6.
Disconnect the wire from the - connection of the input block on the old power supply. Connect to the Vin- connection on the new
power supply.
7.
Disconnect the wire(s) from the ground ( ) connection of the input block on the old power supply. Twist together with the ground
wire from Step 4 and connect to the ground (
8.
Reconnect to vehicle power.
Figure 6 – Connecting Other Devices
This power supply can be used with devices other than the computers mentioned in this document. Be sure the device meets the speci-
fications on Page 1 of this document.
To connect the device, follow these general instructions as well as any instructions that came with the device:
1.
Make sure the device is switched off.
2.
Remove the lid from the DC/DC power supply.
3.
Route the power cable the shortest way possible. When routing wiring, it should be protected from physical damage and from
surfaces that might exceed the safe temperature of the wiring. Do not expose the wiring 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.
Strip wire ends as necessary.
5.
Attach the positive wire(+) from the device to Vo+ connection of
the output block on the power supply.
6.
Attach the negative wire (-) from the device to Vo- connection of
the output block on the power supply.
7.
Attach the ground wire from the device to the GND connection
of the input block on the power supply.
8.
Attach a wire from the Vin+ connection on the power supply to
vehicle power positive (+), making sure the connection is within
the input voltage range for the selected power supply.
• In most cases, the power would be connected to an
unswitched source.
• Follow the requirements of the device and install a fuse in the
wire. Follow the cautions and warnings on the first page of
this document. Consult the device's documentation for fuse
specifications.
9.
Attach a wire from the Vin- connection on the power supply to
vehicle power negative (-).
10. Attach a wire from the GND connection on the input block on
the power supply. This same connector was used in Step 4.
• For battery powered vehicles, the ground wire must be connected to the vehicle chassis ground.
• For internal combustion engine powered vehicles, the ground wire is connected to the vehicle chassis ground, which can also be
battery negative.
11. Use looms and wire ties to secure wiring as shown:
12. Reattach the lid to the power supply with screws.
13. Turn the device on.
