WARNING
Batteries present a risk of electric shock or burn from high short-circuit
current. Observe proper precautions.
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 can be toxic and is
harmful to the skin and eyes.
Batteries can contain HIGH VOLTAGES, and CORROSIVE, TOXIC and
EXPLOSIVE substances. Because of the battery string the output terminals
can carry high voltage even when the AC supply is not connected to the UPS.
Read the shutdown instructions carefully.
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 can do the 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 in the UPS. See more accurate
instructions on the UPS.
Before you connect or disconnect battery terminals, disconnect the charging
source by opening the corresponding battery circuit breaker.
If the battery is inadvertently grounded, 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. Keep the operating environment within the parameters stated in this
document.
