In the event of an existing lightning protection system

Modular use of our surge protection components

If a lightning protection system is already present on the

building, this must be at the highest point of the entire

system. All modules and cables of the photovoltaic

installation must be installed below the air terminations.

Separation distances of at least 0.5 m to 1 m must be

maintained (depending on risk analysis from IEC 62305-2).

The external Type I lightning protection (AC side) also

requires the installation of a Type I lightning arrester in the

electrical supply of the building. If no lightning protection

system is present, then Type II arresters (AC side) are

sufcient for use.
