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 safety function, the DIP switch configuration and
correct installation must be checked by the responsible
safety specialist / safety representative.
5.2 Maintenance
If installed correctly and used as intended, the passive distribution
module requires no maintenance.
6. Disassembly and disposal
6.1 Disassembly
The passive distribution module may only be removed when
de-energised.
6.2 Disposal
The passive distribution module is to be disposed of in the correct
manner as per the national regulations and legislation.
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
• 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 module as well as between the modules are maximum lengths.
Reducing the individual cable lengths is not critical.
