• If the inverter is mounted outdoors, the clearance below the inverter must amount to 3 ft. (900 mm).
This prevents the ingress of waterspray into the inverter.
• Observe recommended clearances to the walls as well as to other inverters or objects. Thus, you
will prevent the inverter's power output from being reduced due to excessive temperatures.
• If multiple inverters are mounted in areas with high ambient temperatures, increase the
clearances between the inverters and ensure sufficient fresh-air supply. Thus, you will prevent
the inverter's power output from being reduced due to excessive temperatures.
• Do not mount inverters on top of one another. This prevents the upper inverter from drawing in
the heated air from the lower inverter.
Observe permitted mounting position:

• Mount the inverter in a permitted mounting position at eye level. This ensures that there can be
no ingress of moisture into the inverter and you can read out display messages and LED signals
without any problems.
