Vehicle 12-80VDC Power Connection 39
E-EQ-VX3XOGWW-E VX3X User’s Guide
How To: Connect Vehicle 12-80VDC 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 battery terminals of the vehicle. When available, always
connect to unswitched terminals in vehicle fuse panel, after providing 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.

4. Provide mechanical support for the cable by securing it to the vehicle structure at
approximately one foot intervals, taking care not to over tighten and pinch conductors
or penetrate outer cable jacket.
5. Connect the power cable to the VX3X.
