5.1.4 Mechanical Mounting

All enclosure types allow side-by-side installation except

when a IP21/IP4X/TYPE 1 Enclosure Kit is used (see

chapter 3.1 Options and Accessories).

Side-by-side mounting

IP20 A and B enclosures can be arranged side-by-side with

no clearance required between them, but the mounting

order is important. Illustration 5.1 shows how to mount the

frames correctly.

Illustration 5.1 Correct Side-by-side Mounting

If the IP 21 Enclosure kit is used on enclosure type A2 or

A3, there must be a clearance between the frequency

converters of min. 50 mm.

For optimal cooling conditions, allow a free-air passage

above and below the frequency converter. See Table 5.4.
