Operation with safe electrical extra-low voltage
When using relay output module 6ES7322-5HF00-0AB0 with safe and electrically
isolated extra-low voltage, take the following special characteristic into account:
If a terminal is operated with a safe and electrically isolated extra-low voltage, the
horizontally adjacent terminal must be operated at a rated voltage of not more
than 120 VUC. With operation at voltages greater than 120 VUC, the creepages
and clearances of the 40-pin front connector do not meet the SIMATIC
requirements for safe electrical isolation.
If one of the two horizontally adjacent termi-
nals is operated with a safe electrical extra-
low voltage, the adjacent terminal must be
operated at not more than UC 120 V.
