Terminals screws of terminal block for RS-485 are M3 threaded. Therefore, connect wiring by fitting a
crimped terminal suited to the terminal screws (see below) to the cable.
Tightening torque of terminals is 0.5 to 0.8 N·m. Screw terminals must be secure enough to prevent a
loose connection from causing a malfunction.
