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.
☐ Do not mount the inverter on a pillar.
☐ A solid support surface must be available for mounting, e.g. concrete or masonry. When
mounted on drywall or similar materials, the inverter emits audible vibrations during operation
which could be perceived as annoying.
☐ The mounting location must be suitable for the weight and dimensions of the inverter (see
Section 10 "Technical Data", page 43).
☐ The mounting location should not be exposed to direct solar irradiation. Direct solar irradiation
can cause the inverter to overheat. As a result, the inverter reduces its power output.
☐ 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.
☐ To ensure optimum operation, the ambient temperature should be between -25°C and 40°C.
☐ Climatic conditions must be met (see Section 10 "Technical Data", page 43).
