3.3 Push-through mounting (frame sizes B ... D)
The frame sizes B to D are designed to be compatible with "push-through" applications,
allowing you to mount the heatsink of the inverter through the back of the cabinet panel.
When the inverter is mounted as the push-through variant, no higher IP rating is achieved.
Make sure that the required IP rating for the enclosure is maintained.
An additional mounting method is also available for different frame sizes. For more details,
refer to the following section:
