Do not move the battery cabinets with batteries inside if the sheet plates are
not installed.
Before you start any installation or service work, make sure that all AC and
DC power sources are disconnected. Power may come from multiple sources.
Also ensure system grounding / protective bonding continuity.
In a parallel system, the output terminals may be energized even when the
UPS is turned off.
Batteries can present a risk of electrical shock or burn from high short-circuit
current.
Electric energy hazard. Do not attempt to alter any battery wiring or
connectors. Attempting to alter wiring can cause injury.
Do not open or mutilate batteries. Released electrolyte may be toxic and is
harmful to the skin and eyes.
IMPORTANT: The battery may consist of multiple parallel strings. Make sure
that you disconnect all strings before installation.
CAUTION
Only qualified service personnel knowledgeable of batteries and the required
precautions are allowed to perform installation or service work on batteries.
Keep unauthorized personnel away from the batteries. Before you install or
replace batteries, consider all the warnings, cautions, and notes concerning
appropriate handling. Do not disconnect the batteries when the UPS is in the
Battery mode.
Make sure that your replacement batteries are of the same number and type
as the battery that was originally installed.
Before you connect or disconnect battery terminals, disconnect the charging
source by opening the corresponding battery circuit breaker.
Check if the battery is inadvertently grounded. If it is, remove the source of
the ground. Contacting any part of a grounded battery can cause a risk of
electric shock. If you disconnect the grounding connection before you work on
the batteries, the risk of an electric shock is less likely.
Dispose of batteries according to your local disposal requirements.
Do not dispose of batteries in a fire. When exposed to flame, batteries may
explode.
To ensure proper cooling airflow and to protect personnel from dangerous
voltages inside the unit, keep the UPS door closed and the front panels
installed.
Do not install or operate the UPS system close to gas or electric heat
sources.
