Raymarine Radar Scanner manual Cable runs, Rejoining Cables

Chapter 1: Overview 11

1.4 Cable runs

You need to consider the following before installing the system cables:

•You need to fit the inter-unit cable and the power cable.

•All cables should be adequately clamped and protected from physical damage and exposure to heat - avoid running cables through bilges or doorways, or close to moving or hot objects.

•Acute bends must be avoided.

•Where a cable passes through an exposed bulkhead or deckhead, a watertight gland or swan neck tube should be used.

•Avoid cutting and re-joining cables (if necessary, refer to the notes below).

You need to run the following cables:

CAUTION:

Do not pull the cable through bulkheads using a cord attached to the connector. This could damage the connections.

•Inter-unit cable. A vinyl-covered and shielded cable is supplied with the radome scanner unit. The cable has a connector plug at one end for connecting to the display unit or extension cable; the other end of the radome scanner cable is fitted with an 8-way plug and power cores (covered by a clear protective sleeve) for con- necting to the scanner.

For open array scanners, various length cables are available. These cables have a connector plug at one end for connecting to the display unit or extension cable; the other end is prepared ready to fit to the power and signal connectors (see Section 2.2)

•Power cable. The scanner receives power via the display unit; the power cable is supplied with the display unit. However, cable details are provided in this section.

Rejoining Cables

You should avoid cutting and re-joining cables. If this is necessary you must:

•Fit a ferrite on each side of the join. The specific ferrite to use depends on the cable type - contact Raytheon Marine for details.

•Take care not to damage any of the wires. Make sure that all the wires and, in particular, the screen are reconnected correctly.
