1Intro uction
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.).
Rea this manual carefully before using the ERA PLUS; it inclu es important safety
warnings an useful a vices for correct use an installation.
This manual is a gui e that enables you to correctly install an use your ERA PLUS. This
manual inclu es important SAFETY instructions for the operator, for the UPS correct
installation, an gives useful a vice on the pro uct an battery maintenance. For any
type of problem, please refer to this manual before calling the customer service.

3Receipt an 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.

6Functioning
6.1 Normal Mo e
The UPS typically works in Normal mo e: Input mains power is available and its amplitude is within specifications.
In Normal mode the LINE/BATTERY led is always on.
During Normal mode, the UPS recharges the batteries and keeps them in an optimal charging voltage.
6.2 Battery Mo e
The UPS automatically runs in Battery mo e 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 Normal 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 an 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- own 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 Normal mode.
After a complete discharge, the UPS needs 4 hours to recharge completely the batteries. The UPS recharges
batteries automatically if it works in Normal mode or if it is off and connected to the AC Input Line.

6.4 Loa Control
When the Output load is higher than nominal value the UPS warns of Overloa con ition 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 Normal mode.
Make sure that the UPS never in icates Overloa con ition.
Do not connect a loa greater than rate value to the UPS (see POWER specifications in
the chapter “Technical Characteristics”), as this may amage the unit. In this case the
warranty is voi .
6.5 Fault Con ition
The UPS indicates the Fault con ition 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 Interface
The UPS is factory-equipped with USB Communication Interface (only ERA Plus 1.100 an ERA Plus 1.500). On
the UPS rear side there is the connector of the USB Interface.
The USB signals are all isolate through photo-couplers from the angerous voltages that are present insi e
the UPS.
