Framed solar modules
Please note that the guarantee for the solar modules will expire if modifications are made to the module
frames (e.g. by drilling additional holes). For warranty reasons, the assembly instructions from the
respective solar module manufacturer must be strictly adhered to.
Lightning and surge protection
Please note that the lightning and surge protection of the PV system is to meet the current requirements
for

DIN / VDE 0185 part 1 to 4,

DIN / VDE 0100 part 712 and

VdS 2010
For more detailed information please refer to the local regulations and the aforementioned standards and
guidelines.
In general we recommend that you integrate the assembly system and the module frames into the local
potential equalisation and use surge protection devices.
Potential equalisation is always necessary if the solar modules used do not meet requirements for
protection class II and/or transformerless inverters are used.
The cross-section of the potential equalisation conductor must correspond to the main DC cables but must
be at least 6 mm² (copper).
If the building has a lightning protection system and the PV generator is not in the protection area of the
arresting device, then the module frame and assembly system must be integrated into the external
lightning protection and surge protection devices must also be installed.
The electroconductive connection must be implemented with at least 16 mm² (copper).
Cable routing
Even when you are installing the frame, certain points regarding cable routing and wiring should be kept in
mind.

To avoid surge voltage couplings from lightning strikes, the resulting conductor loop must be kept
as small as possible.

The cable routing must allow for any future slipping caused by snow and ice.

Water must not be allowed to collect around the wiring, continuous water drainage must be
provided.

The wires must be installed with maximum possible UV and weather protection.
