IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety precautions should always be followed, including the following:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
1. CAUTION – This fixture provides more than one power supply output source. To reduce the risk of electrical
shock, disconnect both normal and emergency sources by turning off the A.C. branch circuit.
2. CAUTION – This is a sealed unit. Replace the entire unit when necessary.
3. DO NOT USE OUTDOORS. The ETS is for use with grounded, UL Listed, indoor fixtures. Not for use in
heated air outlets or hazardous locations.
4. The ETS requires an unswitched A.C. power source of either 120 or 277 volts. Properly cap the unused
A.C. lead.
5. Do not mount near gas or electric heaters.
6. The ETS should be mounted in locations and at heights where it will not readily be subjected to tampering by
unauthorized personnel.
7. The ETS is compatible with all A.C. magnetic and electronic ballasts.
8. The use of accessory equipment not recommended by the manufacturer may cause an unsafe condition.
9. Do not use this equipment for other than intended use.
10. Install in accordance with the National Electrical Code and local regulations.
11. Installation and servicing should be performed by qualified personnel.
12. Lighting fixture manufacturers, electricians, and end-users need to ensure product system compatibility before
final installation.

INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off.
1. MOUNTING THE ETS
Remove the ballast channel cover. Mount the ETS in the ballast channel at least ½″away from the
A.C. ballast(s).
2. WIRING
Refer to the wiring diagrams on the back page for the appropriate wiring of lamp(s) and ballast. Install
in accordance with the National Electrical Code and local regulations. For additional wiring diagrams
consult Customer Service.
3. INSTALLING THE LED
Recessed Troffer Fixture – Select a convenient location with proper clearance in the ballast cover
and drill or punch a 7/8″hole (1/2″knockout). Insert the 7/8″bushing into the hole. Push the plastic tube
through the bushing. Disconnect the leads from the LED housing and route the leads down the plastic
tube. Reconnect the leads to the housing, observing the proper polarity (Yellow lead to red marked or
positive (+) red tab). Push the entire assembly back into the tube until the lens collar rests against the
plastic tube. The plastic tube should be adjusted so that the LED is within ¼″ of the fixture lens. The
LED must be visible after installation. Refer to Illustration 1.
Strip Fixture – Select a convenient location on the side of the fixture so the LED can be seen after in-
stallation. Allow for proper clearance inside the fixture and drill or punch a ½″ hole. Disconnect the leads
from the LED housing. Push the LED housing into the ½″ hole until it is firmly locked in place. Recon-
nect the leads, observing the proper polarity (Yellow lead to red marked or positive (+) red tab). Refer to
Illustration 2.
4. WIRING THE A.C. INPUT
Refer to wiring diagrams on Page 4 for the proper wiring configuration of the ETS. For wiring diagrams
not shown, consult Customer Service.

OPERATION
Normal Mode –A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended.
Emergency Mode –The A.C. power fails. The ETS senses the A.C. power failure and automatically switches
to the auxiliary generator power. All lamps in the fixture are illuminated at full light output for as long as gen-
erator power is available. When the A.C. power is restored, the ETS switches the system back to the Normal
Mode. See page 1 of the Instruction Manual.
TESTING & MAINTENANCE
The ETS is a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life
Safety Code, outlines the following schedule:
Insure that the LED light is illuminated monthly.
“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”
SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.
