Removal
The crane 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.
WARNING
Danger of an accident occurring due to improper handling of carrying rails
The improper handling of heavy carrying rails during disassembly can cause injuries or
material damage.
• Ensure careful handling of the carrying rails during disassembly.
•
Prevent screws from falling into the unit during disassembly and so causing damage
during operation.
Original roof screws
After removing the crane transport aids, the removed crane eyebolts or the mounting bolts of
the transport beam must be replaced by the original roof bolts from the accessories kit
supplied in order to ensure compliance with the degree of protection and proper grounding of
the cabinet. The tightening torque for the original roof bolts is 50 Nm.

3.3.3.3 Connection to the foundation
Connection to the foundation
Four holes for M12 screws are provided on each enclosure panel to secure the enclosure to
the ground. The fixing dimensions are specified in the dimension drawings.
Every cabinet panel must be attached to the ground using at least two opposing attachment
points (1 screw each in the front and rear part of the cabinet panel).
If this is not possible for reasons of accessibility, then the attachment points of the adjacent
cabinet panels must be correspondingly raised.
Generally, as many attachment points as possible should be used.
