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 ﬁnal installation.

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.

OPERATION

Normal Mode – A.C. power is present. The A.C. driver or ballast operates the lamp(s) as intended. The ETS-STEP allows operation of the luminaire at the desired dimmed setting by supplying the step-dimming contacts on the A.C. Driver in accordance with the local control devices.

Emergency Mode switches to the auxiliary power. The ETS-STEP Dimming Relay supplies all step-dimming contacts on the A.C. ballast/driver, regardless of the position of the local control devices, forcing the luminaire to operate at full lumen output. All lamps in the ﬁxture are illuminated at full light output for as long as auxiliary power is available. When the A.C. power is restored, the ETS-STEP switches the system back to the Normal Mode. See page 1 of the Instruction Manual.

– The A.C. power fails. The ETS-STEP senses the A.C. power failure and automatically

TESTING & MAINTENANCE

The ETS-STEP is a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life Safety Code, outlines the following schedule:

Insure that the A.C. Indicator 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.
