SAVE THESE INSTRUCTIONS – This manual contains important Instructions that must be followed during
the installation and maintenance of the UPS.

• The UPS has its own internal energy source (battery). A voltage may be present at the output
terminals even when no AC input power is available.

• This UPS is equipped with an EMI filter. To prevent potential leakage current hazard, ensure that the
AC main supply is securely grounded.

• Make sure that the AC utility outlet is correctly grounded.

• Make sure that the input voltage to the UPS matches the rating on its name plate. Use a certified
input power cable with the correct plugs and sockets for the appropriate voltage system.

• Install the UPS indoors only as it is not designed for outdoor use. Install in a temperature-controlled
indoor area free of conductive contaminants

• To prevent the UPS from overheating, keep all ventilation openings unobstructed. Do not place
anything on top of the UPS. Keep the UPS rear panel at least 20 cm away from the wall or other
objects.

• Units are considered acceptable for use in a maximum ambient of 40°C. Make sure the UPS is
installed in an appropriate environment—0 to 40ºC (32 to 104ºF) ambient temperature, and 30 to
90% relative humidity (non-condensing).

• Do not install the UPS in direct sunlight. Failure of the batteries under these conditions may void the
warranty.

• Do not install in a inflammable or hazardous environment.

• Dusty, corrosive, or salty environments can damage the UPS.

• Install the UPS away from objects that give off excessive heat and areas that are excessively wet.

• Do not install the UPS in an environment with sparks, smoke or gas. Not for use in a computer room
as defined in the Standard for the Protection of Electronic Computer/Data processing Equipment,
ANSI/NFPA 75.

• The entrance of liquids or foreign objects into the UPS will void the warranty.

• The battery will gradually discharge if the system is unused for extended periods.

• If unused, recharge the UPS every 2 to 3 months. Neglecting to do so will void the warranty. The
batteries charge automatically and are kept in good condition if the UPS is installed and used.

• This UPS supports electronic equipment in offices, telecommunications, process control, medical
and security applications. Only authorized personnel must install the UPS in the following locations:

• Medical applications directly related to human life

• Elevators, metro (subway) system or any other equipment related to human safety

• Public security system or critical computer systems

• Always switch off the UPS and disconnect the batteries before relocating the UPS. It may cause
electrical shocks if the output is not completely switched off.

• Do not open the UPS—there are no serviceable parts inside. Opening the UPS will void the warranty.

• Do not repair the UPS yourself Contact your local supplier. Opening the UPS will void the warranty.

1.2  Storage Instructions

Store the UPS in a location where the temperature ranges between -15ºC (+5ºF) to 40ºC (104ºF).

For extended storage in moderate climates, charge the batteries for 12 hours every 3 months. Connect
the UPS to the utility supply and switch on the input breaker located at UPS rear panel. Repeat this pro­cedure every 2 months if the ambient storage temperature is above 30ºC (86ºF).

2.  Introduction

2.1  General Characteristics

True double conversion online technology provides uninterrupted output to your critical device with
stable, regulated, transient-free, pure sine wave AC power.

• High-efficiency pulse-width modulation (PWM) sine-wave topology yields excellent overall
performance. The output is capable of handling high crest factor and high inrush current loads.

• User-friendly plug and play design allows hassle-free installation. All units up to 3kVA are supplied
with input cables and output sockets as standard.

• Built-in maintenance-free sealed-type battery minimizes after-sales service.

• Automatic overload protection switches the output from inverter mode to bypass mode if the load
increases to 105 to 120% of full load for 30 seconds and automatically enables inverter mode when
the overload condition is removed.

• If the output is short-circuited, the UPS locks automatically, provides visual & audible alarms and
cuts the output supply until the short circuit situation is resolved.

• The USB / RS232 interface provides convenient plug and play with other IT products powered by the
UPS.

2.2  Special Features

• High frequency transformer-less technology with a rack/tower convertible enclosure facilitates
integration of the UPS even in difficult environments with space constraints.

• This UPS is equipped with fully digitized control logic for greater functionality and an enhanced
high level of power protection. Digital signal processing (DSP) enhances the UPS communication
capability by providing the flexibility for easy remote control and monitoring.

• Wide input voltage tolerance from 60V to 144V (120V version) or 120V to 288V (230V version) allows
under-voltage or over-voltage correction without unnecessary battery drain which helps to extend
the battery life span.

• DC-start function ensures start-up of the UPS even during power outages.

• Revolutionary battery management circuit analyzes battery discharging status to adjust the battery
cut-off point and extend the batteries’ life span.

• Active Power Factor Correction (PFC) control function constantly maintains the UPS Input Power
Factor (PF) at > 0.99 for energy efficiency.

• Selectable Bypass input voltage tolerance (Sensitivity low/high) prevents the supply of under or over
voltage to the loads in Bypass mode. The selectable Voltage ranges are:

• Sensitivity Low: 90/ 180 to 130/ 260V

• Sensitivity High: 97/ 194 to 130/ 260V

• Large number of selectable output voltages (100/ 110/ 115/ 120/ 127 V or 200/ 208 /220 /230 /240 V)
meet the requirements of various voltage systems.

• The UPS complies with various stringent international standards for Electromagnetic Interference &
Compatability (EMI & EMC).

6.  UPS Maintenance

6.1  Battery Replacement Precautions

This UPS is intended for use with a maximum of one extension battery pack. Refer to Section 6.2 for the
installation procedure.

The following precautions apply when replacing batteries in a SERVICE ACCESS AREA:

• Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions.

• There is a risk of explosion if a battery is replaced by an incorrect type. When replacing batteries,
replace with the same type and number of batteries or battery packs.

CAUTION!

Do not dispose of batteries in a re. The batteries may explode. Dispose of used batter­ies according to the instructions.

CAUTION!

Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes.
It may be toxic.

6.2  Battery Replacement

When the UPS is started up or a self-test is executed, the battery replacement symbol on the LCD panel
may appear because of a weak or dead battery.

1. If the battery replacement symbol on the LCD panel appears, charge the UPS for at least 8 to 10
hours. The symbol should disappear after the self-test function has executed.

2. If the battery replacement symbol stays on after charging, unscrew the battery cover and replace the
battery as shown in the following sections.

CAUTION!

A battery can present a risk of electrical shock and high short circuit current. The fol­lowing precautions should be observed when working on batteries:

a. Remove watches, rings, or other metal objects.

b.  Use tools with insu lated handles.

c.  Wear rubber gloves and boots.

d.  Do not lay tools or metal parts on top of batteries.

e.  Disconnect charging source prior to connecting or disconnec ting battery terminals.

f.  Determine if the battery is inad vertently grounded. If inadver tently grounded, remove source from ground.  

Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can 
be reduced if such grounds are removed during installation and maintenance (applicable to equipme nt not 
having a ground ed supply circuit).

CAUTION!

The UPS will not provide any output power if the start-up procedure has not completed
properly even though the input power cord is connected to the wall receptacle.

A-1  Theory of Operations

The UPS System Block Diagram below illustrates the true on-line double conversion architecture of the
UPS system.

The major modules consist of the following:

• AC to DC power converter (rectifier) with a Power Factor Correction

• DC to AC power high frequency inverter

• Isolated intelligent battery charger

• Bank of stationary maintenance-free batteries

• DC to DC converter

• Static bypass loop

• Input and output EMI filters

The following table summarizes the UPS operating modes during various utility AC power conditions:

Utility Conditions

Utility normal

Utility abnormal
(under or over
voltage) or absent

Utility abnormal or
absent, battery low

The following sections describe the operation of the UPS under different conditions.

UPS Operating Modes

Rectier converts AC to DC. Battery charges. Inverter
converts DC to AC and supplies the loads with clean, stable
power.

Rectier and charger stop operating. Battery discharges
via DC-DC boost circuit and supplies the inverter. Loads
continue to receive supply from the inverter. Buzzer beeps.

Rectier and charger stop operating. Battery discharges via

A-2  Utility is Normal

When the utility voltage is normal, the AC power is rectified to DC power, which is then fed into the in­verter. The charger is switched to charge the batteries. The inverter transforms the DC power to clean AC
power that supplies the loads. The , ,and LEDs are illuminated.

A-3  Utility Power is Abnormal/Absent

The working principle of the UPS when the utility power is abnormal is illustrated below:When the utility
power is abnormal (under voltage, over voltage or absent), the UPS converts battery power to AC power
through the DC-DC and DC-AC inverter. It also disables the AC-DC and charger sections. This happens
instantaneously as the abnormality is detected.

1. When utility power returns to normal, the UPS switches to normal mode as explained in the previous
section.

2. During a utility outage, the figure above illustrated the operation of the UPS. When the batteries are
depleted, the buzzer beeps continuously until the unit is shutdown. The UPS low battery protection
shuts off the output after a preset threshold to avoid over-draining the batteries. The
low)& (battery abnormal) symbols appear on the LCD until the UPS is completely shut off. The
UPS re-starts automatically when the utility is restored.

A-4  Overload Condition

1. Most electronic and IT equipment draw an inrush current when turned on. The amplitude and
duration of the inrush current varies depending on the equipment. Some inrush currents can be
as high as six times the rated capacity while some equipment produce negligible inrush currents.
To prevent severe inrush current damage to the inverter, the UPS is equipped with an electronic
overload protection feature. If the UPS load is between 105 and 120% of its capacity, it switches to
the bypass mode after 30 seconds to protect the inverter. If the overload condition is removed, the
UPS switches back to inverter mode. If the UPS load is more than 150% of its capacity, the inverter
shuts down immediately.

LOW

(battery

2. The UPS bypass loop is also equipped with overload protection. Its overload capacity is illustrated by
the graphs and table below.

42

0170009-J0 Rev B

A-5  Inverter Failure

If there is a short circuit in the output circuit when the power is supplied from the inverter, the UPS shuts
down the inverter to shut off power to the loads. The fail LED illuminates and the buzzer beeps con­tinuously. The UPS does not switch on automatically after the short circuit condition disappears. The UPS
must be re-started manually. Refer to Section 5.2.1, Start Up in Normal AC Mode.

A-6  Inverter/Internal Over temperature

The UPS switches to the bypass mode if the UPS experiences an internal over-temperature when the
utility voltage is normal. The UPS switches back to the inverter mode when the over-temperature disap­pears. If an over temperature occurs when the utility voltage is outside the UPS design limits, the buzzer
beeps continuously and the Fault LED illuminates. The UPS shuts off the power to the loads.

A-7  Inverter Over

An Inverter Over condition means that the current and inverter output voltages are outside the design
limits.

If the UPS inverter delivers an over-current and out-of-tolerance voltage to its outlets, the UPS is out of
order. The UPS switches to the bypass mode if the utility voltage is normal. The Utility LED, Bypass
LED, and Fault LED illuminate.

If these two fault conditions occur when the utility voltage is outside the UPS design limits, the UPS shuts
off the power to the loads and the Fault LED illuminates.
