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 750-624/040-001 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:

Figure 21: Power Supply Concept

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.
