Humidity

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
EtherCAT Slave Terminal power ON at night or installing a heater in the control panel to keep it warmer.

Vibration and Shock

The EtherCAT 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 EtherCAT 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 EtherCAT 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 EtherCAT Slave Terminal with rubber padding.

Atmosphere

Using the EtherCAT 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 EtherCAT Slave Terminal.
