2.5 Parallel Connection Of Cabinets

In order to prolong the backup time of battery, the battery capacity should be increased. Another cabinet can be connected in parallel with the DC power system cabinet. The expanded cabinet has no rectifier shelf and Multi-Function Unit. It is only installed with battery strings and a BCU. So, it is actually the battery cabinet. BCU in Extension Unit connects to Main Unit through cables. The parallel connection of the DC power system cabinet with the battery cabinet is shown in Figure 2-19:

DC/Parallel connections

The DC cables are connected to the output of the rectifier shelf in the MFU.

Up to two Battery Connection Units (BCUs) can be connected in the DC Power System – up to one BCU in the main cabinet and up to one BCU in an extension battery cabinet.

SCU can display the alarm signals from these two BCUs.

The user can connect the MFU to an additional extension MFU (only for additional load circuit breakers) through suitably rated cables.
