Ambient temperature (°C)
Note: 1.
The ambient operating temperature range is
−15
to 55°C, but take the following considerations into account. When the ambient
temperature exceeds 40°C, reduce the maximum load current as shown below.
2.
At least 20 mm must be provided on the left and right sides of the G3PW-A260E@. If you must use side-by-side mounting, then reduce
the maximum load current when the ambient temperature is over 30°C.
3.
Certification for safety standards was obtained with a mounting interval of 20 mm.
4.
Leave sufficient space for ventilation.
5.
Do not install the Power Controller above devices that generate significant amounts of heat, such as heaters, transformers, and high-
capacity resistors.
6.
If the ambient temperature reaches 55°C or higher, install an air conditioner to lower the temperature.
