Reference Manual R FR 5010 Version1.4
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).
