Safety Warnings
 Read this manual carefully and completely before installing and using the TECNOWARE EXA
Uninterruptible Power Supply, which, from here after, will also be referred to as UPS.
 This manual should be kept close to the UPS and read before the UPS is installed and used.
 The UPS must be used only by properly trained personnel. To ensure correct and safe
operations, it is necessary that operators and maintenance personnel observe the general
safety Standards as well as the specific instructions included in this manual.
 Risk of electric shock: do not remove the cover. The UPS contains internal parts, which are at a
high Voltage and are potentially dangerous, capable of causing injury or death by electric
shock.
 There are no internal parts in the UPS, which are user serviceable. Any repair or maintenance
work must be performed e clusively by qualified technical personnel authorized by
TECNOWARE. TECNOWARE declines any responsibility if this warning is disregarded.
 Warning to the technical personnel authorized for Service: since internal components are
connected to the batteries, they will remain powered, and therefore dangerous, even after the
UPS has been disconnected from AC power mains. Before any repair or maintenance work,
disconnect the batteries, by removing the positive cable (red colour) from the positive pole of
the battery.
 It is compulsory to ground the UPS according to Safety Standards. The AC mains power supply
socket used to power the UPS must have an earth connection.
 In the event of AC main power supply failure (when the UPS works in Battery mode), do not
unplug the power supply cable to the UPS to ensure earth continuity to the connected loads.
 Since the AC mains power supply cable acts as a separation device, the AC mains power socket
used to supply the UPS and/or the rear side of the UPS must be accessible to easily disconnect
the cable in case of dangerous conditions.
 Risk of electric shock at the Output lines when the UPS is ON.
 Risk of electric shock at the Output lines while the unit is connected to the AC utility line.
 Do not obstruct ventilation slots or holes and do not rest any object on top of the UPS.
 Do not insert objects or pour liquids in the ventilation holes.
 Install the UPS indoors, in a protected, clean and moisture-free environment.
 Do not e pose to the direct sun light.
 Do not keep liquids, flammable gases or corrosive substances near the UPS.

1Introduction
EXA is a Line Interactive Pure Sinewave UPS (Uninterru tible Power Su ly) s ecifically designed to rotect your
com uter from any ty e of irregularities in the AC line (such as black-outs, under or over voltages, micro-
interru tions), which often cause damage to your Hardware and Software.
Under normal AC line condition, EXA erforms out ut voltage regulation and filters frequently occurring electrical
disturbances (such as transients, s ikes, interferences, etc.), thus rotecting all devices connected to the outlets,
and recharging the batteries in an ideal way. In case of anomaly to the AC line, the UPS continues feeding the
rotected equi ment.
EXA is equi ed with a RS-232 or USB interface which can be used to notify a ower failure or a low battery
condition directly to a com uter: this makes it ossible to automatically save your data during an extended black-
out with the most wides read o erating systems (Windows, Linux, etc.).
Read this manual carefully before using the EXA; it includes important safety warnings
and useful advices for correct use and installation.
This manual is a guide that enables you to correctly install and use your EXA. This
manual includes important SAFETY instructions for the operator, for the UPS correct
installation, and gives useful advice on the product and battery maintenance. For any
type of problem, please refer to this manual before calling the customer service.
EXA is constantly being develo ed and im roved: consequently, your unit may differ somewhat from the
descri tion contained in this manual.
This manual includes the following models:
•EXA 1.1 (1.1 KVA)
•EXA 1.5 (1.5 KVA)
•EXA 2.2 (2.2 KVA)
•EXA 2.6 (2.6 KVA)
•EXA 3.2 (3.2 KVA)
In this manual EXA will sim ly be referred to as UPS.

returns.
•Ada ts automatically to 50 or 60 Hz in ut frequency.
•LCD dis lay for the visualization of the In ut and Out ut Voltage, Battery Level ercentage, Load Level
ercentage, functioning modes, alarm and fault conditions.
•Acoustic signals of various kinds indicating functioning modes and alarm/fault condition.
•Communication with the com uter through RS-232 and USB interfaces.
•SNMP Ada ter (o tional).
•Protects and filters the tele hone line.
•Fast swa able battery.
•High efficiency
•Maximum reliability
•Smart design and easy to use
3Receipt and site selection
Carefully remove the UPS from its ackaging, and carry out a meticulous ins ection. We recommend kee ing the
original ackaging in a secure lace, in case you need to send the UPS for maintenance ur oses. In case of
trans ort damage, notify the carrier and dealer immediately.
We recommend aying attention to the below oints in order to choose a correct lacement for your UPS:
•The UPS is designed to o erate in a rotected environment (e.g. offices). We therefore recommend
installing it in a lace with very little or no humidity, dust or smoke.
•In all circumstances, see the “Technical Characteristics” cha ter for environmental s ecifications and
check that the selected area meets these s ecifications.
•During normal o eration the UPS discharges a minimal amount of heat. So it is necessary to leave at least
20 cm of unobstructed s ace all around the UPS in order to kee it ro erly ventilated.
•Do not obstruct ventilation holes.
•Do not insert objects or our liquids in the ventilation holes.
•Do not rest any object on to of the UPS.
•Do not kee liquids, flammable gases or corrosive substances near the unit.
•Install the UPS on a ro erly tiled floor. Avoid the installation on a floor that is not tiled flat.

User’s manual 8 UPS EXA 1.1-1.5-2.2-2.6-3.2
5Electrical Installation and First Start Up
We advise you to follow the ste s below ex lained for greater safety:
1. Switch off all the devices (Personal Com uter or other electronic devices) that need to be su lied by the
UPS.
2. Connect the UPS In ut socket to the AC line outlet Through the Personal Com uter su lying cable. It is
mandatory to ground the AC line outlet according to the Safety Standards. Carefully check the grounding,
make sure that the utility ower is available, and that its range falls within the UPS s ecifications (refer to
the “S ecifications” cha ter).
3. Switch ON the ON/OFF button on the rear anel and then ress the ON/OFF button on the front anel for 3
seconds: the UPS emits a brief acoustic signal, turns the LCD dis lay on, and erforms a functioning SELF-
TEST. Leave the UPS in Normal mode for at least 4 hours in order to com letely recharge the batteries.
4. Switch the UPS off (by ressing again the ON/OFF button for 3 seconds).
5. Connect the devices to be su lied to the UPS out uts, by using only the included cables. Be sure all the
devices have the main switch in ON osition.
6. Turn on the UPS again. Check that it starts working correctly and it doesn’t signal any sort of anomaly.
Moreover be sure that all the devices connected to the UPS out uts are working correctly. By LCD dis lay
check if the Out ut load ercentage is less than 100%; otherwise it is necessary to remove art of the Out ut
load.
7. Simulate a black-out by removing the AC In ut line. The UPS starts working in Battery mode. Moreover the
UPS emits a brief acoustic signal every 10 seconds.
8. Be sure that all the devices connected to the UPS out uts are working correctly and the UPS doesn’t signal
any sort of anomaly.
9. Restore the AC In ut line: after few seconds the UPS turns back in Normal mode.
Before using EXA normally, leave it in Normal mode in order to charge the batteries com letely as s ecified at
oint 3. The batteries reach the 90% of their ca acity after about 4 hours of recharge.
It is compulsory to ground/earth the UPS according to the Safety Standards.
Risk of electric shock at the Output lines if the UPS is ON, even when the UPS is not
connected to AC utility line.
Risk of electric shock at the Output lines while the unit is connected to the AC utility
line.
Risk of electric shock: do not remove the cover. The UPS contains internal parts, which
are at a high Voltage and are potentially dangerous, capable of causing injury or death
by electric shock.
There are no internal parts in the UPS that are user serviceable. Any repair or
maintenance work must be performed e clusively by qualified technical personnel
authorized by TECNOWARE. TECNOWARE declines any responsibility if this warning is
disregarded.
Disregard for these warnings may lead to a risk of electric shock to operators.
