
Prevent fiber particles, scraps of paper, shredded wood sawdust, metal particles, etc. from adhering
to the heat sink.

Install the AC motor drive in a metal cabinet. When installing one drive below another one, use a
metal separator between the AC motor drives to prevent mutual heating and to prevent the risk of
accidental fire.

Install the AC motor drive in Pollution Degree 2 environments only: normally only non-conductive
pollution occurs and temporary conductivity caused by condensation is expected.

Mount the drive in an IP66 or NEMA 4X cabinet in order to maintain the Pollution Degree 2 or in a
pollution-controlled environment.
