ATTENTION
This manual contains instructions concerning the installation and putting into operation of the
UPS. Read the manual carefully before carrying out installation, which must be done by a
trained person.
Because this manual contains essential information on the usage of the equipment, it must be
kept in a safe place and consulted before operating on the UPS.
SAFETY REGULATIONS
The ups must not be used unless it is connected to earth
The first connection to make is the connection between the grounding lead and the
terminal indicated with the symbol:
All maintenance operations inside the ups must be carried out only by trained personnel.
High voltages are present inside the equipment even when the input and battery switches are
open
If it is necessary to replace the fuses, they must be replaced with other fuses of the same type
(consult paragraph “set output wire connection”).
To interrupt the power supply to the utilities in dangerous conditions, open all the switches
located behind the front door, or switch on the" system off " command on the ups from the
control panel.
THE BATTERY SHOULD BE CHANGED IF NECESSARY ONLY BY QUALIFIED
PERSONNEL. TO ELIMINATE REPLACED PARTS IT IS OBLIGATORY TO DELIVER
THEM TO ONE OF THE SPECIAL CONSORTIUMS FOR DISPOSAL BY RECYCLING.
THE BATTERIES ARE CLASSIFIED TOXIC WASTE BY LAW.
The Company reserves the right to make changes to the product described in this manual at
any time and without notice for reasons of improvement.

Uninterruptible Power Supply (UPS) "UPS" models, marked CE and used following the
instructions listed below, have the essential requirements to comply whit the EMC
directive 89/336 e 92/31 a 93/68 ECC.
Usage instructions
The "UPS" are UPS dedicated to a professional usage in an industrial and commercial
environment.
The connection to "REMOTE" and "RS232" connectors must be done by means of a
shielded cable.
WARNING: The " UPS " standard is a Class A-UPS Product.
In a domestic environment, this product may cause radio interference, in which
case, the user may be required to take additional measures.
For instance: in case of disturbances received by a radio or a television set, the UPS
shall be moved in order to increase the distance from above mentioned devices.
EMC REQUIREMENTS
STORGE

The area used to store the equipment must have the following characteristics:
Temperature: 0°-40°C (32°-104°C)
Relative humidity: 95% max
Only for UPS with internal BATTERIES.
The batteries contained in the UPS are subject to self-discharging.
If the UPS is not immediately installed is necessary to take note of the batteries date recharge printed on the
label fixed to the packing case(the date is present only if the UPS contains to its inside batteries), and provide to
it recharges within such date.
To recharge batteries just power up the UPS and leave it on NORMAL OPERATION for at least 24 hours.
When choosing a suitable installation room, take note of the following:
 avoid dusty areas, or other kinds of dust in air.
 check that the floor is strong enough to support the weight of the UPS and the battery cabinet (see
paragraph "DIMENSIONS AND WEIGHTS")
 avoid rooms that are too narrow as this could make normal maintenance operations difficult
 check the ambient temperature when the UPS is running. It should be between 0 and 40°C
The UPS is able to function in an ambient temperature of between 0 and 40°C. The
recommended operating temperature for the UPS and the batteries is between 20 and 25°C. In
fact, the average operating life of the batteries is 4 years at an operating temperature of 20°C,
but if the operating temperature is increased to 30°C the life is halved.
 do not position the machine in areas exposed to direct sun light or hot air.
In order to keep the temperature of the installation room within the field of values mentioned above, it will be
necessary to install a system for eliminating dissipated heat (the value of the kcal/kW/B.T.U. dissipated by the
UPS is indicated in the paragraph "SPECIFICATIONS”).
The following methods can be used:
 natural ventilation;
 forced ventilation, recommended if the exterior temperature is lower (e.g. 20°C) than the temperature at
which you wish to run the UPS (e.g. 25°C);
 air conditioning system, recommended if the exterior temperature is higher (e.g.s.30°C) than the
temperature set for running the UPS (e.g.s.25°C).
CHECK THE PACKING CASE
When you receive the UPS check that the packing case has not
been damaged during transportation.
Check that neither of the two anti-shock devices fixed to the
packing case has become red. If this has happened follow the
instructions given
on the packing case.
Be careful when
removing the
packing materials
so as not to
scratch the UPS
cabinet.
The equipment
must be handled with care as it could be damaged if it is dropped
or banged.
The UPS is delivered with:

POSITIONING
You should bear in mind the following points when positioning the UPS:
 a space of at least one metre must be kept in front of the machine to leave plenty of room for maintenance
operations.
 a space of at least 20 cm. must be left between the back of the UPS and the wall so as not to block the flow
of air from the fans, and at least 40 cm. for maintenance operations on the fans.
 no objects must be placed on the top of the machine.
The AC-DC INPUT/OUTPUT cables may enter from the bottom or from the back of the UPS.

UPS Input.
When selecting the protections to install at the input of the continuity group, you must take into consideration the
maximum current absorbed in the two operating conditions:
 In "NORMAL OPERATION", from the main line via the rectifier, the “max input current” is the one indicated
in the table. The automatic breaker is present at the rectifier input, as shown in the table, "SWIN".
 In "BY-PASS OPERATION", straight from the by-pass line, the max. value of the current is restricted by
intervention of the “automatic breaker SWBY”.
UPS output, Short circuits and selectivity
Nominal current, Input/output from the UPS is the one indicated in the table "output current".
Short circuit
When a fault occurs on the load, i.e. a short circuit, the UPS protects itself by restricting the value and the
duration of the supplied current (short circuit current). These values also depend on the operating status of the
unit at the time of the fault. We must distinguish between two situations:
 UPS in NORMAL OPERATION
the load is immediately switched onto the by-pass line, guaranteeing, before the fuses intervene, the
circuit current values indicated in “SPECIFICATION BY_PASS LINE” paragraph.
 UPS in BATTERY OPERATION
The UPS protects itself by supplying an output current approximately double the nominal current for
0,1s.
Selectivity
In NORMAL OPERATION selectivity is carried out with a type gG fuse indicated in the line one of the table
if you want to guarantee selectivity when operating by battery also see the line two of the table.

SETTING UP THE INPUT/OUTPUT WIRE CONNECTION

Leakage current circuit breaker
In the standard version, where there is no separation transformer on the by-pass line, the neutral output from the
mains
is connected to the output from the UPS.
*When input neutral connected to output neutral, the electrical systems located upstream and
downstream of the ups are identical
When operating in the presence of mains voltage, a differential breaker installed at the input intervenes because
the output circuit is not isolated from the input circuit.
When operating without mains voltage (battery feeding) the input differential breaker intervenes only if it is able
to switch on as a result of leakage current without voltage at its poles (for example a differential with an auxiliary
relay is not suitable).
The differential switch located upstream must have the following characteristics:
 a minimum differential current of 300mA (to avoid inappropriate
interventions)
 class A or class B
 delay greater or equal to 0,1s

REMOTE CONTROL AND SIGNALS
After open the left side of panel can connect to remote control and RS232 communication line:
On the connector below input fuse there are:
1. DB 15-pin female marked REMOTE.
2. DB 25-pin male marked RS232.
15-pin female marked REMOTE.
Nr. 1 aux power 12Vdc 80mA(max)
Nr. 3 Common Contact
Nr. 2 Controls for turning off INVERTER and UPS.
The pin arrangement of the connector is as follows (see figure
opposite):
BATTERY LOW
BATTERY DISCHARGING
BY-PASS/FAULT
The contact positions shown are without alarm (NORMAL
OPERATION).
The relay contacts can carry a current of 0.5A-42V.
REMOTE COMMANDS
Two commands are available as follows:
BY-PASS with STOP INVERTER command. Connecting pin 8 to
pin 15 (after at least 2 seconds).
UPS LOCKUP command. Connecting pin 7 to pin 15 (after at
least 2 seconds).
BY-PASS with STOP INVERTER
1. If the UPS receives the STOP INVERTER command when it is in "NORMAL OPERATION" mode, it
switches the load supply onto the BY-PASS line (load unprotected from any mains failure).
2. If the UPS receives the STOP INVERTER command when it is in "EMERGENCY OPERATION" mode, it will
switch itself off (load not fed)
In the two versions seen, if the jumper is maintained when the mains power returns the UPS will continue
operating on the by-pass line. However, if the jumper has been removed, the UPS will start up again in NORMAL
OPERATION mode
SYSTEM OFF
If the UPS receives the “SYSTEM OFF” command it will cut off the output voltage. LOAD NOT FEED.
To start up the UPS again, can be recover to normal operation mode by pressed buttons 8 in the control panel.
Re-activation when the system shut down completely, will recover to the operation mode before shut down UPS,
so you must use the control panel buttons 8 to cut to
normalmode. To start up the UPS again, open and close SWBY switch(reset).
25-pin male marked RS232.
The transmission protocol pre-set at the UPS factory is as follows: 9600 baud, ‑no parity, ‑8bit, ‑1 bit of stop
Transmission speed can be changed from 1200 to 9600 baud (baud on the CUSTOMISE menu on the panel).
Recommended transmission speeds for various distances are as follows:
9600(baud) 50m
4800 100m
2400 200m
1200 300m

To activate the following UPS switches:
 SWIN Input switch,
 SWBY By-pass line switch,
 SWOUT Output switch.
NOTE: the SWMB switch must be left open during normal operation. The SWMB is closed only in order to
directly feed the mains load excluding the UPS, e.g. for maintenance purposes
After you have carried out the above-mentioned operations, you will hear the hum of the fans immediately, and
for about one minute, the noise of the buzzer,ups will transfer into inverter.
After completing the start-up operations and waiting for at least four hours to allow the batteries to charge, with
the UPS in normal operation,open the input switch, input status light on the flow chart of LCD display will become
gray. the discharging indicates window of the battery will become green, checking output of ups is normal, in this
condition, turn off the mains input, then battery offers power to UPS. After several minutes, close the input switch,
ups will be back into normal status, the indicating window of AC input on the display panel will become green.
Meanwhile , the re-charging of the batteries will happen automatically.
CUSTOMISATION
By inserting the access code 436215 (from the main MENU press “button 3” "COMMANDS" and then “button 5”
“CUSTOMISING" ), it is possible to alter some of the electric parameters pre-set in the factory, within a certain
field.
It is possible to customise the following values:
- value of the NOMINAL OUTPUT VOLTAGE,
- voltage field and the frequency of acceptance on the BY-PASS line,
- BATTERY parameters, pre-alarm for final battery discharge,
- power shut-off lower than a set value (AUTO-OFF power),
- daily scheduled shut-off (AUTO-OFF time)
- RS232 port,
- identification number of the UPS.

BLOCK DIAGRAM COMPONENTS
The UPS consists of the following subassemblies:
RECTIFIER
Convert the input AC power to DC, the function is:
- powering the inverter with direct current.
- charging the battery automatically. Battery charging is done in two phases: the first phase supplies 80% of
power with limited current (recharging current) and growing voltage. The second supplies the remaining
20% of the charge with steady voltage (holding).
Recharging current is automatically limited to 15% of the capacity in Ah contained in the memory. This
recharging current imposed applies only when the total power delivered to the battery and the load does not
exceed maximum 110% of Pn.
EXTERNAL BATTERY
Provides the reserve energy for powering the load when there is no power input to the UPS.
HARMONIC REDUCTION FILTER (optional)
The filter is positioned to the entry of the rectifier, allows to reduce the input harmonic distortion of the input
current. It is composed by two inductors and by a group of capacitors. The filter is protected in entry with some
fusible.
INVERTER
Converts direct voltage from the RECTIFIER or BATTERY into stabilized sinusoidal alternating voltage. It is
always in operation and the load connected to the output of the UPS is always powered by the INVERTER.
STATIC SWITCH
This device allows the instantaneous automatic or manual switching of the power feed from the secured line
INVERTER output to an unsecured line BY-PASS line or vice versa.
The STATIC SWITCH is supplied with a device, “BACKFEED PROTECTION” that prevents the danger of
current returns on the reserve line, in the case of Mains power failure due to a break on the SCR.
MAINTENANCE SWITCH (SWMB)
Maintenance switch, by closing the SWMB and opening the other switches SWIN, SWBY, SWOUT the UPS is
excluded, maintaining the output feed.
This operation is necessary when you have to carry out maintenance operations inside the equipment, without
being obliged to interrupt the power feed.
With the SWMB closed and all the other switches open, there is no voltage inside the equipment (voltages are
present only in the terminal board area and in the switches area, N.B. in the three phase output version the
neutral conductor is not interrupted!).
When the maintenance operations are concluded restart the UPS: close SWIN, SWBY, SWOUT and then
open SWMB. The UPS will return to NORMAL OPERATION.
NORMAL OPERATION
MAINS present, equipment powered. The switches SWIN, SWOUT, SWBY are closed. SWMB is open.
