NTERNAL BATTERIES
CAUTION: If the UPS has INTERNAL BATTERIES, follow all the PRECAUTIONS AND SAFETY RULES listed below.

The UPS has HAZARDOUS electrical voltages inside it, even when the input and/or battery switches are off. The inside of
the UPS is protected by safety panels which should not be removed by untrained personnel. All installation and maintenance
or operations involving access inside the UPS require the use of tools and may ONLY be performed by trained personnel.

The UPS contains an internal source of energy: batteries. All terminals and sockets may be live even without connecting the
UPS to the mains supply.

The total battery voltage may be potentially dangerous: it may generate an electric shock. The battery compartment is
protected by safety panels which should not be removed by untrained personnel. All installation and maintenance of the
batteries involve access inside the UPS and require the use of tools: such operations may ONLY be performed by trained
personnel.

Replaced batteries must be considered TOXIC WASTE and treated accordingly (refer to RAEE-WEEE manual “DISPOSAL
OF THE APPLIANCE AND/OR ITS PARTS)”. Do not dispose of batteries in a fire: they may explode. Do not attempt to open
the batteries: they are maintenance-free. In addition, the electrolyte is harmful to the skin and eyes and can be toxic.

Do not turn on the UPS if it is leaking fluid or if you see a residual white powder.

Do not allow water, liquids in general and/or other foreign objects to get inside the UPS.

Do not open the battery fuse holder while the UPS is powering the load in battery operation mode. The interruption of the
battery DC may cause an electrical arc resulting in equipment failure and/or fire. In addition, if there is no mains power, the
energy to power the load is provided by the batteries, therefore opening the battery fuses would lead to the shutdown of the
load.

Follow these recommendations when working on the batteries:
 Remove wristwatches, rings and other metal objects
 Use tools with insulated handles

Wear rubber shoes and gloves
 Do not lay tools or metal objects on top of the batteries

Disconnect the charging source before connecting or disconnecting the battery terminals

When replacing batteries, use only the same type and number of batteries.
ATTENTION: Risk of explosion if batteries are replaced by an incorrect type
For correct interconnection of the batteries, refer to the wiring diagrams available to service personnel only or to the battery kit
installation manual.
B
ATTERY MAINTENANCE
WARNING: HAZARDOUS VOLTAGE INSIDE!
Never open the cover of the battery compartment for any reason. If any anomaly is noted, please
contact the service department.
In order to preserve a high level of efficiency and a good lifespan, the batteries must be periodically charged using the UPS itself.
Batteries are subject to self-discharge. If the internal batteries or the Battery Cabinets are stocked and not immediately installed, a full
charge must be performed.
In order to re-charge the batteries, it is required to connect the Battery Cabinet or the batteries internal to the UPS unit for at least
24hrs in “NORMAL MODE” or “STAND-BY CB ON”.
If a long battery stocking period is planned, please contact the service department.
