Electrical Installation
WARNING: To reduce the risk of electric shock, wiring should be performed by a qualified electrician! Incorrect assembly can
cause electric shock or damage the motor and the controller! Hazard of electrical shock!
WARNING: The installation of a Big Ass Fan must be in accordance with the requirements specified in this installation manual
and with any additional requirements set forth by the national electric code (NEC), ANSI/NFPA 70-2011, and all local codes.
Code compliance is ultimately YOUR responsibility! Failure to comply with these codes could result in personal injury or
property damage.
WARNING: The fan controllers contain high voltage capacitors which take time to discharge after removal of mains supply.
Before working on the fan controller, ensure isolation of mains supply from line inputs at the fan controller's disconnect (L1,
L2/N, L3). Wait 3 minutes for capacitors to discharge to safe voltage levels. Failure to do so may result in personal injury or
death. Darkened display LEDs are not an indication of safe voltage levels.
CAUTION: An incorrectly installed controller can result in component damage or reduction in the fan's life. Wiring or
application errors such as under-sizing the controller, incorrect or inadequate AC supply, or excessive ambient temperatures
may result in a malfunction of the fan system. Verify correct voltage, phase, and horsepower before beginning installation!
WARNING: Exercise caution and common sense when powering the fan. Do not connect the fan to a damaged or hazardous
power source. Do not attempt to resolve electrical malfunctions or failures on your own. Contact Big Ass Fans if you have any
questions regarding the electrical installation of this fan.
CAUTION: For use with manufacturer supplied variable frequency drive only. Not for use with other speed control devices!
CAUTION: Shielded cable, if applicable, must be landed on motor's ground terminal!
CAUTION: To avoid a short circuit, be very careful not to get any metal chips in the control!
CAUTION: The Big Ass Fans product warranty will not cover equipment damage or failure that is caused by improper
installation.

Electrical installation overview

The following sections of this chapter outline how to prepare for the electrical installation including what cables to select and how
to properly route the cabling through conduit; how to properly ground the fan system; how to properly wire the fan controller; how to
properly wire the fan motor; and proper startup procedures. The electrical installation section is written for a professional electrician. If
you are unfamiliar or uncomfortable with installing electrical components, do not attempt to install the fan alone. Serious personal injury
or damage to the fan and other equipment could result. This guide is a merely a recommendation for proper installation. Adhering to
national and local electrical codes is your responsibility!
The controller requires nonstandard installation practices to remain operational, namely the differentiation between solid state and
electromechanical systems. National and local codes do not make this differentiation, but the following guidelines do. These additional
requirements must be followed to ensure proper operation of the fan!

Controller storage

Store the controller within an ambient temperature range of -40°F to 185°F (-40°C to 85°C) and a relative humidity range of 0 to 95%,
non-condensing. Do not expose the controller to a corrosive atmosphere. If the controller has been in storage or disconnected from
power for more than one year, apply AC supply power to the controller for a period of two hours prior to operation in order to recondition
the internal DC bus capacitors.
