Connection
Red
DC + output from DC/DC Power Supply
Black
DC - output from DC/DC Power Supply
Green
Ground output from DC/DC Power Supply
Blue
Ignition Input (not connected)
Note:
Correct electrical polarity is required for safe and proper installation. See the figure below for additional wire color-
coding specifics.
The Thor VM2C DC input wires (Red DC+ and Black DC-) and the Blue ignition input wire are galvanically isolated. The Green
ground input is used for electrostatic discharge (ESD) protection.
Connect Vehicle 72-144VDC
1. The Thor VM2C must not be mounted in the Quick Mount Smart Dock. The power switch on the Dock must be turned
Off
. The power cable must be UNPLUGGED from the Dock.
2. While observing the fuse requirements specified above, connect the power cable as close as possible to the actual
battery terminals of the vehicle.
3. Wiring installation:
l
The user must supply wiring from the vehicle to the DC/DC power supply.
l
Use proper electrical and mechanical fastening means for terminating the cable. Properly sized “crimp” type
electrical terminals are an accepted method of termination. Please select electrical connectors sized for use with
20AWG (0.81mm2) conductors.
l
Remove the lid from the DC to DC converter. Attach the stripped wire ends to the output side of the DC to DC
converter. Attach stripped wire ends to the input side of the DC to DC converter.
l
The input and output blocks each have two + and two – minus connectors. Either connector in the block can be
used to connect the matching polarity wire.
l
Use the looms and wire ties to secure all wiring then reattach the cover with the screws.
l
Connect as shown in
4. Route the power cable:
l
Route the power cable the shortest way possible removing any left-over cable
l
The cable is rated for a maximum temperature of 105°C (221°F). Therefore, routing this cable it should be protected
from physical damage and from surfaces that might exceed this temperature.
l
Cable should be protected from physical damage from moving parts
l
Do not expose the cable to chemicals or oil that may cause the wiring insulation to deteriorate
