Introduction

Properties of the BaseUnits
The ET 200SP distributed I/O system offers you a rugged and service-friendly design with
permanent wiring over the BaseUnits (BU).
The BaseUnits provide the electrical and mechanical connection of the ET 200SP modules.
A wide range of BaseUnits is available to suit individual requirements.
You can place BaseUnits at any location with the ET 200SP distributed I/O system. Thanks
to the push-in connection system, you can wire the terminals without tools.
Note the following restrictions:
● The potential group based on SELV/PELV supply or the PotDis version is light-colored.
● The infeed of protective conductor via BU is not permitted.
You can find additional information on using the BaseUnit in the ET 200SP System Manual
(https://support.industry.siemens.com/cs/ww/en/view/58649293).
Note
All BaseUnits placed in a load group must match the infeed potential of the corresponding
light-colored BaseUnits.
