DESIGN PRECAUTIONS
• Make sure to include 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) Above all, the following components should be included: 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 main unit detects an error during self diagnosis, such as a watchdog timer error, 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
• Observe the following items. Failure to do so may cause incorrect data-writing through noise to the PLC and result in PLC failure,
machine damage or other accident.
1) Do not bundle the control line together with or lay it close to the main circuit or power line.
Noise may cause malfunctions.
As a guideline, lay the control line at least 100mm (3.94") or more away from the main circuit or power line.
2) Ground the shield wire or shield of a shielded cable. Do not use common grounding with heavy electrical systems.
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 this 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 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.
STARTUP AND
MAINTENANCE
PRECAUTIONS
• Do not disassemble or modify the adapter.
Doing so may cause fire, equipment failures, or malfunctions.
• The adapter case is made of resin. If dropped or subjected to strong impact, the adapter may be damaged.
• When this adapter is installed or removed from the panel, make sure to externally cut off all phases of the power supply. Failure to do
so may cause malfunction or failure of this adapter.
DISPOSAL PRECAUTIONS
• Please contact a certified electronic waste disposal company for the environmentally safe recycling and disposal of your device.
TRANSPORTATION AND
STORAGE PRECAUTIONS
• The product is a precision instrument. During transportation, avoid any impacts. Failure to do so may cause failures in the product.
After transportation, verify the operations of the product.
