Putting into operation
Prior to putting the mounted entry

into operation, the correct mounting shall be
checked in accordance with these operating
and mounting instructions and any other
applicable regulations.
In locations where they are particularly at
risk, the entries shall be safeguarded
against being torn out of the apparatus or
enclosure walls by external mechanical
influences (e.g. by fork lift trucks, by
knocking or similar).
