Figure 7: Overview of terminals
Requirements:
☐ Electrical current strength: maximum 8 A
☐ Maximum conductor cross-section: 6 mm²
☐ External diameter of the cable: 9 mm to 16 mm
☐ Material of the conductor: copper
Procedure:
1. Mount the terminal lugs on the DC+ cable and on the DC − cable of the load.
2. On the inverter side, pierce the double-membrane seals with the smaller diameter with a sharp
object from the outside.
3. Lead the cable of the load through the double-membrane seal into the BatFuse and connect it
to terminals L+ and L − on the battery voltage tap (torque: 4.0 Nm to 5.7 Nm).
