2.3.2 Connecting to Vessel Power
Recommended Power Wiring
Short circuits may result in severe electrical shock or burns. Turn
off vessel power and test the circuit to ensure that no power is
present before connecting the power cable.
The switchplate requires an 11-16 VDC power input. A quick-
tripping circuit breaker or fuse should be installed between the
switchplate and vessel power. Circuit overload protection should
be rated for 5 amperes. If vessel power fluctuates widely or is
noisy, a 12 VDC 5-amp AC/DC power supply or a wide-range
DC/DC converter power supply should be installed. Test the
voltage and polarity before making connections to vessel power.
Connecting the Power Cable to the Switchplate
1. Disconnect vessel power by removing the
appropriate vessel fuse.
2. Connect the switchplate to vessel power as
pictured in Figure 2-15.
Before connecting the antenna unit
to vessel power, remove the
appropriate vessel fuse to prevent a
short circuit.
