Power Cable Identification

The DC power cable (included with the dock) is one of the two styles below:

Power cable with right angle connector and 6 wires:

!Twist the red and red/white wires together and twist the black and black/white wires together before connecting to vehicle power.

Power cable with straight connector and 4 wires:

Note: Correct electrical polarity is required for safe and proper installation. See Wiring Diagram (page 4-42)for additional wire color-coding specifics.

The Thor VM2 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 4-42),before beginning power cable install. The Thor VM2must be powered off and the power cable disconnected from the Thor VM2. The last connection must be to the vehicle power source before connecting the power cable to the Thor VM2.

1.Route the cable from the Thor VM2 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 4-40).

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 4-40).

Note: The input block has VIN+, VIN- and GND terminals. The output block has VO+ and VO- terminals.
