Installation notes
Installation fixed wiring plan
The fixed wiring for a full installation is shown in
Fig. 1
. Use of the IRS 2 and
CCTV inputs is optional; these can be left unconnected if the corresponding facilities
are not required. Any number of extension rooms may be connected, up to the
maximum of five.
starBOX location and fixing
Choose a suitable central location to fix the starBOX unit. The location must be
dry and not subject to prolonged ambient temperature conditions of less than
-10 °C or more than + 40 °C.
Fix the starBOX unit to a sound vertical surface such as a wall or equipment
mounting board. Ventilation gaps of at least 50 mm should be left around the
front and all sides of the unit. More clearance will be required above, below and
to the left of the unit to allow access for the signal cables.
Do not install the unit where it could become smothered with curtains or
other soft furnishing fabrics or leave it resting on a carpet. When installing
the unit in a roof space or similar building void ensure that it will not
come into contact with thermal insulation material.
Cables and signal connections
To preserve RF screening integrity the signal connections to the unit should be
made using good quality coaxial cable and connectors. This is particularly important
with digital terrestrial TV (DTT) to minimise the ingress of impulsive electrical
interference from home appliances, and with digital satellite TV to prevent missing
channels. The use of cable benchmarked under the CAI scheme is recommended.
All signal connections are made with Type-F connectors. The use of good quality
crimp connectors, used in accordance with the manufacturers instructions will
give the best results. The importance of achieving sound braid connections cannot
be over-stressed. Completed connections should always be tightened with a
spanner leaving them finger-tight can sometimes lead to poor connections and
attenuation of the signal.
If the CCTV input is not used, the 75
Ω
terminator plug supplied must be left in
place. Any other unused connectors may be left open.
Mains supply connection and safety notes
The starBOX is supplied with a fitted mains plug and may be plugged directly into
a 13 A (BS 1363) socket outlet. If socket outlets of a different type are in use,
please refer to the safety instructions on page 11. The mains plug should remain
readily accessible to permit disconnection of the unit from the supply.
Alternatively the plug may be cut off and the amplifier wired into a readily
accessible fused connection unit, fitted with an approved 3 A fuse to BS 1362.
This method of connection is recommended for permanent distribution system
applications, since it reduces the risk of tampering and accidental disconnection.

Notes
1. CCTV IN is an auxiliary UHF input and can be used for any UHF (modulated) signal source. This
input should always be terminated in 75
Ω
if not used (a suitable termination is supplied with
each unit).
2. Maximum UHF signal levels are is given for 5 analogue TV channels plus up to 6 DTT multiplexes
at
£
-14 dB relative level (FM radio signals should not exceed -10 dB relative to analogue TV).
