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.

The frequency converter is protected against short-circuits on motor terminals U, V, W.
If a mains phase is missing, the frequency converter trips or issues a warning (depending
on the load).
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips
if the intermediate circuit voltage is too low or too high.
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.
