E-EQ-RX2OGWW-B RX2 User’s Guide
How To: Connect Vehicle 12VDC Connection
1. The RX2 must be turned off and the power cable must be UNPLUGGED from the
RX2.
2. While observing the fuse requirements specified above, connect the power cable to the
terminal block or as close as possible to the actual battery terminals of the vehicle.
When available, always connect to unswitched terminals in 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.
Note: If it is necessary to shorten the power cable, please note that there are five
wires inside the cable. The two extra wires are not used for the RX2 and can
be removed.
3. 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.
Note: If the vehicle is equipped with a panel containing Silicon Controller 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 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.
Please select electrical connectors sized for use with 18AWG (1mm
2
) conductors.

4. 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.
5. If necessary, the power cable can be extended using customer supplied components
such as terminal blocks and a festoon cable. Any cables 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.
