Operation on safety extra-low voltage (SELV)
Make allowances for the special feature outlined below when operating the
6ES7322-5HF00-0AB0 relay output module on SELV:
The horizontally adjacent terminal of a terminal operated on SELV may not be operated at a
rated voltage higher than 120 VUC. When operated at voltages higher than 120 VUC, the
creepage distances and air gaps in the 40-pin front connector do not meet SIMATIC
requirements of safe electrical separation.
If one of two horizontally adjacent terminals is operated on SELV, the other terminal may not be
operated at more than 120 VUC.
