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

Vibration and Shock
The Controller 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 Electrotechnical Products. It
is designed so that malfunctioning will not occur within the specifications for vibration and shock. If,
however, the Controller is to be used in a location in which it will be directly subjected to regular vibra-
tion or shock, then implement the following countermeasures:
• Separate the control panel from the source of the vibration or shock.
Or secure the Controller 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, se-
cure either the source of the shock or the Controller with rubber padding.
5-5-4
Atmosphere
Using the Controller 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 Controller.
