Preconditions
• The panel is placed on its assigned place of installation
•
Access to the connection compartment is established
•
Deep bottom pan available from the supplementary equipment for the switchgear
Procedure
Take the pre-assembled bottom pan from the supplementary equipment of the delivery.
For further installation, the pre-assembled bottom pan must be disassembled, so that the parts can be
installed individually in the base frame of the connection compartment. To do this, unscrew the
connecting elements (3), (4) and (5) completely, and store the individual components and the
connecting elements for later use.
If there is a substation earth in the panel, remove and dispose of the cover plate (6) for elongated
cutout. If there is no substation earth in the panel, keep the cover plate (6) for elongated cutout in the
deep bottom pan.
