Disposing of Battery Backup Units - If Applicable
WARNING
If the BBU is damaged in any way, toxic chemicals may be released. The
material in the battery pack contains heavy metals that can contaminate the
environment. Federal, state, and local regulations prohibit the disposal of
rechargeable batteries in public landfills.
Be sure to recycle the old battery packs properly. Comply with all
applicable battery disposal and hazardous material handling laws and
regulations in the country or other jurisdiction where you are using the
BBU.
WARNING
There is danger of an explosion if the battery is incorrectly replaced. Replace
it only with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
WARNING
Disconnect the power supply at the circuit breaker before accessing any
components. Turning off the system power supply switch does not reduce
the risk of electrical shock from the power supply terminal block.
