User’s manual 2UPS EVO DSP PLUS
1Introduction
The EVO DSP PLUS (UPS means Uninterruptible Power Supply) is the result of constant technological research
aimed at obtaining the best performance at the lowest cost.
UPS EVO DSP PLUS is an advanced ON-LINE UPS built specifically to protect your computer from any irregularities
in the AC line (for example blackouts, brownouts, over voltages, micro-interruptions), which often cause damage
to hardware and software.
All that is possible because EVO DSP PLUS is a Double-Conversion ON-LINE UPS.
Under normal AC line condition EVO DSP PLUS provides an automatic Output Voltage regulation from the Rectifier
and Inverter blocks and filters out frequently occurring electrical disturbances (high Voltage transients, spikes,
interferences, etc.), thus protecting the devices connected to its outlets. During a power failure, EVO DSP PLUS
continues supplying adequate AC power (with a true sine wave) to all connected devices through its internal
batteries and by its DC/AC converter (Inverter).
EVO DSP PLUS protects the devices from accidental overload or Inverter fault by an Automatic Bypass that directly
connects the AC Input line with its outlets.
Read this manual carefully before using the EVO DSP PLUS; it includes important safety
warnings and useful advices for correct use and installation.
EVO DSP PLUS is constantly being developed and improved: consequently, your unit may differ somewhat from the
description contained in this manual.
This manual includes the following models:
•UPS EVO DSP PLUS 800 PF 0.9
In this manual EVO DSP PLUS will simply be referred to as UPS.
EVO DSP PLUS models are made from a single unit that contains the electronics parts and the batteries.

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.
•When the UPS is brought from a cold place to a warmer place, humidity in the air may cause condensation
in the UPS. In this case, allow UPS to stand for two hours in the warmer place before beginning with the
installation.
•In all circumstances, see the “Technical Characteristics”chapter for environmental specifications and
check that the selected area meets these criteria.
•During normal operation the UPS discharges a minimal amount of heat. So it is necessary to leave at least
10 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.
•Install the UPS on a properly tiled floor. Avoid the installation on a floor that is not tiled flat.

4Operating Modes
Figure 1 –Operating modes

ENGLISH
UPS EVO DSP PLUS 5User’s manual
4.1 NORMAL Mode
The UPS typically works in Normal mode: Input mains power is available and its amplitude is within specifications.
Please refer to figure 1.
After the filter has eliminated any high Frequency interference present on the mains, the AC Input line is rectified
and conditioned in the Rectifier block (AC/DC conversion); the continuous power now enters into the Inverter
block and is then reconverted into alternated power (DC/AC conversion), overcoming the Automatic Bypass and
feeding the load after an extra filtration. At the same time the UPS recharges the batteries through the Battery
Charger block.
The Normal mode is identified by:
•The Led panel LED1, LED4, LED 7 are on (see fig. 3)
4.2 BATTERY Mode
During operation in Normal mode, if the UPS finds the Mains OFF condition (due to a Blackout or
Overvoltage/Brownout), it then switches into Battery mode. In this case, the batteries supply the required Output
power thanks to the DC/AC conversion carried out by the Inverter. The UPS switches back to Normal mode a few
seconds after AC Input power is restored or Voltage comes back to internal specifications.
Please refer to figure 1.
The Battery mode is identified by:
•The Led panel LED2, LED4, LED 7 are on (see fig. 3)
•An acoustic signal every 4 seconds.
4.3 BYPASS Mode
In Bypass mode, the AC Input line is directly connected with the UPS outlets by an Automatic Bypass.
As indicated in figure 1, in Bypass mode the UPS recharges the batteries.
During Normal mode, the UPS switches automatically to Bypass mode as a consequence of accidental overload
or Inverter fault thus protecting the supplied devices.
The Bypass mode is identified by:
•The Led panel LED3, LED4, LED 7 are on (see fig. 3)
During Bypass mode, loads are fed directly from AC Input line. Therefore no protection
against AC Input line disturbances or interruptions is present.
4.4 STAND-BY Mode
If the UPS is in Stand-by mode, it is “inactive”. In Stand-by mode the Inverter is off and there is not Output power
but the UPS is not completely off: indeed the UPS recharges the batteries regularly.
If the OFF button is pressed when the UPS is in Normal mode, the UPS switches in Stand-by mode.
If the UPS is in Stand-by mode and the AC Input line is removed from UPS, then the UPS switches completely off.
The Stand-by mode is identified by:
•The Led panel LED4, LED 7 are on (see fig. 3).

6Electrical Installation
The electrical installation has to be done by qualified personnel. Follow all the Safety
Standards (CEI Standards in Italy or IEEE elsewhere) for the Input/Output connections
and for the right selection of Input/Output cables.
For safety we recommend using external circuit breakers between Input mains and UPS
AC Input line and between UPS Output lines and the loads. The circuit breakers should
be qualified with leakage current protective function (leakage current < 30 mA).
For the Input/Output connections use ONLY the included power cables or cables with
the same power ratings.
The producer declines any responsibility if this warning is disregarded.
The EVO DSP PLUS models are made of a single unit design that contains the electronic parts and batteries.
Before starting the installation procedure, be sure that:
1. The AC Input Voltage for the UPS has been removed.
2. The UPS is completely OFF.
6.1 Installation
We advise you to follow the steps below explained:
1. Through the included power cable connect the UPS Input socket to the AC line outlet (see figure 4). It is
mandatory to ground the AC line outlet according to the Safety Standards. Carefully check the grounding
of AC line outlet.
2. Connect the devices to be supplied to the UPS outputs. Be sure all the devices have the main switch in OFF
position.
It is compulsory to ground the UPS according to the Safety Standards.
The case of the UPS is internally connected to the ground terminal (GND) of the IN/OUT
terminals, in order to guarantee safety to the user. To guarantee safety it is necessary
to be sure that the local electric plant is supplied with GROUND (in compliance with the
Safety Standards), and that a valid connection is guaranteed between the GROUND of
the UPS and the GROUND of the local electric plant.
Any interruption of the GROUND conductor is absolutely prohibited.
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 which are user serviceable. Any repair or
maintenance work must be performed exclusively by qualified technical personnel
authorized by the producer. The producer declines any responsibility if this warning is
disregarded.
Disregard for these warnings may lead to a risk of electric shock to operators.

ENGLISH
User’s manual 10 UPS EVO DSP PLUS
7First Start Up
Turning the UPS ON is very easy. Nevertheless, we recommend that, on First Start Up, the following procedure is
observed for greater safety.
1. Be sure all the devices connected to the UPS outputs have the main switch in OFF position.
2. Restore the AC Input line for the UPS; be sure that the AC utility power is available, and that its voltage and
frequency are within the specifications.
3. As a consequence of point 2, the UPS turns on the led panel and goes in Stand-by mode: the UPS recharges
only the batteries and doesn’t supply Output power. Check the led panel shows the path of energy flow
during Stand-by mode.
4. Press ON/OFF button: all led will flash few second, then the UPS will turn ON and it starts to work in Normal
Mode.
5. Simulate a black-out by removing the AC Input line. The UPS starts working in Battery mode: the led panel
will show the path of energy during Battery mode. Moreover, UPS emits a brief acoustic signal every 4
seconds. When Battery level is ending the acoustic signal will be emitted every 1 second.
6. Restore the AC Input line: after few seconds the UPS turns back in Normal mode.
7. The UPS has passed first start up check: now turn ON the devices (one by one) to be supplied by UPS,
checking the UPS doesn’t report Overload information and all the devices are working regularly. By graphic
display check if the Output load percentage is less than 100%; otherwise, it is necessary to remove part of the
loads at the Output lines.
Before using the UPS normally, leave it in Normal mode for in order to charge Battery completely (the UPS charges
Battery also in Bypass mode or in Stand-by Mode). The batteries reach the 90% of their capacity after about 4
hours of recharge.

UPS EVO DSP PLUS 11 User’s manual
8Functioning
8.1 Turning ON and OFF
Let’s see carefully the consequences of the pressure of ON/OFF buttons.
The UPS is in Stand-by mode (the Inverter is OFF); if the ON/OFF button is pressed, after few seconds the Inverter
starts and the UPS switches in Normal mode.
The UPS is in Normal mode (the Inverter is ON); if the ON/OFF button is pressed, the Inverter turns OFF and the
UPS switches in Stand-by mode.
To turn completely OFF the UPS please do the following steps:
Put the UPS in Stand-by mode by pressing the ON/OFF button
Disconnect the AC Input Voltage for the UPS.
The Led panel is OFF only when the UPS is completely OFF.
If UPS is used daily, it is recommended to leave the UPS connected to the AC Input line and use the ON/OFF
buttons on the front panel to activate/deactivate the Inverter.
If the UPS has to be turn OFF completely for several days, it is recommended to disconnect the AC Input line for
the UPS and then press the ON/OFF button.
If the ON/OFF button is pressed when AC Input line is not present, the UPS switches ON even, and works in Battery
mode after some seconds.
If the OFF button is pressed when AC Input line is not present, then the Inverter switches OFF and consequently
there will be no Output power.
8.2 Low Battery and Automatic Restart
The UPS reaches the Low Battery condition whenever, during working in Battery mode, the batteries reach a
charge level allowing the connected devices to operate for few minutes more.
The UPS warns operators of Low Battery by lighting of the LOW BATT. led on led panel and by emitting an
acoustic signal every second.
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 4 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, in Bypass mode or in Stand-By mode.

ENGLISH
User’s manual 12 UPS EVO DSP PLUS
8.3 Load Testing
The UPS indicates the Output Load level by led panel.
When the Output load is higher than nominal value the UPS warns of Overload condition by led panel and by
acoustic alarm as described in the “Warning Table” and in the “Troubleshooting” chapter.
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 to the
Bypass mode.
The UPS switches immediately to the Bypass mode 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 indicates Overload condition.
Do not connect a load greater than rated value to the UPS (see POWER specifications in
the chapter “Technical Characteristics”), as this may damage the unit. In this case the
warranty is void.
8.4 Static Bypass
During Normal mode, the UPS switches automatically to Bypass mode as a consequence of accidental overload
or Inverter fault thus protecting the supplied devices.
Maintenance and service may only be performed by authorized technical personnel.
During Static Bypass, loads are fed directly from Bypass mains. Therefore no protection
against mains disturbances or interruptions is present.

11.1 UPS Cleaning
Before starting any cleaning operation, be sure that:
1. The AC Input Voltage for the UPS has been removed.
2. The UPS is completely OFF (the LED panel is OFF).
Use only a cloth dampened with water to clean the unit.
If UPS works in an environmental unusually dusty or dirty, remove the dirty from the ventilation holes.
Before restarting the UPS be sure it is completely dry. If any liquid gets inside the UPS, do not start the unit and
contact Technical Service immediately.
11.2 Battery
If the UPS is NOT going to be used for a long period of time, ensure that the batteries are left fully charged.
If the UPS has not been used for more than three months, go through the procedure described in the chapter 7
“First Start Up”before using it again.
Please keep in mind that the batteries must be recharged at least once a month. Take in mind that batteries are
recharged automatically (if the UPS is ON and working in Normal or in Bypass mode) for after approximately 4
hours with AC Input line present.
Battery life strongly depends on the ambient temperature. There are also other factors like the number of charge-
discharge cycles, the discharge depth, humidity and altitude.
The recommended environmental specifications for a correct use of batteries are listed in the “Technical
Specifications” section.
Performing Battery Test can provide you with information about Battery condition (see “Battery Test” section for
more information on Battery Test).
Danger of explosion and fire if batteries of the wrong type or number are used.
Do not dispose of batteries in a fire. The batteries may explode. Do not open or mutilate
batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
11.3 Operator Safety
Whenever the UPS is not responding anymore to original characteristics, the UPS must be made non-operative and
every usage not authorised must be avoided. After it will be necessary to refer to qualified technical personnel.
Original safety characteristics might not be if, for example, the UPS has visible damage or irregular operation.
