etal separator between the AC motor drives to prevent mutual heating and to prevent the risk of
accidental fire.
Install the AC motor drive in a Pollution Degree 2 environment with clean and circulating air. A clea
n
and c
irculating 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)
env
ironment, 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
different.
