Reference
2.3.4.1.
Video Reference
There must be an analog reference present (NTSC or PAL) to ensure that the crosspoint changes
occur during the field-blanking interval. If the reference is missing, then the routing will occur
asynchronously. Looking at the back of the EMX frame, either PAL should be connected to the
reference connector on the left-hand side of the frame; NTSC should be connected to the reference
connector on the right-hand side of the frame, or both.
2.3.5.
Power Supply
The EMR router power supplies operate on 100 to 240 volts AC at 50 or 60 Hz and automatically sense
the input voltage. Power should be applied by connecting a 3-wire grounding type power supply cord to
the power entry module on the rear panel. The power cord should be a minimum 18 AWG wire size;
type SVT marked VW-1, maximum 2.5 meters in length.
CAUTION – TO REDUCE THE RISK OF ELECTRIC SHOCK, EARTHING OF
THE EARTH PIN OF THE MAINS PLUGS MUST BE MAINTAINED
For NEBS-compliant installations, the AC power cords of the EMR Router
shall be connected to an external surge protection device (SPD).
The power entry modules contain a standard IEC power inlet connector and an EMI line filter. A
separate fuse holder is located inside the power supply module.
Fuse Rating:
EMR-32x32-3G Series: 6.3A, 250V ceramic time delay (5 x 20mm – 2 per power supply)
2.3.6.
Grounding and Bonding-NEBS Applications
The NEBS-compliant version of this equipment is to be connected to a
Common Bonding Network.
The primary grounding mechanism of the EMR router is through the Earth connector of the AC mains.
For NEBS-compliant installations, the AC power cords of the EMR Router
shall be secured using retaining clips provided to ensure that proper
grounding of the Earth pin of the AC mains plug is maintained.
