HAL-LED-174W
WARNING
Do not open or remove luminaire with the circuit energized.
Do not use this luminaire on ungrounded systems. Failure to ground this luminaire can result in
an electric shock, which may be fatal.
Do not use on ungrounded 480 Volt circuits.
CAUTION
Do not look directly at the LEDs when energized.
NOTICE
Do not touch the LEDs; touching could leave oily deposits, causing hot spots and potential
premature failure.
When installing in a hazardous location, it is necessary that the door frame assembly (with lens)
be in place and tightened down properly onto the luminaire. This door frame assembly should
also be cleaned periodically to maintain lighting efficiency.
This luminaire is designed for and should be installed in accordance with the National Electrical
Code/Canadian Electrical Code and all applicable local codes.
Marine and Hazardous Locations
Suitable for use in areas rated Class I, Division 2, Groups A, B, C, and D.
To reduce the risk of ignition of hazardous atmospheres, disconnect the luminaire from the
supply circuit before opening. Keep tightly closed when in operation.
Make sure to tighten all unused close-up plugs to 400 in. –lb. after applying TLNC4 grease.
TLNC4 grease shall be applied in 3 lines, spaced approximately 120° apart, perpendicular to the
threads.
Where flexible cord is used, it should be approved for extra hard, wet location usage and shall
have a separate ground conductor.
MOUNTING OPTIONS
Yoke Mounting
The luminaire must be mounted vertically using the yoke provided in accordance with the instructions
specified; with the lens facing forward and such that the two conduit entries by the yoke are facing
vertically upward or downward. The light may be rotated a maximum of 30 from the vertical plane such
that the lens will be facing down. The light must not be rotated such that the lens will be facing up ay

any angle. Care must be taken to ensure that dust does not accumulate on the glass lens surface and on
the cooling fins at the back.
The LED luminaire with yoke (supplied) will mount directly onto flat surfaces. The yoke has a center
clearance hole for a ½” clearance holes spaced 3- ½” apart on the yoke center line.
1. Mount the luminaire with yoke to a flat surface using user-supplied hardware.
2. Slightly loosen the four yolk bolts and tilt the luminaire to the desired position with your free
hand.
3. Retighten the bolts to secure the luminaire in place.
Optional Crossarm Mounting Bracket
1. Mount the luminaire with yoke to the crossarm mounting bracket with two ½” mounting bolts
(supplied) and two ½” lockwashers (supplied).
2. Mount the crossarm mounting bracket to a flat surface with on ¾” bolt (not supplied). The
crossarm mounting bracket may be locked into position with a 3/8”bolt (not supplied).
Optional Crossarm Mounting Bracket & Optional Pipe/Wall Mount Bracket
1. Mount the pipe/wall mount bracket to a flat surface with user-supplied hardware OR clamp to a
pipe or pole (1”to 2 ½”) with U-Bolt and nuts (supplied). Tighten nuts to secure in position.
2. Mount the luminaire with yoke to the crossarm mounting bracket with two ½” bolts (supplied)
and two ½” lockwashers (supplied).
3. Mount the luminaire with yoke and crossarm mounting bracket (attached) to the pipe/wall
mount bracket with one ¾” bolt (supplied).
4. Install one 3/8”bolt (supplied) through the crossarm mounting bracket and into the pipe/wall
mount bracket.
5. Aim the luminaire in the desired direction and tighten the 3/8”bolt to lock in place.
Optional Poletop Slip-Fitter
Note: Flexible cord or cable shall be used for extra hard, wet locations and have a temperature rating as
indicated on the luminaire nameplate. The cord/cable should have a diameter between ½” and 5/8”(13
mm-16 mm). Cords/cables outside of this range may prevent the proper functioning of the pressure
plate and cord grip assembly, and may result in water ingress. Make sure to tighten all unused close-up
plugs to 400 in. lb. after applying TLNC4 grease. TLNC4 grease shall be applied in 3 lines, spaced
approximately 120° apart, perpendicular to the threads.
1. Loosen the two screws on the pressure plate for cord/cable entrance.
2. Feed the supply cord/cable up through the poletop slip-fitter and out through the cord grip
assembly. Leave at least 10”(254 mm) of slack to make connections inside the luminaire.
NOTE: #16 AWG (1.5 mm) cord/cable is recommended.

3. Tighten the pressure plate screws.
4. Install the poletop slip-fitter onto a 1 –½” or 2”pole. Tighten the three locking bolts.
5. Mount the luminaire with yoke to the poletop slip-fitter using the mounting bolt (supplied).
Tighten the mounting bolt in place.
Optional Poletop Slip-Fitter
Note: Flexible cord or cable shall be used for extra hard, wet locations and have a temperature rating as
indicated on the luminaire nameplate. The cord/cable should have a diameter between ½” and 5/8”(13
mm-16 mm). Cords/cables outside of this range may prevent the proper functioning of the pressure
plate and cord grip assembly, and may result in water ingress.
1. Loosen the two screws on the pressure plate for cord/cable entrance.
2. Feed the supply cord/cable up through the poletop slip-fitter and out through the cord grip
assembly. Leave at least 10”(254 mm) of slack to make connections inside the luminaire.
NOTE: #16 AWG (1.5 mm) cord/cable is recommended.
3. Tighten the pressure plate screws.
4. Install the poletop slip-fitter onto a 1 - ½” or 2”pole. Tighten the four locking bolts.
5. Mount the luminaire with yoke to the poletop slip-fitter using the two luminaire mounting bolts
(supplied). Tightly secure the bolts.
Pendant Mounting
This LED luminaire has a conduit entry (3/4”NPT) located on the back of the luminaire for pendant
mounting.
1. Thread the luminaire onto a ¾” NPT conduit stem.
Note: A brace is required on conduit stems longer than 12 inches (NEC Requirement).
2. Tighten down the external set screw to secure in place.

CHAIN MOUNTING
This LED luminaire has four ¼-20 UNC-2B threaded holes located on the back of the luminaire for chain
mounting.
1. Thread the four eye bolts (supplied) into the ¼ - 20 UNC-2B threaded holes on the back of the
luminaire housing.
2. Assemble/attach the chain assemblies to the eye bolts. One chain assembly per side is provided
for the luminaire housing.
WIRING
WARNING: The luminaire must be grounded as required by the National Electrical Code (Paragraph
410-21 and Article 250) or Canada Electric Code (Rule 30-500 and Section 10). Verify that the ground
continuity has been established by using an OHM meter to other suitable testing equipment before
energizing the luminaire. Failure to properly ground the luminaire will create an electric shock hazard,
which can cause serious injury or death.
1. Open the luminaire by loosening the four captive screws. Allow the cover to swing open,
exposing the wiring compartment.
2. A. Wiring with Cable
1. Strip the cable outer jacket as required
2. Insert the cable through the conduit entry (with appropriate fitting attached) to the
luminaire wiring compartment.
B. Wiring with Individual Conductor Wire
1. Run conductors down through the conduit to the luminaire wiring compartment.
Note: See the product nameplate for supply wire requirements. The terminal block can
accept 24-10 AWG wire. Use the appropriate wire gauge based on the application.
3. Strip the individual conductors to bare wire and insert then into the proper terminal block
connections. The connection points are identified on the terminal block as:
“L” = Line, “N” = Neutral, “G” = Ground. Tighten down the terminal block screws onto the wire.
4. Once the terminal block is wired to incoming power, close the luminaire cover and tighten the
four captive screws.
5. Close all unused conduit entries with conduit plugs (2 Supplied). Make sure to tighten all unused
close-up plugs to 400 in. –lb. after applying TLNC4 grease. TLNC4 grease shall be applied in 3
lines, spaced approximately 120° apart, perpendicular to the threads.
6. Power can now be applied to the luminaire.
