the installer has to provide the correct dimensioning of the power supply and cable connection between the instruments and the loads.
Depending on the model, the maximum current in the common terminals 1, 3 and 5 is 12 A. When using the controller at maximum
operating temperature and full load, use cables featuring a maximum operating temperature of 105 °C at least.
