3.3 Installation
Removal
The transport eyebolts can be unscrewed and removed. Depending on the length of the
cabinet or transport unit, the support rails can have a varying number of fastening screws.
These must be unscrewed and removed before the rails can be removed.
Careful handling of the support rails
The support rails are heavy and must be removed very carefully.
Screws can fall into the unit as it is disassembled and cause serious damage when the
equipment is started up.

After removing the crane transport aids, the transport eyebolts or the fixing screws of the
mounting rail that have been removed must be replaced by the original roof screws from the
accessories pack supplied in order to ensure compliance with the degree of protection and
proper grounding of the cabinet.
