2.6 Running the Cable

Introduction

A cable is required to supply power for operating the unit, charging its
batteries and providing NMEA connection on board your vessel. Of
course you can also charge the unit with the Cigarette Lighter Adapter.
Notes: (1) Adequately secure the Power/NMEA cable and protect from
POWER/NMEA Connector
CAUTION:
If you do not have a breaker in your power circuit, you must fit an in-
line 1A quick-blow fuse to the positive (red) lead of the power cable.
This unit is not intended for use on positive ground vessels.
The POWER/NMEA connector provides for 12VDC power connection
and NMEA inputs/outputs using the supplied cable.
The chartplotter is intended for use on vessel's DC power systems
operating in the range 10.0VDC to 18.0VDC (in other words, 12V
systems, not 24V or 32V systems).
Power connections should be made at a DC power distribution panel
through an isolator switch and a 1A circuit breaker or 1A quick blow fuse.
All connections must be clean and tight.
The DC power system should be either:
•
•
A 1.5m (5ft) power cable is supplied. If a longer power cable run is
required, use the supplied power cable to connect to the unit plus a
suitable connector block to connect to the extension cable. The supplied
power cable cores have a cross-section of 2.0mm
Longer power cable runs may require larger wire gauges to minimize any
voltage drop in the cable.
physical damage. Avoid running cable through bilges, doorways
or close to moving objects or heat sources.
(2) Where a cable passes through an exposed bulkhead or deck-
head, a swan neck tube should be used.
(3) Where the cable will be exposed to the elements, a suitable
drip loop should be used.
