User’s manual 2 UPS EVO DSP PLUS MM
1Introduction
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.), thus 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 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 thi manual carefully before u ing the EVO DSP PLUS MM; it include important
afety warning and u eful advice for correct u e and in tallation.
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 1.0 (1 KVA - pf. 0,9)
•EVO DSP PLUS MM 2.0 (2 KVA - pf. 0,9)
•EVO DSP PLUS MM 3.0 (3 KVA – pf. 0,9)
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.

3Receipt and ite election
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 4 UPS EVO DSP PLUS 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.

ENGLISH
UPS EVO DSP PLUS MM 5 User’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 witche automatically to Bypa mode a a con equence of accidental overload
or Inverter fault thu protecting the upplied device .
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 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 Bypa mode, load are fed directly from AC Input line. Therefore ome
protection again t AC Input line di turbance or interruption i pre ent.
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.

7Fir t 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 path of
energy flow 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 path of energy 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 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 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 14 UPS EVO DSP PLUS MM
8Functioning
8.1 Turning ON and OFF
Let’s see carefully the consequences of the pressure of ON/MUTE and OFF 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 button is pressed, the Inverter turns OFF and the UPS
switches in Stand-by mode.
To turn completely OFF the UPS plea e do the following tep :
Put the UPS in Stand-by mode by pre ing the OFF button
Di connect the AC Input Voltage for the UPS.
The graphic LCD panel i OFF only when the UPS i 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 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 OFF button.
If the ON 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 Re tart
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 hut -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 re tart 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
UPS EVO DSP PLUS MM 15 User’s manual
8.3 Load Te ting
The UPS indicates the Output Load level by graphic LCD (on the right side as described in the chapter 5).
When the Output load is higher than nominal value the UPS warns of Overload condition by graphic LCD 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 130%.
Once the requested power is back within range, the UPS switches automatically to the Normal mode.
Make ure that the UPS never indicate Overload condition.
Do not connect a load greater than rated value to the UPS ( ee POWER pecification in
the chapter “Technical Characteri tic ”), a thi may damage the unit. In thi ca e the
warranty i void.
8.4 Static Bypa
During Normal mode functioning it is possible to switch the UPS in Bypass mode, by pressing at the same time
ON/MUTE and SELECT buttons at least 5 seconds, as explained into chapter 5.
The Bypass mode, named also Static Bypa , is useful while performing maintenance or service on the UPS.
The Static Bypass, used together with an external Manual Bypass device, enables the user to isolate the electronic
circuitry of the UPS from the mains and from the load, and to remove the UPS without interrupting the power by
connecting the load directly to the mains.
Maintenance and ervice may only be performed by authorized technical per onnel.
During Static Bypa , load are fed directly from Bypa main . Therefore ome
protection again t AC Input line di turbance or interruption i pre ent.

9Communication Interface
The UPS is factory-equipped with RS232 and USB Communication Interface . On the UPS rear side there are the
connections of the Interfaces.
Only one of the RS232/USB communications can be activated at one time. To activate RS232 communication it is
sufficient to connect the RS232 cable only (9 pins cable, pin to pin); to activate USB communication it is sufficient
to connect the USB cable only.
The RS-232 and USB ignal are all i olated through photo-coupler from the dangerou voltage that are
pre ent in ide the UPS.
Connecting to the Web site www.tecnoware.com, it is possible to download, free of charge, the update UPS
management Software, compatible with the most popular Operative Systems.
It is possible to use a SNMP (Single Network Management Protocol) Interface to connect the UPS to a LAN (Local
Area Network). The SNMP interface is optional.
We advise you to follow the steps below explained to install the interface correctly:
1. Remove the metallic panel (#3, figure 4) that covers the slot for SNMP interface.
2. Put the SNMP Interface into the slot and fix it with screws.
3. Connect the LAN cable to SNMP interface and follow the included instruction to make the interface working
well.
