Danger to life through electric shock if the cutout in the protective cover has been broken
out
Live components are open and accessible if the 24 V terminal adapter or the DC link infeed
adapter are removed. Touching live components can result in death or severe injury.
• Replace the protective cover with the broken out cutouts by a new protective cover.
Note
The 24 V terminal adapter should always be installed to the left of the component located at
the far left, because if it is positioned anywhere else there may not be enough space for the
24 V plug-in jumpers.
If necessary, the 24 V terminal adapter can also be located at the right for 50 mm and
100 mm modules.
