Site basis
Power Electronics recommends making a concrete foundation slab to support the charger. The support
surface for the equipment must be perfectly level. The client is responsible for the correct
dimensioning and construction of the foundation in accordance with current regulations. The
foundation must meet the following characteristics:
• It is recommended that a layer of cleaning concrete be installed between the ground and the
foundation.
• The sizing should be appropriate for the weight of the equipment and the characteristics of the soil
• It must be thick enough to support the equipment.
• It must have trenches wide enough to ensure proper wiring passage (the suggested cable access
size is shown below).
The client is responsible for building a solid concrete base perfectly leveled and elevated with
respect to the user's floor height.
In case of specification of variable actions such as snow, wind or earthquake, the slab must comply
with the following requirements, not being excluding those indicated by the specific regulations
of the country of installation:
• Ability to withstand compression forces of 25 N/mm
2
.
• Steel reinforcement capable of withstanding tensile forces of 500 N/mm
2
.
• Taking into account severe wind conditions (60 m/s), the reinforcement should be dimensioned as
follows:
The longitudinal side of the reinforcement must be able to withstand forces of up to 80 kN.
The transverse side of the reinforcement must be able to withstand forces of up to 10 kN.
Note that the thickness of the slab must be determined from the results of the geotechnical
study.
