Caution
!
Do not attempt to reactivate discharged batteries by heating or other means.
Batteries must not be recharged, as this can lead to leakage and/or explosion.
Failure to comply with these regulations can lead to bodily injury or material
damage.
Battery--backed SRAMs and clock chips are installed on the CCU module and
the PCU 50/70. The back--up voltage is monitored by the control and a monito-
ring signal is output. When a monitoring signal has been triggered, the battery
must be replaced within six weeks. The battery of the SINUMERIK 810D can be
replaced after disconnecting the control and removing the CCU module without
any loss of data, as the data is backed--up for a period of approx. 15 minutes.
Backup time
The backup time of the batteries used is at least five years.
The battery must be removed before the module is stored.
