WARNING
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.
WARNING
To avoid electric shock:
• Be certain electrical power is OFF before and during installation and
maintenance.
• Floodlight 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.
WARNING
To avoid explosion:
• Make sure the supply voltage is the same as the rated floodlight 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
floodlight nameplate.
• Use only replacement parts from Eaton’s Crouse-Hinds Division.
• Use proper supply wiring as specified on the floodlight nameplate.
• All surfaces must be clean.
• LED compartment non-serviceable. Do not open.
• Before opening wiring compartment, electrical power to the floodlight
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.
INSTALLATION
Mounting
Yoke Mount - Wall Mount Using Floodlight Yoke Only
1. Using floodlight yoke as a template, mark and drill desired location on mounting
surface.
2. Secure floodlight yoke to surface using ½” bolts or lag screws (not provided).
WIRING
Wiring the Floodlight
1. Open back cover/heat sink by loosening nine (9) #10-24 x 0.75” stainless steel
cover screws using a 5/16” 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 heat sink cover and driver housing, ensure
that floodlight is oriented in vertical position before, and during, wiring procedure.
2. All components in the fixture are pre-wired so only line in, neutral and ground
need to be connected in the fixture using the supplied Wago connectors, using
methods that comply with all applicable codes. See Figure 2 for wiring diagram.
• 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 or STL, with
devices rated a minimum of IP66.
• Standard openings are M20, M25 or 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
APPLICATION
LED floodlight construction is designed for use indoors and outdoors in marine and wet
locations, where moisture, dirt, corrosion, vibration and rough usage may be present.

    What to do if the Power LED is not lit on my Eaton Industrial Electrical?
    • A
      Angela MatthewsAug 20, 2025
      If the Power LED is not lit on your Eaton Industrial Electrical, you should first check the polarity and integrity of the trunk cable connections to the enclosure. Also, verify that the d.c. supply powering the incoming trunk is operating correctly.

    What to do if alarms on my Eaton Security System remain on and cannot be reset?
    • L
      Lee MosleyAug 25, 2025
      If alarms are set to operate from normally closed contacts and the signal supply fuse blows, all alarms will operate as though an alarm has occurred. To resolve this, check the signal supply fuse F1 (rated at 125mA), located in the top right-hand corner of the unit when viewed from the rear, to see if it has blown. Also, ensure that the inputs have been correctly set to operate from either a normally open (N.O.) or normally closed (N.C.) configuration and haven't been accidentally inverted.

    How to fix the audible alarms not sounding on my Eaton Security System?
    • R
      Ruth AlvarezAug 27, 2025
      Each channel can be selected to operate either of the two integral horns / horn relays as required. Internal horns and horn relays are enabled by placing the following switches to the ON position on the SPR Card: HNA – SW5 - Position 5, HNB – SW5 - Position 6. Each pair of channels can be set to activate either of the audibles using the following switches located on each alarm module: Channel 1 & 2 HNA – SW4 Position 7 set to ON, HNB – SW4 Position 8 set to ON; Channel 3 & 4 HNA – SW6 Position 7 set to ON, HNB – SW6 Position 8 set to ON.
