VRC 6940 Terminal
WARNING
A Lead Acid battery can leak Hydrogen gas. A spark any-
where 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 bench-mounted terminals, or for operating a terminal
while away from a vehicle, you can operate 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
9.
To provide power from an AC source:
1. Insert the AC line cable into the AC connector on the AC uni-
versal 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 and the Internal Battery
A terminal’s internal battery may be depleted when you first install
it. The internal battery charges itself from the terminal’s main
power supply (DC or AC).
If the main power supply is stable, you can plug in the terminal and
use it immediately. If the main power supply is not stable, there
may be power interruptions that cause the terminal to reset itself
during its first few hours of operation.
If the terminal resets itself, you may lose unsaved data. To avoid
this, we recommend that you plug in the terminal and allow it to
charge for two hours before using it.
