Installing the Equipment

Allow at least 40 mm free air space at each side of the equipment to ensure

adequate cooling. Units in racks can be stacked with no space in between. Racks

containing stacked equipment may need to be forced air-cooled to reduce the

ambient temperature within the rack.

2.3.2.3 Protection from Moisture

Do not install this unit in areas of high humidity or where there is a danger of water

or moisture entering the equipment.

2.3.3 Installing Cables – Safety

Warnings!

When connecting the F-connector cable from the antenna to the QPSK F-connector

input, it is important to make sure that:

The unit is properly grounded.

The cable screen is the first point of contact between the F-connector and the

cable.

This is to make sure that the cable and unit are at the same electrical potential when

the connection is made, and to avoid damage to the equipment.

Power supply cables should be routed so that they are not likely to be walked on or

pinched by items placed upon or against them. Pay particular attention to cables at

plugs, convenience receptacles, and the point where they exit from the appliance.

Do not run AC power cables in the same duct as signal leads. Do not move or install

equipment whilst it is still attached to the mains supply. Ensure that safety and ESD

precautions are observed whilst interconnecting equipment.
