IMPORTANT SAFETY INFORMATION

For Your Protection, Read Carefully

WARNING: Risk of fire. Do not install
insulation within 3 inches of fixture sides
or wiring compartment, nor above the

heat.

1. Electric current can cause painful
shock or serious injury unless handled
properly. For your safety, always
remember the following:

• Turn off the power supply.

• Ground the fixture to avoid poten-

tial electrical shocks.

• Do not handle an energized fixture

or energize any fixture with wet
hands, when standing on a wet or
damp surface, or in water.

2. Specific safety information concerning
lamps:

• Match wattage of fixture and lamp

exactly.

• Do not remove or insert lamp when

power is on.

• Do not scratch glass or subject lamp

to undue pressure as either may
cause lamp breakage.

• Protect operating lamp from sources

of moisture.

NEW INSTALLATION FOR GRS
Lay-in panel T-bar ceiling:

1. Cut ceiling opening slightly larger
than the outside diameter of the
mounting frame.

2. Position mounting frame through
opening in ceiling. Release clamp­ing latch arms and adjust channel
bars to the correct spacing be­tween T-bar as shown in Figure 1.
Secure channel bars to T-bar by
means of wire ties, screws or by
bending ends onto T-bar as shown
in Figure 2.

3. Once mounting frame has been
secured in structure, adjust the
mounting frame vertically to align
the bottom edge to either flush or
slightly above (1/8" max) the ceiling
line. Secure mounting frame into
position by closing the clamping
latch arm.

4. If additional security is required, a
No. 8 sheet metal screw, wire tie or
wire (not supplied) may be used to
tie the latch arm to the mounting
frame as shown in Figure 1.

5. Remove knockouts on junction box to
feed power supply to fixture as
shown in Figure 4. Supply wire must
meet applicable electrical codes
and be rated for a minimum of 75
Junction box is thru-wire rated for 8­No. 12 AWG conductors (4 in-4 out).

6. Complete necessary wire connec­tions. Snap the door onto the junc-

tion box.

Note 1: For fluorescent applications­Dimming: Make necessary wire

connections per ballast type.
EL and HID F-Can: Allow for 9-1/2” head
space above for ballast maintenance.
Pivot ballast tray onto spacer brackets
as shown in Figure 5. Thermal protector
assembly must be plugged into the
appropriate power supply voltage (120V,
227V or 347V). Snap door onto the
junction box.

Note 2: For incandescent 277V SDT
applications, make sure a minimum of

9-1/2” head space is available for yoke
height.

7. Pull flex through center hole of
bracket as shown in Figure 3.

8. Center mounting bracket in frame
aperture, and loosen screws until

Non-accessible ceiling (plaster, dry-

wall, etc.):

1. Release clamping latch arms and
adjust channel bars to the correct
spacing between joists as shown in
Figure 1.

2. Mounting Channel Bar- Flexible

Wiring Method

Bend ends of channel bars 90° and
adjustment at its lowest point on the
mounting frame. Make sure bottom
of the flange is flush with the bottom
of the joists. Secure mounting frame
into position by closing the clamping
latch arm. Channel bars will accom­ modate mount to joists with vertical
up to 24” O.C. joists

Non-Flexible Wiring Method

If non-flexible wiring methods are
used follow procedure for flexible
wiring methods. Then lower mounting
frame equal to the thickness of the
finished ceiling or slightly above.

3. Remove knockouts on junction box
to feed power supply to fixture.
Supply wire must meet applicable
electrical codes and be rated for a
minimum of 75°C. Junction box is
thru-wire rated for 8-No. 12 AWG
conductors (4 in - 4 out).

4. Complete necessary wire connec-

tions. Snap the door onto junction
box. Note 1. For fluorescent appli-
cations. Dimming- Make necess­ary wire connections per ballast
type. EL HID F-can- Allow for 9-1/2”
head space above for ballast
maintenance. Pivot ballast tray
onto spacer brackets as shown in
Figure 5. Thermal protector assem­bly must be plugged into the
appropriate power supply voltage
(120V, 277V or 347V). Snap door onto

junction box.
Note 2. For incandescent 277V SDT
applications, make a minimum of 9­ 1/2” head space available for yoke

height.

5. Follow steps 6-14 in previous
