IN STALLING THE RIU
11
Refer to Figure 1e and mount the Radar Interswitch
Unit (RIU) in its required location, ensuring sufficient
clearance for ventilation, cable access and servicing, as
follows:
(1) Mark out the position of the RIU and drill holes in
the required positions for mounting.
(2) Secure the RIU in position, using suitable bolts.
Earthing
12
Ensure that the RIU is earthed correctly, to the ship's
earth, using the earthing bolt provided.
ELEC TRI CAL CON NEC TIONS
Ca ble Screens
13
The cable screens are not to be stripped back further
than is necessary to enable the cores to be connected.
All exposed screens must be covered with PVC sleeving to
prevent accidental contact with live terminals.
Ac cess for Ca bling
14
Access to the RIU Processor PCB and the Video Sync
Switching Board is obtained by removing the RIU Front
Panel. Cables are fed through cable clamps fitted to the base
of the casing. Refer to Figure 2e for unit Locations.
NOTE:
Access to the inside of the RIU is via the front panel, which
is secured in position by six screws.
Ca ble In stal la tion
15
Refer to the appropriate interconnections diagram and
connect the cables between the RIU and the Nucleus 3
display and between the RIU and the Transmitter, or TIU (as
appropriate).
(1) Feed the Transmitter and Display cables through
the base of the unit and connect to the appropriate
input/output connectors.
16
Secure the cables in position, using the cable clamps
provided at the base of the unit.
17
Instructions for setting to work are provided in the
section on Commissioning, later in this chapter.
