2.7.4  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-volt supply are required for the certified operation of the 
system. 
Item No.  Name  Description 
750-626  Supply filter  Filter module for system supply and field supply (24 V, 0 V), i.e. 
for field bus coupler/controller and bus power supply (750-613) 
750-624 Supply filter Filter module for the 24 V- field supply 
(750-602, 750-601, 750-610) 
Therefore, the following power supply concept must be absolutely complied 
with.

Note 
Another potential power terminal 750-601/602/610 must only be used behind the 
filter terminal 750-626 if the protective earth conductor is needed on the lower 
power contact or if a fuse protection is required.
