Note:
A maximum number of 16 switching actuations per minute
applies to the internal contactors K1 and K2.
The number of switching actuations (service life of the contact
elements) is 1 million for HVR and HVE units, however only if
the contactor is switched current less. If switched in loaded
condition (e.g. when emergency stop is released), the number
of switching actuations for both unit families and types of
contactors is 400.000.
