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 – To prevent electrical shock, do not mate unit connector until installation is complete and A.C. power
is supplied to the unit.

2. 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 and by disconnect­ing the unit connector.

3. CAUTION – This is a sealed unit. The integral, high temperature Ni-Cad battery is not replaceable. Replace the
entire unit when necessary and recycle or dispose of the nickel-cadmium battery properly.

4. DO NOT USE OUTDOORS. The I-320 is for use with grounded, UL Listed, damp location rated, indoor fixtures.
Not for use in heated air outlets or hazardous locations.

5. The I-320 requires an unswitched A.C. power source of either 120 or 277 volts. Properly cap the unused A.C. lead.

6. When the I-320 is installed on the same branch circuit, refer to Illustration 3, Figures A and B for input wiring. When
installed on separate branch circuits, refer to Illustration 3, Figures C and D for input wiring. Per NEC, the I-320 and
A.C. ballast must be on the same panel board.

7. Do not mount near gas or electric heaters.

8. The I-320 should be mounted in locations and at heights where it will not readily be subjected to tampering by
unauthorized personnel.

9. The I-320 will cold strike and operate one 14W through 54W T5 or 2´-4´ T8 instant start or rapid start fluorescent
lamp, including energy saving and 4-pin compact lamps for 90 minutes.

10. The I-320 is compatible with most A.C. ballasts (including multiple lamp) as follows:
Magnetic ballasts – one lamp emergency operation.
Electronic ballasts – one lamp emergency operation.

11. Suitable for use in damp locations.

12. For use in 0° C minimum, 50° C maximum ambient temperatures.

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

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

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

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

17. 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 and the I-320 unit connector is disconnected.

1. LAMPS OPERATED

The I-320 can be used with most 2′–4′ lamps. Refer

to the chart on the right for the type of lamp
operated in emergency mode. Contact Customer Ser­vice for answers about specific lamps.

*The 6″ violet leads provide the lamp selection option.
The unit is shipped from the factory with the leads
disconnected and capped. When used with particular
lamp types, violet leads should be connected to one
another. Refer to chart for lamp selection options.

2. MOUNTING THE I-320

Remove the ballast channel cover. Mount the I-320 in the ballast channel at least 1/2″ away from the A.C. ballast(s).

When battery packs are remote mounted, consult Customer Service for the maximum allowable distance between
the battery pack and the lamp.

3. 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.

4. INSTALLING THE THREADED BODY TEST SWITCH (TBTS)

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.
Route the leads of the TBTS through the plastic tube. Connect the LED wires from the unit to the TBTS (Red/Black
or Red w/tag to Red, White/Red to White). 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 TBTS is within ¼″ of the fixture lens. The
TBTS must be visible after installation. Refer to Illustration 1.

Strip Fixture – Select a convenient location on the fixture so the TBTS can be seen after installation. Allow for

proper clearance inside the fixture and drill or punch a 1/2″ hole. Remove the nut from the TBTS. Push the TBTS
housing into the 1/2″ hole and secure with the nut. Connect the LED wires from the unit to the TBTS (Red/Black or
Red w/tag to Red, White/Red to White). Refer to Illustration 2.

ATTENTION: Only connect the I-320 to the TBTS LED supplied with the unit. The LED must be replaced
when replacing the unit.

5. WIRING THE A.C. INPUT

A. When the I-320 is installed on the same branch circuit, refer to Illustration 3, Figures A and B for input wiring.

When installed on separate branch circuits, refer to Illustration 3, Figures C and D for input wiring. Per NEC, the
I-320 and A.C. ballast must be on the same panel board.

B. The I-320 requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when used with

C. Refer to the wiring diagrams on the back page for the proper wiring. For wiring diagrams of ballasts not shown,

switched fixtures, the I-320 input must be wired ahead of the switch. Refer to Illustration 3 for switched and un­ switched fixture wiring diagrams.
