5.1.4 Mechanical Mounting
All A, B and C enclosures allow side-by-side installation.
Exception: If a IP21 kit is used, there has to be a clearance
between the enclosures. For enclosures A2, A3, B3, B4 and
C3 the minimum clearance is 2 in [50 mm], for C4 it is 3 in
[75 mm].
For optimal cooling conditions, allow a free air passage
above and below the Adjustable frequency drive. See
Table 5.6

Table 5.7 When mounting enclosure sizes A5, B1, B2, B3, B4, C1, C2, C3 and C4 on a non-solid back wall,
the adjustable frequency drive must be provided with a backplate A due to insufficient cooling air over the heatsink.
