User’s manual 2 UPS EVO DSP PLUS TT
1Introduction
UPS EVO DSP PLUS TT (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 TT 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 UPS EVO DSP PLUS TT is a Double-Conversion ON-LINE UPS.
Under normal AC line condition UPS EVO DSP PLUS TT 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, UPS EVO
DSP PLUS TT 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).
UPS EVO DSP PLUS TT protects the devices from accidental overload or Inverter fault by an Automatic Bypass that
directly connects the AC Input line with its outlets.
UPS EVO DSP PLUS TT 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 EVO DSP
PLUS TT 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.
Re d this m nu l c refully before using the UPS EVO DSP PLUS TT; it includes import nt
s fety w rnings nd useful dvices for correct use nd inst ll tion.
UPS EVO DSP PLUS TT 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 TT 10 KVA
•UPS EVO DSP PLUS TT 15 KVA
•UPS EVO DSP PLUS TT 20 KVA
In this manual UPS EVO DSP PLUS TT will simply be referred to as UPS.
EVO DSP PLUS TT models are made from a single unit that contains the electronics parts and the batteries.
However EVO DSP PLUS TT models are predisposed to the connection with external BATTERY BOX units in order to
increase the autonomy.

3Receipt nd 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 4 UPS EVO DSP PLUS TT
•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
25 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.

4.1 UPS Power On
When UPS is powered on, it will enter into this mode for a few seconds as initializing the CPU and system.
All the icons on the graphic LCD panel are ON.
All the leds are ON.

ENGLISH
User’s manual 6 UPS EVO DSP PLUS TT
4.2 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:
1. Line led is ON.
2. The graphic LCD panel shows the path of energy
flow during Normal mode.
4.3 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.

ENGLISH
UPS EVO DSP PLUS TT 7 User’s manual
The Battery mode is identified by:
1. B ttery led is ON.
2. The graphic LCD panel shows the path of energy
flow during Battery mode.
3. An acoustic signal every 4 seconds.
4.4 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.
If you connect the AC Input line to the UPS and the Input line breaker on the rear is “ON”, the UPS will go to
Bypass mode.
The Bypass mode is an idle mode for the UPS: then by pressing ON button, the UPS turns ON completely,
activating the Inverter block.
When the UPS works in Bypass mode it can be considered as “not active”, since the Inverter block is not active.
The UPS is considered “active” when the Inverter block is ON (in Normal mode and in Battery mode).
Furthermore the UPS switches utom tic lly to Byp ss mode s consequence of ccident l overlo d or
Inverter f ult thus protecting the supplied devices.

ENGLISH
User’s manual 8 UPS EVO DSP PLUS TT
The Bypass mode is identified by:
1. Byp ss led is ON.
2. The graphic LCD panel shows the path of energy
flow during Bypass mode.
3. An acoustic signal every 2 minutes.
During Byp ss mode, lo ds re fed directly from AC Input line. Therefore no protection
g inst AC Input line disturb nces or interruptions is present.
4.5 NO-OUTPUT Mode
When Bypass voltage/frequency is out of acceptable range or Bypass is disabled, UPS will enter into No-Output
mode if powering on or turning off the UPS. It means the UPS has no output.

ENGLISH

The No-Output mode is identified by:
1. All he leds are OFF.
2. The graphic LCD panel shows the path of energy
flow during No-Output mode.
3. An acoustic signal every 2 minutes.
4.6 BATTERY TEST mode
When UPS is in AC mode or CVCF mode, press “Test” key for more than 0.5s. Then, the UPS will beep once and
start the Battery Test mode. The line between I/P and inverter icons will blink to remind users. This operation is
used to check the battery status.
The Battery Test mode is identified by:
1. B ttery, Line and Byp ss leds are ON.
2. The graphic LCD panel shows the path of energy
flow during Battery Test mode.

ENGLISH
User’s manual 10 UPS EVO DSP PLUS TT
4.7 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 ECO mode is disable.
ECO mode does not provide perfect st bility in Frequency/w veform/RMS v lue of the
Output Volt ge like in Norm l mode. Thus, the use of this mode should be c refully
executed ccording to the level of protection required by the pplic tion.
The ECO mode is identified by:
1. Byp ss and Line leds are ON.
2. The graphic LCD panel shows the path of energy
flow during ECO mode (the “ECO” icon is ON).
