6.13 Inserting I/O modules / motor starters and BU covers
Introduction
● You insert the I/O modules on the BaseUnits. The I/O modules are self-coding and type-
coded.
● You insert the PotDis-TerminalBlocks on the PotDis-BaseUnits.
● You insert the BU covers on BaseUnits whose slots are not equipped with I/O
modules/PotDis-TerminalBlocks.
● You insert the BU covers on BaseUnits whose slots have been reserved for future
expansion (as empty slots).
● The BU covers for motor starters serve as touch protection covers for unoccupied slots.
The BU covers have a holder for the reference identification label on the inside. For future
expansion of the ET 200SP, remove the reference identification label from the holder and
insert it into the final I/O module.
It is not possible to attach a reference identification label to the BU cover itself.
There are three versions:
– BU cover with a width of 15 mm
– BU cover with a width of 20 mm
– BU cover with a width of 30 mm (for motor starters)
