Fuse Requirements
• For all voltages , use the 3A fuse from the kit or a slow blow fuse that has a DC voltage
rating greater than the vehicle input voltage.
Note: For North America, a UL Listed fuse is to be used.
Power Cable Identification
The DC power cable is included with the dock:
Note: Correct electrical polarity is required for safe and proper installation. See Wiring Diagram
for additional wire color-coding specifics.
The Thor VM3 DC input wires (Red, Red/White DC+ and Black, Black/White DC-) and
the Blue ignition input wire are galvanically isolated. The Green ground input is used for
electrostatic discharge (ESD) protection.
Vehicle 50-150VDC Power Connection
1. Please review the Wiring Diagram , before beginning power cable install.
2. The Thor VM3 must not be mounted in the dock. The power switch on the dock must
be turned Off . The power cable must be UNPLUGGED from the dock.
3. Route the cable from the Thor VM3 to the DC/DC power supply. Route the power
cable the shortest way possible. The cable is rated for a maximum temperature of
105°C (221°F). When routing this cable, it should be protected from physical
damage and from surfaces that might exceed this temperature. Do not expose the
cable to chemicals or oil that may cause the wiring insulation to deteriorate. Always
route the cable so that it does not interfere with safe operation and maintenance of
the vehicle.
4. Cut the cable to length and strip the wire ends.
5. Remove the lid from the DC/DC power supply.
6. Connect the stripped end of the positive wires (red and red/white twisted together)
to the output block. See Power Cable Identification .
Warning: For proper and safe installation, the input power cable must be
connected to a fused circuit on the vehicle. 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:
