Figure 2-30 Battery cable connection for long back-up UPS
Connecting the long back-up UPS and the battery module
When you need to connect the long back-up UPS and the battery module, a battery cable A (standard UPS accessory)
is necessary, as shown in Figure 2-22. The battery cable A is used to connect the battery module and the long back-up
UPS.
The connection procedures are as follows:
1. Make sure that all the external input MCBs and output MCBs of the UPS are open.
2. Use voltmeter to measure and confirm that there is no DC voltage on the battery port on the UPS rear panel (see
Figure 1-3).
3. Connect the red, black and yellow terminal of one end of the battery cable A to the corresponding terminal of the
battery port on the rear panel of the UPS, and connect the other end of the battery cable A to one of the battery ports of
the battery module 1, as shown in Figure 2-26.
4. Connect one end of the accessory cable of the battery module to the other battery port of the battery module 1, and
connect the other end of the accessory cable of the battery module to one of the battery ports of the battery module 2.
Follow this step to connect other battery modules.
