!Caution
Install the EtherNet/IP Slave Units securely using M5 screws and tighten them
to a torque of 1.47 to 1.96 N·m. Do not over tighten the screws. Doing so may
damage them.
!Caution
Do not use the EtherNet/IP Slave Units where they would be continually sub-
jected to water or water spray.
!Caution
Take appropriate measures to ensure that the specified power with the rated
voltage is supplied in places where the power supply is unstable, or imple-
ment safety measures using a voltage monitor.
!Caution
Tighten the screws on the switch cover to a torque of 0.4 to 0.5 N·m. The
specified degree of protection may not be achieved if the screws are loose.
!Caution
When attaching the switch cover, wipe it clean of dust, dirt, contamination,
water, and other matter before attaching it. The specified degree of protection
may not be achieved if the cover is not clean.
!Caution
Use the specified connectors and cables for wiring.
!Caution
Do not bend the cable past its natural bending radius and do not pull on the
cable with excessive force.
!Caution
Use the specified DC power supply.
!Caution
Do not exceed the specified communications distance or the specified num-
ber of nodes.
!Caution
Do not use organic solvents to clean the EtherNet/IP Slave Units. They may
dissolve or discolor the surface.

Application Precautions
Observe the following precautions when using the EtherNet/IP Slave Units.
• Do not attempt to disassemble, repair, or modify the EtherNet/IP Slave
Units.
• Do not drop any Unit or subject any Unit to excessive shock or vibration.
Otherwise, Unit failure or malfunction may occur.
• Tighten connector screws securely.
• Separate the communications cables from the power lines or high-voltage
lines.
• Check wiring and switch settings completely before turning ON the power
supply.
• Make sure that the power supply voltage, terminal polarity, communica-
tions paths, power supply wiring, and I/O voltages are within specifica-
tions. Mistakes in any of these can cause EtherNet/IP Slave Unit failure.
• Turn OFF the power supply to the PLC and all slaves and turn OFF all
communications power supplies before connecting or disconnecting com-
munications cables.
