Power Supply Receptacle
Figure 7-5 Power Supply Receptacle (Front View)
・
Mating Female Type Plug:
14–P3F
The power cable supplied is approx. 3 meters long and is of two–wire shielded type,
normally terminated in a 3–hole female type plug at one end, with 3 conductors
open–ended each at the other end. Exercise

below.
After pushing the plug into the above receptacle and tightening its coupling ring,
connect the three conductors as follows:
・
Black conductor: to negative ( – ) terminal of ship’s power source
・
White conductor:
to positive ( + ) terminal of ship’s power source (

< CAUTIONS >
1. The DC power cable specified for use with the F–2000 / F – 3 0 0 0 W o r
DEBEG 4620/DEBEG 4630 cannot be plugged into the above receptacle.
2. Reversing the power cable polar i t y (black and white connections) causes
the fuse to blow.

Cabinet Ground Terminal
Figure 7-6 Cabinet Ground Terminal
The receiver cabinet, which is electrostatically
coated inside, can be grounded to the vessel’s earth
ground without grounding the negative line of the
ship’s power source. In situations where it is
required, or desirable, to ground the cabinet for
safety reasons or

EMC compliance, connect from
this terminal to an appropriate earth ground in the
vessel using a thick wire. The ground wire should
be as short as possible to reduce the chance of
picking up interference from other onboard
electronics.
