5. Set-up and maintenance
5.1 Functional testing
A check must be carried out to ensure that the projected safety function
is effective.
The security function, the configuration of the DP switch
and the jumper, as well as the proper installation, must be
checked by the responsible security expert / security officer.
5.2 Maintenance
The passive fieldbox operates error-free if installed and used properly.
6. Disassembly and disposal
6.1 Disassembly
Only disassemble the passive fieldbox if it is in de-energized state.
6.2 Disposal
Dispose of the passive fieldbox properly in accordance with national
regulations and laws.
7. Configuration
7.1 Configuration examples
3 configurations are shown respectively for the different SCHMERSAL devices. One configuration with long cable lengths (maximum),
one configuration with medium cable lengths (medium) and one configuration with shorter cable lengths (small).
The following assumptions are made for the configuration examples listed in the table:
• The examples represent maximum configurations. If individual cable lengths are shortened, larger systems are possible
• 2 x 1.5 mm² power supply wiring and 10 A fuse protection
• Use of SCHMERSAL cables
• The cable lengths listed in the table between power supply and the 1st field box, and between fieldboxes are maximum lengths.
Reducing the individual cable lengths is not critical.
