The PLC will 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 measures such as
installing a low-capacity space heater in the panel. Alternatively, leave the PLC power ON to keep the
