Connecting Additional Grounding

Qualified person

If additional grounding or equipotential bonding is required locally, you can connect additional grounding to the product. This prevents touch current if the grounding conductor at the terminal for the AC cable fails. The required M5x16 screw, the washer, and the conical spring washer are included in the scope of delivery of the inverter.

Additionally required material:

  • 1 ring terminal lug

Procedure:

  1. Strip the grounding cable insulation.

    3. 13316745228
  3. Insert the screw with conical spring washer through the hole in the ring terminal lug and washer and tighten the ring terminal lug with the screw to the connection point for additional grounding with a Torx screwdriver (TX25) (tightening torque: 2.5 Nm).
