Auto-On Control Wiring Diagram
Auto-On must be selected on the AutoOn (page 5-5) control panel. The vehicle supply connections should
be made to vehicle switched power to allow the terminal to automatically power-up when vehicle power is
switched on or when the power switch on the back of the dock is placed in the On position. The Ignition wire
is not used and should be left disconnected.
.
CAUTION
For battery powered vehicles:
Red wire is connected to battery positive. If there is a red wire and a red/white wire, twist them
together and connect to battery positive.
Black wire must be connected to battery negative. If there is a black wire and a black/white wire, twist
them together and connect to battery negative..
Green wire must be connected to the vehicle chassis ground.
For internal combustion engine powered vehicles:
Red wire is connected to battery positive. If there is a red wire and a red/white wire, twist them
together and connect to battery positive.
Black wire is connected to battery negative. If there is a black wire and a black/white wire, twist them
together and connect to battery negative.
Green wire is connected to the vehicle chassis ground, which can also be battery negative.
WARNING
For proper and safe installation, the input power cable must be connected to a fused circuit on the ve-
hicle. 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’s positive (+) terminal. The fused circuit requires a maximum time
delay (slow blow) fuse with a current rating as noted below.
•For 12VDC input, use a 10A slow blow fuse that has a DC voltage rating greater than 12VDC.
•For 24VDC input, use a 6A slow blow fuse that has a DC voltage rating greater than 24VDC.
•For 36VDC input, use a 4A slow blow fuse that has a DC voltage rating greater than 36VDC.
•For 48VDC input, use a 3A slow blow fuse that has a DC voltage rating greater than 48VDC.
Note: For North America, a UL Listed fuse is to be used.
