Recommended Wiring Practices

This section contains information about the display
connectors and pin outs. Please use the following
recommended wiring practices when installing and
using the display:
Ensure correct and adequate single point ground to
•
prevent ground loops.
Use twisted or twisted shielded pair cable for CAN
•
per the applicable standard.
Confirm that the CAN network is properly
•
terminated using 120 Ω resistors.
Ensure the appropriate sized conductor cross
•
section is specified for the intended load current in
the harness design.
Note: Please review individual overcurrent shutdown values in
the configuration and use the correct wire gauge conductor to
accommodate maximum load current configured.
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 and impact).

! 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.
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 sufficient clearance from moving parts.
Wires routed through holes in the vehicle body/
chassis should use grommets.
Avoid sharp metal edges, fasteners and other
abrasive surfaces or use protective shielding when
routing harness assembly.
Route wires to avoid exhaust system components
or other high temperature areas. Use appropriate
heat shielding or 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
display supply current.
Note: 5A fuse maximum is typical. Verify that wiring can
handle more current than the fuse rating.
