Environmental and enclosure protection Verify that the installation site meets the requirements for the environment in which it is to be used.

To prevent damage, storage and transport prior to installation must be carried out in accordance with the requirements for storage and transport in the environmental requirements.

See ‘Environmental conditions’ on page 232. Depending on the degree of contamination on site, check that the enclosure protection class is appropriate:

– IP21/ UL 1 Enclosure. The site must be free of floating dust, corrosive gases or liquids, and electrically conductive contaminants such as condensation, charcoal dust, metal particles, etc.

– IP54/ UL 12 enclosure. This enclosure provides protection against airborne dust and light splashes and droplets from all directions.

Make sure that the installation location fulfils the following conditions:

– The frequency converter must be mounted vertically on a smooth, solid surface and comply with the environmental requirements mentioned above.

– The minimum space requirement for the frequency converter is the external dimensions (see ‘External dimensions’ on page 231) plus the ventilation space around the frequency converter.

– The distance between motor and frequency inverter is limited by the maximum motor cable length.

– The installation location must be able to support the weight and noise output of the frequency converter. See ‘Weight’ on page 232.
