3.1.1 Cable end treatment and tightening torque
For the terminals of FX 3G series PLC, M3 screws are used.
The electric wire ends should be treated as shown below.
Tighten the screws to a torque of 0.5 to 0.8 N m.
•
Do not tighten terminal screws with a torque exceeding the
regulation torque.
Failure to do so may cause equipment failures or malfunctions.
• When one wire is connected to one terminal

3.1.2 Removal and installation of quick-release terminal
block
Removal Unscrew the terminal block mounting screw [both right
and left screws] evenly, and remove the terminal block.
Installation Place the terminal block in the specified position, and
tighten the terminal block mounting screw evenly [both
right and left screws].
Tightening torque 0.4 to 0.5 N m
•
Do not tighten the terminal block mounting screws with
a torque exceeding the regulation torque.
Failure to do so may cause equipment failures or
malfunctions.
* Pay attention so that the center of the terminal block
is not lifted.

3.3 Grounding
Ground the PLC as stated below.
• Perform class D grounding. (Grounding resistance: 100 Ω or less)
• Ground the PLC independently if possible.
If it cannot be grounded independently, ground it jointly as shown
100 to 240V AC
below.
