Wiring precautions:
1. The factory default condition is +24 V/ S1/ S2 shorted by jumper, as shown in the block 1 of the
figure above. Refer to the Figure 4-2 in Chapter 4 WIRING for more details.
2. The +24 V power supply for safety function, as shown in the block 2 of the figure above. This is only
for STO use and cannot be used for other purposes.
3. The RELAY terminal uses the PCB terminal block (as shown in the block 3 of the figure above):

Tighten the wiring with a 3.5 mm width and 0.6 mm thickness slotted screwdriver.

The ideal length of stripped wire at the connection side is 6–7 mm.

When wiring bare wires, make sure they are perfectly arranged to go through the wiring holes.
4. The control circuit terminal uses a spring clamp terminal block (as shown in the block 4 of the figure
above):

Tighten the wiring with a 2.5 mm width and 0.4 mm thickness slotted screwdriver.

The ideal length of stripped wire at the connection side is 9 mm.
