NOTICE
Document the location of all the cables in the ground between the Power
Cabinet and the Charge control set. The routing of the cables can be
found easily in the future, for example, to prevent damage by excavation
work.
3.9. Lightning protection
One electrode (ground rod) of maximum 10
Ω must be placed in to the earth near the pole
foundation. It is recommended to place two electrodes near the pole. In some cases also
additional grounding is required at the Power Cabinet side. This is dependent on the local
regulations and should be determined by the contractor.
If the grid is TT based, consult the grid owner. It is possible that an extra 0,9 Ω electrode is
required. This requirement must be determined by the contractor.
Consult a local specialist for the options of lightning protection. The Charge control set has to
be within the protection angle of the lightning distraction. This requirement must be determined
by the owner and a local specialist (according to NFPA 780).
The implementation of the lightning protection depends on the local laws, safety and electrical
regulations. This requirement must be determined by the contractor and owner of the site /
HVC 450 kW E-Bus Charger.
