4 Vehicle Power Supply Installation Guide
Since the power supply will produce heat, it is advisable to mount
it on a minimum of 130-160 square inches (840 to 1030 square
centimeters) of metallic surface to disperse heat. This location
should not be in the vicinity of sources of vehicle-generated heat.
About the LEDs
A single or a pair of green light-emitting diodes (LEDs), located
near the output connectors on the power supply, will be lit
whenever voltage is supplied to the output power cable.
Mount the power supply in a location that allows easy visibility
to the LEDs for troubleshooting.
One LED indicates main power is functioning (3-pin connector).
The secondary power LED indicates the heater power (2-pin
connector) is functioning.
Power Supply (P/N 851-070-003) 6-60V, 14A
Power Supply (P/N 851-041-003) 15-96V, 4.5A
Note: Use the hardware supplied in the kit, or
equivalent, to mount the power supply. Do not use
sheet metal screws or other less permanent or rugged
mounting solutions.
Note: If the secondary LED is not lit, the input power
to the DC-DC converter is less than 9-10 volts. It will
continue to provide 12V output power to the main
power connector.
