Installation Manual

Recommended clearances:
To guarantee optimal operation and adequate heat dissipation for the inverter, the following
requirements for clearances should be observed. This will prevent the inverter power output from
being reduced due to excessive temperatures. However, smaller clearances are permitted without
causing any risk.
Prescribed clearances in accordance with the
National Electrical Code
®
Under certain conditions, the National Electrical Code
®
specifies greater clearances.
• Ensure that the prescribed clearances in accordance with the National Electrical Code
®
,
paragraph 110.26 and Canadian Electrical Code
®
CSA C22.1 are adhered to.
☐ Observe the recommended clearances to walls as well as to other inverters or objects.
☐ If multiple inverters are mounted in areas with high ambient temperatures, increase the
clearances between the inverters and ensure an adequate fresh-air supply, if possible.
Figure 4 : Recommended clearances
Permitted and prohibited mounting positions:
☐ The inverter must only be mounted in one of the permitted positions. This will ensure that no
moisture can penetrate the inverter.
☐ The inverter should be mounted in such way that display messages and LED signals can be
read without difficulty.
