Read and understand these instructions before attempting final assembly works.
12.1 Cleaning the switchgear
Foreign objects
Possible malfunctioning and switchgear damage caused by foreign objects.
Check whether the non-fastened compartments of the switchgear still
contain foreign objects, and remove them if required:
• Switching-device compartment
• Low-voltage compartment
If it cannot be determined without any doubt that the bolted busbar
compartment, pressure relief duct and connection compartment do not
contain any foreign objects, make these compartments accessible and
check as well:
• Busbar compartment
• Pressure relief duct
• Connection compartment
Greased parts and surfaces
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.
Cleaning
Use vacuum cleaners and dry, lint-free cloths.
