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
Profinet IO Device Terminal power ON at night or installing a heater in the control panel to keep it
warmer.
The Profinet IO Device 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 Profinet IO Device 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 Profinet IO Device
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 Profinet IO Device Terminal with rubber padding.
Using the Profinet IO Device 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 Profinet IO Device 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 Profinet IO Device Terminal as far away as possible from high-voltage (600 V or higher) and
power devices to ensure safe operation and maintenance.
