Safety instructions for electrical connections

Insufficient degree of protection as a result of inadequate sealing of the cable entry
If the cable entry is not correctly sealed, it is possible that the drive no longer complies with
the requirements for the specified degree of protection.
If the drive is operated with an insufficient degree of protection, death, serious injury, and
material damage can result.
To maintain the drive's degree of protection, after connecting the cable, seal the cable entries
so they are air-tight immediately.
Insufficient degree of protection as a result of modifying the floor/roof panel
If you make any changes to the floor panel or the roof panel in order to modify the cable entry,
the changes may result in the drive no longer meeting the requirements for the degree of
protection shown. If there are holes in the floor or roof panel, then animals and vermin, for
example, can get into drive during operation.
If the drive is operated with an insufficient degree of protection, death, serious injury, and
material damage can result.
To maintain the drive's degree of protection, seal the holes so they are air-tight immediately
after installation.
