4.5 Power supply
The CP525 may be delivered rated for AC or DC operation, respectively.
Warning: This product should be operated only from the type of power
source indicated on the marking label. Please consult a qualified electrical
engineer or your local power company if you are not sure of the power
supplied at your premises.
4.5.1 AC power supply
The CP525 has a wide-range power supply accepting the voltage range 100-240 VAC, 50/60 Hz.
Please refer to
Appendix A for a detailed specification of the AC power supply.
4.5.2 Dual AC power supplies
Alternatively, the CP525 may be fitted with dual internal wide-range AC power supplies. If so,
the size of the cabinet is full-width 19" rack, 1RU. The power supplies cover the voltage range
100-240 VAC, 50/60 Hz.
During normal operation, load-sharing is used between the internal supplies. In case of a single
power supply failure alarms will be raised and the unit will continue operating off the second
power supply. To guard against failure in the external power circuitry it is imperative to connect
each power supply to separate AC mains circuits.
Please refer to Appendix A for a detailed specification of the AC power supply.
4.5.2.1 AC power cable
Ensure that the AC power cable is suitable for the country in which the unit is to be operated.
Caution: Power supply cords should be routed so that they are not likely
to be trod on or pinched by items placed upon or against them. Pay
particular attention to cords at plugs and convenience receptacles.
The unit is supplied with a two meter detachable mains supply cable equipped with a moulded
plug suitable for Europe, UK or USA, as appropriate. The wires in the mains cable are coloured
in accordance with the wire colour code shown in
