Functional safety: Deactivated – Activated
STO circuit deactivated
Jumper in terminal X200/1:2 (STO to P24): STO circuit is deactivated.
Here, the STO input is deactivated and the STO is therefore deselected. Converter operation
is possible independent of the signal states at the STO input.
● The converter is supplied in this state. The terminals 105 and 106 are jumpered in the
delivery state (no emergency stop).
● Applications where STO is not used.
STO circuit activated
Jumper in terminal X200 must be removed: STO circuit is activated.
Safety relay can be connected.
