INSTALLATION INSTRUCTIONS
MOUNTING THE MULTISWITCH
Select a suitable location to install the Multiswitch. Do not install the Multiswitch
in damp, humid, hot or dusty areas. Using the screw slots on the Corner Brackets,
secure the Multiswitch using the appropriate fixing screws and wall plugs to suit
the relevant wall surface or cabinet.
CONNECTING THE SAT & TERR INPUT AND OUTPUT TRUNK CABLES:
Use a suitably sized Satellite Dish to provide adequate signal levels from the
satellite being received. Ensure that the Satellite Drop Cables are connected
correctly to the LNB's. Ensure that the F Connectors are properly sealed against
water ingress. If a Composite Cable (multi core coaxial cable) has been used,
ensure that the outer jacket is not facing upwards and cannot collect rain water.
Check the Terrestrial Drop Cable and ensure that this has also been sealed
against water ingress. If a Triplexer has been used to combine FM and DAB
aerials with the UHF Terrestrial Aerial, ensure that this is also water tight. Ensure
that all drop cables have drip loops prior to their entering the building.
Connect the SAT and TERR drop cables to the corresponding Satellite and TERR
Inputs on the Multiswitch. Connect any additional Multiswitches or Trunk Cables
to the Satellite & TERR Trunk Outputs as applies. Ensure that you terminate the
last Multiswitch in a cascade using 75Ω DC Blocked F-type Terminators.

EARTH BONDING
Earth bond the Multiswitch to the Earth Bonding Lug and/or the Earth Terminal
Bars using minimum 4mm² Earth Bonding Cable. It is best practise to earth bond
across all Multiswitches using a single unbroken Earth Bonding Wire. To achieve
this, strip away 3cm of the insulation of a length of 4mm² Earth Bonding Wire.
See Figure 1.
Unscrew the Earth Bolt on the Earth Terminal Bar to provide enough clearance
to wrap the Earth Bonding Wire around the Earth Bolt.
See Figure 2.
Tighten the Earth Bolt and route the Earth Bonding Wire to all other Earth
Terminal Bars and terminate as detailed above. Make sure that the Earth Bonding
Cable is connected directly to the building’s PME.
