WARNING GENERAL
1. DO NOT MODIFY UNIT IN ANY WAY. Modication may
affect safety and reliability.
2. Improper use or failure to follow these instructions
could result in serious injury or property damage.
3. Operator should be instructed in the safe and proper
usage and maintenance of this product.
WARNING ELECTRICAL
1. Disconnect electrical power before installation,
adjustment and maintenance.
2. DO NOT overload; the amperage and voltage indicated
on the nameplate must not be exceeded.
3. Check continuity before connecting electrical power.
4. All installations must comply with applicable local
and/or National Electrical Code®.
5. Before installing check xture unit nameplate and
carton labels to be sure you have correct xture and
mounting hood. Circuit must be deactivated before
installing xture.
CAUTION GENERAL
1. All A-51 LED Series Fixtures are to be mounted
vertically with globe facing down.
The xture unit must be installed with one of the following
mounting hoods for safe operation. Failure to use fixture
unit with one of the following mounting hoods voids
warranty as well as the UL Listing and creates the risk of
re or explosion.
Fixture unit must be installed with:
AAP-50, AAP-75,
AAP-100, AEP-50,
AEP-75, or AEP-100
Pendant Hood
AAC-50, AAC-75,
AAC-100, AEC-50,
AEC-75 or AEC-100
Ceiling Hood
AALB-50, AALB-75,
AALB-100, AELB-50
AELB-75 or AELB-100
Long Wall Bracket Hood
FIXTURE INSTALLATION DIRECTIONS
1. Use the installation drawing as a guide. Install mounting
hood rst as all wiring connections are made in the
mounting hood. The xture unit requires no internal
wiring connections.
• I nstall mounting hood to conduit system (and/or wall,
ceiling or stanchion). If using pendant or stanchion
mounting hood, secure the hood to the conduit system
with the set screw.
2. Remove the connection block (VPT7) from the mounting
hood by loosening (but not removing) the two Phillips head
screws. Turn connection block counter-clockwise to remove.
3. When using ceiling bracket, long wall bracket, or short
wall bracket, mounting hoods, threaded adapter
(59064050000) can be removed by lifting gasket
(59064034000) to access set screw.
• Loosen set screw and turn adapter counter-clockwise for
easier access to junction box. If long bracket (AALB-)
is being used, bracket can be removed from junction box
by loosening set screw in flange and turning
counter-clockwise.
4. Pull supply wires from the conduit into the junction box.
Make connection of supply wires to the VPT-7 connection
block by attaching “HOT” voltage lead to the black wire
and common “neutral” lead to the white wire on the
connection block.
5. Secure threaded adapter (where applicable) or long
bracket (where applicable) to junction box and tighten
all set screws.
6. Secure VPT-7 connection block to threaded adapter or
mounting hood by slipping over Phillips head screws,
turning clockwise and tightening screws.
7. Inspect threads of mounting hoods and the xture unit to be
sure they are clean and free of damage.
• Inspect globe for any chips, scratches or cracks.
CAUTION GENERAL
Chipped, scratched or cracked
globes will fail. Replace any
such defective lamp housing.
8. Thread the fixture unit into mating threads of
mounting hood until tight against gasket of mounting
hood. Locking spring of xture unit should engage with
notches on mounting hood.
9. Install guard and/or reector if desired. Check tightness of
set screws and all threaded joints. Activate supply circuit
to test xture.

LONG BRACKET INSTALLATION
1. Remove bracket from junction box, pull through
leads to connector block. Attach ground wire to
grounding screw.
2. Remove Connector block from threaded adapter,
p
ull leads through to connect wires t
wires on block. Black lead is “line” lead and “white”
lead is “neutral.”
3. Push block into place and tighten screws. Install
xture. NOTE: Plugs should be removed and
resealed with pipe sealant.

MAINTENANCE DATA
• To maintain maximum light output from this xture, it should be cleaned periodically as follows:
1. Alkaline or acidic cleaners will attack the protective coating of epoxy on the xture and should not be used.
The aluminum exterior of this fixture should be cleaned only with a mild soap or cleaner, and should
be rinsed with water immediately. This will allow the epoxy to protect the xture from corrosive elements in
the atmosphere and result in longer xture life.
2. The glass globe should be cleaned using a soft cloth and a non-abrasive cleaner. The globe should be
regularly inspected for scratches or chips. If the globe is scratched or chipped, it must be replaced.
3. The porcelain enamel reector may be cleaned with any non-abrasive detergent or glass cleaner.
• These periodic cleaning procedures are important to prevent the accumulation of dust and dirt which will
impair the light output of the xture.
• When removing and repairing the xture, lubricate threads only with Appleton TLC-3 conductive, high
temperature lubricant. This should only be necessary if threads are no longer coated with the blue or black
color of the dry lm lubricant.
• See the next page for drawings and a complete parts list.
OPERATIONAL DATA
• The xture must be operated in an environment that does not exceed 55°C.
• The xture may be operated on AC power only up to 277 VAC and 300 VDC.
WARNING:
• To reduce the risk of re or explosion, do not install where the operating temperature exceeds
ignition temperature of hazardous atmospheres.
• Refer to the nameplate on the xture for maximum operating temperature and for proper
fixture classication.
