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 wiring chapter of the User Manual for more details.
2) The +24 V power supply for safety function is only for STO use and cannot be used for other purposes.
3) The RELAY terminal uses the PCB terminal block:
• 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:
• 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.

Specifications for Wiring Terminals – Main-Circuit Terminals
Notes:
• If you install at Ta 40°C above environment, please use copper wire with a 600V voltage rating and
temperature resistance of 90°C or higher.
• For UL compliant installation, you must:
1) Use 75°C temperature resistant copper wire or better. Do not reduce wire gauge when using higher
temperature wire.
2) Use the specific ring lug part listed in the table below.
3) Use crimp tool KST2000D-1322 or IZUMI 5N18 for 22
–
8 AWG wire, or
IZUMI 9H-60 for 6
–
4 AWG wire.
