7.5 Fastening the panels to the foundation
Fastening to the foundation
When the panel is bolted or welded to the floor, this can cause gaps and openings
that do not meet the degree of protection of the switchgear.
After bolting or welding the panel to the floor, verify the gap dimensions
according to the degree of protection.
If necessary, re-align the parts moved for bolting the panel to the floor, in
order to provide the gap dimensions according to the degree of protection.
Compensate gaps up to 2.5 mm with sealing compound,
e.g. SIKAFLEX 221-GR 310 ML.
In case of gaps > 2.5 mm, inform the regional Siemens representative.
Cleaning
Possible malfunctioning and damage to the panels caused by pollution.
Clean polluted areas. To do this, use a vacuum cleaner and a lint-free cloth.
If necessary, moisten the cloth, use a mild household cleaner, and dry
properly at the end.
Some parts and surfaces of the switchgear are greased for functioning. Do
not remove the grease there; do not clean the parts and surfaces.
If greased areas are dirty, clean the dirty area and grease again according
to the maintenance instructions.
The switchgear panels can be fastened to the foundation as follows:
•
Welded floor fixing or bolted floor fixing on concrete floor with C- or U-profile foundation rails
•
Bolted floor fixing on double floor
• Bolted floor fixing on concrete floor with U-profile foundation rails and additional earthquake stabilization
