Thor VM3 with Microsoft Windows Embedded Compact 7 User Guide 77
Vehicle 10-60VDC Direct Power Connection
1. 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.
2. While observing the Fuse Requirements, connect the power cable as close as
possible to the actual battery terminals of the vehicle (if using unswitched power).
3. 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.
4. Refer to the wiring diagrams following this section for wire colors and connections:
• Ignition Control Wiring Diagram
• Auto-On Control Wiring Diagram
• Manual Control Wiring Diagram
5. Route the power cable the shortest way possible removing any left-over cable. The
cable is rated for a maximum temperature of 105°C (221°F). Therefore, when
routing this cable it should be protected from physical damage and from surfaces
that might exceed this temperature. Cable should be protected from physical
damage from moving parts. 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.
6. Provide mechanical support for the cable by securing it to the vehicle structure at
approximately one foot intervals, taking care not to over tighten and pinch
conductors or penetrate outer cable jacket.
7. Connect the watertight connector end of the power cable to the Thor VM3 dock
power connector by aligning the connector pins to the power connector; push down
on the watertight connector and twist it to fasten securely.
8. Secure the power cable to the Thor VM3 using the Strain Relief Cable Clamps.
9. Place Thor VM3 in the Dock
10. If using the Screen Blanking feature, install the screen blanking box or switch.
11. Press the Power Switch on the back of the Thor VM3 dock.
12. Press the Power Button on the front of the Thor VM3 to turn on the Thor VM3.
