Use in Hazardous Environments

The

WAGO-I/O-SYSTEM 750

(electrical equipment) is designed for use in

Zone 2 hazardous areas.

The following sections include both the general identification of components

(devices) and the installation regulations to be observed. The individual

subsections of the “Installation Regulations” section must be taken into account if

the I/O module has the required approval or is subject to the range of application

of the ATEX directive.
