Power Cable Identification
The DC power cable (included with the dock) is one of the two styles below:
Note: Correct electrical polarity is required for safe and proper installation. See Wiring Diagram (page 4-41) for
additional wire color-coding specifics.
The Thor VM1 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
Please review the Wiring Diagram (page 4-41), before beginning power cable install. The Thor VM1must be pow-
ered off and the power cable disconnected from the Thor VM1. The last connection must be to the vehicle power
source before connecting the power cable to the Thor VM1.
1. Route the cable from the Thor VM1 to the DC/DC power supply. Route the power cable the shortest way pos-
sible. 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.
2. Cut the cable to length and strip the wire ends.
3. Remove the lid from the DC/DC power supply.
4. Connect the stripped end of the positive wires (red and red/white twisted together or a single red wire) to the
output block. See Power Cable Identification (page 4-39).
5. Connect the stripped end of the negative wires (black and black/white twisted together or a single black wire)
to the output. See Power Cable Identification (page 4-39).
Note: The input and output blocks each have two + (plus), two –
(minus) and two (ground) connectors. Either connector
in the block can be used to connect the matching polarity
wire.
