5 Mounting
5.1 Selecting the Mounting Location
Requirements for the mounting location:
☐ The mounting location must be inaccessible to children.
☐ A solid foundation must be available for mounting, e.g. concrete or masonry. When mounted
on plasterboard or similar materials in a living area, the inverter will develop audible vibrations
during operation, which could be considered disturbing.
☐ The mounting location must be suitable for the weight and dimensions of the inverter
(see Section 13 "Technical Data", page 77).
☐ The mounting location must be easily and safely accessible at all times without the use of
additional aids being necessary, e.g., scaffolding or lifting platforms. Non-fulfillment of these
criteria may restrict servicing.
☐ The mounting location must not be exposed to direct solar irradiation. Direct solar irradiation
can overheat the inverter. As a result, the inverter reduces its power output.
☐ Climatic conditions must be met (see Section 13 "Technical Data", page 77).
☐ The ambient temperature must be below 40°C to ensure the optimal operation of the inverter.
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the inverter on flammable construction materials.
• Do not mount the inverter in areas where highly flammable materials are stored.
• Do not mount the inverter in a potentially explosive atmosphere.
