5 Mounting
5.1 Selecting the Mounting Location
Requirements for the mounting location:
☐ The mounting location must be inaccessible to children.
☐ The inverter must be mounted on a solid building ground (e.g., concrete, wall) or at a drywall
in front of a stand or post.
☐ In a living area, please make sure that the surface is not made of plasterboard or similar. The
inverter makes noises when in use, which can be perceived as a nuisance in a living area.
☐ The mounting location must be suitable for the weight and dimensions of the inverter with
DC Disconnect (see Section 11 "Technical Data", page 82).
☐ The mounting location must be clear and have safe access 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.
☐ The mounting location must not be exposed to direct sources of water spray such as sprinklers
or gutters.
☐ Climatic conditions must be met (see Section 11 "Technical Data", page 82).
☐ The ambient temperature must be below 104°F (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 in areas where highly flammable materials are stored.
• Do not mount the inverter in a potentially explosive atmosphere.
The inverter can become hot during operation
Potential burn injuries when touching the enclosure.
• Install the inverter in such a way that it cannot be touched accidentally.
