scope:

These requirements cover refrigerating units intended for connection in accordance with the National Electrical Code, NFPA 70, to alternating-current (ac) circuits rated not greater than 600 volts.

This standard also covers component refrigeration systems (self-contained mechanical refrigeration systems), not already covered by a UL standard, that heat, cool or dehumidify as integral (not stand-alone) components of appliances.

Refrigerating units covered by these requirements employ sealed, hermetic-type motor compressors, and air- or water-cooled condensers.

These requirements do not cover equipment intended for comfort cooling.
