26 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, 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 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 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.
CAUTION: If it was determined that a motor frequency less than 60 Hz is optimal for maximum performance of your particular
fan model, under no circumstances should the factory programmed maximum frequency command limits be changed.
Damage to the fan assembly or loss of warranty coverage can result.
ATTENTION: If installing the fan in the United States, the fan must be installed per the following National Fire Protection
Association (NFPA) guidelines:
• The fan must be centered approximately between four adjacent sprinklers.
• The vertical distance from the fan to the sprinkler deflector must be at least 3 ft (91.4 cm).
• The fan must be interlocked to shut down immediately upon receiving a waterflow signal from the alarm system .
