Safe torque off connection (inverter unit only).
Note:
This connection only acts as a true Safe
torque off input when the ZCU is controlling
an inverter unit. When the ZCU is controlling
a supply unit, de-energizing the inputs will
stop the unit but will not constitute a true
safety function.
XSTO
Connection for FSO-xx safety functions
