DC-to-DC Power Supply Installation Instructions
For use with the models listed below. These models can be identified by a lid with screws on the top of the lid. These models listed
below may be obsolete.
These models may be used to replace the obsolete power supplies. Contact Honeywell Technical Support or go to
www.honeywellaidc.com for DC/DC power supply installation instructions for the replacement models listed below.
Connecting electrical cables to power sources
The DC-to-DC power supply is used to power certain vehicle-mount computers (VMCs) or to provide vehicle power to certain hand-held
computers (HHCs) when placed in a DC powered vehicle dock or cradle.
Please refer to the appropriate wiring schematic on the following pages for wiring colors and connections:

Specifications for electrical supply
Input Voltage Always observe input voltage range specified on the DC-to-DC power supply and the optional screen blanking box
(for vehicle mounted terminals only).
Output Voltage 12 VDC ± 10%
Power 75 W
Fuse
Tecton, MX9, MX3 Plus, MX7: Use a 5 A slow blow fuse.
Thor VX8, Thor VX9, Marathon: Use a 10 A slow blow fuse
Thor VM1, Thor VM2, Thor VM3: Use VM3055FUSE (or equivalent) to install the fuse as shown below:
•For12VDC input, use the 10A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 12VDC.
•For24VDC input, use the 6A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 24VDC.
•For36VDC input, use the 4A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 36VDC.
•For48VDC input, use the 3A fuse from the kit or a slow blow fuse that has a DC voltage rating greater than 48VDC.
Screen Blanking Box: Use a 3 A fuse
Caution: For proper and safe installation, the input power cable must be connected to a fused circuit on the vehicle. This fused
circuit requires a user supplied 5 or 10 Amp maximum time delay (slow blow, see table above for fuse rating) high
interrupting rating fuse. If the supply connection is made directly to the battery, the fuse should be installed in the
positive lead within 5 inches of the battery positive (+) terminal.
Caution The VX power supplies are sealed per IPXX. Usage in areas where moisture can affect the power supply connections
should be avoided. The power supply should be mounted in a dry location within the vehicle or placed in a suitable
protective enclosure.
Caution:
For installation by trained service personnel only.
Warning: Risk of ignition or explosion. Explosive gas mixture may be vented from battery. Work only in well ventilated area.
Avoid creating arcs and sparks at battery terminals.

Connecting the Vehicle Electrical Connection
Please review the proper wiring illustration, later in this document, before beginning power cable install. If connecting a VMC, the com-
puter must be powered off. If connecting a HHC cradle/dock, the cradle must be empty.
1. Connect the power cable to the VMC or the HHC cradle.
2. Route the cable from the VMC or HHC cradle to the DC-to-DC converter and, optionally for some VMCs, to the screen blanking box.
3. Cut the cable to length and strip the wire ends. If the screen blanking feature is not used for the Thor VX8 or Thor VX9, do not strip
the green and yellow wires.
4. Route the power cable the shortest way possible. 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.
5. Remove the lid from the DC-to-DC converter.
6. Strip the ends of the wires in the cable from the VMC or HHC cradle and attach the wire ends to the output side of the DC-to-DC
converter.
7. Strip the ends of the wires in the cable that will connect to vehicle power and attach
the wire ends to the input side of the DC-to-DC converter.
Note: 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.
The input and output blocks also each have two (chassis
ground).connections. When the diagram indicates a chassis ground
connection, use either chassis ground connector in each block.
Note: Wire colors depend on the type of device attached. Please refer to the
illustrations later in this document for wire colors.
8. Use looms and wire ties to secure all wiring as shown.
9. Reattach the cover with the screws.
10. If the screen blanking box is used for a Thor VX8 or Thor VX9 installation, attach the stripped green and
yellow wire ends to the box. Refer to the applicable following diagram for proper wiring connection.
11. If the screen blanking box is used for a Thor VM1 or Thor VM2 installation, connect a serial cable from
the COM port on the Mount Smart Dock to the box. Refer to the applicable following diagram for proper
wiring connection.
12. Connect the DC-to-DC converter to the vehicle’s electrical system.
13. While observing the fuse requirements specified above, connect the power cable as close as possible to 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. If the screen blanking box is used for a VMC installation, connect the box to vehicle motion circuitry and ground. Refer to the
applicable following diagram and the label on the screen blanking box for proper wiring connection.
15. 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 (1mm2) conductors.
16. 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 the outer cable jacket.
Caution: For battery powered vehicles:
+ is connected to battery positive.
- must be connected to battery negative.
GND must be connected to the vehicle chassis
ground.
For internal combustion engine powered vehicles:
+ is connected to battery positive.
- is connected to battery negative.
GND is connected to the vehicle chassis ground,
which can also be battery negative.
