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.
