AUX bus as PE bar
If you use an AUX bus as a protective conductor bar, attach the yellow-green color
identification labels to the AUX terminals, and establish a functional connection to the
central protective conductor connection.
If you stop using the AUX bus as a protective conductor bar, make sure you remove the
yellow-green color identification labels and remove the connection to the central protective
conductor connection again.
If you use the AUX bus as a protective conductor bar, the corresponding protective
conductor tests must be conducted by the installer of the system before commissioning. In
addition, both ends of the ET 200SP system assembly must be mechanically fixed to the
mounting rail in this case (e.g using 8WA1010-1PH01 ground terminals); this connection
can only be detached by using a tool.
