LUMINAIRE INSTALLATION
NOTE: Multiple luminaire installation can consist of Non-Emergency
Driver LS luminaires with Emergency Driver LS luminaire. An additional
2 -wire power feed is needed for the emergency driver luminaire. Refer to
non emergency LS luminaire installation sheet for electrical wiring.
STEP 1:
Remove the lens/ frame assembly from the housing by pulling up on the
three pull tabs. After releasing the tabs, release latches along length
of luminaire by pressing on designated areas of base and pull top lens
frame assembly away from base. Pull tabs can be discarded once lens/
frame assembly is removed. If the lens/frame needs to be removed in the
future, once pull tabs have been discarded, then use a non-marring tool
or by hand and release the rivet-catch on each end of the luminaire. After
releasing rivet-catches, (See Figure 1, 2, and to the righ
NOTE: The lens and metal lens frame is a single assembly and does not

ELECTRICAL CONNECTIONS-
NOTE: The emergency driver must be fed
from the same branch as the AC Driver.
STEP 1:
Using customer supplied 90°C minimum rated wire
connectors, make the following electrical connections:
a. Connect the black luminaire lead to
the unswitched voltage supply lead.
b. Connect the white/red luminaire
lead to the supply switched hot.
c. Connect white luminaire lead to
the neutral supply lead.
d. Connect ground green/yellow wire
lead to the supply ground lead.
e. If 0/1-10V Dimming is used, connect
the violet lead to the supply positive
dimming lead. If dimming is not being
used ensure to cap off the violet lead.
f. If 0/1-10V Dimming is used, connect
the grey lead to the supply negative
dimming lead. If dimming is not being
used ensure to cap off the grey lead.
STEP 2:
Locate the two red leads coming off of the Emergency
Driver and connect them using supplied connector.

STEP 4:
Bring customer supply wires into luminaire through the wiring
knockouts on the backside (E) or on the end caps and make electrical
connections per “ELECTRICAL CONNECTION” section. See Figure 3.
NOTE: When connecting multiple luminaires together bring leads from
adjoining luminaire into first luminaire through the end cap wiring
knockouts and make wiring connections per electrical code. See
Figure 4.
NOTE: If dimming is an option make electrical connection for dimming
in the dimming compartment. See Figure 4.
STEP 5:
Reattach lens and metal lens frame assembly to luminaire base by
connecting the plug together shown in Figure 2 and carefully push and
metal lens frame assembly up into the base until it snaps in place.
EMERGENCY DRIVER CHECK
NOTE: For short-term testing of the emergency function, the battery
must be charged for at least one hour. The emergency driver must be
charged for at least 24 hours before conducting a long-term test.
STEP 1:
When AC power is applied, the charging indicator light is illuminated,
indicating the battery is being charged. When power fails, the
emergency driver automatically switches to emergency power,
operating the LED array. When AC power is restored, the emergency
driver returns to the charging mode.
STEP 2:
Although no routine maintenance is required to keep the emergency
driver functional, it should be checked periodically to ensure that it is
working. The following schedule is recommended:
• Visually inspect the charging indicator light monthly. It should be
illuminated.
• Test the emergency operation of the fixture at 30-day intervals
for a minimum of 30 seconds. When the test switch is depressed,
the LED array should operate.
• Conduct a 90-minute discharge test once a year. The LED array
should operate for at least 90 minutes.
If the luminaire fails any of these checks, consult service personnel.
REFER ANY SERVICING INDICATED BY THESE CHECKS TO
QUALIFIED PERSONNEL
EMERGENCY DRIVER AND AC DRIVER MUST BE FED FROM THE
SAME BRANCH CIRCUIT
