, inverter must be switched off. During
normal operation, switching off is not necessary.
Proceed as follows to disconnect the inverter from DC and AC power sources
Step 1
Disconnect the external AC circuit breaker and prevent it from accidental
reconnecting.
Step 2 Turn off the upstream DC circuit break. Rotate DC switch to the “OFF” position.
Please strictly follow the above sequence. Inverter will not work normally if
otherwise.
Step 3 Wait about ten minutes until the
capacitors inside the inverter have been
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 voltage of
inverter at the AC circuit breaker is zero.
Step 6 Remove the AC cables.
Step 7 Remove the DC cables.
8.2 Dismantling the Inverter
Refer to Chapter 5 and Chapter 6 to dismantle the inverter in reserve steps.
If the inverter will be reinstalled in the future, please refer to “4.4 Inverter
Storage” for a proper conservation.
