Safety

This frequency converter offers an extended range of safety functions and thus complies with the requirements of EN 60204-1 and IEC 61800-5-2. In detail, the inverter is equipped with a Safe Torque Off (STO), a safety function to prevent unexpected start-up. This STO function corresponds to stop category 0.
