WARNING
Im
pairment of fault detection due to cross-circuit
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
►
Prevent cross-circuits between the connection from the test output of the Flexi
Soft module to the test input of the sender and the connection from the output of
the receiver to the safe input of the Flexi Soft module with protected or separate
cabling.
