Eaton 93E Generation 2 UPS 100-200 kVA
(380/400/415V)
Batteries present a risk of electrical 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 may be toxic and is
harmful to the skin and eyes.
Batteries may contain HIGH VOLTAGES, and CORROSIVE, TOXIC and
EXPLOSIVE substances. Because of the battery string the output receptacles
may 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.
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
stored energy 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.
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 reduce the risk of a fire, connect only to a circuit that has a circuit breaker
that is rated in accordance with the national and local installation rules and
UPS installation instructions.
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.
