Raymarine G170 Instructions

Please read and follow the instructions on this sheet when installing your Raymarine Sunlight Viewable Display.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN DAMAGE TO YOUR EQUIPMENT/BOAT AND COULD
Grounding the display
CAUTION
Grounding the display
An effective radio frequency (RF) and safety
ground must be connected to the display. You
must ground the display by connecting the drain
wire (shield) of the power input cable to the
nearest ground point of your boat's RF ground
system. This ground should not be connected to
the boat's battery or at any point other than the
boat's RF ground connection.
The power connection to the display should be made at either
the output of the battery isolator switch, or at a DC power distri-
bution panel. Raymarine recommends that power is fed directly
to the display via its own dedicated cable system and MUST be
protected by a thermal circuit breaker or fuse, fitted close to the
power connection. If you do not have a thermal circuit breaker or
fuse in your power circuit, you MUST fit an in-line breaker or
fuse to the positive red line on the power lead.
Refer to the following table for isolator switch circuit breaker or
fuse value ratings and check all terminal connections are clean.

Extending the power cable

Longer power cable runs may require larger wire gauges to mini-
mize 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 the free end to the extension cable; take partic-
ular care to ensure correct polarity and grounding of the drain
wire (shield) to the boat's RF system. The supplied power cable
has a cross section of 12 AWG (3.3 mm
