Preparing installation
5.1
Preliminary clarifications
In order to load the transport units in a suitable installation order, the regional Siemens representative requires
the following information from you several weeks before delivering the switchgear:
•
Sketch of the installation room including the locations and numbers of the individual panels and the
storage location for the accessories
•
Sketch of the access route from the public road to the switchgear building and information concerning
the condition thereof (meadows, arable soil, sand, gravel, etc.)
•
Sketch of the transport route inside the switchgear building with the locations and dimensions of doors
and other narrow points, as well as the floor number of the installation room
•
Information about available lifting equipment, e.g. mobile crane, fork-lift truck, lifting truck, hydraulic
jack, roller pads. If no lifting equipment is available, please notify this explicitly
5.2
Switchgear room
Observe the following points when preparing the switchgear room:
•
Base frame and switchgear dimensions
•
Transport ways to the switchgear room
•
Distribution and intermediate storage spaces
•
Size of the room and the doors
•
Construction and load-bearing capacity of the floor
•
Illumination, heating, power and water supply
•
Dimensions of installation scaffoldings and foundation rails
•
Installation of high-voltage cables
•
Earthing system
•
Cleanliness: Switchgear room free of dirt and dust
5.3
Foundation
Please observe the following items when preparing the foundation:
•
A suitable foundation can be a false floor, a double floor or a reinforced-concrete foundation. The
reinforced-concrete floor must be equipped with foundation rails for supporting the panels.
•
As for design and construction of the foundation, the relevant standards DIN 43661
"Fundamentschienen in Innenanlagen der Elektrotechnik" (Foundation rails in electrical indoor
installations) and DIN 18202 "Maßtoleranzen im Hochbau" (Blatt 3) (Measuring tolerances in structural
engineering (Sheet 3)) apply.
•
The dimensions of the floor opening and the fixing points of the switchgear frame are given in the
associated dimension drawings. These dimension drawings are made available by the regional
Siemens representative.
•
If the foundation has to be resistant to earthquakes, additional points must be considered. Please seek
the corresponding information in time. Your regional Siemens representative will be pleased to give
you advice.
•
Determine level differences between the installation surfaces of the panels using a measuring sheet,
and compensate these level differences with shims (0.5 mm to 1.0 mm).
•
The foundation area in front of the high-voltage doors of the panels, on which the withdrawable parts
or switching-device trucks are approached, inserted and removed, must be at the same level as the
standing surface of the panels.
The panel version with/without rear duct has no influence on the fastening to the foundation.
The following illustrations show general measuring sheets. For further information, see information drawings
