DESIGN
PRECAUTIONS
• Provide a safety circuit on the outside of the PLC so that the
whole system operates to ensure the safety even when external
power supply trouble or PLC failure occurs.
Otherwise, malfunctions or output failures may result in an
accident.
1) An emergency stop circuit, a protection circuit, an interlock
circuit for opposite movements, such as normal and
reverse rotations, and an interlock circuit for preventing
damage to the machine at the upper and lower positioning
limits should be configured on the outside of the PLC.
2) When the PLC CPU detects an error, such as a watch dog
timer error, during self-diagnosis, all outputs are turned off.
When an error that cannot be detected by the PLC CPU
occurs in an input/output control block, output control may
be disabled.
Design external circuits and mechanisms to ensure safe
operations of the machine in such a case.

PRECAUTIONS
• Do not bundle the control line together with the main circuit or
power line. Do not lay the control line near them.As a rule, lay
the control line at least 100mm(3.94") or more away from the
main circuit or power line.
Noise may cause malfunctions.
• Install in a manner which prevents excessive force from being
applied to the connectors for peripheral device connections.
Failure to do so may result in wire breakage or failure of the
PLC.
Notes
• Simultaneously turn on and off the power supplies of the main
unit and extension devices.
• Even if the power supply causes an instantaneous power failure
for less than 10 ms, the PLC can continue to operate.
• If a long-time power failure or an abnormal voltage drop occurs,
the PLC stops, and output is turned off.
supply is restored, it will automatically restart (when the RUN
input is on).
WIRING
PRECAUTIONS
• Cut off all phases of the power source externally before
installation or wiring work in order to avoid electric shock or
damage of product.
WIRING
PRECAUTIONS
• Connect the AC power supply wiring to the power supply
terminal as stated in this manual.
If an AC power supply is connected to a DC input/output
terminal (connector) or power supply terminal, the PLC will be
burnt out.
• Do not wire vacant terminals externally.
Doing so may damage the product.
• The main unit requires a class D ground (grounding resistance:
2
100Ω or less), with a 2mm or larger wire used at the ground
terminal.
Do not connect the terminal to a ground wire common to a
heavy electrical system (refer to section 3.3).
• When drilling screw holes or wiring, cutting chips or wire chips
should not enter ventilation slits. such an accident may cause
fire, failures or malfunctions.
Notes
• Input/output wiring 50 to 100 m (164'1" to 328'1") long will
cause almost no problems of noise, but, generally, the wiring
length should be less than 20 m (65'7") to ensure the safety.
• Extension cables are easily affected by noise. Lay the cables
at a distance of at least 30 to 50 mm (1.19" to 1.97") away from
the PLC output and other power lines.
3.1 Cable end treatment and tightening torque
For the terminals of FX series PLC, M3 screws are used.
3U
The electric wire ends should be treated as shown below.
Tighten the screws to a torque of 0.5 N.m to 0.8 N.m.
