Follow these steps to connect power to the MCU.
The MCU supplies power to the antenna.
a. Before you begin, disconnect vessel power.
b. Connect a power cable to 24 VDC (2.5 amps
continuous) vessel power (for power cable
specifications, see
Figure 3 on page 3 ). Power
supplied to the antenna MUST NOT fall
below 18 VDC or exceed 30 VDC.
NOTE: If a 24 VDC power supply is not available,
install an AC/DC converter that supplies 24 VDC
(KVH part #19-0488 or equivalent).
c. KVH recommends you install a 15-amp
circuit breaker between power and the MCU.
The MCU does not have an on/off switch.
d. Install the ferrite coil, supplied in the kitpack,
onto your vessel power cable (close to the
MCU) to help reduce conducted emissions.
Make two loops in the cable and clamp the
coil around the loops (see Figure 21 ). This
ferrite coil must be installed to comply with
the CE standard.
e. Find the plastic power plug supplied in the
kitpack (see Figure 22 ). Insert your vessel
power wires into the plug’s power (+) and
ground (-) terminals. Tighten the plug’s
terminal screws to secure the wires in place.
f. Plug the plastic power plug into the “Power
In” jack on the MCU (see Figure 23 ). Secure in
place with the two retaining screws.
CAUTION
For your own safety, disconnect vessel power
and make sure the circuit is dead before you
connect any power wires.
