6. On the inverter side, pierce the double-membrane seals with the larger diameter from the
outside with a sharp object.
7. Lead the DC+ cable of the Sunny Island through the double-membrane seal into the BatFuse
and connect it to terminal L+ (torque: 4.0 Nm to 5.7 Nm).
8. Lead the DC − cable of the Sunny Island through the double-membrane seal into the BatFuse
and connect it to terminal L − (torque: 4.0 Nm to 5.7 Nm).
6.3 Connecting the Sunny Island Charger
Figure 6: Overview of terminals
Cable requirements:
☐ Maximum conductor cross-section: 16 mm²
☐ External diameter: 9 mm to 16 mm
☐ Terminal lugs of size M8, maximum width: 16 mm
☐ Material of the conductor: copper
Procedure:
1. Mount the terminal lugs on the DC+ cable and on the DC − cable of the Sunny Island.
2. On the battery side, pierce the double-membrane seals with the smaller diameter with a sharp
object from the outside.
3. Lead the DC+ cable of the Sunny Island Charger
devices through the double-membrane seals into
the BatFuse and connect it to terminal L+
(torque: 4.0 Nm to 5.7 Nm). Always connect two
Sunny Island Charger devices to one terminal.
4. Lead the DC − cable of the Sunny Island Charger
devices through the double-membranes seal into
the BatFuse and connect it to terminal L − (torque: 4.0 Nm to 5.7 Nm). Always connect two
Sunny Island Charger devices to one terminal.
