5 MountingSMA Solar Technology AG Installation Manual SBxx-1SP-US-41-IA-xx-12 23 5 Mounting 5.1 Requirements for Mounting Requirements for mounting location: WARNING Danger to life due to fire or explosion Despite careful construction, electrical devices can cause fires. This can result in death or serious injury. • Do not mount the product in areas containing highly flammable materials or gases. • Do not mount the product in potentially explosive atmospheres. ☐ A solid support surface must be available (e.g. concrete or masonry, free-standing constructions). When mounted on drywall or similar materials, the inverter emits audible vibrations during operation which could be perceived as annoying. ☐ The installation site can be exposed to direct solar irradiation. There is, however, the possibility that the product reduces its power output to avoid overheating due to high temperatures. ☐ When using the SMA Cellular LTE Modem Kit, the installation site should not be located in the basement. The data transmission during basement installation can be restricted due to an insufficient connection quality. ☐ The mounting location should be freely and safely accessible at all times without the need for any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these criteria may restrict servicing. ☐ The DC load-break switch of the product must always be freely accessible. ☐ All ambient conditions must be met (see Section 10, page 65). Permitted and prohibited mounting positions: ☐ The product may only be mounted in a permitted position. This will ensure that no moisture can penetrate the product. ☐ The product should be mounted in such way that display messages and LED signals can be read without difficulty. 15° Figure 3 : Permitted and prohibited mounting positions ☐ Do not mount multiple inverters directly above one another.
