Supplementary Power Supply Regulations

The WAGO-I/O-SYSTEM 750 can also be used in shipbuilding or offshore and
onshore areas of work (e. g. working platforms, loading plants). This is
demonstrated by complying with the standards of influential classification
companies such as Germanischer Lloyd and Lloyds Register.
Filter modules for 24 V supply are required for the certified operation of the
system.

Additional supply module for potential equalization!
Only insert another potential power terminal 750-601/602/610 behind the filter
terminal 750-626 if you need the lower power contact for potential equalization,
for example, between the shield connections and you need an extra tap for this
potential.
