CABLE END TREATMENT AND TIGHTENING TORQUE
• For the terminals of FX3G 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.

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.
4.2 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
below.
• Use ground wires thicker than AWG14 (2 mm²).
• Position the grounding point as close to the PLC as possible to
decrease the length of the ground wire.
