MATERIALS PROVIDED
Your NAV-PAC comes with the following materials:
(3) # 8 ring lugs for 22-16 gauge wire
(4) # 8 ring lugs for 12-10 gauge wire
(3) butt connectors
(1) Installation/Operation Manual
Check to see that these have been included with the packaging. For any missing
items, please contact the factory.
INSTALLATION
1
)
After you have determined the best location in the system, locate a flat
surface close to the power line that feeds the GPS, SAT-NAV or plotter. For
best results the NAV-PAC unit should be within 24" of the critical electronics.
The case need not be grounded, so it is acceptable to mount the unit on wood
or metal. Securely mount the NAV-PAC.
Turn off power to the wires that will be cut or worked on by disconnecting the
battery or shutting off the appropriate circuit. Identify the positive and
negative lead in the power line and cut at an appropriate location. Use the
lugs supplied to hook up the NAV-PAC to your system.

Current draw of NAV equipment being powered.
Replace terminal block cover to prevent accidental shorting of the terminals.
Imporant Installation Note: If there is to be a continuous load on the Nav-Pac
output during normal operation, the DC input must be a minimum of 13.4 VDC to
prevent discharge of the internal battery.
3)
Remote Panel: Mount in a conspicuous location where the loss of power
indication will be noticed. The NAV-PAC will function normally without the
remote panel or with the remote panel switch off. Connect the wiring as
follows: (see diagram)
OPERATION
When the remote status panel is properly hooked up and DC power is being
applied to the NAV-PAC, both the “INPUT OK” and “OUTPUT OK” LED’s will
steadily illuminate. This indicates that pure DC power is available at the output
terminals and that the internal 5.0 amp-hour battery is being kept charged. (The
LED lights draw only about .01 amp each.)
In the event of a loss of DC input to the NAV-PAC, the “INPUT OK” LED will be
extinguished and the “OUTPUT OK” LED will begin to flash. This indicates that the
navigation equipment is being powered by the NAV-PAC’s internal battery only.
It will also indicate that the timed battery disconnect circuit has been initiated. After
approximately 15 minutes the NAV-PAC’s internal battery will automatically
disconnect from the NAV-PAC’s output. This is to protect the battery discharge if
TYPICAL INSTALLATION DIAGRAM
NOTE: Remove both fuses before wiring the NAV-PAC. Reinstall fuses only after
carefully checking installation and wiring.
