How To: Connect Vehicle 12-80 VDC Connection
1. The VX3X must be turned off and the power cable must be UNPLUGGED from the VX3X.
2. While observing the fuse requirements specified above, connect the power cable as close as possible to the actual bat-
tery terminals of the vehicle. When available, always connect to unswitched terminals in vehicle fuse panel, after pro-
viding proper fusing.
ATTENTION:For uninterrupted power, electrical supply connections should not be made at any point after
the ignition switch of the vehicle.
3. Route the power cable the shortest way possible. The cable is rated for a maximum temperature of 75°C (167°F). When
routing this cable it should be protected from physical damage and from surfaces that might exceed this temperature.
Do not expose the cable to chemicals or oil that may cause the wiring insulation to deteriorate.
Note: If the vehicle is equipped with a panel containing Silicon Controller Rectifiers (SCR’s), avoid routing the
power cable in close proximity to these devices.
Always route the cable so that it does not interfere with safe operation and maintenance of the vehicle.
Use proper electrical and mechanical fastening means for terminating the cable. Properly sized “crimp” type electrical
terminals are an accepted method of termination. Please select electrical connectors sized for use with 22AWG (1mm
2
)
conductors.
