Product Data
It is possible to supply external transmission equipment from the battery
cabinet. The transmission equipment is provided with power supply
longer than the RBS.
In event of mains failure, the batteries in the BBS 2000 will deliver the
necessary power to the radio cabinet as well as to the transmission
equipment, if used. This enables the radio system to operate during
mains failure.
The battery back-up can be delivered for 1, 2, 4, 6 or 8 hours back-up
time, depending on the chosen configuration of the RBS.
The BBS can feed +24 V DC or -48 V DC to the TM equipment. The
-48 V DC supply requires an internal DC/DC converter in the BBS.
It is possible to share battery back-up between RBS 2202 and
RBS 2206.
5.6.1 Converting BBS 2202
If BBS 2202 is used, a conversion kit is needed to run RBS 2206. The
battery fuse unit determines which conversion kit should be used:
BFU-21: product number BMY 201 237/5
BFU-22: product number BMY 201 237/6

Predefined voltage +27.2 V DC
Battery low voltage limit +21.0 V DC

Battery Fuse Unit
The battery fuse unit (BFU) monitors and controls the batteries. It will
cut off the load (the RBS) when any of the following conditions occur:
• A mains failure lasts longer than the back-up time. When the
battery voltage drops below a preset value, the BFU disconnects
the RBS. This is to prevent damaging the batteries by over-
discharging. The BFU continues to feed the transmission
