Rapid temperature changes can cause condensation to occur, resulting in malfunctioning due to
short-circuiting.
When there is a possibility of this occurring, take measures against condensation, such as leaving the
EtherNet/IP Slave Terminal power ON at night or installing a heater in the control panel to keep it
warmer.
The EtherNet/IP Slave Terminal is tested for conformity with the sine wave vibration test method (IEC
60068-2-6) and the shock test method (IEC 60068-2-27) of the Environmental Testing for Electrotechni-
cal Products. It is designed so that malfunctioning will not occur within the specifications for vibration
and shock. If, however, the EtherNet/IP Slave Terminal is to be used in a location in which it will be
directly subjected to regular vibration or shock, then implement the following countermeasures:
• Separate the control panel from the source of the vibration or shock. Or secure the EtherNet/IP Slave
Terminal and the panel with rubber padding to prevent vibration.
• Make the building or the floor vibration-resistant.
• To prevent shock when other devices in the panel such as electromagnetic contactors operate,
secure either the source of the shock or the EtherNet/IP Slave Terminal with rubber padding.
Using the EtherNet/IP Slave Terminal in any of the following locations can cause defective contact with
connectors and corrosion of components. Implement countermeasures such as purging the air as
required.
• In locations exposed to dust, dirt, salt, metal powder, soot, or organic solvents, use a panel with an
airtight structure. Be careful of temperature increases inside the panel.
• In locations exposed to corrosive gas, purge the air inside the panel to clear the gas and then pres-
surize the inside of the panel to prevent gas from entering from outside.
• In locations where flammable gas is present, either use an explosion-protected construction or do not
use the EtherNet/IP Slave Terminal.
When installing or wiring devices, make sure that there will be no danger to people and that noise will
not interfere with electrical signals.
Install the EtherNet/IP Slave Terminal as far away as possible from high-voltage (600 V or higher) and
power devices to ensure safe operation and maintenance.
