4.2.3. Mechanical mounting
All IP20 enclosure sizes as well as IP21/ IP55 enclosure sizes except A2 and A3 allow side-by-side installation.
If the IP 21 Enclosure kit (130B1122 or 130B1123) is used on enclosure A2 or A3, there must be a clearance between the drives of min. 50 mm.
For optimal cooling conditions allow a free air passage above and below the frequency converter. See table below.
