WARNING
Do not touch the terminals while power is being supplied. Doing so may occasionally
result in minor injury due to electric shock.
Do not touch the terminals or the electrical components or patterns on the PCB within 1
minute after turning OFF the power supply. Doing so may occasionally result in minor
injury due to electric shock.
Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from
installation to enter the product. Doing so may occasionally result in electric shock, fire, or
malfunction.
Do not use the product in locations where flammable or explosive gases are present.
Doing so may occasionally result in minor or moderate explosion, causing minor or
moderate injury, or property damage.
Tighten the screws on the terminal block and the connector locking screws securely using
a tightening torque within the following ranges. Loose screws may occasionally cause fire,
resulting in minor or or moderate injury, or damage to the equipment.
T
Perform correct setting of the product according to the application. Failure to do so is may
occasionally cause unexpected operation, resulting in minor or moderate injury, or
damage to the equipment.
Ensure safety in the event of product failure by taking safety measures, such as installing
a separate overheating alarm system. Product failure may occasionally prevent control
operations or alarm output, resulting in damage to the connected facilities and equipment.
Do not use the equipment for measurements within measurement categories II, III, or
IV(according to IEC61010-1). Doing so may occasionally cause unexpected operation,
resulting in minor or moderate injury, or damage to the equipment. Use the equipment for
measurements only within the measurement categories for which the product is designed.
The service life of the output relays depends on the switching capacity and switching
conditions. Consider the actual application conditions and use the product within the rated
load and electrical service life. Using the product beyond its service life may occasionally
result in contact welding or burning.
Make sure that the product will not be adversely affected if the DeviceNet cycle time is
lengthened as a result of changing the program with online editing. Extending the cycle
time may cause unexpected operation, occasionally resulting in minor or moderate injury,
or damage to the equipment.
Before transferring programs to other nodes or changing I/O memory of other nodes,
