5.5.2 Ex i XTR Applications
Some I/O modules are intended to be connected to devices located in hazardous areas.
To ensure safety and reliability in these applications, several additional requirements
must be taken into account:
• The node structure must meet the additional requirements specified below for the
power supply, as well as the requirements for clearances and creepage distances.
• The operator must obtain a prototype test certificate that confirms the correct installa-
tion of the system and store it in the control cabinet/housing.
You can find the detailed requirements in the original wording of the respective certificate
(8 Installation Regulations Specified by Approvals
Power Supply Requirements
For all node sections containing I/O modules for Ex i applications, the following applies:
• Supply of the Ex i XTR I/O modules only via "Power Supply 24 VDC Diagn for
Ex i XTR Modules"
The Ex i XTR I/O modules must only be operated in conjunction with the 24 VDC
power supply (item no.: ü 750-606/040-000)!
• Do not exceed maximum current via power jumper contacts
The maximum current provided by this 24 VDC power supply is 1 A.
When configuring the system, make sure that this current is not exceeded. If it is, you
must use an additional Ex i power supply module (item no.: ü 750-606/040-000).
