Mounting instructions – MSP-FR-EW at roof PV mounting system
− Ensuring that suitable lifting gear is used for installation as appropriate.
− Ensuring that visibly damaged components are not used and are replaced.
− Ensuring each component is used as intended and indicated in the instruction manual, and that compo-
nents are not installed in a way as to perform other or additional tasks.
− Ensuring that only genuine Schweizer components are used when parts need to be replaced. Otherwise all
warranty claims will not be recognized.
− Ensuring that only Schweizer MSP-FR-EW, or other indicated Schweizer MSP components, are used for
the installation.
− Ensuring that the roof membrane is not damaged in any form by dropping, dragging or allowing the penet-
ration of components of the installation system.
− Ensuring that regular scheduled maintenance work is performed once every year, including inspecting of
screw connections, mechanical connections, positioning of protection sheets, cabling, electrical equaliza-
tion, and the condition of the roof membrane.
− Where necessary, it is the responsibility of the customer to adapt the existing lightening protection system
of the building in accordance with current technical rules and regulations.
− Prior to operating the PV system, the customer must ensure that the whole system, as well as each indivi-
dual panel, have the adequate electrical potential equalization. This should be tested by an appropriate
specialist.
− The Schweizer MSP-FR-EW system may be included in the design of, and connected to, the electrical po-
tential equalization system, by correctly tting a suitable earthing clamp or screw (not supplied by Schwei-
zer). The customer must ensure compliance with current rules and codes.
− The standards (or the equivalent applicable regional standards) for the design and installation of lightning
protection, grounding and equipotential bonding must be observed.
− DIN EN 62305 – lightning protection
− DIN VDE 0185 Parts 1-4 – lightning protection
− DIN VDE 0100 Part 410 – grounding
− DIN VDE 0105 – operation of electrical installations
− DIN VDE 0298 – electric cables
− The customer is responsible for ensuring that the roof where the system is installed is designed and const-
ructed so as to be able to adequately and safely withstand the system. This includes, amongst others, the
structural capabilities of the roof, the condition and compatibility of the roong membrane, the required
long-term bearing strength of the insulation material, and the adequate drainage of water away from the
roof surface. Schweizer cannot be held liable for damage to roofs where the roofs are not adequately desi-
gned or constructed to take the system installation.
− The customer is responsible for ensuring that the installation is in compliance with current national regulati-
ons and codes, including amongst others, maintaining the necessary edge distance to the roof, the provi-
sion of safety barriers, the restriction of access during operation, or precautions for expected dynamic
loads or specic conditions such as earthquakes and severe weather patterns.
− If the system is fastened to the building in any form, it is the responsibility of the customer to ensure the
adequate design and provision of that fastening.
− The rules and regulations of the Central Association of German Roofers (ZVDH) (or equivalent applicable
regional standards) pertaining to working on roofs must be observed.
− DIN 18338 roong work
− DIN 18451 scaffolding work
− Guideline VDS 2023 on damage prevention – electrical installations in buildings or structures with mainly
ammable materials, and DIN 4102 – re behavior of building materials and building components (or the
equivalent applicable regional standards) must be observed.
