4 GPS 152H Installation Instructions
To install the GPS 152H device on the mounting bracket:
1. Loosely attach the two mounting knobs to the sides of the GPS 152H device.
2. Insertthedeviceintothemountingbracket.Thebracketisdesignedforatightttoprovideadditionalsupportwhentiltingtheunit.
3. Adjust the angle of the device, and tighten the two mounting knobs until the device is snug.
Installing the GPS 152H Wiring Harness
The GPS 152H device comes with a wiring harness that
connects the device to power and to optional NMEA 0183
devices.
Notes:
Use an AGC/ 3AG - 1.5 A replacement fuse.
If it is necessary to extend the power and ground wires,
use 22 AWG wire.
You can wire the harness directly to the battery, or if
your boat has an electrical system, you might be able to
wire the harness to an unused holder on the fuse block.
If you use the boat fuse block, remove the in-line fuse
holder on the power wire of the harness..
notice
The maximum input voltage is 40 Vdc. Do not exceed this voltage because this can damage the device and void the warranty.
NOTE: During a typical installation, use only the red and black wires. The other wires do not have to be connected for normal operation of the
device. For information on connecting to a NMEA 0183 device, see below.
Connecting the Wiring Harness to Power
1. Use a test light or a voltmeter to determine the polarity of the voltage source.
2. Connect the red (+ or positive) wire to the positive voltage terminal. (If you use the
fuse block on the boat, route the positive connection through the fuse, as shown on the
diagram.)
3. Connect the black (- or ground) wire to the negative voltage terminal.
4. Install or check the 1.5 A fuse (in the in-line fuse holder, or on the fuse block of the boat).
Connecting the Wiring Harness to a NMEA 0183 Device
You can connect the GPS 152H device to other NMEA compatible equipment, such as a
DSC or AIS device. Refer to the wiring diagram for connecting the device to NMEA 0183-compatible devices.
