How To: Connect Vehicle 12-60VDC Direct Connection
VX4 User's Guide
1.
The VX4 must be turned off.
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 cable the shortest way possible. The input cable from the connection to
the battery is rated for a maximum temperature of 105°C (221°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 18AWG
2
(1mm
) conductors.
