Operation without cover
In certain application cases, e.g. with a through-shaft, a cover cannot be installed. The
cover is not necessary if the system or unit manufacturer provides corresponding com-
ponents to guarantee for compliance with the required degree of protection. If this res-
ults in additional maintenance, the manufacturer has to describe this in the operating
instructions for the system or component.
