The 500FR frame comes standard with one auto-ranging power supply that automatically senses the input
voltage. An additional power supply (500PS) can be ordered to provide fully redundant powering of the
frame. When only one power supply is fitted, the frame will be fitted with a 500PS-FM fan module to
ensure the thermal integrity of the frame cooling. Power should be applied by connecting a 3-wire
grounding type power supply cord to the power entry module on the rear panel of each power supply.
The power cord should be minimum 18 AWG wire size; type SVT marked VW-1, maximum 2.5 m in
length.
The power entry modules contain a standard IEC power inlet connector, two 5 x 20 mm fuse holders and
an EMI line filter.
CAUTION - TO REDUCE THE RISK OF ELECTRIC SHOCK, GROUNDING OF THE
GROUND PIN OF THE MAINS PLUG MUST BE MAINTAINED

Each 500PS power supply is fitted with its own power switch. When the switch is turned off, the remaining
power supply will power the 500FR frame. To completely remove power from the frame, both power
supplies must be turned off.
