Figure 6 RBS 2107 Overview
5.1 Standard Hardware Units
This section briefly describes the standard hardware units required, irrespective
of configuration or frequency.
ACCU-32
The AC Connection Unit (ACCU) connects, disconnects, and distributes the
incoming AC power supply to the PSUs and the climate unit.
Number of units: 1
BFU-21
The Battery Fuse Unit (BFU-21) supervises the connection or disconnection
of the batteries. It can also be used to provide prioritised power supply, for
example, to the transmission equipment.
Number of units: 1
Climate Unit
The climate unit maintains the temperature and humidity inside the cabinet.
The climate unit is mounted in the door of the cabinet. The heat exchanger
climate unit provides heating and cooling through forced convection. It has no
refrigerating capacity; so the cabinet cannot be cooled to a temperature lower
than the outside (ambient) temperature.
