Constructing earthing electrode and earthing
Construct an earthing electrode for the MVCS according to the local regulations.Connect the earthing electrode to the general earthing bar
of the MVCS using the right cross section. For more information, see drawing “MVCS Grounding Layout”.
Filling the pit and finalizing the surroundings
1. If required for local frost conditions, add insulation around the column foundation.
2. To minimize the growth of grass, use geotextile below the foundation and below the service platform around the MVCS. Put the geotex-
tile 20 cm (8 in) below and about 100 cm (40 in) around the foundation.
3. The MVCS is a not walking station, it is designed to be operated from the outside. Provide a permanent or portable platform for comfort-
able operation of the MVCS switching devices as the foundation can be higher than the surrounding ground. For platform design and
construction, follow the local rules and standards.
4. Do not plant trees near the MVCS. If bushes are planted, make sure that the planting compost base is at least one meter (40 in) away
from the station housing and that the fully-grown bushes do not prevent maintenance access to the MVCS. Make sure that anything
planted near the inverter does not discharge dust or seeds that can affect the cooling air flow
