4.5.2 Exi Applications
Some I/O modules are intended to be connected with devices located in hazardous ar-
eas. To ensure safety and reliability in these applications, several additional requirements
must be considered:
• The node structure meets the additional requirements specified below for the power
supply as well as the requirements for air and creepage distances.
• The operator obtains a prototype test certificate that confirms the correct installation of
the system and store it in a control cabinet or housing.
Observe the detailed requirements as stated in the original wording of the respective cer-
tificate (Installation Regulations Specified by Approvals).
Power Supply Requirements
Only Exi bus supply modules are permitted to be used for power supply to any node sec-
tions containing I/O modules for Exi applications.
The following Ex i potential supply modules may be used for this purpose: 750-606,
750-625/000-001.
