5.2 Site Power Options
The RBS cabinet has three power source options:
•
120 - 250 V AC mains input power through screw-terminals. The
power inputs feed four separate PSUs. A battery back-up
+24 V DC may be connected simultaneously as an option. This is
the same as the +24 V described below.
• +24 V DC. The radio cabinet can operate on +24 V DC from an
external power source.
•
-(48 - 60) V DC is connected in a similar manner as the AC.
Observe that the +24 V DC battery back-up is not available in
this power configuration.

DANGER
Improper electrical installation may cause fire or electrical shock.
Approved circuit breakers for the AC mains and the cable’s cross
sectional areas must always be selected in accordance with local
laws and regulations. Only a qualified and authorized electrician
is permitted to install or modify the electrical installation.
The RBS 2206 can be delivered in two versions. The first version has
power interface inlets for one AC mains supply voltage and one inlet
for DC power: +24 V DC. The other version has power interface for
-(48 - 60) V DC, see table below.
