IOTA IIS-35-HE User 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 discon-
necting the unit connector before servicing.
3. The IIS-35-HE requires an unswitched A.C. power source of either 120 or 277 volts.
4. DO NOT USE OUTDOORS. The IIS-35-HE is for use with grounded, UL Listed, damp location rated, indoor
fixtures. Not for use in heated air outlets or hazardous locations.
5. Do not mount near gas or electric heaters.
6. Do not use this equipment for other than its intended use.
7. Not for use with HID loads.
8. The IIS-35-HE should be mounted securely in locations and at heights where it will not readily be subjected
to tampering by unauthorized personnel.
9. The use of accessory equipment not recommended by IOTA Engineering, LLC may cause an unsafe condi-
tion, will void the warranty, and result in non-compliance with UL specifications.
10. The AC voltage rating of this equipment is specified on the product label. Do not connect the IIS-35-HE
equipment to any other voltage.
11. The IIS-35-HE meets CEC requirements for a small battery charger per CEC-400-2015-021-CMF.
12. Suitable for use in damp locations.
13. For use in 0° C minimum, 50° C maximum ambient temperatures.
14. Install in accordance with the National Electrical Code and local regulations.
15. Installation and servicing should be performed by qualified personnel.
16. 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 and the IIS-35-HE unit
connector is disconnected.
1. MOUNTING THE IIS-35-HE
Mount the IIS-35-HE on or adjacent to the fixture in a position that does not interfere with the existing A.C. driver, ballast or
any other hardware. Extend the flex conduit to the junction box or wireway channel and punch a 7/8″hole. Feed the wires
and flex connector down through the hole in the fixture and secure in place with the flex connector nut. An optional T-bar
mounting kit is available to mount the IIS-35-HE above the ceiling tile adjacent to the fixture. Refer to Illustration 1. To order
the optional T-bar mounting kit (part number TBMK-160) contact Customer Service.
When remote mounting, maximum allowable distance between the inverter and fixture is 250 ft. Consult Customer
Service for additional information.
CAUTION: Properly secure the IIS-35-HE in the ceiling grid to insure compliance with local, state, and
federal guidelines regarding ceiling mounted equipment.
2. WIRING
A. CONNECTING THE INVERTER AC INPUT
This is the AC input that charges the inverter battery, therefore it requires an unswitched AC supply. Connect the AC line
wire to the ORG/BLK lead. Connect the WHITE to the AC Neutral. Refer to the Wiring Diagram on Page 4.
B. CONNECTING THE NORMAL AC SWITCHED / UNSWITCHED SUPPLY
This is the AC input that operates the fixture during normal operation. It may be switched or unswitched.
Connect the BLACK lead to the switched or unswitched AC supply. Refer to the Wiring Diagram on Page 4. For Emer-
gency Only (Normally Off) operation, the BLACK lead is not used and should be capped separately.
C. CONNECTING THE INVERTER TO THE AC FIXTURE
Connect the output leads of the IIS-35-HE to the AC fixture. Refer to the Wiring Diagram on Page 4. For additional
wiring diagrams consult Customer Service.
Wire the AC driver/ballast with the lamp(s) in accordance with the manufacturer’s installation instructions.
Note: only emergency fixtures should be present on the load side of the IIS-35-HE. Keep the output neutral isolated
from all other neutrals including the input neutral.
Install in accordance with the National Electrical Code and local regulations.
3. INSTALLING THE THREADED BODY TEST SWITCH (TBTS)
The TBTS test switch and charge indicator is to be installed either within the AC fixture or in a single gang switch
box (not provided) adjacent to the fixture.
Single Switch Box Installation - Cut a single gang switch box into the ceiling adjacent to the fixture. After mount-
ing the switch box, route test accessory leads from the junction box to the switch box via flexible conduit (not pro-
vided). Complete connections within the switch box, observing proper polarity. Refer to Illustration 1.
Integral Fixture Installation - Select a convenient location with proper clearance in the fixture where the test com-
ponents are visible and accessible after installation. Drill or punch a 1/2″hole. Push the TBTS housing into the 1/2″
hole until it is firmly locked in place. Connect the leads, observing the proper polarity. Refer to Illustration 2.
Recessed Troffer Fixture Installation - Select a convenient location with proper clearance in the ballast cover or
exposed wireway 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 leads, observing the
proper polarity (Refer to the Wiring Diagram on Page 4). 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 3.
4. COMPLETING INSTALLATION
INSURE WIRING IS IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE AND LOCAL REGULATIONS.

OPERATION
Normal Mode – A.C. power is present. The A.C. driver/ballast operates the lamp(s) as intended. The IIS-35-HE is in
the standby charging mode. The TBTS will be lit providing a visual indication that the battery is being charged.
Emergency Mode – The A.C. power fails. The IIS-35-HE senses the A.C. power failure and automatically switches to
the Emergency Mode. The fixture is powered by the IIS-35-HE for a minimum of 90 minutes. When the A.C. power is
restored, the IIS-35-HE switches the system back to the Normal Mode and resumes battery charging. See page 1 of
the Instruction Manual.
TESTING & MAINTENANCE
Initial Testing – Allow the unit to charge approximately 1 hour, then conduct a short discharge test. Allow a 24 hour
charge before conducting a full discharge test.
The IIS-35-HE is a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life Safety
Code, outlines the following schedule:
Monthly – Insure that the TBTS light is illuminated. Conduct no less than a 30 second discharge test by depressing
the TBTS. Lamp(s) should operate at full output.
Annually – Insure that the TBTS light is illuminated. Conduct a full 11/2hour discharge test. The unit should operate as
intended for the duration of the test.
“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”
SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.
Consult Customer Service for current warranty information.

A. Once AC Power has been applied, join the IIS-35-HE unit connector.
The TBTS will illuminate indicating the presence of AC power and that the battery is being charged.
B. Attach the appropriate labels adjacent to the TBTS. Annotate Replacement Label with identical manufacturer
part number(s). The Caution and the Replacement labels must be on the fixture in a readily visible location to
anyone attempting to service the fixture.
C. Allow the IIS-35-HE to charge for approximately 1 hour then conduct a short discharge test to confirm proper
operation. To conduct a long-term discharge test, allow the IIS-35-HE to charge for 24 hours. Refer to the
“Operation” section for confirming proper operating performance.
