Danger to life through electric shock if the cutout in the protective cover has been broken

If the 24 V terminal adapter or the DC link infeed adapter is removed, and you touch live

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

If necessary, the 24 V terminal adapter can also be located at the right for 50 mm and

100 mm modules.
