equipment in a cabinet with fresh air ventilation, keeping
aggressive gases away from the frequency converter.
Before installing the frequency converter, check the
ambient air for liquids, particles, and gases. These checks
are done by observing existing installations in this
environment. Typical indicators of harmful airborne liquids
are water or oil on metal parts, or corrosion of metal parts.
Excessive dust particle levels are often found on instal-
lation cabinets and existing electrical installations. One
indicator of aggressive airborne gases is blackening of
copper rails and cable ends on existing installations.
