Connecting Additional Grounding

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 at the terminal for
the AC cable fails. The required clamping bracket, the screw and the conical spring washer are
part of the scope of delivery of the inverter.
Cable requirement:
☐ Grounding cable cross-section: 16 mm² at maximum
Procedure:
1. Strip the grounding cable insulation.
2. Lead the clamping bracket over the grounding
cable. Arrange the grounding cable on the left-
hand side.
3. Screw the clamping bracket tight using the
M6x16 cylindrical screw and the conical spring
washer M6 (torque: 6 Nm). The teeth of the
conical spring washer must face the clamping
bracket.
