Installation Instructions for MD6xT6, MD6xT4, MD6CPxT6 and MD6CPxT4
Commercial Recessed Housings
CAUTION: To avoid possible electrical shock, be sure that power supply is turned off before installing or servicing this
fixture.
CAUTION: Metal halide lamps have arc tubes that operate at extremely high temperatures and may shatter unexpectedly
as a result of misapplication, system failure or internal factors. This violent failure could cause extremely hot glass
and lamp parts to discharge into the surrounding environment, creating a risk of personal injury, fire or property
damage. Therefore, it is incumbent on the user to use common sense and good judgment in anticipation of these
potential violent failures. Never use or operate this fixture without safety glass or lens properly installed and secured in
place.
Reduction of Risk
The potential of violent failure can be significantly reduced by relamping at or before the rated end of life. In applications
where the lamps burn continuously, the lamps should be turned off for a period of 15 minutes at least once per week
which will cause lamps nearing their end of life to fail passively upon relighting. Careful adherence to the above
precautions may not eliminate all possible risks associated with the use of Metal Halide lamps, but it will reduce the
likelihood of personal injury or property damage.
Rough-In Mounting
•This fixture should be supported by main runners or
other structure that is capable of supporting fixture
weight of 17lbs.
•The junction box will accept both ½” and ¾” trade size
metal conduit.
•Review fixture labeling to make sure it is rated for the
voltage installation being used.
•The housing is designed for installation where it will
not come in contact with insulation. Thermal insulation
must be kept a minimum of three inches (3”) away
from the housing sides, top and junction box.
•This housing/trim is designed to be used with T6/T4.5
Ceramic Metal Halide lamps for the specified wattages
only. These lamps can cause serious skin burn and
eye inflammation from shortwave ultraviolet radiation if the envelope of the lamp is broken or punctured.
Risk Of Fire
Supply conductors (power
wires) connecting the fixture
must be rated minimum
90°C. If uncertain, consult an
electrician.
Risk Of Electrical Shock
Disconnect power at fuse or
circuit breaker before
installing or servicing.
Risk Of Fire.
Do not install insulation
within 3 inches (76 mm) of
any part of the fixture or in a
way that may entrap heat.

Step 1. Install fixture into ceiling cavity using ½” electrical conduit, ¾” channel, 1½” channel or  “ x ½” bar stock as
mounting rails (furnished by others) by inserting them into hanger brackets at both ends of the fixture as shown.
Step 2. Secure mounting rails to support structures.
Step 3. Adjust fixture so bottom of plaster ring is flush with finished ceiling line, using screws securing hanger brackets.
Hanger bracket is reversible for a total adjustment of 5”.
Electrical Connection
CAUTION: Make certain no bare wires are exposed outside of wire nut connectors.
Step 4. Provide electrical service according to the “National Electrical Code” or your local electrical code to the junction
box (located on the plaster frame). Supply wire insulation must be rated for at least 90° C. The junction box is
also rated for a maximum of 12 No. 12 AWG Branch Circuit conductors suitable for at least 90°C.
Step 5. Remove junction box cover.
Step 6. Remove appropriate round pryout and connect conduit to junction box with proper connector (not included).
Step 7. Connect supply lead wires to junction box lead wires (line, neutral and ground) in fixture using properly sized
wire nuts (not included). Be careful not to leave any bare conductors outside of the wire nut connectors.
Step 8. 120V or 277V AC Supply: Connect white to white, black to black and green (from electrical service) to the bare
copper wire in the junction box. See the appropriate wiring diagram for more detail.
Place all connections and excess wiring into the junction box and replace cover.

Distribution Selection & Trim Installation
Step 1. Install the proper lamp type and wattage into the socket. Make sure the new lamp does not have any
fingerprints, dust, lint, etc.
NOTE: The lamp-socket assembly is installed onto the trim in one of three possible positions. These are labeled
Narrow, Medium and Wide. The selected position determines the light distribution from the fixture.
Step 2. As shown in figure at right, the trim assembly includes
six plastic lockout inserts. Remove and discard the
two lockouts from the desired distribution positions.
For example, if a Medium distribution is desired,
remove the two lockouts closest to the “Medium”
labels.
NOTE: It is intended that the remaining plastic lockouts remain
in place. This will help avoid any inadvertent
distribution changes during re-lamping in the future.
Step 3. Secure the lamp-socket assembly in the desired
distribution position with the two thumbscrews.
Step 4. Install the trim into the housing. The trim’s torsion
springs pass through slots in torsion spring receivers
inside the housing.

Lamping Information
•The electronic ballast has a very important shutdown timing feature that turns off the ballast output after time
periods ranging from 2 minutes up to 30 minutes if a lamp does not start or operate properly or if the fixture wiring
is improper. For proper system diagnosis and at lamp replacement time, the INPUT POWER TO THE BALLAST
MUST BE RESET (turn power off, wait 10 seconds, turn power back on) to start a new lamp.
•Take proper care in handling and disposing of the old lamp. Do not touch glass bulb with bare hands.
•Lamp contains Mercury. Manage in accordance with disposal laws. See www.lamprecycle.org or 1-866-666-
6850.
