6.2.3 Connecting Additional Grounding
If local requirements stipulate the connection of additional grounding or equipotential bonding, you
must connect additional grounding to the inverter. This prevents touch current if the grounding
conductor at the connecting terminal plate for the AC cable fails.
Cable requirement:
☐ Grounding cable cross-section: max. 10 mm²
Procedure:
1. Strip the grounding cable insulation. If you are using a grounding cable with double insulation,
strip the outer insulation by 120 mm.
2. Release the screw using an Allen key (AF 5),
until the grounding cable can be led under the
clamping bracket.
3. Feed the grounding cable under the clamping bracket. Position the grounding conductor on
the left-hand side.
4. Tighten the clamping bracket with the screw and conical spring washer (torque: 6 Nm). The
teeth of the conical spring washer must face the clamping bracket.
