1Introduction
The UPS EVO DSP PLUS RACK TOWER (UPS means Uninterruptible Power Supply) is the result of constant
technological research aimed at obtaining the best performance at the lowest cost.
EVO DSP PLUS RACK TOWER 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 RACK TOWER is a Double-Conversion ON-LINE UPS.
Under normal AC line condition EVO DSP PLUS RACK TOWER 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 RACK TOWER 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 RACK TOWER protects the devices from accidental overload or Inverter fault by an Automatic Bypass
that directly connects the AC Input line with its outlets.
EVO DSP PLUS RACK TOWER models are factory-equipped with RS-232 and USB interfaces, which may be used for
notify to a computer a power failure or a Low Battery condition: this allows automatic data backup during an
extended blackout with the most common operating systems (Windows, Linux, Unix, etc). Thanks to Interfaces,
UPS DSP MM can communicate the several made measurements (Input/Output Voltage, batteries, absorption,
Frequency, etc.), and can also be programmed in order to start-up or shutdown automatically at fixed times.
Read this manual carefully before using the EVO DSP PLUS RACK TOWER; it includes
important safety warnings and useful advices for correct use and installation.
EVO DSP PLUS RACK TOWER 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:
•EVO DSP PLUS 1.200 Rack Tower (1200VA)
•EVO DSP PLUS 2.400 Rack Tower (2400VA)
•EVO DSP PLUS 3.600 Rack Tower (3600VA)
In this manual EVO DSP PLUS RACK TOWER will simply be referred to as UPS.
EVO DSP PLUS RACK TOWER models are made from a single unit that contains the electronics parts and the
batteries.
However EVO DSP PLUS 3.600 MM RACK TOWER is predisposed to the connection with external BATTERY BOX units
in order to increase the autonomy (not possible on the other models).

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.

ENGLISH
User’s manual 4UPS EVO DSP PLUS Rack Tower
•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 Rack Tower 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.
Please refer to figure 2, which describe the UPS front panel.
The Normal mode is identified by:
•The graphic LCD panel shows the functioning during
Normal mode.
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 graphic LCD panel shows the functioning during
Battery mode.
•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.
When the UPS is working in Normal mode it is possible to switch the UPS by pressing SELECT + ON/MUTE button
for at least 5 seconds, as explained into chapter 5.
The Bypass mode is identified by:
•The graphic LCD panel shows the functioning during
Bypass mode.
•An acoustic signal every 10 seconds.
During Bypass mode, loads are fed directly from AC Input line. Therefore no protection
against AC Input line disturbances or interruptions is present.

ENGLISH
User’s manual 6UPS EVO DSP PLUS Rack Tower
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 and the graphic display is ON.
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 graphic LCD panel shows the functioning during
Stand-by mode.
4.5 ECO Mode
It is possible to select the ECO mode to save energy and to increase the efficiency of the UPS.
The ECO mode uses the Bypass to feed the loads. The UPS will operate as in Bypass mode whenever the
Frequency/waveform/RMS value of AC Input line mains Voltage is within their tolerance limits. If the AC Input line
Voltage goes beyond these limits, the UPS switches into normal operation.
Please contact Technical Service for the instruction to enable the ECO mode; by default the ECO mode is disable.
ECO mode does not provide perfect stability in Frequency/waveform/RMS value of the
Output Voltage like in Normal mode. Thus, the use of this mode should be carefully
executed according to the level of protection required by the application.
The ECO mode is identified by:
•The graphic LCD panel shows the functioning during ECO
mode (the “ECO” icon is ON).

ENGLISH
UPS EVO DSP PLUS Rack Tower 7User’s manual
4.6 CONVERTER FREQUENCY Mode
It is possible to select the Converter Frequency mode to work with the Output Frequency different from the Input
Frequency. For example it is possible to work with 60 Hz Input Frequency and 50 Hz Output Frequency or 50Hz
Input Frequency and 60 Hz Output Frequency.
Please contact Technical Service for the instruction to enable the Converter Frequency mode; by default
Converter Frequency mode is disable, and the Output Frequency will synchronize automatically with the Input
Frequency; by default the Converter Frequency mode is disable.
The Converter Frequency mode is identified by:
•The graphic LCD panel shows the functioning during
Converter Frequency mode.
•The “CVCF” characters are ON.

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 graphic display and goes in Stand-by mode: the UPS
recharges only the batteries and doesn’t supply Output power. Check the graphic display shows the
functioning of the battery charger during Stand-by mode.
4. Press ON/MUTE button for at least 3 seconds: the UPS emits a brief acoustic signal and performs a
functioning SELF-TEST. After some seconds the UPS starts to work in Normal Mode and the graphic LCD
panel will show the functioning during Normal mode.
5. Simulate a black-out by removing the AC Input line. The UPS starts working in Battery mode: the graphic LCD
panel will show the functioning 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 on the graphic LCD panel 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.

ENGLISH
User’s manual 16 UPS EVO DSP PLUS Rack Tower
8Functioning
8.1 Turning ON and OFF
Let’s see carefully the consequences of the pressure of ON/MUTE and OFF/ENTER buttons.
The UPS is in Stand-by mode (the Inverter is OFF); if the ON/MUTE 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 OFF/ENTER 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 OFF/ENTER button
Disconnect the AC Input Voltage for the UPS.
The graphic LCD 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/MUTE and
OFF/ENTER 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.
If the ON/MUTE 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/ENTER 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. icon on the graphic LCD 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
