Preface
If you use the components in a hazardous area, knowledge of the applicable international and
local standards and guidelines for the design of components and systems in the specific
hazardous area is required.

Applies for the objects of the distributed I/O that do not belong to the
components for devices located in the hazardous area.
Unless otherwise specified, applies to the special potential group with
components for devices located in the hazardous area.

Note:
Devices that are connected to these Ex I/O modules may be located in
the Ex‑i area up to Zone 0/1, provided that the devices and the associ‐
ated components are also suitable.
