Terminal Connections: The VC-30 is supplied with a Delphi/Packard Metri-Pack 280 Series, 5-position
connector. The mating connector is Delphi/Packard P/N: 12186400.
The terminations are as follows:
A: +12V Output
B: Ground
C: +24V Input
D: Over Temperature (output is a switch closure to ground capable of sinking 100 ma, MAX, useable
for a dash light, etc.)
E: Ignition
Fusing: A fault protection device must be installed between the DC to DC Converter and the power source
(battery). A fault protection device would be any fuse or circuit breaker properly rated for the maximum DC
input current. This advisory is in accordance with SAE, NEC and UL, for mobile power applications.
Minimum Wire and Fuse Sizes: Connect Model VC-30 to the 24vdc source using 10AWG cable, and
protected by a 40-amp fuse or circuit breaker. Using the same size cable for all circuits is recommended.
Install adequate fuse protection if smaller cables are used.
Wire Temperature rating: Wire ratings should be at least 105ºC.
Mounting Location: The DC to DC Converter may be mounted in any orientation, however for optimum
cooling, mount the converter with fins vertical.
Environmental Protection: Protect the unit from direct exposure to moisture such as high-pressure washing,
rain, etc. The converter is water-resistant and therefore exposures to high-pressure washing less than 3 feet
should be avoided.
