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 DNV GL and Lloyds Register.
For standard-compliant application of Ex i XTR modules in substation
instrumentation and control, telecontrol systems or shipbuilding certified
operation, field-side power supply filters 750-624/040-001 (Field Supply Filter 24
VDC HI NC XTR) or power supply filters 750-626/040-000 (Supply Filter 24 VDC
HI XTR) are generally to be used for XTR I/O module groups

When using Ex i XTR I/O modules in shipping, station control and telecontrol
technology, the supply voltage of the “Power Supply 24 VDC Diagn for Ex i XTR
Modules” 750-606 / 040-000 must be supplied via the corresponding filter
module.
