Lifting the door
1. Open the handles.
2. Detach the upper part of the door.
3. Lift the door upwards.
Miscellaneous
Cable duct in the floor below the cabinet
You can construct cable ducts below the cabinet. The duct width must not exceed 450 mm
(18 in). The cabinet weight lies on the 100 mm (4 in) wide sections in front, middle and
back which the floor must carry.
Prevent the cooling air flow from the cable duct to the cabinet by bottom plates. To ensure
the degree of protection for the cabinet use the original bottom plates delivered with the
converter. With user-defined cable entries, take care of the degree of protection, fire
protection and EMC compliance.
Electric welding
It is not recommended to fasten the cabinet by welding. If you must do it for some reason:
•
Weld only the flat bar under the cabinet, never the cabinet frame itself.
•
Clamp the welding electrode onto the flat bar about to be welded or to the next flat bar
of the cabinet (within 0.5 meters of the welding point).
WARNING!
If the welding return wire is connected improperly, the welding circuit
may damage electronic circuits in the cabinet. The thickness of the zinc coating of
the cabinet frame is 100 … 200 micrometers; on the flat bars the coating is
approximately 20 micrometers. Ensure that the welding fumes are not inhaled.
