January 2022

Electronic commutation (EC) is the latest motor technology to be

used in direct drive fans. Also known in the industry as Brush Free

or Brushless DC, the EC motors utilize an electronic circuit board to

control the functionality of the motor. The motor operates off of

115V or 208/230V AC single phase power or 208/230V or 460 three

phase power, which is converted to DC power within the motor's

circuitry. The result is a highly efficient motor with an expanded

speed control range and a variety of speed control options from

which to choose.

REVIEW AMCA BULLETIN 410 PRIOR TO INSTALLATION

This manual has been prepared to guide the users of electronically commutated motors in the proper installation, operation

and maintenance procedures to ensure maximum equipment life with trouble-free operation. For safe installation, startup

and operational life of this equipment, it is important that all involved with the equipment be well versed in proper fan safety

practices and read this manual. It is the user's responsibility to make sure that all requirements of good safety practices and any

applicable safety codes are strictly adhered to. Because of the wide variety of equipment covered in this manual, the instructions

given here are general in nature. Additional product and engineering information is available at www.aerovent.com.

Refer to the safety section(s) in this manual prior to installing or servicing the fan. The most current version of this installation and

maintenance manual can be found on our website at www.aerovent.com/resources/im-manuals.
