Connecting battery cables
NOTE! 1. The batteries may have dangerous current. Before connecting battery cables, make sure that the
battery fuses at the system side and the battery MCBs at the battery side are switched off. 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 power system after installation.
2. Be careful not to reversely connect the battery. Otherwise, both the battery and the power system will be
damaged!
3. When the load capacity exceeds 200A, it is recommended to connect two routes of batteries.
1. Connect one end of the negative battery cable to the upper terminal of the battery fuse. Connect one end of the
positive battery cable to the DC output positive busbar. The specifications of the positive busbar connection screw is
10mm.
2. Connect OT lugs to the other end of the two battery cables. Wrap all the bare parts with insulating tape and put
them beside the battery. Do not connect the cables to the battery until the DC distribution unit is to be tested.
