Prepare the Customer's Power Cable
You will need to connect a power cable from the
antenna to the vessel's 100-240 VAC power
supply. The cable must be a marine-grade,
3-conductor, stranded (flexible, bend radius of at
least 3" (8 cm)) power cable suitable for carrying
500 watts AC power to the antenna with less than
a 5% voltage drop across its length. Refer to
Figure 18 for the suggested cable gauge for your
cable run.
IMPORTANT!
Be sure to comply with all applicable
electrical codes and safety standards for the
vessel's country of origin and vessel type.
Route the Cables Belowdecks
a. Keep the ends of the data, power, and RF
cables shown in Figure 19 at the antenna
location.
b. Route the opposite ends of the cables
belowdecks through the cable access hole.
Leave an adequate service loop,
approximately 8" (20 cm) of slack, in all of the
cables at the antenna location for easy
serviceability.
c. Route the cables to the belowdecks
equipment. Be sure to always maintain the
minimum bend radius in the RF cables (see
Figure 20). Later, you will connect the data
cable to the CommBox-ACU, the power cable
to the vessel's AC power supply, and the RF
cables to the modem.
WARNING
Do not connect the power cable to vessel AC
power yet. You will connect power in Step 12
on page 24.
