(2) Heat radiation countermeasures outside the control panel
Measure the temperature at 40mm form tops of all units, and design the temperature rise so that it
is 20°C or less against the ambient temperature.
If the temperature rise at the temperature measurement position exceeds 20°C, consider adding a
fan.
Side face
The temperature of some units may rise locally, because air accumulates at a
particular point. Therefore, take a temperature measurement in each unit.
POINT
If a temperature at even one point exceeds 20°C in the temperature
measurements, take a heat radiation countermeasure such as adding fans.
