Installation of the module
Ensuring safe installation
Secure yourself and other persons against falls; do
not carry out installation work in strong winds and
prevent objects from falling if possible. Carefully
secure the working area to avoid danger or injury
to persons.
Always comply with the permissible maximum
mechanical load in accordance with DIN EN
1991-1-3/DIN EN 1991-1-4
Ensure that the maximum mechanical load is not
exceeded and take into account any location-de
-
pendent loads such as wind or snow. Remember
that the module could bend under high load.
When using fastening elements, cable ties or com
-
parable connecting materials between the back
of the module and the cross profiles, ensure that
the module is not damaged by pointed or uneven
structures.
Ensuring that the modules are properly
earthed
In accordance with the provisions of SF Solar Fa
-
brik GmbH
& Co. KG, it is not necessary to earth the module
frames and rack for trouble-free operation. To avoid
the risk of electric shock (e.g. from static charges)
as far as possible, SF Solar Fabrik GmbH
& Co. KG recommends having the installer carry
out professional earthing.
If an external lightning protection device is availab
-
le, a technical specialist must integrate the PV sys
-
tem in the lightning protection concept while obser
-
ving country-specific standards and regulations.
A qualified electrician must check the earthing
connections between the modules. A qualified
electrician must also connect the main earthing.
An earthing method approved by Underwriters La
-
boratories (UL) is mandatory in the USA and Ca
-
nada.
For proper earthing, ensure optimum electrical
conductivity. For this purpose, earthing holes are
provided on the back of the module frame. These
Earthing holes are
marked with a
earthing symbol:
▪ Positions for M/P series
▪ Additional options for Mono S2
Attach the earthing clamp to one of the specially marked
earthing holes on the rear side of the module frame.
