The frames come standard with one auto-ranging power supply that automatically senses the input
voltage over the range of 100 to 240 VAC. An additional power supply can be ordered to provide fully
redundant powering of the frame. When only one power supply is fitted, the frame will be fitted with the
appropriate fan module (7800PS-FM, 7800PS-QT-FM or 7800PS-Q-FM) 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.
CAUTION - TO REDUCE THE RISK OF ELECTRIC SHOCK, GROUNDING OF THE
GROUND PIN OF THE MAINS PLUG MUST BE MAINTAINED
The power entry modules contain a standard IEC power inlet connector, two 5 x 20 mm fuse holders and
an EMI line filter.
Fuse Rating: 6.3 amps, 250 Volt ceramic time delay
See section 5.1 for information on changing the fuses.
If there is a fuse failure, contact Evertz customer service regarding the power
supply immediately. The power supplies are short circuit protected and should
not blow the fuse under a short circuit condition.
