CAUTION Be sure the power being supplied matches the
power required by the equipment.
CAUTION Power supply cords and cables must be
protected. Do not run cords where they can be
stepped on. Protect cables against pinching and
chafing. Pay special attention to locations where
the cables enter or exit an enclosure or make a
sharp bend.
CAUTION
Ensure that the electrical supply is protected by
over-current protection devices as required by
the applicable electrical codes.
4.7 Grounding
For safe operation, all equipment must be properly grounded.
• Connect all equipment on a rack to a common ground.
• Connect the common ground to a site ground.
• The ground wire should be as short as possible, and
follow the straightest path possible.
CAUTION Be sure the equipment grounding follows
applicable electrical codes.
CAUTION Never modify a grounded power plug to connect
to an ungrounded receptacle.
4.8 Testing the Antennas
All antennas for your configuration are tested at the factory to
ensure proper operation. Before installing them on a tower,
mast, or building at the receive site, you should test them on the
ground to ensure that they are operating properly.
CAUTION Test each antenna on the ground before
mounting it on a tower or building.
CAUTION Verify that all packing material has been
removed from the antenna.
To test one or more antennas, follow these steps.
1. Set each antenna, block downconverters (BCDs), and
the receiver on a work table.
2. Connect an RF cable between an antenna and a BCD.
Repeat this until all antennas and BCDs are
connected. Refer to
Figure 4-2 on page 4-6 for
connections details.
3. Connect a UHF cable from each BCD to a BCD
connector at the rear of the receiver. For example, for
a four antenna system, use the BCD1, BCD2, BCD3,
and BCD4 connectors.
