1Introduction
ERA PLUS is a Line Interactive UPS (Uninterruptible Power Supply) specifically designed to protect your computer
from any type of irregularities in the AC line (such as black-outs, under or over voltages, micro-interruptions),
which often cause damage to your Hardware and Software.
Under normal AC line condition, ERA PLUS performs output voltage regulation and filters frequently occurring
electrical disturbances (such as transients, spikes, interferences, etc.), thus protecting 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 protected equipment.
ERA PLUS is equipped with an USB interface which can be used to notify a power failure or a low battery condition
directly to a computer: this makes it possible to automatically save your data during an extended black-out with
the most widespread operating systems (Windows, Mac OS X, Linux, etc.).
Read this manual care ully be ore using the ERA PLUS; it includes important sa ety
warnings and use ul advices or correct use and installation.
This manual is a guide that enables you to correctly install and use your ERA PLUS. This
manual includes important SAFETY instructions or the operator, or the UPS correct
installation, and gives use ul advice on the product and battery maintenance. For any
type o problem, please re er to this manual be ore calling the customer service.

3Receipt and site selection
Carefully remove the UPS from its packaging, and carry out a meticulous inspection. We recommend keeping the
original packaging in a secure place, in case you need to send the UPS for maintenance purposes. In case of
transport damage, notify the carrier and dealer immediately.
We recommend paying attention to the below points in order to choose a correct placement for your UPS:
•The UPS is designed to operate in a protected environment (e.g. offices). We therefore recommend
installing it in a place with very little or no humidity, dust or smoke.
•In all circumstances, see the “Technical Characteristics” chapter for environmental specifications and
check that the selected area meets these specifications.
•During normal operation the UPS discharges a minimal amount of heat. So it is necessary to leave at least
20 cm of unobstructed space all around the UPS in order to keep it properly ventilated.
•Do not obstruct ventilation holes.
•Do not insert objects or pour liquids in the ventilation holes.
•Do not rest any object on top of the UPS.
•Do not keep liquids, flammable gases or corrosive substances near the unit.

UPS ERA PLUS 900-1.100 7 User’s manual
We advise you to follow the steps below explained for greater safety:
1. Switch off all the devices (Personal Computer or other electronic devices) that need to be supplied by the
UPS.
2. Connect the UPS Input socket to the AC line outlet. It is mandatory to ground the AC line outlet according
to the Sa ety Standards. Carefully check the grounding, make sure that the utility power is available, and
that its range falls within the UPS specifications (refer to the “Specifications” chapter).
3. Press the ON/OFF button on the front panel: the UPS emits a brief acoustic signal, turns the led display on,
and performs a unctioning SELF-TEST. After some seconds the UPS starts to work in Normal mode. Leave
the UPS in ormal mode for at least 4 hours in order to completely recharge the batteries.
4. Switch the UPS off (by pressing again the O /OFF button).
5. Connect the devices to be supplied to the UPS outputs. Be sure all the devices have the main switch in O
position.
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 outputs are working correctly.
7. Simulate a black-out by removing the AC Input line. The UPS starts working in Battery mode: the UPS emits a
brief acoustic signal every 10 seconds.
8. Be sure that all the devices connected to the UPS outputs are working correctly and the UPS doesn’t signal
any sort of anomaly.
9. Restore the AC Input line: after few seconds the UPS turns back in ormal mode.
Before using ERA PLUS normally, leave it in ormal mode in order to charge the batteries completely as specified
at point 3. The batteries reach the 90% of their capacity after about 4 hours of recharge.
It is compulsory to ground/earth the UPS according to the Sa ety Standards.
Risk o electric shock at the Output lines i the UPS is ON, even when the UPS is not
connected to AC utility line.
Risk o electric shock at the Output lines while the unit is connected to the AC utility
line.
Risk o electric shock: do not remove the cover. The UPS contains internal parts, which
are at a high Voltage and are potentially dangerous, capable o 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 per ormed exclusively by quali ied technical personnel
authorized by TECNOWARE. TECNOWARE declines any responsibility i this warning is

6Functioning
6.1 Normal Mode
The UPS typically works in Normal mode: Input mains power is available and its amplitude is within specifications.
In ormal mode the LINE/BATTERY led is always on.
During ormal mode, the UPS recharges the batteries and keeps them in an optimal charging voltage.
6.2 Battery Mode
The UPS automatically runs in Battery mode if the AC Input Line voltage amplitude gets out of security limits (in
case of a black-out or over-voltage/low-voltage): in this case, the UPS supplies the required output power by its
internal battery and by the Inverter block.
The UPS automatically returns in ormal mode a few seconds after the AC Input Line is recovered.
In Battery mode the UPS emits an acoustic alarm signal every 10 seconds and simultaneously the LINE/BATTERY
led flashes.
6.3 Low Battery and Automatic Restart
In Battery mode, ERA PLUS indicates the Low Battery condition whenever the battery reaches a charge level
allowing connected devices to operate for approximately one more minute.
During Low Battery condition the UPS emits an acoustic alarm signal every second and simultaneously the
LINE/BATTERY led flashes.
If AC Input does not come back on within few minutes, the UPS shuts-down automatically thus preventing the
batteries from discharging excessively; the UPS stops supplying Output power, deactivates control panel indication
and goes to a waiting state. Once AC Input comes back on, the UPS restarts automatically and after some seconds
it goes back to work in ormal mode.
After a complete discharge, the UPS needs 4 hours to recharge completely the batteries. The UPS recharges
batteries automatically if it works in ormal mode or if it is off and connected to the AC Input Line.

UPS ERA PLUS 900-1.100 9 User’s manual
6.4 Load Control
When the Output load is higher than nominal value the UPS warns of Overload condition by emitting a continuous
acoustic alarm.
The UPS warns of an Overload less than 110% by acoustic alarm.
An Overload between 110% and 130% is accepted for about 30 seconds and after UPS switches automatically off.
The UPS switches immediately off if the Overload is higher than than 130%.
Once the requested power is back within range, the UPS switches automatically to the ormal mode.
Make sure that the UPS never indicates Overload condition.
Do not connect a load greater than rated value to the UPS (see POWER speci ications in
the chapter “Technical Characteristics”), as this may damage the unit. In this case the
warranty is void.
6.5 Fault Condition
The UPS indicates the Fault condition by emitting a continuous acoustic alarm.
During Fault condition, the UPS doesn’t supply Output power and so all the supplied devices are switched off.
7Communication Inter ace
The UPS is factory-equipped with USB Communication Inter ace (only ERA Plus 1.100). On the UPS rear side
there is the connector of the USB Interface.
The USB signals are all isolated through photo-couplers rom the dangerous voltages that are present inside
the UPS.
