Wiring Diagrams for Safety Mode and Safety Pulse Mode
The following wiring diagrams show the input modules in Safety Mode and Safety Pulse
Mode.
A Test Output (TO) can be associated to any Safety Input (SI). One TO can only be wired
to a maximum of four SI.
In Safety Pulse Mode, if the external wiring shorts two SI from the same TO point, the
short circuit is not detectable.Therefore, connect two SI from different TO points when
in Safety Pulse Mode.
IMPORTANT:
You must use an SELV/PELV-listed power supply with the safety modules.
