For this, the condition must be fulfilled that a circuit branch independent of the central processor is
available and ensures that the output stage of the converter can only be activated with external
signals. This is possible with the SFU0303.

Alternatively, a classic single-channel pulse inhibit ( section 7.8) or a dual-channel pulse inhibit in
accordance with Safe Torque Off Standard STO according to stop category 0 as in IEC 61800-5-2
( section 7.9) is possible.
Attention:
To enable the output stage of the inverter, these must be wired accordingly. The device cannot be
commissioned without these settings.
