UPS EVO DSP PLUS 1.2-2.4-3.6 MM 5 Use ’s manual
4.1 NORMAL Mode
The UPS typically wo ks in No mal mode: Input mains powe is available and its amplitude is within specifications.
Please efe to figu e 1.
Afte the filte has eliminated any high F equency inte fe ence p esent on the mains, the AC Input line is ectified
and conditioned in the Rectifie block (AC/DC conve sion); the continuous powe now ente s into the Inve te
block and is then econve ted into alte nated powe (DC/AC conve sion), ove coming the Automatic Bypass and
feeding the load afte an ext a filt ation. At the same time the UPS echa ges the batte ies th ough the Batte y
Cha ge block.
Please efe to figu e 2, which desc ibe the UPS f ont panel.
The No mal mode is identified by:
•The g aphic LCD panel shows the path of ene gy flow
du ing No mal mode.
4.2 BATTERY Mode
Du ing ope ation in No mal mode, if the UPS finds the Mains OFF condition (due to a Blackout o
Ove voltage/B ownout), it then switches into Batte y mode. In this case, the batte ies supply the equi ed Output
powe thanks to the DC/AC conve sion ca ied out by the Inve te . The UPS switches back to No mal mode a few
seconds afte AC Input powe is esto ed o Voltage comes back to inte nal specifications.
Please efe to figu e 1.
The Batte y mode is identified by:
•The g aphic LCD panel shows the path of ene gy flow
du ing Batte y mode.
•An acoustic signal eve y 4 seconds.
4.3 BYPASS Mode
In Bypass mode, the AC Input line is di ectly connected with the UPS outlets by an Automatic Bypass.
As indicated in figu e 1, in Bypass mode the UPS echa ges the batte ies.
Du ing No mal mode, 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.
When the UPS is wo king in No mal mode it is possible to switch the UPS by p essing continuously ON/MUTE and
SELECT buttons at the same time fo at least 5 seconds, as explained into chapte 5.

ENGLISH
Use ’s manual 6 UPS EVO DSP PLUS 1.2-2.4-3.6 MM
The Bypass mode is identified by:
•The g aphic LCD panel shows the path of ene gy flow
du ing Bypass mode.
•An acoustic signal eve y 10 seconds.
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.
4.4 STAND-BY Mode
If the UPS is in Stand-by mode, it is “inactive”. In Stand-by mode the Inve te is off and the e is not Output powe
but the UPS is not completely off: indeed the UPS echa ges the batte ies egula ly and the g aphic display is ON.
If the OFF button is p essed when the UPS is in No mal mode, the UPS switches in Stand-by mode.
If the UPS is in Stand-by mode and the AC Input line is emoved f om UPS, then the UPS switches completely off.
The Stand-by mode is identified by:
•The g aphic LCD panel shows the path of ene gy flow
du ing Stand-by mode.
4.5 ECO Mode
It is possible to select the ECO mode to save ene gy and to inc ease the efficiency of the UPS.
The ECO mode uses the Bypass to feed the loads. The UPS will ope ate as in Bypass mode wheneve the
F equency/wavefo m/RMS value of AC Input line mains Voltage is within thei tole ance limits. If the AC Input line
Voltage goes beyond these limits, the UPS switches into no mal ope ation.
Please contact Technical Se vice fo the inst uction to enable the ECO mode; by default the 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:
•The g aphic LCD panel shows the path of ene gy flow
du ing ECO mode (the “ECO” icon is ON).

7First St rt Up
Tu ning the UPS ON is ve y easy. Neve theless we ecommend that, on Fi st Sta t Up, the following p ocedu e is
obse ved fo g eate safety.
1. Be su e all the devices connected to the UPS outputs have the main switch in OFF position.
2. Resto e the AC Input line fo the UPS; be su e that the AC utility powe is available, and that its voltage and
f equency a e within the specifications.
3. As a consequence of point 2, the UPS tu ns on the g aphic display and goes in St nd-by mode: the UPS
echa ges only the batte ies and doesn’t supply Output powe . Check the g aphic display shows the path of
ene gy flow du ing Stand-by mode.
4. P ess ON/MUTE button fo at least 3 seconds: the UPS emits a b ief acoustic signal and pe fo ms a
functioning SELF-TEST. Afte some seconds the UPS sta ts to wo k in Norm l Mode and the g aphic LCD
panel will show the path of ene gy du ing No mal mode.
5. Simulate a black-out by emoving the AC Input line. The UPS sta ts wo king in B ttery mode: the g aphic LCD
panel will show the path of ene gy du ing Batte y mode. Mo eove UPS emits a b ief acoustic signal eve y 4
seconds. When Batte y level is ending the acoustic signal will be emitted eve y 1 second.
6. Resto e the AC Input line: afte few seconds the UPS tu ns back in Norm l mode.
7. The UPS has passed fi st sta t up check: now tu n ON the devices (one by one) to be supplied by UPS,
checking the UPS doesn’t epo t Overlo d info mation on the g aphic LCD panel and all the devices a e
wo king egula ly. By g aphic display check if the Output load pe centage is less than 100%; othe wise it is
necessa y to emove pa t of the loads at the Output lines.
Befo e using the UPS no mally, leave it in No mal mode fo in o de to cha ge Batte y completely (the UPS cha ges
Batte y also in Bypass mode o in Stand-by Mode). The batte ies each the 90% of thei capacity afte about 4

8Functioning
8.1 Turning ON nd OFF
Let’s see ca efully the consequences of the p essu e of ON/MUTE and OFF buttons.
The UPS is in Stand-by mode (the Inve te is OFF); if the ON/MUTE button is p essed, afte few seconds the
Inve te sta ts and the UPS switches in No mal mode.
The UPS is in No mal mode (the Inve te is ON); if the OFF button is p essed, the Inve te tu ns OFF and the UPS
switches in Stand-by mode.
To turn completely OFF the UPS ple se do the following steps:
Put the UPS in St nd-by mode by pressing the OFF button
Disconnect the AC Input Volt ge for the UPS.
The gr phic LCD p nel is OFF only when the UPS is completely OFF.
If UPS is used daily, it is ecommended to leave the UPS connected to the AC Input line and use the ON/MUTE and
OFF buttons on the f ont panel to activate/deactivate the Inve te .
If the UPS has to be tu n OFF completely fo seve al days, it is ecommended to disconnect the AC Input line fo
the UPS and then p ess the OFF button.
If the ON button is p essed when AC Input line is not p esent, the UPS switches ON even, and wo ks in Batte y
mode afte some seconds.
If the OFF button is p essed when AC Input line is not p esent, then the Inve te switches OFF and consequently
the e will be no Output powe .
8.2 Low B ttery nd Autom tic Rest rt
The UPS eaches the Low B ttery condition wheneve , du ing wo king in Batte y mode, the batte ies each a
cha ge level allowing the connected devices to ope ate fo few minutes mo e.
The UPS wa ns ope ato s of Low B ttery by lighting of the LOW BATT. icon on the g aphic LCD and by emitting an
acoustic signal eve y second.
If AC Input does not come back on within few minutes, the UPS shuts-down utom tic lly thus p eventing the
batte ies f om discha ging excessively; the UPS stops supplying Output powe , deactivates cont ol panel indication
and goes to a waiting state. Once AC Input comes back on, the UPS rest rts utom tic lly and afte 4 seconds it
goes back to wo k in No mal mode.

8.3 Lo d Testing
The UPS indicates the Output Load level by g aphic LCD (on the ight side as desc ibed in the chapte 5).
When the Output load is highe then nominal value the UPS wa ns of Overlo d condition by g aphic LCD and by
acoustic ala m as desc ibed in the “Wa ning Table” and in the “T oubleshooting” chapte .
The UPS wa ns of an Ove load less than 110% by acoustic ala m.
An Ove load between 110% and 130% is accepted fo about 30 seconds and afte UPS switches automatically to the
Bypass mode.
The UPS switches immediately to the Bypass mode if the Ove load is highe than than 130%.
Once the equested powe is back within ange, the UPS switches automatically to the No mal mode.
M ke sure th t the UPS never indic tes Overlo d condition.
Do not connect lo d gre ter th n r ted v lue to the UPS (see POWER specific tions in
the ch pter “Technic l Ch r cteristics”), s this m y d m ge the unit. In this c se the
w rr nty is void.
8.4 St tic Byp ss
Du ing No mal mode functioning it is possible to switch the UPS in Bypass mode, by p essing at the same time
ON/MUTE and SELECT buttons at least 5 seconds, as explained into chapte 5.
The Bypass mode, named also St tic Byp ss, is useful while pe fo ming maintenance o se vice on the UPS.
The Static Bypass, used togethe with an exte nal Manual Bypass device, enables the use to isolate the elect onic
ci cuit y of the UPS f om the mains and f om the load, and to emove the UPS without inte upting the powe by
connecting the load di ectly to the mains.
M inten nce nd service m y only be performed by uthorized technic l personnel.
During St tic Byp ss, lo ds re fed directly from Byp ss m ins. Therefore no protection
g inst m ins disturb nces or interruptions is present.
