The standard STO cable is yellow to signal “safety”, and by using this official cable, the
disable output (pin 4) is not connected inside. If using another standard cable, pin 4 might
be connected and therefore 24 V is inside the cable and could be a risk in safety applica-
tions.

Functional Proof tests
The functional safety standards require that functional proof tests be performed on the
equipment used in the system. Proof tests are performed at user-defined intervals and
are dependent upon PFD and PFH values.
IMPORTANT
The specific application determines the time frame for the proof test interval. Verify op-
eration of safety function after drive installation, modification, or maintenance.
Refer to
, page 70 for more information about how to test the
safety function.
