11 Shutdown/Disassembly
11.1 Shutting down the inverter
DANGER
Lethal voltages are still present in the terminals and leads of the inverter even after the
inverter has been switched off and disconnected.
Severe injuries or death if the leads and terminals in the inverter are touched.
› After shutdown, wait at least 5 minutes before working on the inverter.
› When working on photovoltaic modules, in addition to disconnecting from the grid, always discon-
nect the DC main switch on the generator junction box (or the DC plug connectors). Disconnecting
the grid voltage is not enough.
DANGER
Destruction of the DC plug
DC plugs can be destroyed by arcing when being disconnected under load.
› It is absolutely necessary that the shutdown sequence be carried out in the correct order.
Shutdown sequence
1. Switch off the grid voltage by deactivating the external circuit breakers.
2. Disconnect the PV generator using the DC disconnect.
DANGER! The DC leads remain live.
 Ensure that there is no voltage present on the grid connection terminals.
11.2 Deinstalling the inverter
↻ Shut down the inverter.
1.
Open the connection area.
2. Remove the interface cable.
3. Release the DC and AC leads from the spring-type terminals.
4. Open the cable fi ttings.
5. Pull out the leads.
