Appendix C Application and Wiring Examples for Safety Modules
When the module is wired as shown on page 283, and the requirements listed
are met in the project of the safety controller, it is suitable for applications that
are rated up to, and including, Category 4 as defined in ISO 13849-1.
To achieve that suitability rating, the following requirements must be met:
• The Point Mode must be Safety Pulse Test.
• All power source cables must be installed separately, for example, with a
separate cable duct or shielded cable. Power source cables are
connections to the MOD+, SA+, or LA+ terminals.
Otherwise, a Short Circuit condition between SA+ and P can be
detected and the output is turned off but the actuator that is connected
to it remains on.
• You must connect two ground terminals. Otherwise, the maximum
residual current at signal 0 cannot be maintained if only one ground line
is connected and it is interrupted.
For more information on residual current, see the Compact 5000 I/O
Modules and EtherNet/IP Adapters Technical Data, publication
5069-TD001
