Set unbalanced load limitation
| The tasks described in this section may only be carried out by a qualified electrician. |
Unbalanced load refers to the uneven loading of the phases of a three-phase alternating current network. In Germany, for example, the maximum difference between two phases at the mains connection point is 20 A (in accordance with VDE-N-AR-4100).
- If an external energy meter is not connected, the unbalanced load of the product is limited.
- If an external energy meter is connected, the charging current is regulated taking account of the unbalanced load from all measured consumers.
- Observe applicable national regulations.
- Set DIP switch 2 on bank S1 to "ON".
- The unbalanced load is limited to 20 A (default setting).
To limit the unbalanced load to a different current value, the configuration tool is required.
