Ambient Temperature, Input Voltage, I/O Simultaneous ON Ratio
When the FC6A Series MicroSmart is used in an ambient temperature of 45°C or higher, reduce the input voltage and I/O
simultaneous ON ratio (a%) according to the following diagrams. However, the following diagrams show the temperature
conditions when the FC6A Series MicroSmart is normally installed.
Note: Normally installed means the state in the diagram in "Normal Installation State" on page 3-1.
The usage conditions will also change according to the installation state. For details, see "Installation Location" on page 3-1.
