3.6.5 Supplementary Power Supply Regulations
The WAGO-I/O-SYSTEM 750 XTR can also be used in shipbuilding applications
and onshore/offshore installations (e.g., platforms, loading facilities), as well as in
telecontrol applications. This is possible via certification under the standards of
leading agencies such as Germanischer Lloyd and Lloyds Register.
For standard-compliant application in substation instrumentation and control,
telecontrol systems, railway technology or shipbuilding certified operation, field-
side power supply filter 750-624/040-00x or power supply filter 750-626/040-000
are generally to be used for XTR module groups.

Therefore, the following power supply requirements must be observed:
The 24 V system power supply for the fieldbus coupler/controller must be filtered
and protected against overvoltage. Therefore, the power must be supplied via
power supply filter 750-626/040-000.
The electronic power supply must only be connected via a slow blow 2 A fuse.
The 24 V field power supply systems must be protected against overvoltage.
Therefore, the power must be supplied via field-side power supply filter
750-624/040-00x or power supply filter 750-626/ 040-000.
For this potential group, only the supply module 750-612/040-000 is required for
a 230 V field power supply.
