DESIGN
PRECAUTIONS
•Make sure to have the following safety circuits outside the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) 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).
2) 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 main unit 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 cases.
DESIGN
PRECAUTIONS
•Make sure to observe the following precautions in order to prevent any damage to
the machinery or accidents due to abnormal data written to the PLC under the
influence of noise:

PRECAUTIONS
•Make sure to have the following safety circuits outside the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) 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).
2) 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 main unit 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 cases.

3.2 Grounding
WIRING
PRECAUTIONS
•Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.
WIRING
PRECAUTIONS
•Perform class D grounding (grounding resistance: 100Ωor less) to the
grounding terminal on the FX3U-ENET-ADP with a wire of cross-sectional
area 0.5 to 1.5mm2.
Do not use common grounding with heavy electrical systems (refer to the
Section 3.2).
•When drilling screw holes or wiring, make sure that cutting and wiring debris
do not enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
•Make sure to properly wire to the terminal block (European type) in
accordance with the following precautions.
Failure to do so may cause electric shock, equipment failures, a short-circuit,
wire breakage, malfunctions, or damage to the product.
- The disposal size of the cable end should follow the dimensions described
in the manual.
- Tightening torque should follow the specifications in the manual.
- Twist the end of strand wire and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires
of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected
parts are directly stressed.
•Make sure to observe the following precautions in order to prevent any
damage to the machinery or accidents due to abnormal data written to the
PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main
circuit, high-voltage line or load line.
Otherwise, noise disturbance and/or surge induction are likely to take
place. As a guideline, lay the control line at least 100mm (3.94") or more
away from the main circuit or high-voltage lines.
2) Ground the shield wire or shield of the shielded cable at one point on the
PLC. However, do not use common grounding with heavy electrical
systems.

DESIGN
PRECAUTIONS
•Make sure to have the following safety circuits outside the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) 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).
2) 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 main unit 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 cases.

STARTUP AND
MAINTENANCE
PRECAUTIONS
•Do not touch any terminals or connector while the PLC's power is on.
Doing so may cause electrical shock or malfunctions.
•Before cleaning or retightening screws, externally cut off all phases of the power
supply. Failure to do so may cause malfunction or failure of the special adapter.
When the screws are tightened insufficiently, they may fall out and cause a
shortcircuit or malfunction. When tightened too much, the screws or the special
adapter may be damaged, resulting in short-circuit, or malfunction.
• When controlling the PLC (especially when changing data, the program or
changing the operating conditions) during operation, ensure that it is safe to do so.
