INSTRUCTION MANUAL

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-STEP is for use with grounded, UL Listed, indoor fixtures. Not for use in
heated air outlets or hazardous locations.

FOR STEP DIMMING

SERIES ALCR for 3A CIRCUIT

4. The ETS-STEP 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-STEP should be mounted in locations and at heights where it will not readily be subjected to tamper
ing by unauthorized personnel.

7. The ETS-STEP is compatible with all A.C. magnetic and electronic ballasts and drivers.

8. The ETS-STEP is for use in step-dimming applications and not designed for use with 0-10 volt dimming
controls. May be suitable for use in some 3-wire dimming applications. Contact Customer Service for more
information.

9. The use of accessory equipment not recommended by the manufacturer may cause an unsafe condition.

10. Do not use this equipment for other than intended use.

11. Install in accordance with the National Electrical Code and local regulations.

12. Installation and servicing should be performed by qualified personnel.

13. Lighting fixture manufacturers, electricians, and end-users need to ensure product system compatibility before

CAUTION: Before installing, make certain the A.C. power is off.

1. MOUNTING THE ETS-STEP
Remove the driver channel cover. Mount the ETS-STEP in the ballast/driver channel at least ½″ away

from the A.C. ballast/driver(s).

2. WIRING

Refer to the wiring diagrams on the back page for the appropriate wiring of ballast/driver. Install in ac-

cordance with the National Electrical Code and local regulations. For additional wiring diagrams consult
Customer Service.

3. INSTALLING THE AC INDICATOR

Recessed Troffer Fixture – Select a convenient location with proper clearance in the ballast/driver

channel 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 A.C. Indicator 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 A.C. Indicator is
within ¼″ of the fixture lens. The A.C. Indicator must be visible after installation. Refer to Illustration 1.

Strip Fixture – Select a convenient location on the side of the fixture so the A.C. Indicator can be

seen after installation. Allow for proper clearance inside the fixture and drill or punch a ½″ hole. Discon­nect the leads from the A.C. Indicator housing. Push the A.C. Indicator housing into the ½″ hole until it
is firmly locked in place. Reconnect the leads, observing the proper polarity (Yellow lead to red marked
or positive (+) red tab). Refer to Illustration 2.
