NTERNAL ATTERIES
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.

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. 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 broken equipment 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 caps 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
 Check whether the battery has been inadvertently earthed. If this is the case, disconnect the source from
earth. Contact with any part of the earthed battery may cause an electric shock. The likelihood can be
reduced if the earthing connections are interrupted during installation and maintenance (applicable to
remote battery-powering and equipment, without earthing circuits).

Risk of explosion if the battery is replaced by another of the incorrect type. Refer to the following table to identify
the correct quantities and models:
For correct interconnection of the batteries, refer to the wiring diagrams available to service personnel only or to
the battery kit installation manual
