Wiring Procedure
A terminal cover is screwed in place on the I/O terminal block.
A label indicating the terminal arrangement is affixed to the
cover.
1. Turn off the power, and remove the terminal cover.
2. Connect the signal cables to the terminals.
Recommended
torque for
tightening the
screws
Screw terminal (M3) 0.5 to 0.6 N•m
Clamp terminal
GX90XA: 0.4N•m
GX90XP: 0.4N•m
GX90XD: 0.5N•m
3. Replace the terminal cover and fasten it with screws. The
recommended tightening torque for the screws is 0.6 N•m.
Note
With a clamp terminal, if you use a single wire whose
diameter is 0.3 mm or less, you may not be able to clamp
the wire securely to the terminal. Take measures to securely
clamp the wire such as by folding the conductor section that
will be connected to the clamp terminal in half.
