Grounding the Battery

Qualified person

Additionally required material (not included in the scope of delivery):

  • A suitable grounding cable with ring terminal lug for the connection of the additional grounding via an external grounding point.

  • At least 1 longer grounding cable is required to connect the battery modules to each other (minimum length: 1.5 m) if they are not mounted directly above each other. This is unavoidable for:

    • 4 or 5 battery modules

    • Back-to-back

Requirement:

  • Make sure that the battery modules were correctly mounted.

Procedure:

  1. Disconnect all products from voltage sources.

  2. Connect battery modules mounted directly above each other via the supplied grounding cable. To do this, tighten the provided screw and washer assemblies at the connection points closest to each other (TX20; torque: 2.5 Nm). For batteries not directly mounted above one another, use a longer grounding cable.
  3. Strip off the insulation of a grounding cable suitable for the external grounding and crimp a supplied terminal lug to the cable.

  4. Tighten the provided screw and washer assembly at the lower connection point for the additional grounding (TX20; torque: 2.5 Nm).
  5. Connect the grounding cable to the external grounding point. The external grounding points of battery and inverter must have the same potential.
