There are several guidelines that need to be observed when installing safety arches:
1. The safety arches protect the front side of the charging station, therefore the arch must
be aligned with the rear side of the station (underground anchoring structure),
2. The safety arches on the left and right side of the charging station must be placed at a
distance at least 15 cm from the station,
3. The height of the installed arches is 70 cm above the final level of the foundation.
If the charging station is located on the pavement, the two front ends of the safety arches on
one side must be installed at the edge of the roadside kerb and the charging station must be
placed away from the roadside kerb so that its rear end is aligned with the two rear ends of the
safety arches.
The station can be protected by one or two safety arches (see below) that can be placed at
both sides (2 arches) or at the front (1 arch) of the station.
