Transportation
Small drives are shipped as one unit. Larger drives are shipped in separate
transport units. All transport units are fitted with lifting lugs for a crane
that must be used to position the units.
Safety labels
Safety labels are attached to the drive doors to alert personnel of
potential hazards when working on the drive.
The standard language of the labels is English; however, other languages
can be ordered. The label design is based on the relevant ANSI and ISO
