Vehicle 12-80VDC Power Connection

Caution:

For proper and safe installation, the input power cable must be connected to a fused circuit on the

vehicle. This fused circuit requires a 10 Amp maximum time delay (slow blow) high interrupting rating

fuse. If the supply connection is made directly to the battery, the fuse should be installed in the positive

lead within 5 inches of the battery positive (+) terminal.

Caution:

For installation by trained service personnel only.

Warning:

Risk of ignition or explosion. Explosive gas mixture may be vented from battery. Work only in well

ventilated area. Avoid creating arcs and sparks at battery terminals.

Note: Please see “Power Adapter Cable” later in this section for information on adapting a

VX1, VX2 or VX4 DC power supply to the VX7.

Note: Correct electrical polarity is required for safe and proper installation. Connecting the

cable to the VX7 with the polarity reversed will cause the VX7’s fuse to be blown. See
the following figure titled “Vehicle Connection Wiring Color Codes” for additional wire
color-coding specifics.

How To: Connect Vehicle 12-80VDC Connection

1. The VX7 must be turned off and the power cable must be UNPLUGGED from the VX7.
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.
