Subject to change without notice
Electrical installation and
adjustment
Prevent the occurrence of a potential difference
between the load and the protective device!
If you connect loads to the OSSDs that are not
reverse polarity protected, then you must connect
the 0 V connections for these loads and the related
protective device separately, one after the other, to
the same 0 V terminal strip. Only then is it ensured
that in the case of a fault, it is not possible for a
potential difference to form between the 0 V con-
nections for the loads and the related protective
device.
