Connecting the power cable of the battery

DANGER

Danger to life from electric shock due to live DC cables at the battery.

The DC cables connected to a battery may be live. Touching the DC conductors or the live components leads to lethal electric shocks.

  1. Ensure that the inverter is disconnected from all voltage sources.
  2. Do not touch non-insulated cable ends.

Procedure:

  1. Remove the adhesive tape from the enclosure opening for DC connection and, if other enclosure openings are to be used, take the sealing plugs out of these enclosure openings.
  2. Insert the cable gland into the opening and tighten it with the counter nut from the inside.
  3. Guide each cable into the inverter. In the process, lay each cable in such a way that they do not come into contact with the communication assembly.
  4. Connect equipotential bonding of the battery to a grounding point:
    • Strip off the conductor insulation by 18 mm.

    • Insert the screw through the conical spring washer, the clamping bracket and the washer.

    • 5370459404
    • Put the conductor between the washer and clamping bracket and tighten the screw (TX 25, torque: 6 Nm ± 0.3 Nm). Here, the conductor must have contact with an inner edge of the clamping bracket.

    • If 2 conductors have to be connected to a grounding point, put both conductors between the washer and clamping bracket and tighten the screw (TX 25, torque: 6 Nm ± 0.3 Nm). Here, each conductor must have contact with an inner edge of the clamping bracket.

  5. Strip off the DC conductor insulation.

  7. Connect the cables according to the labeling. Insert each conductor into the corresponding terminal point.
  8. Ensure that the terminal points are allocated to the correct conductors.
  9. Ensure that the conductors are plugged completely into the terminal points up to their insulation.
