Page 8: Function Description
Fit the unit to a horizontal DIN rail. If other mounting positions are used, the switching capability values stated in the technical details cannot be maintained. There are 2 sockets on the rear of the PNOZ po4p. The base unit/control module and the expansion modules are connected using the jump- ers supplied. -
Page 9: Wiring
Adequate protection must be provided on all output contacts with capacitive and inductive loads. Do not switch low currents using contacts that have been used previously with high cur- rents. Operating Manual PNOZ po4p 1003836-EN-10... -
Page 10: Preparing For Operation
The safety functions may only be checked by qualified personnel. Status indicators LEDs indicate the status and errors during operation: LED on POWER Supply voltage is present. Channel 1 safety contacts are closed. Operating Manual PNOZ po4p | 10 1003836-EN-10... -
Page 11: Faults - Interference
Contact malfunction: As the expansion module is connected to a base unit or a control module, reactivation will not be possible if the contacts have welded after the input circuit has opened. Dimensions in mm 22,5 94 (3.70") (0.88") Operating Manual PNOZ po4p | 11 1003836-EN-10... -

Page 15: Safety Characteristic Data
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 po4p | 15 1003836-EN-10... -
Page 16: Service Life Graph
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 po4p | 16 1003836-EN-10... -
