Connecting Twisted Wires/Solid Wires
Use the following procedure to connect the twisted wires or solid wires to the terminal block.
1 Press the flat-blade screwdriver diagonally into the release hole.
Press at an angle of 10° to 15°. If you press in the screwdriver correctly, you will feel the spring
in the release hole.
2 Leave the flat-blade screwdriver pressed into the release hole and insert the twisted wire or the
solid wire into the terminal hole.
Insert the twisted wire or the solid wire until the stripped portion is no longer visible to prevent
shorting.
3 Remove the flat-blade screwdriver from the release hole.
After you make a connection, make sure that the twisted wire or the solid wire is securely con-
nected to the terminal block.
