CAUTION: Before proceeding to Wiring Step 3, make sure that all unused wires are properly capped. Failure
to do so may result in an unsafe condition and equipment failure.
DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.
3. CONNECTING THE BATTERIES
Use only battery part number F741250003 with the unit. See Page 1 of this instruction manual.
A. Retaining brackets are provided. The batteries MUST be secured in the IIS-125. Do not leave the batteries
loose or unsecured within the unit.
B. Connect the batteries by plugging the connector into the receptacle on the PCB. If the batteries are not provided
with a connector, the PCB is equipped with Red and Black wires with ring terminals. Wire the Red wires to the
Positive terminals and the Black wires to the Negative terminals. Torque hardware to 33 in/lbs.
Failure to connect or secure the batteries properly will result in equipment failure, an unsafe condition,
and will void the warranty.
NOTE: The emergency indicator lights will not illuminate at this time.
4. COMPLETING INSTALLATION
A. Energize the AC supply. Only the Ready (Yellow) Indicator and the Charging (Red) Indicator will illuminate.
B. Operate the Test Switch for approximately 10 seconds. Observe that any emergency fixtures do not go out, that
the Inverter On (Green) Indicator comes on, and that any normally off fixtures come on. Release the Test Switch.
Normally Off fixtures and the Inverter On (Green) Indicator will extinguish. Normally On, emergency, and any
switched fixtures will return to their normal operating mode.
C. Properly re-install the cover of the IIS-125 using all the original hardware.
D. Affix red “EMERGENCY CIRCUIT” label (provided) to the panelboard dead front cover near the circuit breaker
feeding the IIS-125.
3. OPERATION
Normal Mode - AC power is present and operates the fixtures as intended. The IIS-125 is in the standby charging mode.
The Ready (Yellow) Indicator and Charging (Red) Indicator will be lit providing a visual indication that the unit is charging.
Emergency Mode - The AC power fails. The IIS-125 senses the AC power failure and automatically switches to
the Emergency Mode. All fixtures, including Normally Off or switched off fixtures, connected to the
IIS-125 will be
illuminated for the duration required by national safety codes (minimum 90 minutes in US, minimum 30 minutes in
Canada). When the AC power is restored, the
IIS-125 switches the system back to the Normal Mode and resumes
battery charging. See page 1 of this Instruction Manual.
4. TESTING
1) To test the equipment, depress the test switch. The Ready (Yellow) Indicator will go off. The designated fixtures will either
illuminate if they were off or will stay on if they were normally illuminated. The Inverter On (Green) Indicator will come on.
2) Release the Test Switch. The Ready (Yellow) Indicator will come on. Normally Off emergency fixtures will extinguish.
The equipment is supplied with an automatic solid state charger designed to fully recharge the batteries within 48
hours after AC power is restored, and then maintain the batteries in a fully charged state. Allow the batteries to charge
for a minimum of 48 hours after installation or power failure before conducting a prolonged discharge test. Monthly and
annual testing should be performed in accordance with NFPA 101, local, state or municipal code requirements.
“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”
5. MAINTENANCE
1) CAUTION: Always turn off the AC supply to the equipment, and disconnect the battery before servicing. Only
qualified service technicians should service this equipment. The use of parts supplied by other than IOTA Engi-
neering, LLC may result in an unsafe condition, equipment failure and will void the warranty.
2) BATTERY - The battery supplied in this equipment is a high quality maintenance-free Valve Regulated Lead Acid
design. It requires no maintenance and when installed in an ambient temperature of 20°-30° C (68°-86° F) its life
expectancy is 8 to 10 years. However, as stated above, the equipment must be tested for 90 minutes a minimum
of once per year. When the battery will no longer operate the load for 90 minutes it must be replaced. Replace
only with IOTA Engineering, LLC supplied parts. Dispose or recycle the lead-acid battery properly.
