IV
z Precautions
WARNING
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.
CAUTION
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.
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 II, III, and IV for K3HB-R, K3HB-P, and K3HB-C
(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
V
CAUTION
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.
VI
Precautions for Safe Use
(1) Do not use the product in the following locations.
• Locations subject to direct radiant heat from heating equipment
• Locations where the product may come into contact with water or oil
• Locations subject to direct sunlight
• Locations where dust or corrosive gases (in particular, sulfuric or ammonia gas) are
present
• Locations subject to extreme temperature changes
• Locations where icing or condensation may occur
• Locations subject to excessive shocks or vibration
(2) Do not use the product in locations subject to temperatures or humidity levels outside
the specified ranges or in locations prone to condensation. If the product is installed in a
panel, ensure that the temperature around the product (not the temperature around the
panel) does not go outside the specified range.
(3) Provide sufficient space around the product for heat dissipation.
(4) Use and store the product within the specified temperature and humidity ranges. If
several products are mounted side-by-side or arranged in a vertical line, the heat
dissipation will cause the internal temperature of the products to rise, shortening the
service life. If necessary, cool the products using a fan or other cooling method.
(5) 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 result
in contact welding or burning.
(6) Install the product horizontally.
(7) Mount to a panel between 1 and 8-mm thick.
(8) Use the specified size of crimp terminals (M3, width: 5.8 mm max.) for wiring. To
connect bare wires, use AWG22 (cross section: 0.326 mm
2.081 mm
to AWG16 (cross section: 1.309 mm2) for other terminals. (Length of exposed wire: 6 to
8 mm)
(9) In order to prevent inductive noise, wire the lines connected to the product separately
from power lines carrying high voltages or currents. Do not wire in parallel with or in the
same cable as power lines. Other measures for reducing noise include running lines
along separate ducts and using shield lines.
(10) Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON.
(11) Allow the product to operate without load for at least 15 minutes after the power is
turned ON.
(12) Do not install the product near devices generating strong high-frequency waves or
surges. When using a noise filter, check the voltage and current and install it as close to
the product as possible.

(13) Do not use thinner to clean the product. Use commercially available alcohol.
(14) Be sure to confirm the name and polarity for each terminal before wiring the terminal
block and connectors.
(15) Use the product within the noted supply voltage and rated load.
VII
(16) Do not connect anything to unused terminals.
(17) Output turns OFF when the mode is changed or settings are initialized. Take this into
consideration when setting up the control system.
(18) Install an external switch or circuit breaker that complies with applicable IEC60947-1
and IEC60947-3 requirements and label them clearly so that the operator can quickly
turn OFF the power.
(19) Use the specified cables for the communications lines and stay within the specified
DeviceNet communications distances. Refer to the User's Manual (Cat. No. N129) for
details on communications distance specifications and cables.
(20) Do not pull the DeviceNet communications cables with excessive force or bend them
past their natural bending radius.
(21) Do not connect or remove connectors while the DeviceNet power is being supplied.
Doing so will cause product failure or malfunction.
(22) Use cables with a heat resistance specification of 70ºC min.

(1) Mount a surge suppressor or noise filter to peripheral devices generating noise, in
particular, motors, transformers, solenoids, and magnet coils.
(2) In order to prevent inductive noise, wire the lines connected to the terminal block
separately from power lines carrying high voltages or currents. Do not wire in parallel
with or in the same cable as power lines. Other measures for reducing noise include
running lines along separate ducts and using shield lines.

(3) If a noise filter is used for the power supply, check the voltage and current, and install
the noise filter as close to the product as possible.
(4) Reception interference may occur if the product is used close to a radio, television, or
wireless.
