EMC REQUIREMENTS
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.
STORAGE
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.
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.
INSTALLATION ENVIRONMENT
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

6
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).
PRELIMINARY OPERATIONS
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:
guarantee
user instruction manual
battery fuses (if battery are present).
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:

13
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.
Output breakers Selectivity
In NORMAL OPERATION : selectivity is carried out with a type Gg fuse to protect
if you want to guarantee selectivity when operating by battery ,output fuse must be installed.

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

14
WIRE CONNECTION
The following operations are to be performed with the UPS disconnected from the mains and all the
equipment switches open.
CAUTION! THE FIRST CONNECTION TO MAKE IS THE GROUNDING LEAD TO THE TERMINAL
MARKED 'PE'.
THE UPS CANNOT OPERATE WITHOUT CONNECTION TO THE GROUNDING SYSTEM.
UPS connection
Single power input
When rectifier input and bypass input share one mains input,the following picture,the jumper should be
installed before leaving factory,mains input connects IN/L1 ,IN/L2,IN/L3 ,N,loads connect
OUT/L1,OUT/L2,OUT/L3,N.
Dual power input
When rectifier input uses one mains input,bypass input uses another mains input,the jumper should be
removed between IN/L1 and BY/L1,IN/L2 and BY/L2,IN/L3 and BY/L3,one mains input connects
IN/L1 ,IN/L2,IN/L3 ,N,another mains input connect BY/L1,BY/L2,BY/L3,N.Loads connect
OUT/L1,OUT/L2,OUT/L3,N.

Check connections
After connecting the INPUT/OUT and terminal wires to the terminals of the UPS and before repositioning the
switch covers panel, check to make sure that:
all the input/output terminals are tightly screwed;
all fuse holders have a fuse inserted and are in the closed position;
the input/output protection wire (yellow/green earth wire) is correctly connected
the internal panel panel is connected to the yellow/green uni-potential cable coming from the earth bar
located on the base of the equipment.

START-UP PROCEDURE
After completing the electrical connection as indicated above and putting the internal panel into position,
proceed to start up the UPS as follows:
- Input power line
To activate all switch on the input terminal block
- Battery cabinet
To activate battery cabinet switches (first check the polarity of the connection),
- UPS
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, ups
will transfer into inverter.
FUNCTION CHECK
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 on the maintenance menu of display interface, it is possible to alter
some of the electric parameters pre-set in the factory
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)
