Do not install heat sensitive components right above the inverter.
ATTENTION!
When arranging two or more inverters vertically, respect the minimum

on page 216. Remove the drive mounting brackets for flange mounting. The protection degree
of the inverter outside the panel is IP55 for flange mounting. It is necessary to provide proper
seal for the opening where the inverter is installed to ensure the protection degree of the panel.
Example: sealing with silicone.
