Removing the protective cover on ATV212H drives
See Mounting methods, page 41 to determine the type of mounting appropriate for your application before
removing the protective cover from the drive.
When IP20 protection is adequate, remove the protective cover on top of the drive as shown below.
For UL Type 1 protection, leave the protective cover on top of the drive and install a conduit entry kit (mounting
outside the enclosure). See entry kit references in the catalog on www.se.com.
Derating curves
The curves illustrate the drive nominal current derating percentage (I/In%) as a function of the temperature,
switching frequency, and the different types of mounting (A, B and C).
For example, 80% derating of a 20 hp, 460 V ATV212 drive nominally rated for 30.5 amperes continuously: 30.5
x 0.8 = 24.4 (15 hp).
For intermediate temperatures, interpolate between two curves.
