3.2.6 Connecting Battery Cables
The connection of battery cables in DC distribution cabinet is described below.
The procedures of connecting battery cables are as follows:
1. Route and number the cables of the 2 batteries and mark their polarities.
2. Connect one end of the negative cable to the output terminal of the battery fuse and one end of the positive cable
to the positive copper bar of the DC distribution cabinet. Add cable lugs to the other end of the positive and negative
cables, bind the cable lugs with insulating tape, and put them beside the battery. Connect the cables to the battery
when the DC distribution is to be initially tested, as shown in Figure 3-21.
Note
The battery negative cables should be connected to the two battery fuses, not the single one.
