3.2.2 Mechanical Mounting
1. Drill holes in accordance with the measurements
given.
2. Provide screws suitable for the surface on which
the compressor drive should be mounted.
3. Retighten all four screws.
The frequency converter IP20 allows side-by-side instal-
lation. Because of the need for cooling, there must be a
minimum of 7.9 in (200 mm) free air passage above and
below the frequency converter.
The back wall must always be solid. All frequency
converters are equipped with a back metal plate to
guarantee proper heat exchanger ventilation. Never
remove this metal sheet.
