■ Safety Precautions
Do not touch the terminals while power is being supplied.
Doing so may possibly result in electric shock. Make sure
that the terminal cover is installed before using the
product.
Always provide protective circuits in the network. Without
protective circuits, malfunctions may possibly result in
accidents that cause serious injury or significant property
damage.
Provide double or triple safety measures in external
control circuits, such as emergency stop circuits, interlock
circuits, or limit circuits, to ensure safety in the system if
an abnormality occurs due to malfunction of the product
or another external factor affecting the product's
operation.
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 minor
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 explosion, causing minor or moderate injury, or
property damage.
Do not attempt to disassemble, repair, or modify the
product. Doing so may occasionally result in minor or
moderate injury due to electric shock.
Do not use the equipment for measurements within
Measurement Categories III and IV for K3HB-X and II, III,
and IV for K3HB-S, K3HB-V, and K3HB-H (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 Category
for which the product is designed.
Perform correct setting of the product according to the
application. Failure to do so 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 monitoring
system. Product failure may occasionally prevent
operation of comparative outputs, resulting in damage to
the connected facilities and equipment.
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 moderate
injury, or damage to the equipment.
Terminal block screws: 0.43 to 0.58 N·m
Connector locking screws: 0.18 to 0.22 N·m
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, check the nodes to confirm
safety. Changing the program or I/O memory of other
nodes may occasionally cause unexpected operation,
resulting in minor or moderate injury, or damage to the
equipment.
