HFX Product Family
•
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
controller supply current.
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:
•
All Units: +VBat = 2 A
•
HFX48 :+Load total < 50 A depending upon anticipated load
requirements.
•
HFX32: +Load total < 42 A depending upon anticipated load
requirements.
•
HFX20: +Load total < 34 A depending upon anticipated load
requirements.
•
HFX12: +Load total < 26 A depending upon anticipated load
requirements.
WARNING
On a HFX12m or HFX20m all HFX Load PWR+ pins
(9A, 10A, and 19A) must be connected to the same
supply voltage source. On a HFX12m or HFX20m all
SFX LOAD_PWR- pins (18A, 28A, and 29A) must be
connected to the same supply voltage return point.
On a HFX32m or HFX48m all HFX Load PWR+ pins
(9A, 10A, 19A, 1B, 2B, and 3B) must be connected
to the same supply voltage source. On a HFX32m or
HFX48m all HFX LOAD_PWR- pins (18A, 28A, 29A),
12B, 13B, and 22B) must be connected to the same
supply voltage return point.
Failure to connect all the pins to their respective
sources or returns or to use them to power or ground
other devices may cause internal failures of the HFX
controller, damage to the controller connector, or
damage to the wiring harness, and is not covered by
warranty.
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.
Prior to Electrostatic painting
In order to avoid damaging the HFX controller ensure
that all electrical connectors are fully disconnected
from the HFX controller and that sealed mating
connectors without wires are installed on the HFX
connector ports prior to Electrostatic painting on the
machine.
CAUTION
To maintain the environmental ratings of the HFX
controller all connector locations must have a weather
sealed connector as specified in the technical
specifications installed. A dust plug may be shipped
in the C connector of the controller, it is not an
environmental seal. All connector cavities in each
connector must have either an appropriate sized wire
or the correct sealing plug installed. Torque the A and
B connector, if applicable, to 25-28 in-lbs
(2.82 – 3.16 Nm)
