Ambient temperature and humidity
• Panels have been reduced in size due to space-saving and miniaturization in devices and systems,
and the temperature inside the panel may be at least 10 to 15°C higher than outside the panel. Im-
plement the following measures against overheating at the installation site and in the panel, and al-
low a suf
ficient margin for the temperature.
• The Controller may not start normally if the temperature is below 0°C when the power is turned ON.
Maintain an air temperature of at least approximately 5°C inside the panel, by implementing meas-
ures such as installing a low-capacity space heater in the panel. Alternatively, leave the Controller
power ON to keep the Controller warm.
• 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 T
esting 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.
Accessibility for Operation and Maintenance
• To ensure safe access for operation and maintenance, separate the Controller as much as possible
from high-voltage equipment and power machinery
.
• Secure the minimum bending radius of the cable. Otherwise the cable may be damaged.
• Consider the physical size of USB flash drive, or SD memory card as these will be inserted in to the
mounted Sensor Controller.
