1. To shut off the inverter at the grid, open the load-break
switch between the inverter and the grid connection point.
Secure the load-break switch to prevent it from being
switched back on.
2. Turn both DC disconnectores to the OFF position.
3. Wait at least 60 seconds until the internal capacitors have
discharged.
Always use the supplied mounting tools to open
the DC connectors.
When disconnecting the DC cables, take care not
to damage the connectors.

Pull out at the DC connector, not at the DC cable.

pull them out.
