Chapter 3 Installation
Minimum Mounting Clearance and Installation
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, where normally only non-
conductive pollution occurs and temporary conductivity caused by condensation is expected.
Mount the drive in an IP54 cabinet in order to maintain the Pollution Degree 2 or in a pollution-
controlled environment.
