If the service life graphs are not accessible, the stated PFH value can be used irrespective of the switch frequency and the load, as the PFH value already considers the relay's B10d value as well as the failure rates of the other components. Operating Manual PNOZ X8P | 34 19820-EN-10... -
Page 35: Supplementary Data
To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With DC con- tactors, use flywheel diodes for spark suppression. Operating Manual PNOZ X8P | 35 19820-EN-10... -
