Chapter 2 Installation

Note

The actual number of battery circuit breakers in MFU may be 0~5 according to the user’s need.

Non-standard configuration

The DC power system with non-standard configuration has a BCU. The connection of positive cables is the same with that of the system with standard configuration. The only difference is that there are five positive battery cables because the system has five battery strings. One end of positive battery cable is connected to the neutral bus of the DC power cabinet. Another end of the positive battery cable is connected to the positive terminal of the battery string in each level as shown in Figure 2-17.

One end of negative battery cable is connected to the negative terminal of the battery string in each level as shown in Figure 2-17. Another end is connected to the BCU as shown in Figure 2-18. The connection has already been done in factory.

Negative Battery Cables(Blue)

Note

1.Before connecting the battery cables, the corresponding battery fuse or the battery switch must be disconnected.

2.Be careful not to reverse connect the battery, otherwise, the battery and the power supply system will be damaged!

Since the battery voltage decreases in discharge, hence the sectional area of the cable connecting the battery and the MFU or BCU should be relatively big to keep the voltage drop on the cable within 0.5V.
