Follow these steps to connect power to the
antenna and ADCU.
a. Before you begin, disconnect vessel power.
b. Connect the power cable from the antenna to
12 VDC (4 amps continuous) vessel power
via a dedicated 10-amp circuit breaker (see
c. Connect an additional power cable from
12 VDC vessel power to the power (+) and
ground (-) terminals on the green ADCU
terminal strip connector, as shown in
Figure 28 (for cable specifications, see
d. Plug all of the terminal strip connectors into
the rear panel of the ADCU. Be sure to plug
them into their correct positions, as shown in
e. Using the supplied tie-wraps, strain-relieve
all wires at the ADCU. If a ferrite is installed
on the cable, position the ferrite as close as
possible to the terminal strip connections and
strain-relieve the wires next to the ferrite (see
Figure 30). Also be sure to allow just enough
slack in the cables for easy serviceability.
CAUTION
For your own safety, disconnect vessel power
and make sure the circuit is dead before you
connect any power wires.

Double-check all of your wiring before
continuing. If wiring is incomplete or
incorrect, electronics may become damaged
when you apply power.
