5.1 Requirements for Mounting
Requirements for the mounting location:
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the inverter in areas containing highly flammable materials or gases.
• Do not mount the inverter in a potentially explosive atmosphere.
☐ The inverter must be mounted on a solid support surface (e.g. concrete, brickwork, suitable
constructions). When mounted on drywall or similar materials, the inverter emits audible
vibrations during operation which could be perceived as annoying.
☐ The inverter can be mounted in a position that is directly exposed to solar irradiation. Direct
solar irradiation can cause the inverter to overheat. As a result, the inverter reduces its power
output.
☐ The DC load-break switch of the inverter must always be freely accessible.
☐ The mounting location must be suitable for the weight and dimensions of the inverter (see
Section10 "Technical Data", page60).
☐ To ensure optimum operation, the ambient temperature should be between -25°C (-13°F) and
+45°C (113°F).
☐ Climatic conditions must be met (see Section10 "Technical Data", page60).
☐ 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.
