BATTERY CABINET ITYS PRO 10-20 kVA, MASTERYS 10-160 kVA- Ref.: IOMXXXABXX00-EN 01

WARNING: Do not wear clothes and footwear which may build up electrostatic charge. Only use
an absorbent cloth dampened with water to clean the battery. Other cleaning agents may result
in the build-up of static charge or damage the battery cases.

NOTE: Use Personal Protective Equipment (PPE) when carrying out any work on the unit.

NOTE: When carrying out electrical installation, all applicable standards specified by the IEC (in
particular IEC 60364) and the electricity supplier must be observed. All national standards appli-
cable to batteries must be observed. For further information refer to 'Technical specifications'
chapter.

NOTE: Only use accessories recommended or sold by the manufacturer.

NOTE: Batteries must only be replaced with batteries recommended or sold by the manufacturer.
Batteries must only be replaced by qualified technicians.

NOTE: Before connecting the unit check it is fully compatible with the UPS model.

NOTE: If using cabinets not supplied by the manufacturers of the UPS, it is the installer’s respon-
sibility to check the electrical compatibility and the presence of appropriate protection devices
between the UPS and the battery cabinet (fuses and switches of sufficient capacity to protect
the cables from the UPS to the battery cabinet). As soon as the UPS is switched on (before clos-
ing the battery switches) the battery parameters must be verified accordingly (voltage, capacity,
number of elements, etc.) on the mimic panel menu. If the values indicated on the battery cabinet
data plate are different from those shown on the mimic panel, please correct the settings.

NOTE: Use the double insulated cables supplied with the unit to connect the UPS to the battery
cabinet.

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 the charging source prior to connecting or disconnecting battery terminals
•  Determine if battery is inadvertently earthed. 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 (applicable to
equipment and remote battery supplies without a grounded supply circuit).

WARNING: Batteries must not be connected or disconnected when current is flowing. Isolate the
circuit elsewhere first.

WARNING: Before carrying out any operations, ensure that:

•  The switches located inside the battery cabinet are open
•  The UPS is not live and all mains or battery switches are open
•  The switches upstream of the UPS are open
•  Wait approx. 5 minutes for the unit to discharge completely.

NOTE: Connect the PE ground conductor before making any other connections.

DANGER! RISK OF ELECTRIC SHOCK: Disconnect all power sources before carrying out any
operations on the unit (cleaning and maintenance, connection of appliances, etc.).

DANGER! RISK OF ELECTRIC SHOCK: After disconnecting all power sources wait approx. 5
minutes for the the unit to discharge completely.
