Power Supply
The R FR 5010 / R FR 5011 includes the primary
power supply. A second identical power supply
can be added for redundancy. The Power supply is
a sophisticated design designed for critical
applications and includes power filtering and
integral microprocessor. This monitors the supply
operation and reports into the control system.
Should a fault develop, the errors are alarmed in
the following ways:
• Via the LED located on the front of the supply
(Figure 4).
• Via a GPO alarm via the alarm connector on
the termination panel (figure 5), if a controller
option is fitted
• Via the control system (if installed)
If the redundant power supply is installed, the
system will switch supplies automatically in the
event of primary supply failure, with no interruption
to the normal operation of the rack.
The supply has a noiseless integral DC fan for
cooling.
The supply is installed and removed from the front
of the rack. Removing the rack front cover plate
provides access. The supply is secured firmly in
place with a screw located at the bottom front of
the unit (figure 4).
