TOWER VERSION
This chapter describes the work needed to prepare the UPS for use in tower version.
WARNING: for your own safety and that of your product, it is important that you follow the instructions
given below exactly.
BEFORE PROCEEDING TO PERFORM THE SEQUENCE OF
OPERATIONS DESCRIBED, MAKE SURE THAT THE UPS IS SWITCHED
OFF COMPLETELY AND IS NOT CONNECTED TO THE ELECTRICAL
MAINS OR LOAD OF ANY KIND
Once removed from its packaging, the UPS is already prepared for installation in tower configuration.
To complete the configuration, all that is needed is to fit the two plastic covers provided on the top part of
the UPS, as described below:
the 2 covers have a snap-fit fastening system:
identify the special holes for mounting of the covers in the top part
of the UPS and, taking the utmost care, fit the covers exerting a
slight pressure (see figure to the side).
Note: as the covers are perfectly identical, they can both be fitted
in either of the areas (front/back) on the top of the UPS without
any problem.

INSTALLATION
RACK VERSION
This following describes the work needed to convert the UPS into rack version.
WARNING: for your own safety and that of your product, it is important that you follow the instructions
given below exactly.
BEFORE PROCEEDING TO PERFORM THE SEQUENCE OF
OPERATIONS DESCRIBED, MAKE SURE THAT THE UPS IS SWITCHED
OFF COMPLETELY AND IS NOT CONNECTED TO THE ELECTRICAL
MAINS OR LOAD OF ANY KIND
1 - First and foremost, remove the 4 feet on the
bottom of the UPS. Set the UPS horizontal,
taking the utmost care
and using a small,
flat blade screwdriver lift gently the pin
placed in the centre of the foot. Once raised,
take the pin out from the base of the UPS.
Repeat this sequence for the other
remaining feet. The exact sequence is
depicted in the figure to the side:
12
2 - With all the feet removed, now proceed to rotate the display mask. Slip
the keys provided into the release slots on the sides of the display mask
and exert a slight pressure, just enough to release the mask from the
UPS, as demonstrated in the drawing on the side.
3 - WARNING: The display mask is connected to the UPS by a special cable. This means that you must
extract the mask taking extreme care and avoiding violent jerks or other brusque movements, so as to
avoid possibly damaging the display and/or the UPS. DO NOT TRY IN ANY WAY TO
SEPARATE THE DISPLAY MASK FROM THE UPS.
4 - Rotate the mask by 90° in the anti-clockwise direction and fasten it to the UPS again, inserting it
gently into the housing until a slight clicking noise is heard and the mask remains in position.
5 - Rotate the UPS by 90° clockwise taking the utmost care
.
6 - At this point, with the UPS in the horizontal position, attach the handles
to the side of the UPS with the appropriate screws as depicted in the
figure to the side. (handles and screws are include in the handles kit
option)
NOTE: The UPS is compatible with assembly in standard rack cabinets of 600mm x 800mm or greater (in
depth). In rack type installation, given the weight of the UPS, use of the support brackets is
compulsory (guide with L-shape support). For the same reason, it is recommended that you install
the UPS in the bottom part of the rack cabinet.

4) Press the main switch on the front panel.
5) After a short time, the UPS comes on, the display lights, a beep sounds and the
icon blinks.
The UPS is in stand-by mode: this means that the UPS is in a minimum consumption condition. The
microcontroller is powered and performs its supervision and self-test task; the batteries are charging;
everything is ready for activation of the UPS. There is also a stand-by operating mode when in
battery-powered operation, provided the timer has been activated.
6) Connect the item(s) of equipment to be powered to the outlets on the rear of the UPS using the cable
supplied or another cable of max. length 10 metres.
WARNING: do not connect equipment that absorbs more than 10A to the IEC 10A outlets. For

The picture to the side depicts the area of the display reserved
for settings (configuration area), with the three settable
parameters in view.
How to proceed:
To enter the configuration area hold down the “SEL / SET” button for at least 2 sec.
The word “SET” lights and an arrow ( ► ) appears to the left of Frequency.
The arrow indicates the setting selected. To change the selection of the parameter to be modified,
press the “SEL / SET” button.
To change the item selected, press the “ON” button.
To exit from the configuration area, hold the “SEL / SET” button down for at least 2 sec.
POSSIBLE SETTINGS
Frequency: □ 50 Hz □ 60 Hz □ Off (frequency self-teach)
Voltage: □ 220 V □ 230 V □ 240 V
Mode: □ ON LINE □ ECO □ SMART □ STBYOFF
NOTE: For the change in configuration of output frequency to become effective, the UPS must be switched
off completely and switched on again (by the main switch).
THE PARAMETERS VOLTAGE AND OUTPUT FREQUENCY MUST BE
COMPATIBLE WITH THOSE OF THE LOAD POWERED BY THE UPS
53
USE
MODES OF OPERATION
The mode that gives the load maximum protection is ON LINE mode (default), where the energy intended
for the load undergoes a double conversion and is reconstructed on the output in a perfectly sinusoidal way
with frequency and voltage fixed by the precision digital control provided by a microprocessor fully
independently of the input (V.F.I.). *
Besides the traditional ON LINE double conversion operating mode, it is also possible to set the following
modes:
¾ ECO (LINE INTERACTIVE)
¾ SMART ACTIVE (shown on the display as “SMART”)
¾ STAND-BY OFF (shown on the display as “STBYOFF”)
For optimized efficiency, in ECO mode, the load is powered normally from the bypass. If the mains exits
from its specified tolerances, the UPS switches to the normal ON LINE double conversion operating mode.
About five minutes after the mains has returned inside tolerance, the load is again switched to bypass.
Where a user is unable to decide between the most suitable operating mode (ON LINE or ECO), he can leave
the choice to SMART ACTIVE mode in which, in relation to statistics regarding the quality of the mains
power supply, the UPS autonomously decides which mode to configure itself in.
Finally in STAND-BY OFF mode, operation is as a back-up device:
with mains line present, the load is powered down, whereas when a black-out occurs the load is powered by
the inverter through the batteries.
The output voltage rms value is fixed by precision, microprocessor control independently of the input voltage,
*
whereas the output voltage frequency is synchronised (inside a tolerance that is user-settable) with that of the input to
allow use of the bypass. Outside this tolerance range, the UPS desynchronises, adopting the nominal frequency and the
bypass cannot be used any more (free running mode).

BATTERY PACK
REPLACEMENT OF THE BATTERY PACK
As indicated in the presentation, the UPS is provided with a dedicated battery pack that permits easy
replacement of the batteries (hot swap), entirely safely for the operator, thanks to the protected connection
system.
WARNING: for your own safety and that of your product, it is important that you follow the instructions
given below exactly.
WHEN THE BATTERY PACK IS DISCONNECTED, THE LOADS CONNECTED
TO THE UPS ARE NOT PROTECTED AGAINST A MAINS FAILURE.
THE BATTERY PACK IS VERY HEAVY. TAKE ALL DUE CARE WHEN
PERFORMING SUBSTITUTION.
1 - The battery pack is located behind the front panel of the UPS. Take the
panel centrally by the sides and pull gently outwards as shown in the
figure to the side. In doing so, do not force the panel fastening pins too
much.
2 - Put the manual bypass switch located under the front panel to position
“II” (see figure to the side).
WARNING: in this condition, the load is powered by the bypass and
the display must show the message FAULT: C02.
WARNING: For proper operation of the UPS, it is recommended
that you replace the battery pack only with the UPS switched on.
3 - The battery pack is connected to the rest of the UPS by means of a
cable with terminal. See the figure on the side:
press the 2 tabs on the sides of the terminal (
) and take it out
pulling gently upwards. With your thumbs, together press the 2
fastening catches (
fingers into the slot located under the connector (
B
) and, keeping them pressed, put your index
C
).
4 - Maintaining the position described in the previous step, take out the
battery pack pulling outwards as shown in the figure to the side.
Take great care when extracting the battery pack as it is very heavy.
WARNING: the new battery pack and the one to be replaced must
contain the same number and type of batteries (see the label next to the
connector on the battery pack).
5 - Insert the new battery pack in its seat by sliding until it clicks into the
UPS. Connect the cable with terminal again to its connector, put the switch back to position “I” and
close the front panel. Make sure that the display returns to the normal display mode.

If it is possible to power down the load, switch off the
UPS and switch it on again; if the problem occurs again,
contact the service centre.
If undesired, check the position of the manual bypass
switch or status of the control inputs of an optional
contacts card.

PROBLEM SOLVING
ALARM CODES
By using a sophisticated self-test system, the UPS can check and report on the display panel any problems
and/or failures that could occur during normal operation of the equipment. In case of a problem, the UPS
signals the event by posting on the display the code and type of alarm present (FAULT and/or LOCK).
FAULT
The FAULT type reports may be divided into three categories:
¾ Failures: these are “minor” problems that do not result in the UPS stopping but they limit its
performance or prevent certain features being used.

¾ Alarms: these problems are more critical than the failures because – if they continue – they could
cause the UPS to stop, even in a very short time frame.

LOCK
The LOCK (block) type report signals are usually preceded by an alarm signal and, on account of their
importance, result in the inverter being switched off and the load being powered through the bypass line (the
procedure is excluded in case of lockouts due to strong and persistent overloads and lockouts following a
short-circuit).

* In ECO mode, the load is normally powered by the bypass. Therefore, in the presence of a load of constant power,
the current absorbed depends on the mains voltage, which may accordingly be in excess of the value allowed by the
input plug and the protection upstream.
When this situation arises, the UPS reports a failure which automatically disappears if the input voltage increases
and/or the output load is reduced.
