4. COMPLETING INSTALLATION
A. Energize the AC supply. The Ready (Yellow) Indicator will illuminate and the Inverter On (Green) Indicator will be
off. Mate the install wires on the left side of the unit. The Inverter On (Green) Indicator will illuminate at
this time. The Alarm (Red) Indicator will be out.
B. Operate the Test Switch for approximately 10 seconds. Observe that any emergency fixtures do not go out,
then release the Test Switch.
C. Reinstall the front cover 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-350-U.
3. OPERATION
Normal Mode - AC power is present and operates the fixtures as intended. The IIS-350-U is in the standby charging
mode. The Ready (Yellow) Indicator will be lit providing a visual indication that the unit is in Standby Mode.
Emergency Mode - The AC power fails. The IIS-350-U senses the AC power failure and automatically switches to
the Emergency Mode. All fixtures connected to the
IIS-350-U will be illuminated for a minimum of 90 minutes. When
the AC power is restored, the IIS-350-U switches the system back to the Normal Mode and resumes battery charg-
ing. See page 1 of the instruction manual for important operational safeguards and requirements.
4. TESTING
1) To test the equipment, depress the test switch. The Ready (Yellow) Indicator will go off. The designated fixtures
will stay on and the Inverter On (Green) Indicator will remain lit.
2) Release the Test Switch. The Ready (Yellow) Indicator will come on.
The equipment is supplied with an automatic solid state charger designed to fully recharge the battery within 24
hours after AC power is restored, and then maintain the battery in a fully charged state. Allow the battery to charge
for a minimum of 24 hours after installation or power failure before conducting a 90 minute discharge test. The Life
Safety Code and the Authorities Having Jurisdiction require that this test be performed on an annual basis.
5. MAINTENANCE
1. Alarm Indicator - Safety features within the IIS-350-U will force the unit to shut down under certain conditions.
The red alarm indicator on the IIS-350-U will flash and the unit will shutdown in the event of over-voltage, low
voltage, over-temperature, or system overload. In the event of a shutdown, contact Customer Service to trouble-
shoot for possible causes.
2. CAUTION: Always turn off the AC supply to the equipment, unmate the install wires and disconnect the battery
before servicing. Only qualified service technicians should service this equipment. The use of parts supplied by
other than IOTA Engineering, LLC may result in an unsafe condition, equipment failure and will void the warranty.
3. 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.
