Specifications and Features for E7C Drive Configured The E7C Configured package provides an E7 drive in a NEMA 1 or NEMA 12 enclosure, with space for several commonly used options, such as reactors, RFI filters, circuit breakers, etc. The E7 Drive is a variable torque AC drive, designed specifically for HVAC applications in building automation. A new benchmark for size, cost, performance, benefits, and quality, the E7 includes numerous builtin features such as network communications, H/O/A, PI control, and energysavings functions. The E7 has embedded communications for the popular building automation protocols, Johnson Controls Metasys N2 and Siemens APOGEE FLN, as well as Modbus. An optional LonWorks interface card is also available. E7 Performance Features ·
