Wiring Recommendations y All wires must be protected from mechanical abuse. Wires should be run in flexible metal or plastic
conduits.
y Use 85˚ C [185˚ F] wire with abrasion resistant insulation. 105˚ C [221˚ F] wire should be considered
near hot surfaces.
y Use a wire size that is appropriate for the module connector.
y Separate high current wires such as solenoids, lights, alternators or fuel pumps from sensor and
other noise-sensitive input wires.
y Run wires along the inside of, or close to, metal machine surfaces where possible. This simulates a
shield which will minimize the effects of EMI/RFI radiation.
y Do not run wires near sharp metal corners. Consider running wires through a grommet when
rounding a corner.
y Do not run wires near hot machine members.
y Provide strain relief for all wires.
y Avoid running wires near moving or vibrating components.
y Avoid long, unsupported wire spans.
y All analog sensors should be powered by the sensor power source from the PLUS+1 Controller.
Sensor rounds should be returned to the machine control system
common ground.
y Sensor lines should be twisted about one turn every 10 cm (4 in).
y It is better to use wire harness anchors that will allow wires to float with respect to the machine
rather than rigid anchors.
y All machine electronic modules should be grounded to a dedicated control system ground that
consists of a conductor of sufficient size that is connected to the
battery (-).
y If a CAN shield is used, the shield must be grounded to the machine control system ground and the
CAN shield pin on the TMC controller.
