Installing Hardware
3. Prepare the cable termination: Strip 3/8”
of insulation from the two wire ends and
terminate them with a connector that
matches your vehicle’s requirements. See
the Installation Note, right, for more
information.
a. Connect the red wire to the vehicle
power source. Connect the black wire
to a vehicle ground wire or chassis
ground.
b. Connect the External DC power cable
to your vehicle power source.
4. Insert the terminal end of the External
DC power cable into the terminal’s Power
Connector. Align the red dot on the end
of the power cable with the red dot on the Power Connector.
W ARNING
A Lead Acid battery can leak Hydrogen gas. A spark anywhere
near the battery can cause it to explode. Always make your final
connection to power as far away from the battery as possible, i.e.,
connect the power cable to the battery first, then connect it to the
terminal.
Providing Power: Wall or Workbench Installations
For wall or workbench-mounted terminals, or for operating a terminal while away from a
vehicle, you can power an VRC 6940 from an AC universal power supply. You need the AC
universal power supply, an AC line cable, and a DC power cable as listed on
page 2-1 .
To provide power from an AC source:
1. Insert the AC line cable into the AC connector on the AC universal power supply.
2. Plug the other end of the AC line cable into an AC wall outlet.
3. Insert the DC power cable into the DC connector on the AC universal power supply.
4. Plug the other end of the cable into the terminal’s Power Connector.
Installation Note: Cable Termination
How the cable terminates depends on
your vehicle. If your vehicle has a power
output connector, then attach a mating
connector to the end of the power cable.
You may be able to connect to a fuse
panel with a commercially available
connector. If your vehicle has no power
output connector, attach a ring terminal
(for a battery post) or blade terminal
connector (for a fuse panel).
Consult your vehicle Owner’s Manual
for information on how to access your
vehicle’s power supply.
