Assembling the switchgear

In the instructions given in the following sections it is assumed that a new switchgear is being
installed which has not yet been connected to the mains, and that it is therefore not live.
ATTENTION!
Dirt in the switchgear can cause malfunctions during operation.
Avoid any work that could pollute the switchgear (e.g. sawing, filing, etc.).

Bolting panels together

NOTE!
In order to establish a panel joint (busbar panel joint) more easily, pre-assembled low-voltage
compartments can be removed for panel connection. Low-voltage compartments on end
panels may remain mounted.
Remove low-voltage compartments pre-assembled at the factory.

The first panel is on its mounting position and the others are placed at a small distance.
Align the first panel laterally.

If necessary, lay shim plates under the panels to align them in vertical and horizontal

position.
Carefully approach the next panel to the one that has already been aligned.

Align the approached panel by means of the alignment brackets provided at the vessel, and

make sure that it is vertical and at the necessary height using shim plates if required.
ATTENTION!
To take individual panels out of the switchgear assembly, please observe the following for
panels that had been provided for free-standing arrangement, but are now installed in wall-
standing arrangement:
Do not mount the sealing strip.
