6.1.2 Mechanical Mounting
All Frame Sizes allow side-by-side installation except when a
IP21/IP4X/ TYPE 1 Enclosure Kit
is used (see the
Options and Accessories
section of the
Design Guide).
If the IP 21 Enclosure kit is used on frame size A1, A2 or A3, there must be a clearance between the drives of a minimum of 2 in [50 mm].
For optimal cooling conditions, allow a free air passage above and below the adjustable frequency drive. See table below.
