Installation 2 - 9
Power On/Off with Ignition
The VC80 is equipped with an ignition sense feature which puts the terminal into suspend/shutdown when the
vehicle ignition is turned off and can power on the terminal when the ignition is switched on. To use this feature, a
power extension cable with ignition sense wires must be used and installed properly on the vehicle.
The cable in Figure 2-4 is the power extension cable (p/n CA1220) with two wires used to connect to vehicle igni-
tion. The red and black leads of the two 18AWG wires that connect to the key switch of the ignition and ground,
respectively. Once the wires are connected, the VC80 may switch on or off depending on the state of the vehicle
ignition key. See Power for VC80 Windows 7 on page 3-20 to select power settings.

IMPORTANT
When connecting to an ignition switch using the power extension cable with ignition sense
wires, ensure that the wires of different polarities are reliably secured away from each
other, or are separated with reliably secured certified insulation. A minimum distance of
2.8mm (or 0.4mm distance through insulation) is required for the separation.
The thinner wires (18 AWG) are used for Ignition Sense wires while the thicker wires
(14AWG) are used for Vehicle Power and Ground. Identify them carefully and
Do Not confuse them.
An appropriate fuse type must be used with the power extension cable according to the
installation instructions. For the main power cable, use 3AB, 15A, 250V, slow blow fuse.
For ignition sense input, use 3AB, 0.3A, 250V, slow blow fuse.
