•
Never tamper with or block the vents of batteries. Damaged or
clogged vents may result in an explosion due to excessive internal
pressure. Such an explosion could short circuit other battery
modules, result in a fire, injure personnel, or cause damage to
equipment.
•
Never charge a battery that is visibly damaged or frozen (typically
at temperatures less than -40°C or -40°F).
•
Do not disconnect the circuit at the battery terminals while the
battery is being discharged or charged.
•
Isolate the battery string from any power source or load before
making or removing connections at the battery terminals. If there
are no devices (fuses, circuit breakers, or disconnect switches) for
opening the circuit, here are some suggested procedures:
–
Make sure the free end of any wire to be connected to the
batteries is insulated until it is ready to be connected to the load
or charger or immediately after being disconnected from the
load or charger.
–
Connect to the battery terminals first before connecting to the
load or charging system.
–
Disconnect at the load or charger first before disconnecting at
the battery terminals.
Lucent Technologies recommends not making connections to the
battery terminals while the circuit is attached to a power source or
load. However, Lucent is aware that some applications may require
personnel to perform this function to avoid interruption of service. If a
situation exists where it is necessary to make connections without
isolating the battery as stated above, refer to the “Battery
Replacement” procedure in Section 8, Maintenance.
This procedure must only be performed by qualified personnel who
understand the procedures and the risks involved, have read and
understand the safety precautions, and have the proper tools and
personal protection equipment and clothing.
