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!
WARNING: The fan controllers contain high voltage capacitors that 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 if installed (L1, L2/N, and L3). Wait three (3) minutes for capacitors to discharge to safe voltage levels.
Failure to do so may result in personal injury or death. Note: Darkened display LEDs are not an indication of safe
voltage levels.
CAUTION: It is the sole responsibility of the installer to verify the operating voltage of the fan system prior to
installation! It is also mandatory that the installer verify that airfoils, motor hub assemblies, and fan controllers are
matched properly at the time of installation, especially if multiple fan systems will be installed.
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 Big Ass Fans-supplied variable frequency drive only. Not for use with other speed control
devices!
CAUTION: Shielded cable, if applicable, must be landed on the motor's ground terminal!
CAUTION: To avoid a short circuit, be very careful not to get metal chips in the controller!
CAUTION: The Big Ass Fans product warranty will not cover equipment damage or failure that is caused by improper
installation.
CAUTION: The following information is merely a guide for proper installation. The Big Ass Fans Company cannot
assume responsibility for the compliance or the non-compliance to any code, national, local, or otherwise for the proper
installation of these fan controllers, fans, or associated equipment. A hazard of personal injury and/or equipment
damage exists if codes are ignored during installation

Electrical installation overview

The electrical installation section is intended for a professional electrician. If you are unfamiliar or uncomfortable
with installing electrical components, do not attempt to install the fan without an electrician. Serious personal
injury or damage to the fan and other equipment could result. This guide is merely a recommendation of proper
installation. Adhering to national and local electric codes is your responsibility. It is the sole responsibility of the
installer to verify the operating voltage of the fan system prior to installation! It is also mandatory that the installer
verify that airfoils, motor assemblies, and fan controllers are matched properly at the time of installation, especially
if multiple fan systems will be installed.
The following sections outline how to prepare for the electrical installation, and include the required cables 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.

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.
