Ignition Control Wiring Diagram
Ignition wire must be connected and the Ignition Control power mode must be selected via the
Configuration Mode (page 5-83) control panel. When switched vehicle power is available the Thor VM2 igni-
tion signal wire can be connected (less than 1mA over input voltage range) to the switched circuit to allow the
Thor VM2 to power on when the vehicle is switched on. When the vehicle is switched off, more aggressive
power management settings are enabled to preserve the vehicle battery charge.

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 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 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
greater than 12VDC.
• For 24VDC input, use the 6A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
than 24VDC.
• For 36VDC input, use the 4A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
than 36VDC.
• For 48VDC input, use the 3A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
than 48VDC.
Note: For North America, a UL Listed fuse is to be used.
