Frequently Asked Questions

What is the maximum acceptable temperature for the wall attachment?

The maximum temperature of the wall attachment may reach +90 °C (ambient temperature +40 °C).

What is the function of input and output chokes in an ACS 100/140 system?

Input chokes reduce line current harmonics, while output chokes protect the motor by reducing voltage spikes and decreasing current leakages.
