Aggressive environments
As all other electronic equipment, a frequency con-
verter contains a number of mechanical and electronic
components, which to a varying extent are vulnerable
to environmental impact.
Consequently, the frequency converter is
not to be installed in environments, where
liquids, particles or gases are in the air
that would impact and damage the elec-
tronics. Unless the necessary measures
are taken to protect the frequency con-
verter, there is a risk of stoppages, which
reduce the service life of the frequency
converter.
Liquids can be carried through the air and condense
in the frequency converter. In addition, liquids may fa-
cilitate galvanic corrosion of components and metal
parts. Steam, oil and brine may cause corrosion of
components and metal parts. In these areas, it is rec-
ommended to fit units in cabinets. As a minimum,
cabinets should be enclosure IP 54.
Particles in the air, such as dust particles, may lead to
mechanical, electrical and thermal faults on the fre-
quency converter. Typical indicators that there are too
many particles in the air are dust particles around the
frequency converter fan. In very dusty areas, cabinet
