6.1 Application Examples
6.1.1 Compressor
The SmartStart guides the user through the set-up of a refrigeration compressor asking for input data about the compressor
and the refrigeration system on which the frequency converter will be running. All terminology and units used within the
SmartStart are common refrigeration type and set up is thus completed in 10-15 easy steps using just 2 keys of the LCP.
