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 clamping bracket, the cylindrical screw M5x16, the washer and the spring lock washer are part of the scope of delivery of the inverter.
Grounding of the battery
The grounding of the battery must not be connected to the connection point for additional grounding on the inverter.
- Ground the battery according to the battery manufacturer's specifications.
Cable requirements:
Use of fine-stranded conductors
You can use an inflexible or a flexible, fine-stranded conductor.
- When using a fine-stranded conductor, it has to be double crimped by a ring terminal lug. Make sure that no insulated conductor is visible when pulling or bending. This will ensure sufficient strain relief by means of the ring terminal lug.
Grounding cable cross-section: max. 10 mm²
Procedure:
- Strip off 12 mm of the grounding cable insulation.
- Insert the screw through the spring lock washer, the clamping bracket and the washer.
- Lightly screw the screw into the thread of the connection point for the additional grounding.
- Guide the grounding cable between the washer and clamping bracket and tighten the screw (TX25) (torque: 6 Nm).
