Connecting DC Power
Your unit is intended for use on vessels with 12 VDC power systems and it
can operate as long as the DC supply is maintained between 10.2 and 16.0 VDC.
The supplied 6.5 foot power cable assembly should reach the source of DC
power.
On larger boats, route the power leads to the ships DC power distribution
panel. Connect to 10 amp or 10 amp (maximum) circuit breaker, as the unit is
fused at 10 amps.
On smaller vessels connect the power leads directly to the main battery
isolation switch or breaker.
Avoid grouping the unit’s power connections with radar, radio, or Loran-C
power leads on the same circuit breaker. Separate the wiring as much as possible
from other devices to prevent electrical noise interference.
Although the unit’s power consumption is approx. 50 watts, if you need to
extend the power cable leads by more than 10 feet, increase the wire size of the
leads accordingly to minimize line losses. For runs of 20-35 feet, #10 AWG is
recommended.
Connect the RED wire to the positive (+) source terminal as shown in Figure
2-8.
Connect the BLACK wire to the negative (-) source terminal as shown in
Figure 2-8.
If the power leads are accidentally reversed, the in-line fuse will blow. If this
happens, recheck the polarity of the connections with a volt-meter (VOM) and, if
necessary, reverse the leads for proper connection.
Then, replace the fuse.
If the unit will not turn on and you suspect that you may have reversed the
power connections, check the DC power lines all the way back to the battery. If
the polarity is not correct, properly reconnect the leads and try again.
RED to the positive.
BLACK to the negative.
Do not mistake the colors, as doing so will cause a
malfunction.
CAUTION
Do not touch the ground terminal and vessel ground
on the display unit at the same time without the
ground terminal earthed. Otherwise, you may suffer
an electric shock.
