Wiring precautions:
 The default condition is +24V / S1 / S2 shorted by jumper, as shown 1. in the Fig. 6-6. Refer to
Chapter 4 WIRING for more details
 The +24V of safety function is for STO only, as shown 2. in the Fig. 6-7, and cannot be used for other
purpose.
 The RELAY terminal uses the PCB terminal block (as shown area
○
