Auto-On Control Wiring Diagram
Auto-On power mode must be selected on 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
• Black wire must be connected to battery negative. If there is a black wire and a black/white wire, twist
• 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
• Black wire must be connected to battery negative. If there is a black wire and a black/white wire, twist
• 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. Use VM3055FUSE (or equivalent) to install the
fuse as shown below:
• For 12VDC input, use the 10A fuse from the kit or a slow blow fuse that has a DC voltage rating
• For 24VDC input, use the 6A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
• For 36VDC input, use the 4A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
• For 48VDC input, use the 3A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
Note: For North America, a UL Listed fuse is to be used.
