Insertion mounting
Observe the manufacturer‘s instructions for the mount-
ing system. Use the earthing holes for the potential
equalisation.
Although edge-to-edge mounting is possible (see also
Ch. 5
.4.1: „Intervals between PV modules with stand-
ard
frames“), we recommend mounting at intervals.
7.5
Load levels
A load can be a pressure load as well as a suction
load. Loads from snow and wind need to be taken into
account at the installation site.
The maximum permissible load is 2400Pa (for wind
and snow) when mounting the modules by using
crews, clamps or insertions systems
If there is a risk of sliding snow, an appropriate meas-
ure has to be taken so that PV module frames on lower
edge of PV modules will not be damaged (e.g. by
using snow hook).
The PV modules have passed a snow load test in
accordance with IEC61215.
