Wiring requirements
● Terminals P⊕, C, and NΘ are used to connect optional parts. Do not connect these
terminals to an AC power supply.
● To protect the main circuit, separate and cover the surface that may come into
contact with the main circuit.
● Do not allow unwanted objects to enter the wiring part of the terminal block.
● Do not solder the twisted conductors.
● The tightening torque may vary with terminals. Tighten terminal screws with the
specified tightening torque. You can use a torque screwdriver, torque ratchet, or
torque wrench to tighten terminal screws.
● When using an electric screwdriver to tighten terminal screws, set the electric
screwdriver to low speed to prevent damage to the terminal screws.
● Tighten the terminal screws with an angle not higher than 5°. Failure to comply
may damage the terminal screws.
