Connecting battery module cables
It is recommended to use four battery modules for power supply, including two positive battery modules and two
negative battery modules, using one-into-multiple battery cables (optional) to connect. The cables of the positive
battery module are shown in Figure 2-25, and the cables of the negative battery module are shown in Figure 2-26.
Connect the Bat+, Bat-N, Bat- and PE terminal to the corresponding terminal of the UPS, and the terminals of the
other end (color: red, black and yellow) to the corresponding terminals of the battery module.
