WARNING
Risk of electric shock
• Turn power off before servicing
– see instructions
GENERAL
This luminaire is designed for outdoor lighting applications, and should not be used in areas of limited ventilation, or in high ambient temperature enclosures; it should
be installed and maintained according to following recommendations.
UNPACKING
This luminaire has been properly packed so that no parts
should have been damaged during transit. Inspect to
confirm.
INSTALLATION
Reflector Rotation: Reflectors may be rotated such that
socket is in any of four positions. This allows for variations
in beam aiming. In order to rotate the reflector the following procedure should be followed.
1. Rotation is best accomplished before mounting the
luminaire on pole.
2. Note the rear edge of reflector position with respect to
hinges (edge inserted into hinge pocket). Access reflec-
tor by loosening reflector plate to main housing screw
and allowing reflector plate assembly to lie on door
assembly. It is not necessary to detach tether.
3. Remove four screws which attach reflector to reflector
plate.
4. Rotate reflector to desired position, being careful not to
twist socket lead wires.
5. Reattach reflector by re-inserting four screws.
6. Reposition reflector plate by inserting rear edge of plate
into hinge pocket and attach plate to main housing with
screw.
MOUNTING
INSTRUCTIONS
DimensionTM DMA (Arm)
NOTE: Power leads should be pulled as mounting
parts are assembled, verifying that leads are free
and not pinched. Ballast voltage selection is best
accomplished before mounting luminaire. See
Wiring for instruction.
A. ARCHITECTURAL MOUNTING:
(Arm)
1. Install nut plate inside pre-drilled pole with nuts to
inside. Secure with screw provided.
2. Install the two (2) studs ensuring that they fully penetrate the nuts on the nut plate.
3. Align upper and lower guides on inside of mounting
arm with their respective studs and slide it into place
against pole.
4. Open luminaire door by pushing inward on latches
while supporting door. Release reflector plate by loosening plate main housing screw and allow plate to hang
from tether.
5. Install the luminaire and secure with flat washers and
locknuts provided. Align the system as the nuts are
tightened.
CAUTION: Ensure that nuts fully engage the two
studs. Correct tightening of stud nuts is important
to ensure proper function of mounting system.
Torque nuts to 18-22 foot pounds.
CAUTION
Unit will fall if not installed properly
• Follow installation instructions
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.
B. OTHER MOUNTINGS
External Slipfitters, Knuckle Flat Surface, Knuckle Pole
Top and Round Pole Adapters are also available for use
with housings machined with a diagonal hole pattern.
Installation is similar to the Architectural Mounting.
CAUTION: Do not mount any unit below or greater
than 60° above horizontal.
LAMP INSTALLATION
CAUTION
Risk of burn
• Allow lamp/fixture to cool before
handling
Use only lamps specified on nameplate. Observe
lamp manufacturer’s recommendations and restric-
tions on lamp operation, particularly ballast type,
burning position, etc.
LAMP TIGHTNESS — The lamp should be securely inserted to NEMA-EEI specified torque of 35 inch-pounds,
which is best achieved by very firmly tightening to insure
application of sufficient torque. Tightening must be
sufficient to fully depress and load center contact of socket.
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.
Do not remove insulated connectors from wires not
needed for required voltage connection.
Strain relief for incoming power must be provided
in the pole top by the customer.
1. Connect supply leads to internal terminal board as
shown on wiring tag.
(check nameplate for minimum temperature requirement and electrical data).
2. Check luminaire nameplate for ballast type, single or
multivolt, or multiwatt.
IF SINGLE VOLTAGE — All single voltage ballasts are
prewired such that user need only connect the supply
conductors.
IF MULTIVOLT — (120/208/240/277 volts) Connect
the ballast lead with the insulated terminal to the desired
voltage terminal as indicated on the ballast terminal
nameplate.
IF MULTIWATT — Multiwatt ballasts are available in
various combinations of wattage. See wiring instructions on
wiring tag inside the luminaire.
Reattach reflector plate, close door and check for secure
latch engagement. Installation is complete.
PHOTOELECTRIC CONTROL (if option present)
Photoelectric control receptacle should be oriented
before control is installed. Loosen the two holding screws
and rotate receptacle until “North” is directed as near as
possible to true North. Tighten holding screws and install
control.
MAINTENANCE AND CLEANING
It will occasionally be necessary to clean outside of door
glass to maintain light levels. Frequency of cleaning will
depend on ambient dirt levels and minimum light level
which is acceptable to user. Door glass should be washed in
a solution of warm water and any mild, nonabrasive
household detergent, rinsed with clean water and wiped
dry. Should the optical assembly become dirty on inside,
wipe reflector and clean door glass in above manner, and
replace any damaged gasket.
The light output of a luminaire is also dependent on age
of lamp. In applications where light levels are 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.
NOTE: Terminal board will accept supply leads
ranging in size from AWG No. 14 through No. 6
