Ex I Xtr Use In Substation Instrumentation And Control And Telecontrol Technology Or In Marine Applications; Table 10 Filter Modules For 24 V Power Supply - WAGO 750 XTR Series System Manual

Planning
• Ensure clearance and creepage distances between intrinsically safe segments!
The maximum current provided by the supply module (item no.: ü 750-606/040-000) is
1 A. If the use of further 750-606/040-000 supply modules is required for capacity uti-
lization reasons, use four 750-616/040-000 Distance Modules to maintain the distance
between the intrinsically safe segments.
5.5.3 Ex i XTR Use in Substation Instrumentation and Control and Telecontrol
Technology or in Marine Applications
As a general rule, for standards-compliant use of the Ex i XTR I/O module in substation
instrumentation and control, telecontrol technology, railway engineering or shipbuilding-
certified operation, filter modules (item no.: ü 750-624/040-001) or supply filters (item
no.: ü 750-626/040-000) must be used.
Item No.

The following power supply concepts must be observed:
When using Ex i XTR I/O modules in shipping, substation instrumentation and control and
telecontrol technology, the supply voltage of the "Power Supply 24 VDC Diagn for Ex i
XTR Modules" (item no.: ü 750-606/040-000) must be supplied via the corresponding fil-
ter module.
