RECOMMENDED WIRING PRACTICES
This section contains information about the controller
connectors and pin outs. Please use the following
recommended wiring practices when installing and using the
controller:
Ensure correct and adequate single point ground to
•
prevent ground loops.
Use twisted or twisted shielded pair cable for CAN
•
per the applicable standard.
Con rm that the CAN network is properly terminated
•
using 120 resistors.
Ensure the appropriate sized conductor cross section is
speci ed for the intended load current in the harness
design.

Note: Please review individual overcurrent shutdown values
in the con guration and use the correct wire

con gured
Make sure that voltage drops are kept within reasonable
•
levels under maximum continuous load conditions e.g. 1
volt on 12-volt systems and 2 volts on 24 - volt systems.
Verify that the harness is constructed to meet the needs
•
of the application environment
(e.g. shock, vibration, moisture, temperature, chemicals,
5.282
and impact).
134.17
Make certain that the harness is designed and constructed
•
to minimize induced interference resulting from EMI
coupling between signal wires.
Separate power circuits from low - level signals.
•
All splices (soldered or crimped) should use adhesive
•
lined heat shrink tubing.
Make provisions for drip loops to attach devices in
•
exposed locations and prevent moisture entry and
formation.
Provide su cient clearance from moving parts.
•
Wires routed through holes in the vehicle body/chassis
•
should use grommets.
2X 2.305
Avoid sharp metal edges, fasteners, and other abrasive
58.55
•
surfaces or use protective shielding when routing harness
assembly.
Route wires to avoid exhaust system components or other
4X .379
•
high temperature areas, use appropriate heat shielding or
9.61
other insulation where routing is a problem.
Avoid routing near wheel wells or provide adequate
•
mechanical protection to the assembly.
Use a protective fuse sized appropriately for the
•
2.305
controller supply current.
58.55
Note: typical maximum load current is 60% - 80% of fuse
rating. Verify that wiring can handle more current than the
fuse rating. Note the following guideline for maximum
fuse recommendations:

! Warning: Prior to Welding
In order to avoid damaging the HFX controller ensure that all electrical
connectors are fully disconnected from the HFX controller prior to
welding on the machine.
