Safety of persons
Dangerous voltage levels are present within the system. It should be opened exclusively
by qualified service personnel.
The system must be properly grounded.
The battery supplied with the system contains small amounts of toxic materials. To avoid
accidents, the directives listed below must be observed:
- Servicing of batteries should be performed or supervised by personnel

knowledgeable about batteries and the required precautions.
- Risk of explosion if battery is replaced by an incorrect type. When replacing batteries,
replace with the same type and number of batteries or battery packs. Instructions
shall carry sufficient information to enable the replacement of the battery with a
suitable recommended type.
- CAUTION: Do not dispose of batteries in a fire. The batteries may explode. Dispose
of used batteries according to the instructions.
-Do not open or mutilate batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
- CAUTION – A battery can present a risk of electrical shock and high short circuit
current. The following precautions should be observed when working on batteries:
Remove watches, rings, or other metal objects.
Use tools with insulated handles.
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of batteries.
Disconnect charging source prior to connecting or disconnecting battery
terminals.
Determine if battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded battery can
result in electrical shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance.
Failed batteries can reach temperatures that exceed the burn thresholds for
touchable surfaces
Product safety
The UPS connection instructions and operation described in the manual must be
followed in the indicated order.
UPS enclosure IP rating IP20.
CAUTION - To reduce the risk of fire, the unit connects only to a circuit provided with
branch circuit overcurrent protection for:
20A rating, for Tower 3ks models, trip curve C .
The upstream circuit breaker for Normal AC/Bypass AC must be easily accessible.
for PERMANENTLY CONNECTED EQUIPMENT, a readily accessible disconnect device shall
be incorporated external to the equipment
for PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment and
shall be easily accessible
Check that the indications on the rating plate correspond to your AC powered system

and to the actual electrical consumption of all the equipment to be connected to the
system.
Never install the system near liquids or in an excessively damp environment.
Never let a foreign body penetrate inside the system.
Never block the ventilation grates of the system.
Never expose the system to direct sunlight or source of heat.
If the system must be stored prior to installation, storage must be in a dry place.
The admissible storage temperature range is -25°C to +55°C without batteries, 0°C to
+40°C with batteries, suggest to storage the battery below 25°C.
This UPS can be used in TN/IT/TT power system
Special precautions
The unit is heavy: wear safety shoes and use vacuum lifter preferentially for handling
operations.
All handling operations will require at least two people (unpacking, lifting, installation in
rack system).
Before and after the installation, if the UPS remains de-energized for a long period, the
UPS must be energized for a period of 24 hours, at least once every 6 months (for a
normal storage temperature less than 25°C). This charges the battery, thus avoiding
possible irreversible damage.
During the replacement of the Battery Module, it is imperative to use the same type and
number of elements as the original Battery Module provided with the UPS to maintain
an identical level of performance and safety.
This is a category C2 UPS product. In a residential environment, this product may cause
radio interference, in which case the user may be required to take additional measures.

3.3 Install the Unit
Always keep 200 mm of free space behind the UPS rear panel.
Check that the indications on the name plate located on the top cover of the UPS
meets to the AC-power source and the true electrical consumption of the total load.
1. Connect the UPS input socket
to the AC-power source using
the cable of the protected
equipment.
2. Connect the loads to the UPS
using the cables.
Note: The UPS charges the battery as soon as it is connected to the AC-power source,
even if button is not pressed.
Once the UPS is connected to the AC-power source, 8 hours of charging are required
before the battery can supply the rated backup time.
