About Big Ass Fans

Our provocative moniker originated with the massive overhead fans we perfected to bring comfort and energy savings to large industrial buildings. Today, though, Big Ass Solutions is much more than industrial—and much more than Big Ass Fans or Big Ass Light. Big Ass means quality, form, and function to solve problems in the built environment. It means having a herd of engineers on sta and the world’s only R&D facility dedicated to testing air movement on a grand scale. It means speaking to our customers directly to understand and solve their problems— if they need air movement, we do it bigger and better. If they need light, we make incredibly bright, long-lasting LEDs. But mostly it means an insatiable drive to improve, engineer, design, test, re-engineer, re-design, and re-test until we get it just right. That’s why there’s No Equal

PIVOT ANGLE

Pivoting the fan decreases the amount of clearance the fan has from the ceiling and the ﬂoor. Before installing the fan, verify that it will have adequate clearance using the diagram below.

Observe the following safety measures when pivoting the fan:

• To pivot the fan at its maximum angle, a minimum extension tube length of 3 ft is recommended.

• The lowest moving part of the fan must be at least 10 ft (3.05 m) above the ﬂoor.

• After the fan is pivoted, there should be adequate clearance between the airfoils and any obstructions.

• Take special precaution to ensure that fan blades will be clear of safety cable and motor cable.

MOUNTING STRUCTURE: I-BEAM

ATTENTION

Big Ass Fans can only be hung from an I-beam or bar joists. See the following page for bar joist mounting instructions. Consult a structural engineer for installation methods not covered in this manual.

WARNING: The following instructions assume that the customer’s roof structure from which the fan will be hung is of sound construction, undamaged, and capable of supporting loads of up to 645 lbs (293 kg). It is the sole responsibility of the customer to verify that the roof structure is adequate for fan installation. Big Ass Fans recommends consulting a structural engineer prior to fan installation.

CAUTION: It is not recommended to mount a Big Ass Fan from a fabricated I-beam.

CAUTION: Install the spacers only if the thickness of the I-beam ﬂange exceeds 3/8” (1 cm). The mounting holes on the spacer are closer to one side than the other. Make sure this side is facing the I-beam.

1. Attach upper yoke (to I-beam)

Measure the ﬂange width of the I-beam from which the fan will be hung. Consult the tables and diagram below to determine what size upper yoke is included with your fan package. Select the upper yoke mounting holes that match the ﬂange width of the I-beam.

Secure the upper yoke to the I-beam with the Beam Clip Hardware as shown. Tighten the bolts to 40 ft·lb (54.2 N·m) using a torque wrench and 3/4” socket.

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.

Page 30

Power requirements for fan controllers

The power requirements for Big Ass Fans controllers are shown in the speciﬁcation table in the introduction. If multiple controls are connected to one feeder circuit, the circuit required is the sum of the feeder circuit requirements listed on the chart. For example, if two 240 V, 3 Φ controllers are connected to a single feeder circuit, that circuit needs to be rated for 20 amps. This type of installation will also require that each fan control be installed downstream from a dedicated over-current protection device

Mounting the wall controller

Mount the controller to a wall using a #8–#10 screw. Adhere to the following guidelines when selecting the controller location:

• Install the controller on a ﬂat surface that is readily accessible, free from vibration, and where there is adequate distance from foreign objects or moving equipment.

• Do not mount any controller adjacent to or above a heat source or heat-producing equipment.

• The ambient temperature must be between 14º F (-10º C) and 122º F (50º C).

• Do not expose the controller to a corrosive atmosphere or direct sunlight.

• When mounting the controller, keep in mind that the fan should be visible from the controller.

• A minimum distance of 6” (15.2 cm) should be maintained between fan controllers.

Note: Multiple fan controllers are available as a special order only. Please contact Customer Service for more information.

• Frequent power interruptions

• Phase-to-ground voltage in excess of 125% nominal phase-to-phase voltage

• Distribution system exceeds established kVA limit for your speciﬁc model (contact Big Ass Fans for more information).

• Power factor correction capacitors

• Intermittent noise spikes (lightning)

Page 31

Conduit and piping guidelines

CAUTION: The presence of foreign signals on a drive’s output wiring greatly reduces the controller’s ability to control current and speed regulation of the fan. Any wiring practice that would allow this kind of “cross-talk” must be avoided. Failure to do so may result in nuisance tripping and/or premature equipment failure. Sources of foreign signals that could induce such signals include another VFD’s output circuit, long “across-the-line” motor circuits, and lighting circuits.

CAUTION: Recommendations for fan controller output/motor lead routing deem some conventional wiring practices “unacceptable.” National and/or local code does not dierentiate between solid-state and electromechanical systems; however, due to the nature of the Big Ass Fan system, there are additional requirements that must be met to ensure proper operation.

The nature of Variable Frequency Drive systems (VFD) must be considered prior to and during the installation of Big Ass Fans. Due to high frequency electrical noise on the output side of the fan controller, measures must be taken to ensure that wires and cabling are routed in a manner consistent with recommendations made in this section. Big Ass Fans controllers rely on “motor feedback” through the cabling to sense motor speed, slip, etc.

Controller AC supply

Most conventional methods of power distribution and branch circuit installation apply to all models of fan controllers. Installation must comply with speciﬁcations regarding wire types, conductor sizes, branch circuit protection, and disconnecting devices. Failure to do so may result in personal injury and/or equipment damage.

• AC supply feeds for one fan controller can share the same conduit with AC supply feeds for one or more additional controllers.

• AC supply feeds for a fan controller and output/motor leads for the same fan controller cannot share a conduit.

• AC supply feeds for one fan controller cannot share conduit with output/motor leads from one or more additional controllers/VFDs.

• Any unused conductors that share a conduit with an AC supply feed should be grounded on both ends to prevent risk of electric shock due to induced voltages.

• Output/motor leads for a fan controller and AC supply feeds for the same fan controller cannot share a conduit.

• Output/motor leads for one fan controller cannot share conduit with AC supply feeds or output/motor leads from one or more additional fan controllers.

• Any unused conductors that share a conduit with fan controller output/motor leads should be grounded on both ends to prevent risk of electric shock due to induced voltages.

Power wiring guidelines

In order to satisfy some code requirements, it may be necessary to install a manual disconnect at the fan motor location when the fan assembly is not within “line-of-sight” from the fan controller. A non-fused, 600 V, 3-phase, blade-style disconnect should be used to satisfy this “line-of-sight” requirement.

WARNING: Installation must comply with speciﬁcations from National Electrical Codes and standards (NEC, VDE, BSI, etc.) regarding wire types, conductor sizes, branch circuit protection, and disconnecting devices.

WARNING: To avoid a possible shock hazard and/or nuisance tripping caused by induced voltages, unused wires in the conduit must be grounded at both ends. For the same reason, fan controller output wires should not share a conduit with another fan controllers output leads, or other power circuits.

CAUTION: MC or “Metal clad” cable cannot be used for controller output/motor leads. Both stranded and solid core varieties must be avoided. Do not use solid core cable of any size or insulation class for motor wiring. Use of such types of cabling may result in nuisance tripping or premature equipment failure.

ATTENTION

Page 32

A variety of cable types are acceptable for variable frequency drive installations. For many installations, unshielded cable is adequate if it can be separated from sensitive circuits. In all cases, parallel runs of control and motor

cabling should be avoided when unshielded cable is used. Do not use cable with an insulation thickness of less than 15 mils.

• UL installations in 50º C ambient must use 600 V, 75º C or 90º C wire.

• UL installations in 40º C ambient should use 600 V, 75º C or 90º C wire.

Acceptable unshielded types

THHN, THNW, or similar wire is acceptable for drive installations in dry environments if adequate free air space and/or conduit ﬁll rate limits are provided. Do not use THHN or similarly coated wire in wet areas. Any wire chosen must have a minimum insulation thickness of 15 mils and should not have large variations in insulation concentricity.

Acceptable shielded types

The drain conductor included with shielded cables must be connected to both the motor frame and the PE/Ground terminal of the Variable Frequency Drive.

Maximum cable lengths

To prevent nuisance trips, the distance between the controller and the fan should not exceed 400 ft (122 m).

Output disconnects

A device, such as a contactor, that routinely disconnects and reapplies output power to the motor for the purpose of starting and stopping the motor cannot be used.

Recommended wire size

A minimum of 14 AWG is acceptable for motor leads. 14 AWG applies to motor leads only. Power feeders to controllers must be governed by the fuse size included with the fan controller and/or required circuit breaker.

Grounding

The nature of Variable Frequency Drive systems must be considered prior to and during the installation of Big Ass Fans. Due to high frequency content on the output side of the fan controller, measures must be taken to ensure that all grounding connections conform to the recommendations made in this section.

The fan controller’s safety ground conform to the requirements of national and local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be periodically checked. All ground leads for downstream conduit boxes must be kept separate from the motor ground and terminated on the fan controller’s PE terminal.

Motor ground

The motor ground must be connected to a ground terminal on the VFD to aid in keeping high frequency electrical noise o of the building’s ground grid.

Shielded motor cable terminations

Either of the safety ground terminals on the drive provides a grounding point for the motor cable shield. The motor cable shield connected to one of the drive terminals must also be connected to the motor frame. If no drain lead is present, the cable must be stripped back so that the braid can be twisted and soldered to a pigtail for proper termination.

Installing the Electronic Programming Module (EPM)

ATTENTION

If hanging multiple fans, ensure to install the exact EPM included in each fan’s packaging. EPMs are not interchangeable!

CAUTION: Install the EPM prior to applying power to the fan controller!

The Electronic Programming Module (EPM) contains all programming information speciﬁc to fan operation. It must be installed prior to applying power to the fan controller. This module is provided as part of the fan’s accessory kit.

To install the EPM, disconnect the fan from power (refer to the position of the disconnect switch below). Insert the EPM in the location shown below. Note: The EPM can

only be inserted one way. Do not force it!

Wiring: Early Suppression Fast Response (ESFR)

WARNING: Wait three minutes after disconnecting before servicing!

WARNING: Improper installation can cause electric shock or damage to the motor and controller. A qualiﬁed electrician should perform the installation.

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.

The ﬁre relay included with the fan is needed only if the fan will be installed in a building that has a ﬁre sprinkler system. The ﬁre relay integrates the fan with the sprinkler system and shuts down the fan upon receiving an alarm signal from the system. If the building in which the fan will be installed has a sprinkler system, you must install the relay according to the instructions below.

A contact closure across the digital input terminals 4 and 13A will result in fan shutdown. The included relay uses a Normally Open (N.O.) contact as shown below. The relay coil must be energized by the FACP for fan shutdown. Optionally, the normally closed (N.C.) relay contact can be used. The relay coil must remain energized by the FACP for fan operation. This would be considered a fail safe or fail open wiring arrangement. Two additional relay coil leads are provided to facilitate supervision pass-through where required.

Daisy Chaining

WARNING: Wait three minutes after disconnecting before servicing!

The following illustrations and parameter changes enable daisy chaining of the Pivot fan speed controller. The ﬁrst fan provides a start/stop contact and 0–10 VDC analog speed reference for the downstream fan controller. The downstream fan controller provides a new start/stop contact and 0–10 VDC analog speed reference for the following downstream fan controller. This preferred method of linking the fan controllers together ensures minimal signal loss of command signals in larger multi-fan systems.

Assertion Level Switch (ALSW)

The fan controller ships with the onboard digital I/O conﬁgured for Sourcing (PNP) operation. Terminal 4 provides +15 VDC to be used as a supply voltage for user-supplied switches and accessories. For this 3-wire daisy chaining application, the downstream fan controllers must be switched to Sinking (NPN) operation. Terminal 4 will then provide a DC common connection and allow the analog signal and start stop signal to share that common. The

Assertion Level Switch above terminal 4 must be switched from (+) to (-) on all downstream fan controllers for proper daisy chaining operation prior to powerup, parameter changes and operation.

Speed at Max Signal

Change to equal the frequency setting of P103 Maximum Frequency.

Note: Depending on the AWG and distance of the low voltage wiring, the downstream fans may run slightly slower than the leading fan. If this occurs, P161 Speed at Max Signal can be used to introduce a minor command reference overshoot to compensate for the analog voltage drop. At each downstream fan (beginning with the ﬁrst downstream fan), adjust the value of P161 up 0.1 to 0.2 Hz increments until the fan’s output frequency matches that of the lead fan.

PREVENTIVE MAINTENANCE

567

Please take a few moments each year to perform the following preventive maintenance inspection on your fan to ensure its safe and ecient operation. If you have any questions, please contact Customer Service.

WARNING: Risk of ﬁre, electric shock, or injury to persons during cleaning and user-maintenance! Disconnect the appliance from the power supply before servicing.

WARNING: Before servicing or cleaning the fan, switch o power at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device (such as a tag) to the service panel.

WARNING: When service or replacement of a component in the fan requires the removal or disconnection of a safety device, the safety device is to be reinstalled or remounted as previously installed.

Annual preventive maintenance

Note: Actual installation setup may dier from picture.

To be performed annually (see “Maintenance Checklist”):

1. Ensure safety cable is present and securely tightened. The cable should be tightly wrapped around the mounting structure with as little slack as possible. The shackle should be located on the topside of the mounting structure. The shackle’s screw pin should be securely tightened.

2. Ensure all mounting bolts (16x or 12x depending on installation setup) are present and torqued to 40 ft·lb (54.2 N·m).

3. Inspect motor terminations inside junction box and tighten if necessary.

4. Check gear reducer for oil leakage. If leakage is present, contact Customer Service.

5. Ensure all airfoils are secured to one another by airfoil retainers.

6. Ensure all bolts (18x) securing airfoils to fan are present and torqued to 29 ft·lb (47 N·m).

7. Ensure all screws (10x) securing winglets to airfoils are securely tightened.

8. Check guy wires (if installed) for fraying or damage.

General preventive maintenance

• Dust airfoils, motor, and motor housing. If desired, use a gentle cleaner or degreasing agent to polish the airfoils. Do not use Clorox® or other chlorine based cleaners! This could result in the release of toxic/fatal fumes.

• Check all fan controller connections and tighten as needed. Using a vacuum, remove all dust and debris from the inside and outside of the controller.

• Verify proper fan rotation. To be eective, the fan must be turning counterclockwise when viewed from the ﬂoor. To change the direction of the fan’s rotation, see instructions “Operating the fan controller.”

WARNING: Do not operate a fan with missing or damaged components! Please contact Customer Service.

Customers outside of the United States

For questions about your product or customer service inquiries, please contact your local Big Ass Fans representative or ﬁll out a contact form at www.bigassfans.com/service.

Symptom Possible Solution(s)

The fan is turning in the wrong direction. To be eective, the fan should be rotating in the counterclockwise

direction when viewed from the ﬂoor. If the fan is not rotating in the counterclockwise direction, press the F/R button on the controller.

A popping noise is coming from the fan. Airfoil noise comes from airfoils that are not tightened to the speciﬁed torque.

The fan will not start. Verify the following:

The fan controller generates radio frequency noise (RF).

Fan controllers generate RF noise in many ways, but this can be prevented using the proper wiring practices outlined in “Electrical Installation.”

The motor makes noise when fan speed is increased.

Disconnect the fan from power, and then tighten the airfoil fasteners to 29 ft·lb (39.3 N·m). If the popping still occurs, verify that the airfoils are not contacting each other. If they are, contact Big Ass Fans Customer Service.

Make sure that all wires are securely connected. Verify that supply power is adequate and functional. If the fan still does not start, contact Customer Service.

Verify the following:

Do not run your controller and sensitive equipment on the same power line.

Install shielded cables, run leads in grounded metallic conduit, or use appropriate size 4 conductor shielded cable for motor leads.

Ensure proper grounding at the motor, controller, and from the controller to the utility. If the noise is still present, contact Customer Service.

Verify motor currents are within limits. See the fan speciﬁcations on page 1.

Audible high frequency carrier noise may be an indicator of a stall condition.

Note: Some motor, gearbox, or drive noise is to be expected and is normal.
