Raymarine M1500 manual Cable Runs, Audio/Video Junction Box optional accessory E85003

Extending the Power Cable

Longer power cable runs may require larger wire gauges to minimize any voltage drop in the cable. Ensure that the minimum voltage specification of the display is met at the junction of these cables when the display is operating at full brightness.

If a longer power cable run is required, use the supplied power cable to connect to the display unit. Then use a suitable connector block to connect the free end to the extension cable; take particular care to ensure correct polarity and grounding of the screening braid to the ship’s RF ground.

The supplied power cable has a cross-section of 12 AWG (3.3 mm2).

Cable Runs

You need to attach the cables shown in the illustration Connections - Typical Installations on page 14. Consider the following before installing the display:

•All cables should be adequately secured, protected from physical damage and protected from exposure to heat. Avoid running cables through bilges or door- ways, or close to moving or hot objects.

•Acute bends must be avoided.

•Where a cable passes through an exposed bulkhead or deckhead, a watertight feed-through should be used.

•Secure cables in place using tie-wraps or lacing twine. Coil any extra cable and tie it out of the way.

CAUTION:

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

Audio/Video Junction Box (optional accessory E85003)

Composite video or S-video inputs must be connected via the optional audio/ video junction box; the junction box can also be used for audio input only.

The audio input cable between the junction box and PC is 1m in length and must not be extended, so the audio/video junction box should be mounted adjacent to your PC. Connection details are provided with the audio/video junction box.

Display Location and Mounting Options

The display can be console mounted using the flush-mounting kit supplied. Alternatively, a bracket mount option (E05011) is available. The following section provides the display dimensions and console mounting instructions.

Raymarine recommend that you power the unit and select a suitable mounting location prior to installing the display. When planning the display location, the following should be considered to ensure safe, comfortable and reliable operation:

•Convenience: The mounting location should be easily accessible to allow operation of the front panel controls and should enable easy viewing of the dis- play.
