Connect the signal line to the terminal block.
Tighten the terminal block screws to the appropriate tightening torque of 0.5 N • m.
The terminal block is removable; remove the left and right screws if it is necessary to remove
the terminal block to connect the signal line.
Precautions for Correct Use
To remove the terminal block from the Slave Unit, loosen the left and right mounting screws
alternately. When mounting the terminal block as well, tighten the left and right screws
alternately.
If you tighten or loosen only one of the screws all the way without tightening or loosening the
other screw using an electric screwdriver, the terminal block will be distorted and cracked.
