3.2 Cable and Terminal Tightening Torque
3.2.1 Power cable (FX3UC-4AD)
Supply the 24 V DC power to FX3UC-4AD via the power supply connector.
The power crossover cable (type "C" shown in the following table) is supplied with the FX
3UC-4AD.
To connect the power cable, refer to the User's Manual - Hardware Edition of the PLC main unit.
There are 3 types of power cables as shown in the following table. Types "A" and "B" are supplied with the
main unit, and type "C" is supplied with the input extension blocks for FX
2NC Series or the special function
blocks for FX
3UC/FX2NC Series.
The crossover cable (type "C") can skip up to 4 16-point output blocks to connect units.
If more blocks should be skipped to supply power to an input extension block, use cable type "B".
3.2.2 Cable (FX3U-4AD)
The FX3U-4AD terminal block is designed for M3 screws.
The end disposal of the cable shows blow.
Tighten the terminal to a torque of 0.5 to 0.8 N•m.
Do not tighten terminal screws with a torque outside the above-mentioned range.
Failure to do so may cause equipment failures or malfunctions.
