Machine wiring guidelines
•
Protect wires from mechanical abuse, run wires in flexible metal or plastic conduits.
•
Use 85˚ C (185˚ F) wire with abrasion resistant insulation and 105˚ C (221˚ F) wire should be
considered near hot surfaces.
•
Use a wire size that is appropriate for the module connector.
•
Separate high current wires such as solenoids, lights, alternators or fuel pumps from sensor and other
noise-sensitive input wires.
•
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.
•
Do not run wires near sharp metal corners, consider running wires through a grommet when
rounding a corner.
•
Do not run wires near hot machine members.
•
Provide strain relief for all wires.
•
Avoid running wires near moving or vibrating components.
•
Avoid long, unsupported wire spans.
•
Ground electronic modules to a dedicated conductor of sufficient size that is connected to the
battery (-).
•
Power the sensors and valve drive circuits by their dedicated wired power sources and ground
returns.
•
Twist sensor lines about one turn every 10 cm (4 in).
•
Use wire harness anchors that will allow wires to float with respect to the machine rather than rigid
anchors.

Caution
Unused pins on mating connectors may cause intermittent product performance or premature failure.
Plug all pins on mating connectors.
W
Warning
Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.
Improperly protected power input lines against over current conditions may cause damage to the
hardware. Properly protect all power input lines against over-current conditions.
Machine welding guidelines
W
Warning
High voltage from power and signal cables may cause fire or electrical shock, and cause an explosion if
flammable gasses or chemicals are present.
Disconnect all power and signal cables connected to the display before performing any electrical welding
on a machine.
The following is recommended when welding on a machine equipped with electronic components:
•
Turn the engine off.
•
Remove electronic components from the machine before any arc welding.
•
Disconnect the negative battery cable from the battery.
•
Do not use electrical components to ground the welder.
•
Clamp the ground cable for the welder to the component that will be welded as close as possible to
the weld.
