The following guidelines are recommended when machine is equipped with a PLUS+1 mobile
machine display.
Wiring
y
Protect wires from mechanical abuse, run wires in flexible metal or plastic conduits.
y
Use 85˚ C (185˚ F) wire with abrasion resistant insulation and 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
Power the analog sensors by the sensor power source from the module and ground returned to
the sensor ground pin on the module.
y
Twist sensor lines about one turn every 10 cm (4 in).
y
Use wire harness anchors that will allow wires to float with respect to the machine rather than rigid
anchors.
Ground electronic modules to a dedicated conductor of sufficient size that is connected to the
battery (-).
