UPS EVO DSP PLUS 1.2-2.4-3.6 MM
1 Introduction
The UPS EVO DSP PLUS MM (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 MM 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 MM is a Double-Conversion ON-LINE UPS.
Under normal AC line condition EVO DSP PLUS MM 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.), this protecting the devices connected to its outlets. During a power failure, EVO DSP
PLUS MM 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 MM 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 MM models are factory-equipped with 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 EVO DSP PLUS 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 MM; it includes important
safety warnings and useful advices for correct use and installation.
EVO DSP PLUS MM 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 MM 1.2 (1.2 KVA)
• EVO DSP PLUS MM 2.4 (2.4 KVA)
• EVO DSP PLUS MM 3.6 (3.6 KVA)
In this manual EVO DSP PLUS MM will simply be referred to as UPS.
EVO DSP PLUS MM models are made from a single unit that contains the electronics parts and the batteries.

3 Receipt 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.

UPS EVO DSP PLUS 1.2-2.4-3.6 MM
• 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.
4 Operating Modes
Figure 1 – Operating modes
BATTERY MODE
NORMAL MODE
BYPASS MODE
ENGLISH
UPS EVO DSP PLUS 1.2-2.4-3.6 MM 5 U
ser’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 path of energy flow
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 path of energy flow
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 continuously ON/MUTE and
SELECT buttons at the same time for at least 5 seconds, as explained into chapter 5.
ENGLISH
User’s manual 6
UPS EVO DSP PLUS 1.2-2.4-3.6 MM
The Bypass mode is identified by:
• The graphic LCD panel shows the path of energy flow
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.
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 path of energy flow
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 path of energy flow
during ECO mode (the “ECO” icon is ON).
