Connect Power

Follow these steps to connect power to the MCU.

The MCU supplies power to the antenna.

a. Before you begin, disconnect vessel power.

CAUTION

For your own safety, disconnect vessel power and make sure the circuit is dead before you connect any power wires.

b. Connect a power cable to 24 VDC (2.5 amps) vessel power (for cable specifications, see

Figure 2 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 to help reduce conducted emissions. Make two loops in the cable and clamp the coil around the loops

(see Figure 20). This ferrite coil must be

installed to comply with the CE standard.

e. Find the plastic power plug supplied in the

kitpack (see Figure 21). 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 power connector plug into the

“Power In” jack on the MCU. Secure in place with the two retaining screws.

g. Connect the MCU ground wire (see

Figure 22) to a suitable ground point.
