System Voltage
All units connected to the system voltage in the RBS work within the
voltage range 20.0 - 29.0 V DC.
5.4.2 Battery Back-up
The battery back-up can be either internal or external (that is, a source
of battery supply outside the cabinet is connected via the DC filter).
Batteries can be installed inside the cabinet in either of the TM/battery
spaces located to the left of the BFU. The battery space can be
converted to TM space, and the TM space can be used for batteries.
There are three configurations of battery back-up available:
•
Internal battery: Two or four blocks of batteries are installed in
the TM/BM space to the left of the BFU. Batteries must all be of
the same type. The TM space remains available for optional
transmission equipment.
• Expanded battery: Also called internal and expanded battery. The
space for TM equipment is used for additional battery capacity.
All blocks in the internal battery back-up must be of the same
type. Transmission equipment cannot be installed in the TM.
• External battery: A +24 V DC battery source outside the cabinet
can be connected via the DC filter. One 200 A external fuse is
used.
Note: No internal battery is allowed when an external battery
back-up is used.
In all configurations, connection or disconnection of the batteries is
supervised by the Battery Fuse Unit (BFU). In addition to supervising
