Chapter 2 — Installation Process
18 Vehicle Power Supply Installation Guide
• Secure the cables at least every 18 inches (46 cm) throughout
the cable run. Use adjustable clamps (see the last page in this
chapter) or wire-tie to existing vehicle cable runs
Power Cable Connections
The fuse holder from the input power cable must be connected as
close as possible, both physically and electrically, to the positive
side of the vehicle power source. The remaining colored wires
must be connected to the negative side of the vehicle power
source.
Instructions are not included for connecting to various possible
vehicle power sources. It is assumed that a trained professional
installer, knowledgeable on the brands and models of vehicles he
or she is working with, will do the installation. Both large (3/8
inch) and smaller terminal rings are provided to accommodate
most installation needs.
Warning: If this installation will be on a gas-
powered vehicle, you must install either an On/Off
switch (minimum 15A DC rating such as ITW P/N
163-900-034) or an automatic shut-off device in
series with the in-line fuse holder.
These devices prevent discharge of the vehicle
battery while the lift is off.
Charge Guard, Inc. 400 Highland Avenue, Altoona,
PA 16602 (814.941.4100) manufactures a
CHARGE GUARD™ device for this purpose.
Note: In this installation, the shield wire must be
connected to the metal surface on which the power
supply is mounted. Prior to connecting power -
recheck to make sure the fuse is connected to the
positive connection on the DC/DC input, and that
the negative lead connects to the return to the battery
at a location not shared with motors, flyback diodes,
or other sources of electrical noise.
