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.

Input power conditioning

Line reactors should be installed if AC supply is subject to any of the following:

• Low line impedance

• 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)
