4.10 Battery Cable and Connection

If ordered, battery cables are pre-connected to the system battery breakers.  If not, use suitably 
rated cable size (see Table 4-1 on page 22) and follow steps 1 to 4 below.

Battery Connection Points on the PBDU and Battery Distribution are shown in Figure 4-9.

1.  Check that all the battery MCBs are in the OFF position.

2.  Connect the “+” cable of each battery string to the positive bus bar of the system.  Tighten 

the cable terminal to 3.0Nm.

3.  Connect the “-“cable of each battery string the battery circuit breaker.  The copper bar 

with washer and nut installed on the circuit breaker is used to connect and tighten the 
battery cable lug.

4.  Connect the other ends of the battery cables to the “-“and “+” terminals of the batteries 

as described in section 4.11. 

Use Torque table in the Maintenance and Troubleshooting Chapter for the correct torque.

NOTE

  Figures 4-7 and 4-8 show a configuration with six battery breakers installed.
