1. Important Safety Instructions
1.1 Important Information
SAVE THIS MANUAL – 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.
• Make sure that the AC utility outlet is correctly grounded.
• Make sure that the input voltage to the UPS matches its name plate rating.
• Install the UPS indoors only as it is not designed for outdoor use.
• 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.
• Make sure the UPS is installed in an appropriate environment—0 to 40ºC (32 to 104ºF), and 30
to 90% relative humidity (non-condensing). Ensure the maximum ambient temperature does not
exceed 40ºC.
• Do not install the UPS in direct sunlight. Failure of the batteries under these conditions may void the
warranty.
• 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.
• A battery can present a risk of electrical shock and high short circuit current. Observe the following
precautions when working on batteries:
a. Remove watches, rings, or other metal objects.
b. Use tools with insulated 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 disconnecting battery terminals.
f. Determine if the battery is inadvertently grounded. If inadvertently 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 equipment and remote battery supplies not having a grounded supply circuit).
• 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:
a. Medical applications directly related to human life
b. Elevators, metro (subway) system or any other equipment related to human safety
c. Public security system or critical computer systems
• Make sure the UPS is completely switched off when moving the UPS from one place to another. It
may cause electrical shocks if the output is not completely switched off.

0170000-J0 Rev B
• 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 Instruction
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 pro-
cedure every 2 months if the ambient storage temperature is above 30ºC (86ºF).
1.3 Introduction
The Sentra Series UPS features a tower/rack convertible design, a single boost and single buck Auto-
matic Voltage Regulation (AVR), pure sine wave output, a user friendly LCD display, a built-in customer
option slot, hot swappable batteries, and a USB/RS232 communication interface. It provides a flexible
back-up system for critical file servers, minicomputers, network switches and hubs, and many other ap-
plications.
• The sine wave output is compatible with the requirements of many types of loads.
• A user friendly LCD panel displays the system status including the load level, battery level,
AVR-boost/buck, and fault status.
• 90% efficiency in the normal mode meets high energy saving standard and reduces noise and heat.
• Easy to swap internal batteries.
• A cold start function enables the UPS to be switched on without being connected to the utility power.
• Optional communication software allows the UPS to shutdown in a controlled manner when the
utility power fails. It also allows the user to remotely test the major operating functions of the UPS,
communicate via an SNMP/web/network optional card, access the UPS functions via the web, and
alert the user via SMS messages.
• The user friendly plug and play design allows the unit to be easily installed by the end user. All units
up to 3 kVA are supplied with input cables and output sockets.
• The USB / RS232 interface provides convenient plug and play with other IT products powered by the
UPS.

The UPS contains a microprocessor, which
must be installed in a well-ventilated and
humidity controlled environment. Select an
environment that minimizes the possibility of
damage to the UPS and extends the life of the
UPS. Follow the instructions below:
1. Ensure there is at least 20 cm (8 inches)
of clearance between the rear panel of the
UPS and the wall or other obstructions.
2. Do not block the air-flow to the ventilation
openings of the unit.
3. Ensure that the environmental conditions of
the installation site are within the specified
temperature and humidity limits. Avoid
excessive heat and moisture.
4. Do not place the UPS in a dusty or
corrosive environment or near any
flammable objects.
5. This UPS is not designed for outdoor use.

3. Installation
3.1 Connect Utility and Load
First, connect the UPS with the utility power, then plug the loads into the outlets on the rear of the UPS. To
use the UPS as a master on/off switch, make sure that all of the loads are switched on.
The UPS outlets provide battery backup and surge protection for the equipment when the utility voltage is
out of range.
For models 2200, 1500, 1000 and 750: To reduce the risk of re, connect only to a circuit
provided with 20 amperes maximum branch circuit overcurrent protection in accor-
dance with the National Electric Code, ANSI/NFPA 70".
CAUTION!
Do not connect a laser printer to the UPS outlets! The printer may overload the UPS and
shut it down.
CAUTION!
