Connecting the Subscriber Cables
Terminate the Subscriber Cables with good quality F Connectors and connect to the Subscriber
Outputs. The F Connectors should be fitted to the coaxial cable correctly, ensuring that the centre
core protrudes 3mm above the F Connector body.
See figure 3.
Ensure that you do not exceed the
bending radius of the Coaxial Cable being used. The Subscriber Cables may be arranged either
side of the Multiswitch before being terminated and connected. If required, the Subscriber Cables
may be arranged to one side of the Multiswitch, with the cables passing under the Multiswitch before
being terminated and connected to the Subscriber Outputs on the opposite side.
See figure 4.
Always use CAI approved high quality coaxial cable.
Connecting the Power Supply Unit (PSU)
The PSU must be fixed to the relevant wall surface using the appropriate fixings. Connect the DC F-
type lead to the 18V DC Input of the Multiswitch.
Once all connections have been made, connect the plug to a 240V socket to power up the
Multiswitch.
If a local mains supply is not available such as in lofts and outdoor cabinets, the Power
Supply Unit may be conveniently fitted elsewhere whereby the 18V DC F-Type lead may be extended
using coaxial cable.

Earth Bonding
Earth bond the Multiswitch to the Earth Bonding Lug using minimum 4mm² Earth Bonding Cable.
Make sure that the Earth Bonding Cable is connected directly to the building’s PME (Protective
Multiple Earthing) point.

CONNECTING THE POWER SUPPLY UNIT (PSU)
Calculate the total current consumpti on of the Series 5 Multi switch(es), LNB
and any Series 5 Launch Amplifi ers that make up the complete IRS System. The
current consumpti on of the Series 5 Multi switch range can be found in the
Specifi cati on secti on of this manual. If in doubt, assume the current consumpti on
of each LNB to be 200mA max (0.2A). Connect a suitable Whyte PSU to the
Auxiliary 18V DC Input. If more than one PSU is required, the additi onal PSU(s)
may be connected to any other Multi switch, Launch Amplifi er, Tap or Splitt er
within the system. When all connecti ons have been made, connect the PSU
to a 240V socket to power up the IRS System. It is highly advisable to isolate
and hence divide the system in to DC Groups containing only a single PSU per
group, by using F-type DC blockers (not supplied).

CONNECTING THE SUBSCRIBER CABLES
Terminate the Subscriber Cables with good quality F Connectors and connect to
the Subscriber Outputs. The F Connectors should be fi tt ed to the coaxial cable
correctly, ensuring that the centre core protrudes 3mm above the F Connector
body. See fi gure 3. Ensure that you do not exceed the bending radius of the
Coaxial Cable being used. The Subscriber Cables may be arranged either side
of the Multi switch before being terminated and connected. If required, the
Subscriber Cables may be arranged to one side of the Multi switch, with the

the Subscriber Outputs on the opposite side. See fi gure 4.
EARTH BONDING
Earth bond the Multi switch to the Earth Bonding Lug and/or the Earth Terminal
Bars using minimum 4mm² Earth Bonding Cable. It is best practi se to earth bond
across the Earth Bars of all components within a single IRS System using a single
unbroken Earth Bonding Wire. To achieve this, strip away 3cm of the insulati on
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.
