Wiring Precautions
• Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
• Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or product failure.
• Check the wiring to be sure it has been performed correctly.
There is a risk of product failure or malfunction.
• Install molded-case circuit breakers and other safety measures to pro-
vide protection against short circuits in external wiring.
There is a risk of fire or failure.
• In places with poor power supply conditions, ensure that the input
power is supplied within the specified voltage range.
There is a risk of equipment damage.
• Provide sufficient shielding when using the product in the following
locations.
• Locations that are subject to noise, such as from static electricity
• Locations that are subject to strong electromagnetic or magnetic fields
• Locations that are subject to radiation
• Locations that are near power lines
There is a risk of equipment damage.
• Configure the circuits to turn ON the power supply to the product
before the 24-V I/O power supply.
If the power supply to the product is turned ON after the external power
supply, e.g., the 24-V I/O power supply, the outputs from the product
may momentarily turn ON when the power supply to the product turns
ON. This can result in unexpected operation that may cause injury or
device damage.
• Provide emergency stop circuits, interlock circuits, limit circuits, and
any other required safety measures in control circuits outside of the
product.
There is a risk of injury or device damage.
• If you use MECHATROLINK I/O Modules, use the establishment of
MECHATROLINK communications as an interlock output condition.
There is a risk of device damage.
