Vehicle 50-150VDC Power Connection

1. Please review the
2. The Thor VM3 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.
3. Route the cable from the Thor VM3 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.
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 or a single red wire) to the
output block. See
7. Connect the stripped end of the negative wires (black and black/white twisted together or a single black wire)
to the output. See
Note: The input and output blocks each have two + (plus), two –
(minus) and two
in the block can be used to connect the matching polarity
wire.
8. Route the wiring from the DC/DC power supply to the vehi-
cle's electrical system. Do not connect to vehicle power
at this time.
9. Strip the wire ends and connect to the input side of the DC/
DC power supply.
10. Use looms and wire ties to secure all wiring as shown.
11. Reattach the cover with the screws.
12. Connect the DC/DC power supply to the vehicle's electrical system as directed below
For battery powered vehicles:
+ is connected to battery positive.
- must be connected to battery negative.:
must be connected to the vehicle chassis ground.
For internal combustion engine powered vehicles:
+ is connected to battery positive.
- is connected to battery negative.
is connected to the vehicle chassis ground, which can also be battery negative.
13. While observing the
actual battery terminals of the vehicle. When available, always connect to unswitched terminals in the vehicle
fuse panel, after providing proper fusing.
ATTENTION: For uninterrupted power, electrical supply connections should not be made at any point
after the ignition switch of the vehicle.
14. Use proper electrical and mechanical fastening means for terminating the cable. Properly sized "crimp" type
electrical terminals are an accepted method of termination. Select electrical connectors sized for use with
18AWG (1mm
15. Provide mechanical support for the cable by securing it to the vehicle structure at approximately one foot inter-
vals, taking care not to over tighten and pinch conductors or penetrate the outer cable jacket.
16. Connect the watertight connector end of the power cable to the Thor VM3 Quick Mount Smart Dock power
connector by aligning the connector pins to the power connector; push down on the watertight connector and
twist it to fasten securely.Flip the power switch on the back of the dock to On.
