Power LED: Green = Power; Red = Short (check cable and connections).
4.

Fixing:
Fix the power unit to a sound vertical surface such as a wall, skirting board or equipment mounting board.
Ventilation gaps of at least 50mm should be left around the front and sides of the unit. More clearance will be
required below the unit to allow access for the signal cables. Do not leave the power unit resting on a carpet or
install it where it may become smothered with curtains or other soft furnishing fabrics. When installing the power
unit in a roof space ensure that it will not come into contact with thermal insulation material.
Signal Connections:
To preserve RF screening integrity the signal connections to the power unit should be made using good quality
coaxial cable and connectors.
•
The use of cable benchmarked under the CAI scheme is recommended.
•
The use of crimp F connectors, used in accordance with the manufacturers instructions will give the best
results. The importance of achieving sound braid connections cannot be over-stressed. F connectors
should be tightened with a spanner, not left finger-tight.
