Installation

For electrical installation, the applicable standards for surge protection must be observed. We
recommend the use of a type 1+2 surge arrester for charging stations with public mains connection
in the pre-counter area. Charging stations which are supplied from distribution boards that are
already protected must be equipped with at least one type 2 surge arrester. In addition, for DC
charging systems with cable runs of more than 10 metres between the operating and power units,
additional surge protection should be provided for both the AC and DC lines.
If the charging system is installed in a TT network, an appropriate residual current protection device
must be provided in the pre-installation.
The necessary torques of the main switch or the protective conductor and neutral conductor
terminals must be observed. The torques can be taken from the corresponding data sheets.
If type 1 surge protection is installed, an additional connection to the equipotential bonding or the
local earthing system is required. A separate equipotential bonding rail is provided in the charging
station for this purpose.
Any change to an adjustable current value of the charging point or charging points may only be made
by a qualified electrician.
