Making the DC connection
1. DC cables must be voltage free. Check that the device is voltage-free.
2. Prepare connection cables from batteries B+ and B-, the precharge and sense cables as well as the optional
centre point monitoring cables.
3. Remove the knock-outs for the cable screw fittings at the required points.
4. Fit the cable screw fittings
5. Insert the DC leads through the cable fitting into the connection area.
6. Remove the outer cladding from the cables
7. Remove the insulation from DC- sense minus cable and connect to the terminal "precharge B-" using the tool
8. Remove the insulation from DC- sense plus cable and connect to the terminal "precharge B+" using the tool
9. Remove the insulation from mid-point monitoring lines and connect to "precharge B mid" terminal
10. Remove the insulation from DC- minus cable and use a hex bolt and the tool provided to connect to the
minus pole.
11. Remove the insulation from DC- plus cable and use a hex bolt and the tool provided to connect to the plus
pole.
12. Close the connection terminals.
13. Check that all connected cables are securely fitted.

< 5-10 m 70 mm 2
> 10 m not recommended
Table 4: Recommended minimum cross-section for battery copper cable
NOTE
Depending on the installation type, ambient temperature and the required voltage drop, a cable
cross-section greater than the minimum cross-section can be used (50mm²).
