4.2 Selecting the Mounting Location
Observe the following conditions for mounting:
• The mounting method and location must be suitable for the weight and size of the inverter.
• Mount on a solid surface.
• The mounting location must be clear and safely accessible at all times without the use of
additional aids such as scaffolding or lifting platforms. Non-fulfillment of these criteria may
restrict service friendliness.
• Mount vertically or tilted backwards by max. 45°.
• Never mount the device with a forward tilt.
• Never mount the device with a sideways tilt.
• Do not mount in a horizontal position.
• The connection area must point downwards.
• Mount at eye level so that operation states can be read.
• The ambient temperature should be below 40°C to ensure optimum operation.
• Do not expose the inverter to direct solar irradiation as this can cause over-heating and hence
power reduction.
• To avoid audible vibrations in living areas, do not mount the unit on plasterboard walls or
similar. The inverter can make noises when in use which may be perceived as a nuisance in
living areas.
