• The grounding wire size should be AWG 14 (2 mm2).
• The grounding point should be close to the PLC, and all grounding wire should be
as short as possible.
4. Specification

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 con-
trol may be disabled.
Design external circuits and mechanisms to ensure safe operations of the
machine in such a case.
3) When some sort of error occurs in a relay, triac or transistor of the output unit/
block, output may be kept on or off.
For output signals that may lead to serious accidents, design external circuits
and mechanisms to ensure safe operations of the machine.
