electronic components). The components removed must be taken to specialized collection and disposal
centers.
WARNING
Risk of electric shock and explosion. Can cause equipment damage, injury and death.
Do not dispose of the battery in a fire. The battery may explode.
Do not open or damage the battery. Released electrolyte is toxic and is harmful to skin and eyes. If
electrolyte comes into contact with the skin, wash the affected area immediately with plenty of
clean water and get medical attention.
WARNING
Risk of electric shock. Can cause equipment damage, injury and death.
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 and 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 the battery is inadvertently grounded. If it is inadvertently grounded, remove the
source of the ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock will be reduced if grounds are removed during installation and
maintenance (applicable to a UPS and a remote battery supply not having a grounded supply
circuit).
