POWER
The GlobalNav 310 will operate from a 12-volt DC system. (9 to 15 volts
DC.) You can connect the power cable to an accessory buss under the
dash, however, to keep electrical noise interference to a minimum, we
recommend you wire the power cable directly to the battery through the
supplied 2-amp fuse.
CAUTION!
Do not connect this product to a power source without using a fuse!
Failure to use the fuse can cause damage to your unit and will void the
warranty.
Follow the wiring diagram below. If the wires on the power cable are not
long enough to reach the battery, use 18 gauge wire to lengthen the
power cable.
The power cable’s green wire is used to receive data from a DGPS re-
ceiver. The white wire is used to transmit data to a DGPS receiver or
other electronic equipment. If you are not connecting the GlobalNav 310
to another device, tape the ends of these wires and secure them where
they will not short to one another. See the NMEA/DGPS section in this
manual for more information.
(Note: If your power cable has six wires, tape and secure the extra wires,
also. They are not used on this product.)
