Requirements for Clearances and Creepage Distances
For all sections of a node that contain I/O modules for Ex-i use, stricter require-
ments with regard to clearances and creepage distances apply.
• Before such a node section, the respective Power supply 24 VDC Diagn
for Ex i XTR Modules (750-606/040-000) ensures the required distance.
• After such a node section, 4 Distance Modules XTR (750-616/040-000)
must be used.
Exception: If the following section consists only of an End Module XTR
(750-600), no distance modules are required.

Do not exceed maximum current via power contacts!
The maximum current available from the "Power Supply 24 VDC Diagn for Ex i
XTR Modules" 750-606/040-000 is 1 A.
When configuring the system, ensure that this current is not exceeded.
If exceeded, an additional 750-606/040-000 must be used.

Keep the air and creep distances between intrinsically safe segments!
The maximum current available from the 750-606/040-000 "Power Supply
24 VDC Diagn for Ex i XTR Modules" is 1 A.
If the use of further 750-606/040-000 is necessary for reasons of extent of
utilization, 4 Distance Modules XTR (750-616/040-000) must be used to
guarantee the distance between the intrinsically safe segments.
