4. FC 300 Selection
• The frequency converter constantly checks for critical levels of internal temperature, load current, high voltage on the intermediate circuit and
low motor speeds. As a response to a critical level, the frequency converter can adjust the switching frequency and/ or change the switching
pattern in order to ensure the performance of the drive.

All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
1) Terminals 27 and 29 can also be programmed as output.
2) Except safe stop input Terminal 37.
3) Terminal 37 is only available in FC 302 and FC 301 A1 with Safe Stop. It can only be used as safe stop input. Terminal 37 is suitable for category 3
installations according to EN 954-1 (safe stop according to category 0 EN 60204-1) as required by the EU Machinery Directive 98/37/EC. Terminal 37
and the Safe Stop function are designed in conformance with EN 60204-1, EN 50178, EN 61800-2, EN 61800-3, and EN 954-1. For correct and safe use
of the Safe Stop function follow the related information and instructions in the Design Guide.
