5 Setup and Wiring
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 sufficient 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 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.
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.
