CONNECTING THE POWER SUPPLY UNIT (PSU)
Calculate the total current consumption of the Multiswitch(es), LNB and
any Launch Amplifiers that make up the complete IRS System. The current
consumption of the Series D Multiswitch range can be found in the Specification
section of this manual. If in doubt, assume the current consumption 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 additional PSU(s) may be
connected to any other Multiswitch, Launch Amplifier, Tap or Splitter within
the system. When all connections have been made, connect the PSU to a
240V supply 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 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.
