Appendix C Application and Wiring Examples for Safety Modules
When the module is wired as shown on page 279, 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.
• We strongly recommend that you connect separate shielded cables to the
P terminal and the N terminal to reduce possibility of a short between
these terminals. If a short is detected across the P-N pair, the module
outputs are turned off, but the actuator that is connected to the output
pair remains on.
• No Load and Overload conditions are only detectable at the P terminal.
