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.

Therefore, the following power supply concept must be absolutely complied with.

Figure 15: Power Supply Concept

Use a supply module for equipotential bonding!
Use an additional 750-601/ 602/ 610 Supply Module behind the 750-626 Filter
Module if you want to use the lower power jumper contact for equipotential
bonding, e.g., between shielded connections and require an additional tap for this
potential.
