WARNING!
Function test requirements of the safety function to comply with the Safety Integrity
Level SIL2 respectively with the Performance level PLd, category 3:
The safety function has to be tested (activated/deactivated) at least once a year.
The DC-link voltage must be measured in STO state once a year. The measured 
value must be  60 V.
CAUTION!
If the user calculates the safety application for the specified values with 20 years, the
device must be decommissioned after 20 years. This is the maximum life cycle time
of the device. The device must be decommissioned after this time. The device must
be properly disposed of.
It is not possible to perform a proof test.
NOTICE!
The proper condition of the controller's fan must be checked before commissioning.
The maintenance and cleaning of the fan must be made at least once a year.
on page 316) to the disconnection of the DC link is maximum 5 ms.
CAUTION!
The existing capacitance of the decentralized drive solutions BM2500 connected to
the DC link is discharged in case of active STO function. The time period for this
discharge can be significantly greater than the reaction time, depending on the
number of connected decentralized drive solutions BM2500. The discharge of the DC
link is no part of the safety function.
