Note: Due to the surge protection provided in the fixture to protect the internal electronics and LEDs, a branch
circuit with the LED fixture may false fail a megohmmeter test (sometimes referred to as a megger test). If a
megohmmeter test is required, the LED fixture should be removed from the branch circuit.
Note: Multiple fluorescent or LED fixtures attached to a single Ground Fault Circuit Interrupter (GFCI) may cause
nuisance tripping of the GFCI. Regulatory agencies allow a small amount of leakage current because of the circuitry
required to mitigate possible issues with electromagnetic compatibility(reference UL8750 and EN61347). The
summation of these leakage currents from multiple fixtures may be enough to trip a GFCI.
Note: When fitted with a polycarbonate lens, the polycarbonate lens should not be subjected to sunlight.
NOTE- For Class I, Division 1 / Class II, Division 1 / Class I, Zone 1 Hazardous Locations, use rigid conduit
or appropriate cable connectors/ glands rated for Class I, Division 1 Groups BCD
NOTE – Pour les endroits dangereux Classe I, Division 1 / Classe II, Division 1 / Classe I, Zone 1 utiliser des Conduits rigides.
KFLX INSTALLATION INSTRUCTIONS:
Yoke Mounting:
1. For convenience, install the yoke bracket to the fixture before mounting the structure.
2. Loosen bolts - aim the floodlight to the desired spot.
3. Tighten both bolts securely.
4. Fasten the yoke bracket to the mounting location using ½” bolts/fasteners.
5. An “Earthquake Safety Chain” can be looped around the bosses that attach the LED heat sink to the driver box.
Pole Mounting Using Optional Knuckle:
1: Remove the center hub from the driver box. Retain the hub locking nut.
2. Attach the fixture side of the knuckle to the driver box with the four bolts provided and the hub locking nut.
3. Disassemble the knuckle and route the wires through the knuckle from the pipe side. Use stranded .425” (10.8mm)
maximum diameter cable. Attach them to the terminal block inside the light fixture. Reassemble the knuckle, leaving
enough wire below the knuckle to reach down the length of the pole.
4. Drop the wire down the pipe. Thread the pipe side of the knuckle to a 1-1/2”-11.5 NPT pipe. A pipe adapter can be
used for smaller pipes.
5. Aim the fixture appropriately and tighten the fixture in place; to both the pipe and the bolt through the knuckle.
IMPORTANT NOTE:
Make sure that the circuit is de-energized at main fuse or at circuit breaker prior to installation.
NOTE IMPRORTANTE:
Mettre le circuit hors tension grace au fusible principal ou le disjoncteur.
Open the fixture by loosening the swing bolts. Using the terminal blocks supplied, run supply wire to fixture through
applicable hub. Make watertight joint using sealing fittings at appropriate hole. The included hubs are for ¾”- 14NPT. A
½-14NPT reducer is also included. The holes through the cast metal in the driver compartment are for an M25 cable
gland. To use an M25 cable gland, discard the ¾ NPT hubs.
Reattach the swing bolts. Torque the cover bolts until the cover touches the housing. Approximately 3 N-m (25 in-lbf).
Re-energized the circuit to verify the fixture is operating properly
The terminal block shown is with battery back up. Non back up
fixtures will not have the “L2” terminal. Mains wiring should be
brought in to the corresponding marked terminal. Looping
wiring can be accomplished by using the adjacent connection
port. A small screwdriver can be inserted in the slot near the
connection port to ease the force required to insert the wire.
The external ground is located next to the gland/hub opening
where the mains wires exit the fixture.

Conditions for Safe Use:
1. To prevent ignition of hazardous atmospheres, disconnect ballast/fixture from supply circuit before opening. keep tightly
closed when in operation.
2. Do not open, maintain or service in an area where an explosive atmosphere may be present.
3. When Polycarbonate lens is in use, clean lens with damp cloth to avoid static discharge.
4. the luminaire shall only be installed where there is a low risk of mechanical damage.
Battery Backup Fixtures:
IMPORTANT: To turn the fixture completely off, an un-switched AC power source of 120VAC to 277VAC is required for the
yellow/black and white leads. If the yellow/black and white leads are attached to switched power, the fixture will go into battery
backup mode if the switch is turned off.
IMPORTANT: A switched or un-switched AC power source of 120VAC to 277VAC is acceptable for the black lead. Fixtures with
terminal blocks are shipped with a jumper between the terminals of the black and yellow/black wire. Remove the wire link
(jumper) and attach the yellow black wire to line voltage when local switching is required.
The battery must be charged for at least 12 hours prior to testing.
SELF DIAGNOSTIC INSTRUCTIONS / OPERATION: The self diagnostic feature is set from the factory. The
emergency LED driver will conduct a self check for thirty (30) minutes every thirty (30) days; and ninety (90) minutes
or one hundred eighty (180) minutes self check every 12 months. After every self check the LED indicator light will
indicate a status signal. Dip Switch 1 Set to ON will run the emergency function at 10W for at least 90 minutes. Dip
Switch 2 set to OFF will run the emergency function at 5W for 180 minutes. To disable this feature, set the Dip
Switch 2 to the OFF position.
The battery switch must be turned to the “ON” position for the fixture to operate correctly. The fixture will not light up in
battery backup mode until AC power is supplied once while the battery switch is in the “ON” position. Thereafter, the
fixture will operate in battery backup mode when the AC power is off.

MAINTENANCE INSTRUCTIONS:
CAUTION:
Disconnect the supplying circuit before opening fixture or removing optics. To maintain maximum light output, this fixture
should be cleaned periodically. Maintenance procedures sometimes require fixtures to be hosed down for good
housekeeping. The supply circuit must be turned OFF and the fixture lens must be allowed to cool to the ambient room
temperature before cleaning. Only mild, non-abrasive cleaning agents should be used. The force of water applied by a
hose must not exceed 65 gallons per minute coming from a 1” diameter hose applied at a distance of 10 feet.
HIGH VIBRATION AREAS:
Periodic inspection of fastener tightness is required; recommended every six (6) months.

REMEMBER TO SAVE ONE OF THESE SHEETS FOR MAINTENANCE PERSONNEL
New fixtures with batteries can be stored for 2 years in a -20°C to 30°C ambient without a need of recharge. A
fully discharged unit should not be stored more than 6 months without being recharged. There is low voltage
disconnect of the battery to the emergency drivers, however as the batteries still have self-discharge they should
be recharged within 6 months to prevent the cells from permanent capacity loss. For long term storage, turn the
battery switch to the “off” position to prevent the cells from permanent capacity loss.
