INSTALLATION
1. Mount the back box by means of mounting lugs. Install conduit nipple and sealing fittings, to be installed on each
conduit entrance or exit to the enclosure back box in Class I and Class II areas. Thread conduit into sealing fitting
(Note: For Class I areas, the conduit should engage [5] full threads.)
2. The conduit threads should be lubricated with a non-electrical insulating lubricant or pipe joint compound that will
not promote corrosion or chemically attack aluminum.
3. After conduit system has been properly installed, pull the wires and make electrical connections as required. The
electrical circuits and ground continuity should be checked with an instrument approved for the area. Notice:
Connect only copper wire to this device.
4. All conduits entering or leaving the enclosure must be sealed within 18” of the enclosure with listed sealing
fittings. Caution must be taken during installation to be sure that the ground flange flame joints of the cover and
box are not scratched, nicked, or damaged. Before assembly of the cover to the box, the mating ground surfaces
of both the box and cover should be wiped clean to assure that the ground flame joint will be free of all foreign
particles such as lint, dust or dirt.
5. After tightly bolting the cover assembly/assemblies to the enclosure, all box to cover flame joints should be
checked with a 0.0015” thick feeler gauge such that the gauge will not enter the flame path more than 1/8” at any
point.
WIRING
Standard pigtail(flying leads) wiring
We strongly encourage a licensed electrician install this product,in all locations especially in outdoor areas
where weatherproofing may be required. Universal voltage driver permits operation at 600V.
Warning: Check product label for correct input voltage!
Attach supply line wires to the appropriate light fixture wires as shown
in thediagram 
Secure each pair of wires according to the diagram. Utilize a junction box or
similar device and take precautionary steps for weatherproofing all
connections if installed in a location where water may come in contact with the
unit. Ensure the unit is properly grounded and that wiring is done according to
all local and national electrical/building codes.
MAINTENANCE
All moving shafts should be lubricated
occasionally to prevent binding. Only use a
lubricant which is suitable for use with
aluminum or stainless steel. If devices are
to be installed in corrosive areas which will
attack aluminum alloys containing less than
0.4% copper (boxes and covers) and 303
stainless steel (mostly shafts), the device
should be suitably protected from the
corrosive material.
CAUTION: To prevent ignition of
hazardous atmospheres, disconnect from
the supply circuits before opening the
enclosure; keep tightly closed while circuits
are energized.
