Decommissioning the Inverter

9.1.1 Disconnecting the Inverter

Danger of burns!
Even if the inverter is shut down, it may still be hot and cause burns. Wear protec-
tive gloves before operating the inverter after it cools down.
For maintenance or other service work, the inverter must be switched off.
Proceed as follows to disconnect the inverter from the AC and DC power sources. Lethal
voltages or damage to the inverter will follow if otherwise.
step 1 Disconnect the external AC circuit breaker and secure it against reconnection.
step 2 Rotate the DC switch to the "OFF" position for disconnecting all of the PV string inputs.
step 3 Wait about 10 minutes until the capacitors inside the inverter completely discharge.
step 4 Ensure that the DC cable is current-free via a current clamp.

9.1.2 Dismantling the Inverter

Risk of burn injuries and electric shock!
Do not touch any inner live parts until for at least 10 minutes after disconnecting
the inverter from the utility grid and the PV input.
Before dismantling the inverter, disconnect both AC and DC connections.
