3. 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.
IMPORTANT:
For uninterrupted power, electrical supply connections should not be made at any point
after the ignition switch of the vehicle.
4. Route the cable the shortest way possible. The input cable from the connection to the battery
is rated for a maximum temperature of 60°C (140°F). When routing this cable it should be
protected from physical damage and from surfaces which might exceed this temperature.
Additionally do not expose the cable to chemicals or oil that may cause the wiring insulation
to deteriorate.
Note: If the vehicle is equipped with a panel containing Silicon Controlled Rectifiers
(SCR's), avoid routing the power cable in close proximity to these devices.
Always route the cable so that it does not interfere with the operator's safe operation and
maintenance of the vehicle.
Use proper electrical and mechanical fastening means for terminating the cable. Properly
sized "crimp" type electrical terminals are an accepted method of termination.
Wiring color codes for LXE supplied DC input power cabling:
Vehicle Supply Wire Color
+24-60VDC (DC +) White
Return (DC -) Black
Vehicle Chassis (GND) Green
Figure 16 Vehicle Connection Wiring Color Codes
Note: The input power cord for the DC-DC Power Supply uses white, black and green
wires. Some LXE products have DC input power cords with brown, blue and green
wires. The previous table shows the correct electrical connection for either type of
cable.
5. 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.
6. Connect the Power Supply to a terminal block. Terminal blocks and any additional cabling
(such as a festoon cable) between them must be supplied by the customer. The customer
supplied cabling must be 18 AWG or heavier gauge, 250” (635 cm) or less in length and
provide not less than 11.2 VDC at the RX2.
