4. SPECIFICATIONS AND WIRING
DANGER: DESIGN PRECAUTIONS
• Make sure to have the following safety circuits outside of the PLC
to ensure safe system operation even during external power supply
problems or PLC failure. Otherwise, malfunctions may cause serious
accidents.
 Most importantly, have the following: an emergency stop circuit,
a protection circuit, an interlock circuit for opposite movements
(such as normal vs. reverse rotation), and an interlock circuit
(to prevent damage to the equipment at the upper and lower
positioning limits).
 Note that when the PLC CPU detects an error, such as a
watchdog timer error, during self-diagnosis, all outputs are turned
off. Also, when an error that cannot be detected by the PLC CPU
occurs in an input/output control block, output control may be
disabled. External circuits and mechanisms should be designed to
ensure safe machinery operation in such a case.
 Note that when an error occurs in a relay, triac or transistor
output device, the output could be held either on or off. For output
signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery
operation in such a case.
• Do not bundle the control line together with or lay it close to the
main circuit or power line. As a guideline, lay the control line at least
100mm (3.94”) or more away from the main circuit or power line.
Noise may cause malfunctions.
• Install module so that excessive force will not be applied to the built-
in programming connectors, power connectors or I/O connectors.
Failure to do so may result in wire damage/breakage or PLC failure.
• Even if the AC power supply causes an instantaneous power failure
for less than 10 ms, the PLC can continue to operate.
• Even if the DC power supply causes an instantaneous power failure
for less than 5 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. When the power supply is
restored, it will automatically restart (when the RUN input is on).
DANGER: WIRING PRECAUTIONS
• Cut off all phases of the power supply externally before installation
or wiring work in order to avoid damage to the product or electric
shock.
CAUTION: WIRING PRECAUTIONS
• Connect the AC power supply to the dedicated terminals specified in
this manual. If an AC power supply is connected to a DC input/output
terminal or DC power supply terminal, the PLC will burn out.
• Do not wire vacant terminals externally. Doing so may damage the
product.
• Use class D grounding (grounding resistance of 100Ω or less) with
a wire of 2mm² or thicker on the grounding terminal of the FX3G
Series main unit. However, do not connect the ground terminal at the
same point as a heavy electrical system.
• When drilling screw holes or wiring, make sure cutting or wire debris
does not enter the ventilation slits. Failure to do so may cause fire,
equipment failures or malfunctions.
• Input/output wiring 50 to 100m (164'1" to 328'1") long will cause
almost no problems of noise, but, generally, the wiring length should
be less than 20m (65'7") to ensure the safety.
