IRS Multiswitch:
• The BLACOM31T allows you to distribute FM & DAB through an IRS system.
• It allows you to filter 5G & 4G interference in an IRS system.
Fixing:
The unit may be fixed to a mast using the cable tie supplied or screwed to a wall or other flat surface through the
two fixing holes provided in the rear part of the moulded cover. The cable tie fixing is intended to support the
weight of the combiner/splitter only; cables should be taped to the mast at intervals of approximately 400mm to
ensure that their weight is adequately supported. For indoor use the diecast module can be unclipped and
mounted directly if desired. Do not leave a unit supported only by its cabling.
Signal Connections:
To preserve RF screening integrity the signal connections to the power 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.
• 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 (but not over tight).
System equipotential bonding:
Bonding (earth) terminals are provided on the casting for use where BS EN 60728-11 compliance is necessary.
