    Installation at high altitudes At altitudes higher than 6,500 ft [2 km], please contact Danfoss Drives regarding PELV. The voltage of the adjustable frequency drive is dangerous whenever connected to line power.

  • Page 9: Avoid Unintended Start

    An electronic fault, temporary overload, a fault in the line supply, or lost motor connection may cause a stopped motor to start. The FC 300 with Safe Stop (i.e., FC 301 in A1 enclosure and FC 302) provides protection against unintended starts if the Safe Stop Terminal 37 is on low voltage level or disconnected.
