5 Mounting
• 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 minimum clearances to the walls as well as to other inverters or objects. This ensures
adequate heat dissipation and sufficient space.
• 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.
Prescribed clearances
Under certain conditions, the National Electrical Code
that you adhere to the prescribed clearances according to the National Electrical Code
Paragraph 110.26.
Installations in Canada must be carried out in accordance with the applicable Canadian
standards.
Observe permitted mounting position:
Figure 10: Permitted and prohibited mounting positions
• 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.
