5.4.3 Second protective grounding connection
If additional grounding or equipotential bonding is required locally, you can connect
additional grounding to the inverter. This prevents touch current if the grounding
conductor on the AC connector fails.
Procedure:
1. Insert the grounding conductor into the suitable terminal lug and crimp the contact.
2. Align the terminal lug with the grounding conductor on the screw.
3. Tighten it firmly into the housing (screwdriver type: T20, torque: 1.6Nm).

5.5 DC Connection
Danger to life due to high voltages in the inverter
Touching the live components can lead to lethal electric shocks.
• Before connecting the PV generator, ensure that the DC-switch is switched
off and that it cannot be reactivated.
• Do not disconnect the DC connectors under load.
