SECTION TWO: Installing and wiring the 957
Page 16 957 Installation Manual, Revision C1
The power cable has an inline fuse to protect the vessel’s
wiring, prevent electrical fires, and prevent damage to the 957.
If you shorten this cable, be sure to keep the inline fuse intact.
The wires in the power cable must be connected as follows.
•
red → positive(+)
•
black → negative(–)
•
green → ship’s ground
NOTE:
Ground the 957 to the vessel to eliminate
interference. Without an earth grounding,
performance may be reduced. Secure the green
wire to the vessel’s nearest grounding point. If a
noise-free earth grounding point isn’t available, cap
and insulate the green wire—it shouldn’t be used
when an earth ground isn’t available, or with
systems using “floating” grounds.
