Introduction
Congratulations on selecting one of the fine products from the leader in power-protection
technology. Our wide product offering includes Uninterruptible Power Systems (UPS), power
conditioners, automatic voltage regulators, and specialty transformers (e.g., computer-grade,
medical-grade). Since 1972, the manufacturer has shipped many of these fine products to
discerning customers worldwide for use on sensitive equipment and critical applications.
The Single-Phase Lighting Inverter is a self-contained unit that provides backup power for
fluorescent and incandescent lighting sources such as overhead fixtures and exit signs. If a
brownout or power outage occurs, the inverter provides 90 minutes of lighting power to
ensure a safe building evacuation. OnLine pulse-width modulation (PWM) handles the
switchover from utility power to battery power automatically, without interruption or manual
intervention. Convection cooling allows the inverter to operate virtually silently.

2.1 Product Description
The Single-Phase Lighting Inverter is manufactured to provide critical power for lighting
during a power outage. The Lighting Inverter meets or exceeds the life safety codes of
UL924 and UL1778. These codes were established to allow emergency lighting inverters to
provide critical power to the lighting circuits during a power failure.
If input power to the inverter is lost during a power outage, the system draws clean sine
wave power automatically from its internal battery supply without any interruption. Power is
provided for 90 minutes, sufficient time for safe and orderly evacuation from the facility.
An optional Input or output or both transformer(s) allows a 277V input or output voltage unit.
The internal valve-regulated lead-acid (VRLA) maintenance-free batteries provide 90
minutes of backup power. When input power is restored, the Lighting Inverter resumes
normal operation automatically and begins recharging the batteries immediately.
An optional internal bypass circuit maintains power to the load in case an internal unit failure
occurs. Comprehensive monitoring capabilities include a Liquid Crystal Display (LCD) panel
and five dry relay contacts for remote monitoring.

2.2 Product Main Features
The Single-Phase double conversion on-line Emergency Lighting Inverter uninterruptable,
clean, Single-Phase power to your critical systems while keeping batteries continuously
charged and providing a back-up in the event of a utility power failure.
If a power failure lasts longer than the rated UPS backup time, your UPS will shut down
systematically, avoiding battery discharge. As soon as utility power is restored, the UPS
will automatically switch to utility power and start recharging the batteries.
As shown in the Single Line diagram, Figure 2-1
•An input filter reduces transients on the mains.
•To maintain a full battery charge, AC power is rectified and regulated in the rectifier
feeding power to the inverter and battery converter.
•DC power is converted to AC in the inverter passing it on to the load.
•Power is maintained from the battery during power failure. The converter increases
the voltage to the inverter.

2.2.1 Efficiency Optimizer Function
The Efficiency Optimizer Function is a new feature of your UPS that adds cost-effectiveness,
provides minimal power loss, and reduced power consumption. Alternating between bypass
and on-line modes is achieved automatically and in accordance with the conditions of the
utility power to obtain the greatest efficiency, on-line mode may function during times of
intermittent utility power availability and bypass mode when power flows smoothly.
Irregularities can be detected in less than a second, and on-line mode is reactivated
immediately. Switching back to online mode occurs when the input voltage exceeds ±10% of
nominal (±15% selectable) when the input frequency exceeds ±3Hz of nominal or when no
input line voltage is detected.
An available option allows default operation in the on-line mode. Bypass can be activated
from the LCD panel, though on-line mode can be run permanently if preferred.
2.2.2 Normal Operation:
There are two main loops when the AC utility is Normal.
•The AC loop
The AC output power comes from the AC utility input and passes through the AC/DC
rectifier, DC/AC inverter, and static switch to support power to the load.
•Battery charging loop
The battery charging voltage comes from the AC utility input and is converted by the AC/DC
charger to support battery charging power.

Chapter 2. Overview
105-MAN Page 14 of 58
2.2.3 AC Utility failure:
The AC output power comes from the battery and passes through the DC/AC Inverter,
DC/AC Inverter, and the Static Switch to provide power to the load.
The battery charging path is from the AC utility input to the AC/DC Charger to charge the
battery.
2.2.4 Bypass Enable:
Under the Following Conditions, the bypass will be enabled:
1. Overload
2. Inverter failure
3. Over temperature
4. DC bus failure

Chapter 2. Overview
105-MAN Page 15 of 58
2.2.5 Free Run Mode
The UPS operates in free-run mode when the input frequency is outside of the selected
input frequency range. In free-run mode, the output frequency does not match the input
frequency. When starting the UPS, the frequency regulation detected is 50 or 60 Hz ±0.25Hz
2.2.6 Diagnostic tests
When you start the UPS, a diagnostic test is automatically executed that checks the
electronics and battery and reports any faults on the LCD screen.
An advanced battery management system always monitors the conditions of the batteries,
sends a warning if replacement is needed, or every 30 days of normal mode operation, a
battery discharge test is automatically performed, and any faults are reported on the LCD
screen.
Diagnostic tests can be performed manually from the front panel at any time except during
the first 24 hours after startup while the UPS is in charging mode.

4.1 Delivery Space Requirements
The following figures show the dimensions of the system cabinets as well as key
components used for cable access and mounting.
Verify that the delivery area, the destination, and the path between them meet the standard
delivery clearance and weight requirements of the system.
The delivery area must provide enough space and floor strength to support the packaged
equipment cartons for the system. Doorways and hallways must provide enough clearance
to move the equipment safely from the delivery area to the destination. Permanent
obstructions such as pillars or narrow doorways can cause equipment damage. If necessary,
plan for the removal of walls or doors.
Verify that all floors, stairs, and elevators you use when moving the system to its destination
can support the weight and size of the equipment. Failure to do so could damage the
equipment or your site.

Chapter 4. Installation
105-MAN Page 20 of 58
4.2 Site Considerations
Planning the proper location and layout of the system prior to installing it is essential for
successful operation. To ensure normal operation and to avoid unnecessary maintenance,
plan your site configuration and prepare your site before installation.
The system is designed for indoor installation and meets NEMA specifications for operating
temperature, humidity, and utility voltage. The system enclosures are rugged and corrosion-
resistant.
All servicing is performed through the front of the unit; therefore, leave sufficient room in the
front of the unit for service access.
The following precautions will help you plan an acceptable operating environment for the
system:
•Select a flat location that is clean, with no dust or exposure to direct sunlight or
vibrations. The location should provide a sturdy, level surface that can support the
system. Avoid locations with inclined floors.
•The location should not be prone to variations in temperature and humidity or be
close to strong magnetic fields or a device that generates electric noise.
•The unit should not place the system next to, on top of, or below any device that
generates heat or will block the free flow of air through the system’s ventilation
slots.
•The Lighting Inverter cabinets provide cable and conduit openings on the top and
sides of the cabinet. Be sure these areas are not blocked and can be easily
accessed to expedite installation.
•Electrical equipment generates heat. Ambient air temperature might not be
adequate to cool equipment to acceptable operating temperatures without adequate
circulation. Ensure that the room in which the system will operate has adequate air
circulation.
Caution: Always follow proper ESD-prevention procedures to avoid damage to
equipment. Damage from static discharge can cause immediate or intermittent
equipment failure.
Caution: For sites with a Generator and Automatic Transfer Switch (ATS) in
conjunction with the unit, make sure the ATS has an open transition with a
minimum 20 milli-seconds transfer time (gap) in both directions
