8.2.2 Disconnecting the Inverter
Danger of burns!
Even if the inverter is shut down, it may still be hot and cause burns. Wear protec-

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 25 minutes until the capacitors inside the inverter completely discharge.
step 4 Ensure that the DC cable is current-free via a current clamp.
