Connecting Additional Grounding


Qualified person

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.

Cable requirement:

  • Grounding cable cross-section: max. 10 mm²

Procedure:

  1. Strip the grounding cable insulation.

  3. Release the screw using an Allen key (AF 4) until the grounding cable can be led under the clamping bracket.
  4. Feed the grounding cable under the clamping bracket. Position the grounding conductor on the left-hand side.
  5. 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.
