3-1 Mounting Clearance
Prevent fiber particles, scraps of pap
er, 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 conductivi
ty caused by condensation is expected.
To ensure the environment to install drives is in Pollution Degree 2, the drives should be installed in
an IP54 cabinet or in a pollution-controlled environment. Pollution Degree 2 (IEC / EN 60664-1) is
that temporary electric conduction may occur when dew forms, electrical equipment in control panel
and thermostatic chamber just causes non-conductive pollution.
The following figures are for instruction, and the actual drives shall prevail.

NOTE: The minimum mounting clearances A–C in the table above apply to AC motor drives installation.
Failing to follow the minimum mounting clearances may cause the fan to malfunction and cause heat
dissipation problems.
