DESIGN PRECAUTIONS
Make sure to set up 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.
- Most importantly, set up the following: an emergency stop circuit, a
protection circuit, an interlock circuit for opposite movements (such as
forward vs. reverse rotation), and an interlock circuit to prevent
damage to the equipment at the upper and lower positioning limits.
- Note that when the CPU module 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 CPU module occurs in an input/
output control block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe
machine operation in such a case.
- Note that the output current of the 24V DC service power supply varies
depending on the model and the absence/presence of extension
modules. If an overload occurs, the voltage automatically drops, inputs
in the PLC are disabled, and all outputs are turned off.
External circuits and mechanisms should be designed to ensure safe
machine operation in such a case.
- Note that when an error occurs in a relay or transistor of an output
circuit, the output might stay on or off.
For output signals that may lead to serious accidents, external circuits
and mechanisms should be designed to ensure safe machine operation.
 Construct an interlock circuit in the program so that the whole system always
operates on the safe side before executing control (for data change) of the PLC
in operation. Read the manual thoroughly and sufficiently ensure complete
safety before executing other controls (for program change, parameter change,
forced output and operation status change) of the PLC in operation.
Otherwise, improper operation may damage machines or cause accidents.
DESIGN PRECAUTIONS
Simultaneously turn on and off the power supplies of the CPU module and
extension modules.

<Reference>
3.1.2 European type terminal block
1) Wire size
2) Treatment of wire ends
Strip the coating of strand wire and twist the cable core before connecting
it, or strip the coating of single wire before connecting it. An alternative
connection is to use a ferrule with insulating sleeve.
When using a wire ferrule with an insulating sleeve, choose a wire with
proper cable sheath referring to the above outside dimensions, otherwise
the wire cannot be inserted easily.
Tighten the screws to a torque of 0.22 to 0.25 Nm.
Do not tighten terminal screws exceeding with a torque outside the above-
mentioned range.
Failure to do so may cause equipment failures or malfunctions.
3) Tool
For tightening the
terminal, use a
commercially available small
screwdriver having a straight form
that is not widened toward the end
as shown right.
Note:
If the diameter of screwdriver grip is too small, tightening torque may not be
achieved. To achieve the appropriate tightening torque shown in the table
above, use the following screwdriver or appropriate replacement (grip
diameter: approximately 25 mm (0.98")).

Make sure to observe the following precautions in order to prevent any
damage to the machinery or accidents due to malfunction of the PLC
caused by abnormal data written to the PLC due to the effects of noise.
- Do not bundle the power line, control line and communication cables
together with or lay them close to the main circuit, high-voltage line,
load line or power line. As a guideline, lay the power line, control line
and communication cables at least 100 mm (3.94”) away from the main
circuit, high-voltage line, load line or power line.
- Ground the shield of the shielded wire or shielded cable at one point on
the PLC. However, do not use common grounding with heavy electrical
systems.
- Ground the shield of the analog input/output cable at one point on the
signal receiving side.
However, do not use common grounding with heavy electrical systems.
