5.4.5 Wiring terminal modules
Introduction
The ET 200S distributed I/O system incorporates terminal modules both for power modules,
electronic modules and COMPACT modules:
• In the case of the terminal modules for power modules, you connect the supply/
• Terminal modules for electronic modules connect the ET 200S with the process.
• With the terminal modules for electronic modules you can connect cable shielding by
• For terminal modules for COMPACT modules, connect:
Requirements
• You must wire the terminal modules with the supply/load voltage switched off at the
• For terminal modules for COMPACT modules with you must wire up with the supply
• Follow the wiring rules.
Required tools

Wiring terminal modules for power modules
The terminal assignment of the terminal module depends on which power module is
inserted. You can find information regarding the terminal and power modules in the
device manual.
