| **Depending on the power of the charger, choose the appropriate cross-section of the power supply cable and the appropriate fuse. The connection terminals in the charger enable the connection of a cable up to 10mm2. If you have a charger model without a RCD switch, you must install it before the power supply cable.**  |
