2.4.4   Connecting Battery Cables 

 

Note 

1. The batteries may have dangerous current. Before connecting battery cables,  make sure that the battery MCBs at the battery 
side are switched off. 

2. If there are no battery MCBs  at the battery side, users should disconnect any one of the  connectors between battery  cells to 
avoid live state of the system after installation.   

3.Be careful not to reversely connect the battery. Otherwise, both the battery and the system will be damaged. 

4.It's forbidden to disassemble battery cables in the up of the battery MCB when the battery input port is still connected. 

 

1. Connect one end of the negative battery cable to the upper terminal of battery MCBs. Connect one end of the 

positive battery cable to the DC positive bus bar. 

2. Connect copper lugs to the other end of the battery cables. Bind the connecting parts with insulating tape, and put 

them beside the battery. Connect the cables to the battery when the DC distribution unit is to be tested. As shown in 

Figure 2-9.

Connecting NetSure 731 A41-S1 Signal Cables 

The standard configuration of the system is M225S controller. The M225S1X1 user interface board is used for 

M225S.M225S controller and M225S1X user interface board cable connection is show in the following:

M225S controller provides two dry contact alarm output ports: DO1 and DO2. DO2 is for LLVD in subrack system. If 

LLVD is selected, it can't be used for dry contact and should be sealed by white tape when out of the factory . If LLVD
