SAFETY STANDARDS
1 SAFETY STANDARDS
This manual must be kept in the vicinity of the UPS, so that the operator may consult it at any time for
clarifications on the correct use of the UPS.
Read the manual carefully before connecting the unit to the general mains power supply and to the devices to be
powered.
Before putting the UPS (Uninterruptible Power Supply) into operation, the operator must be fully aware of the
functions and positions of all the controls and of the technical and functional characteristics of the system, in
order to avoid risks to persons and to the equipment.
Before starting, the unit must be provided with an equipotential conn ection as established by the safety standards in
•
force. The earth cable of the UPS is to be connected to an efficient earthing point.
If the earth connection is not made, all devices connected to the UPS will be without equipotential connection. In th is
•
case the manufacturer declines all responsibility for damage or accidents caused by non-observance of the said
standard.
In case of mains failure (battery mode), do not disconnect the input cable from mains so to ensure the earth
•
connection to the loads supplied.
All subsequent mainten ance operations must be carried out solely and exclusively by authorized personnel. Insid e the
•
system high electric voltages are generated which may endanger maintenance personnel who are not sufficiently
prepared and trained for such tasks.
If at any time during use a hazard condition is created, remove the mains power supply (if possible through the
•
distribution panel upstream of the unit) and switch the UPS off completely following the appropriate procedure.
•
When assembling and replacing the battery, the UPS should always be switched off and disconnected from the mains
power supply.
The UPS contains an internal power source which is the batteries. The UPS output ma y be powered even when the
•
UPS is not connected to the mains power supply.
•
Do not force, break or try to open the batteries. They are sealed and do not require any maintenance. Inside they
contain substances that are toxic to health and that pollute the atmosphere. Do not switch the UPS on if there is any
leak of liquid, or if a residual white powder is noted.
•
Replace the fuses ONLY with other fuses of the same type.
• The sockets can be used as output isolating devices (EPO Emergency Power Off). When installing, leave a suitable
space at the back of the UPS near the fuse holder unit for easy access to the fuse holders.
Avoid contact of the UPS unit with water or liquids in general. Do not introduce foreign bodies.
•
If the unit needs to be scrapped, it is essential to entrust the equipment solely and exclusively to specialist disposal
•
companies. These are obliged to break up and dispose of the various components in accordance with the legal
provisions in force nationally.
The UPS generates a leakage current of about 1.5mA. To guarantee the maximum limit leakage current of 3.5mA,
•
make sure that the maximum leakage curren t of the load is 2 mA. If the load leakage cur rent exceeds this limit value,
have qualified personnel connect the UPS to an industrial t ype, IEC 309 compliant power supply mains, with a current
of correct dimensions for the UPS power rating.
UPS-ENTERPRISE is intended for commercial and industrial use; it is not recommended for use in medical

2 GENERAL DESCRIPTION
UPS-ENTERPRISE: sure power supply for servers, graphics stations and network devices.
The main purpose of the UPS is to protect sensitive and critical equipment items from the electrical disturbances
that can compromise operation. Black-outs, brown-outs, variations of voltage and frequency, lightning,
electrostatic discharges and rapid overvoltages are phenomena found in all office and industrial environments
and which cause hardware damage and data losses.
2.1 OPERATION
UPS-ENTERPRISE is based on the on-line, double conversion, VFI (Voltage and Frequency Independent)
technology to guarantee the highest level of electrical protection. With this principle of operation, the voltage and
the frequency at the input of the UPS are completely regenerated via a first AC/DC conversion followed by a
DC/AC conversion in order to provide the consumer a stable waveform that is exempt of noise or distortions, and
therefore completely independent of the input mains. In this double conversion process, the UPS also becomes
a filter element in relation to the electrical network thus preventing the distorting absorption (typical of IT users)
from being reflected on the power supply line.
In the event of a black-out, UPS-ENTERPRISE provides for generation of the output voltage without any
disturbance, even transient, drawing the power from the internal batteries. During normal operation with the
mains line present, UPS-ENTERPRISE recharges the batteries fully automatically and independently.

Place the UPS on a flat and stable surface, in a ventilated environment away from heat sources and
exposure to direct sunlight.
Keep ambient temperature between 0°C and 40°C and humidity less than 90% (non-condensing); the best
temperature to guarantee longest possible battery life is 15-20°C.
Ensure that the environment that the UPS will be installed in is not dusty, and leave a space of at least 20
cm around it to allow for adequate ventilation and access to the rear panel.
Make sure not to set the UPS or any other heavy object on the cables.
Check that the voltage and frequency preset for operation is right for your electrical power supply. The UPS
data can be read on the plate on the rear panel.
For the RS232 serial connection or with a LAN network, use only the manufacturer-supplied cables and
accessories.
In case of RK models for installation in 19” standardized cabinets, the lateral brackets supplied must be
mounted.
The pictures that follow illustrate the assembly depending on the configuration.

4.2 Power Share Configuration (1500 / 2000VA version only)
Functionality of the Power Share sockets can be configured through the softwar e (Net-Vision/Uni Vision).
The purpose of this group of extra sockets is, generally speaking, to feed part of the users (those with low
priority) to be able to exclude them in critical situations and leave full availability of power supply to the privileged
users connected to the main sockets.
Possible configurations: the Power Share outlet is disconnected in case of:
• (Default) Overload on the output with mains line up or load greater than 95% in battery operation.
• Residual battery capacity < XX % (user-selectable through the software)
• Residual battery back-up time < di XX min (user-selectable through the software)
• Emergency Lighting operation (user-selectable through the software)
Emergency Lighting means activating the Power Share sockets only when the mains line is down; this is
a contrary logic function, but one which is useful for activating an emergency lights line when the mains
line is down without the need for additional circuitry.

5.1 COMMANDS AND SIGNALS
5.1.1 Switching on with mains power present
See note
After the mains power supply has been connected, the
internal battery-charger is activated automatically and the
UPS goes into by-pass mode.
Note
Under normal conditions (mains present), the associated LED may be flashing, indicating inversion of the phase
/ neutral polarities: in this case, insert the plug the other way to eliminate the problem.
Press the ON button for about 2 sec. (until you hear a
beep) to activate the UPS and power your equipment.
After a few seconds for the self-test, the LEDs will be as
shown in the figure on the left.
The mains power supply is regular and constant and the
batteries are in charging or floating. This is normal
operation.
Your application is powered by the UPS and continuous
power is guaranteed.
If the UPS is switched on with mains absent, follow the
same procedure as described above and after the self-test
the UPS will go into battery-powered operation.
The consumers are powered by the batteries, which will
progressively discharge.
An intermittent acoustic and visual alarm will indicate that
the UPS-ENTERPRISE is operating on battery power.
It is recommended to switch on in this way only if the prot ected
equipment has to be switched on under emergency conditions
and with the minimum indispensable load.
Your application is powered for the residual time given by
the batteries

5.1.2 Battery-powered operation (in cases of black-out)
DISPLAYS & CONTROL
Following a failure of the mains power supply or a
condition of mains out of the accepted limits, the UPS
goes immediately into battery-powered operation without
disturbance of the power supply to the application.
An acoustic and a visual signal show the battery
operation status.
The acoustic alarm may be muted temporarily by
pressing the “ON” button for 3 sec.
Your application REMAINS powered
In the event of a prolonged mains failure, when battery
back-up will soon run out, the imminent shutdown is
clearly signalled: “battery low” condition.
The battery LED bar is almost out, the buzzer sounds
again automatically at a more frequent rate (and can no
longer be muted).
It is recommended to close down applications manually if
the automatic shutdown procedure has not been
activated via the specific software installed on the
computer.
WARNING! your application REMAINS powered but
residual operation time is nearly out!
When the regular mains power supply returns, normal
operation is restored automatically.
Your application IS powered by the UPS with continuous
power ensured and the battery is recharged automatically.
If the black-out is not reset, the UPS provides power to
the application until the batteries are completely
discharged or until shutdown is activated through the
software.
The output is thus disconnected while awaiting the return
of the mains.
When the mains is restored, the UPS will start again
automatically.

WARNING
Where the load demands more power than the nominal
power of the UPS or if there is a peak of greater than
130%, the UPS enters bypass mode.
The UPS remains in this condition while waiting for the
required absorption to return inside the limits.
The load LED bar displays the irregular
absorption.
Your application remains powered though with potential
risks of interruption of the service or deterioration of
performance.
5.1.4 Switching the UPS off
Partial switching off with mains present
Pressing the OFF key for 2 sec. in normal operation with
mains present activates the partial switching off of the
UPS.
WARNING!
This does not lead to switching-off of the applications
connected.
This is a partial switching-off, as the microprocessor
control and battery recharging circuits are still operative
with the consumers powered by the mains through the
bypass.
Your application remains powered though with potential
risks of interruption of the service or deterioration of
performance.
Total switching-off
For total switching-off, press the OFF button for 2 sec. (as
above) and take out or disconnect the mains power
supply.
