Installation Instructions

The interface box requires 10-16 VDC power

input supporting 50 watts (4.2 amps @ 12 VDC).

Follow these steps to connect power to the

interface box.

a. Before you connect the power wires, turn off

vessel power and test the circuit to ensure no

power is present.

b. Connect the individual power wires to a

dedicated 10-amp or 15-amp circuit breaker.

Connect the negative (black) wire to ground

(power return), and connect the positive (red)

wire to +12 VDC vessel power.

NOTE: As an alternative, you may use an AC/DC

power supply (KVH part #72-0206-01) to supply

power to the interface box.

c. Plug the other end of the wires into the

“Power” jack on the rear panel of the

interface box (see Figure 18).

NOTE: Do not remove the small ferrite coil that is

clamped onto the power wires. This coil suppresses

EMI (electromagnetic interference) from the interface

box.

d. Connect power to the receiver. Follow the

instructions in the receiver’s manual.

CAUTION

For your own safety, disconnect vessel

power and make sure the circuit is dead

before you connect any power wires.
