(Open & Enclosed)

READ THOROUGHLY BEFORE INSTALLING

Save instructions for future use.

WARNING

Risk of electric shock

• Turn power off before servicing
– see instructions

NOTE: Maximum fixture ambient temperature rating is determined by the lesser rating as
indicated on the ballast assembly and the optical assembly.

GENERAL

This luminaire is designed for indoor (check label for damp or wet location suitability) applications,
and should be installed and maintained according to following recommendations. It consists of three
assemblies, ballast, optical, and socket assembly, which may be shipped separately.

If the luminaire you ordered has a polycarbonate or acrylic refractor, please pay particular attention
to the following statement:

Any part damaged or broken during or after assembly should be replaced.

All polycarbonates, acrylics and articles made from polycarbonates or acrylics will yellow with time.
The rate of yellowing is determined by the specific material, any additives and coatings, as well as the
optical temperature and exposure to ultraviolet (UV) light.

This yellowing can reduce the light output and impact resistance of products made from polycarbonates
or acrylics. In no case should the maximum wattage recommendations listed for the luminaire be
exceeded. Contact factory for more information.

UNPACKING

This luminaire has been properly packed so that no parts should have been damaged during transit.
Inspect to confirm.

No damaged parts should be installed.

MOUNTING

Conduit Mounting:

1. Fasten mounting plate (minimum of five full turns) to 3/4-inch conduit by threading the mounting plate
onto conduit. (Figure 1)

2. Tighten set screw to lock mounting plate to conduit.

3. Loosen set screw on the top corner of the ballast housing.

4. Loosen wiring box door screws on the ballast housing to allow the wiring box door to pivot.

5. Pivot the wiring box door 180 degrees to allow the mounting plate room to slide onto the ballast
housing.

6. Slide mounting plate onto ballast housing, making sure that the upper rim of the ballast housing slides
into the rails of the mounting plate. (Figure 2)

7. Tighten the set screw on the top corner of the ballast housing so that the mounting plate cannot back out.

8. After wiring is complete, pivot the wiring box door back into the original position and tighten the two
wiring box door screws.

Figure 1

NOTE: The luminaire is supplied with a mounting plate, which is included in carton with the ballast
housing.

INSTALLATION

CAUTION

Unit will fall if not installed properly

• Follow installation instructions

NOTE: Minimum clearance of 3 feet must be maintained below luminaire.

Flexible Mounting: If flexible mounting accessories (hook or loop) are supplied separately, thread

shaft into mounting plate and follow instructions above for conduit mounting.

CAUTION: If this instruction is not followed damage to the mounting parts can occur causing the fixture
to fall. When using hook or loop fixture mounting, do not apply luminaire weight when the mating parts
are as shown in Fig. A. Do not apply any twisting action to the hook and loop assembly. When properly
installed the hook and loop assembly is shown in Fig. B.

WARNING

Risk of fire

• Keep combustible materials away from

lens – see instructions

• Use lamps specified on nameplate

These instructions do not purport to cover all details or variations in equipment nor to provide for every possible contingency to be met in connection with installation, operation or
maintenance. Should further information be desired or should particular problems arise which are not covered sufficiently for the purchaser’s purposes, the matter should be referred
to GE Lighting Solutions.

WIRING

Make all electrical connections in accordance with the National Electrical Code and any applicable
local code requirements.

Verify that supply voltage is correct by comparing it to nameplate.

If unit is designated as multivolt or multiwatt, follow specific instruction.

Installer needs to connect supply conductors to primary leads and fixture ground wire. These wires
are located on the small wiring harness that contains the 9-pin plug. After these wires are connected, the
9-pin plug wired in the fixture needs to be mated with the 9-pin plug wired to the supply conductors
(assuming that they are not already connected). Removal of the 9-pin plug does not hinder the electrical
performance of the luminaire.

NOTE: Attach ground conductor to the green ground wire supplied with the fixture.

SAFETY CHAINS

CAUTION: When used, safety chains must be carefully installed as outlined below.

Safety chains may be attached to luminaire when user feels safety chains should be used. Safety
chains should be attached in a manner to give minimum slack. In no case should a ballast or optical safety
chain be installed in a manner which permits luminaire to fall more than six (6) inches before it is caught
by chain. To install ballast safety chain, insert “S’’ hook through hole in housing and crimp shut. Safety
chains and attachment accessories are available from factory as an optional accessory for both ballast
and optical assemblies.

To install optical safety chain, insert “S” hook through a link in ballast safety chain and crimp shut. Use
snap hook to attach to clip or hole on optical. See figure 4.

FINAL ASSEMBLY
OPTICAL ASSEMBLY/MOUNTING—

1. Secure reflector to bottom of ballast housing using two of the four screws provided. Installation is
aided by key hole slots in reflector. On VBC units with safety chains, orient the reflector so that the
ballast and reflector holes are on the same side.

2. Using the remaing two screws attach the pan. Installation is aided by key hole slots in bracket.

3. Refer to LAMP INSTALLATION and snap lamp into socket.

4. (For enclosed units only) Close door and secure properly in place by latching first latch opposite hinge,
followed by other latches.

LAMP INSTALLATION/REPLACEMENT

CAUTION

Risk of burn

• Allow lamp/fixture to cool before handling

The light output of a luminaire is dependent on the age of the lamp. In applications where light level
is critical it may be desirable to replace lamps before they burn out. Lamp manufacturer can provide
data showing how lamp light output decreases with use.

Use only lamps specified on socket ASM lamp label. Observe lamp manufacturer’s recommendations
and restrictions on lamp operation, particularly ballast type, burning position, etc.

MAINTENANCE

It will occasionally be necessary to clean outside of refractor to maintain light level. Frequency of
cleaning will depend on ambient dirt level and minimum light level which is acceptable to user. Lens door
(if enclosed) should be washed in a solution of warm water and any mild,
non-abrasive household detergent, rinsed with clean water and wiped dry. Should optical assembly
become dirty on inside, wipe reflector and clean lens door in above manner, and replace any damaged
gasket.
