A CAUTION
1. Turn off power before wiring to minimize the risk of electrical shock.
2. Exposed conductive parts of wire can cause electrical shock. Use crimp-style terminals with
insulating sheath or insulating tape to cover the conductive parts. Also close the terminal
covers securely on the terminal blocks when wiring has been completed.
3. Operation without grounding may cause electrical shock or malfunction, Connect the ground
terminal on the S2T to the system ground.
4. Applying excess power voltage to the S2T can cause explosion or fire. Apply power of the
specified ratings described in the manual.
5. Improper wiring can cause fire, electrical shock or malfunction. Observe local regulations on
wiring and grounding.

NOTE
The size of the terminal screw is M3.5. Use an appropriate crimp-style terminal with a width of
7mm (0.27in) or less for the M3.5 screw.
