 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
fire accident.
 Install the AC motor drive in a Pollution Degree 2 environment with clean and circulating air. A clean
and circulating environment means air without polluting substances and dust.
 Mount the drive in an IP54 cabinet in order to maintain the Pollution Degree 2 or in a pollution-
controlled environment. When installing the AC motor drive in a Pollution Degree 2 (IEC/EN 60664-
1) environment, only nonconductive pollution occurs for the electrical equipment in the cabinet and
thermostatic chamber and temporary conductivity caused by condensation is expected.
The appearances shown in the following figures are for reference only. The actual motor drives may look
