The document discusses several applications for SED2 variable frequency drives including temperature control, pressure control, belt monitoring, and duct pressure control. It provides examples of input/output configurations and solutions using the built-in functions of the SED2 drive like PID control, pump cascading logic, and static pressure control. It also reviews mounting and installation considerations for selecting the proper enclosure type and installing line and load reactors.
