Clearance and Creepage Distance Requirements
For all sections of a node that contain I/O modules for Ex i use, stricter requirements re-
garding clearances and creepage distances apply. Before the first such node section, the
respective Ex i supply module (750-606 or 750-625/000-001) ensures the required dis-
tance.
After each such node section, four distance modules (750-616) must be used. This also
applies when the next section also starts with an Ex i supply module (750-606 or
750-625/000-001).
Exceptions:
If the following section consists of an end module for bus extension (750-627), one
distance module (750-616) is sufficient.
