DFLA LED luminaires
Installation & maintenance information
APPLICATION
DFLA LED luminaires are suitable for use in the following hazardous (classified)
locations as defined by the National Electrical Code (NEC
DFLA:
NEC/CEC:
• Class I, Division 2, Groups A, B, C, D
• Class I, Zone 2
• Wet Locations, Type 4X, IP66
UL Standards:
• UL 844 Hazardous (Classified), UL1598 Luminaires, UL1598A Marine, UL8750
• CSA 22.2 No. 137
Refer to the luminaire nameplate for specific classification information, maximum
ambient temperature suitability and corresponding operating temperature (T-code).
DFLA LED luminaires construction is designed for use indoors and outdoors in marine
and wet locations, where moisture, dirt, corrosion, vibration and rough usage may be
present.
To avoid the risk of fire, explosion or electric shock, this product should be
installed, inspected and maintained by a qualified electrician only, in accordance
with all applicable electrical codes.
To avoid electric shock:
• Be certain electrical power is OFF before and during installation and
maintenance.
• Luminaire must be supplied by a wiring system suitable per local code with
an equipment grounding conductor.
To avoid burning hands:
• Make sure LEDs and drivers are cool to touch when performing
maintenance.
INSTALLATION
Mounting
Yoke Mount - Wall Mount Using Luminaire Yoke Only
1. Using luminaire yoke as a template, mark and drill desired location on mounting
surface.
2. Secure luminaire yoke to surface using ½" bolts or lag screws (not provided).
WIRING
Wiring the Luminaire
1. Open back cover/heat sink by loosening nine (9) #10-24 x 0.75" stainless steel
cover bolts using a 5/8" nut socket or flat head screwdriver (see Figure 1). The
heat sink cover should be removed by pulling back on one corner of the top
most edge to prevent damage to gasket.
NOTE: To avoid pinching hazard between the heat sink cover and driver housing,
ensure that the luminaire is oriented in the vertical position before, and during wiring
procedure.
DO NOT PLACE ADDITIONAL WEIGHT ON THE BACK COVER/HEAT SINK

DFLA LED luminaires are supplied for use with a choice of voltages:
• 100-277 VAC, 50/60 Hz
• 127-250 VDC
• 347-480 VAC, 50/60 Hz
DFLA LED luminaires are compliant with the regulation on the assessment of product
compliance for explosive atmospheres.
To avoid explosion:
• Make sure the supply voltage is the same as the rated luminaire voltage.
• Do not install where the marked operating temperatures exceed the
ignition temperature of the hazardous atmosphere.
• Do not operate in ambient temperatures above those indicated on the
luminaire nameplate.
• Use only replacement parts from Crouse-Hinds.
• Use proper supply wiring as specified on the luminaire nameplate.
• All surfaces must be clean.
• Before opening wiring compartment, electrical power to the luminaire
must be turned off and area must be free from hazardous atmosphere.
Keep tightly closed when in operation.
• To minimize the risk from electrostatic discharge, when cleaning, wipe the
lens with a clean, damp cloth.
• LED compartment is non serviceable
2. All components in the luminaire are pre-wired so only line in, neutral and ground
need to be connected in the luminaire using the terminal block, using methods
that comply with all applicable codes. Insert wires into terminal block by
pressing down on tabs. Be sure wires are spaced as shown in Figure 2.
• Wire range from AWG 18-14 (0.75 - 2.5mm²) for neutral, and line (strip
length 0.43" [10.9mm]), and AWG 16-14 (1.5 - 2.5mm²) for ground
connections (strip length 0.43" [10.9mm]).
• Entries to driver housing shall be sealed, using HTL, STL or Slipkote 577
with devices rated a minimum of IP66.
• Standard openings are 3/4" NPT.
• Optional openings are M20 (20mm) and/or M25 (25mm).
• Secure all electrical connections and wiring entry glands.
• Ensure that the following lengths for field wiring, internal to the driver
housing compartment, are followed:
– 4.5" ± 0.25" (114 ± 6mm) for ground wire
– 2.5" ± 0.25" (64 ± 6mm) for neutral wire
– 2" ± 0.25" (51 ± 6mm) for line in wire
