De-energising the inverter

For maintenance work on the inverter, especially on the connections, the inverter must be disconnected from the power supply.

• For work on the AC side, e.g. on the energy meter, the earthing system or the communication connections, it is sufficient to disconnect the AC connection.
• For work on the PV modules or the DC feed lines, disconnect the DC connections.
• When working in the terminal compartment of the inverter, the inverter must be completely voltage-free on the AC and DC sides.
