If you are unfamiliar or uncomfortable with installing electricalcomponents, do not attempt to install the fan without an electrician. Serious personal injury or damage to the fan and other equipmentcould result. This guide is merely a recommendation of proper installation. Adhering to national and local electric codes is yourmandatory 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 routethe cabling through conduit, how to properly ground the fan system, how to properly wire the fan controller, how to properly wire the fanmotor, and proper startup procedures.Controller storageStore 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 frompower for more than one year, apply AC supply power to the controller for a period of two hours prior to operation in order to reconditionthe internal DC bus capacitors.Power requirements for fan controllersThe power requirements for fan controllers are listed in the table on p. 2. If multiple controls are connected to one feeder circuit, thecircuit required is the sum of the feeder circuit requirements listed on the chart. This type of installation will also require that each fancontrol be installed downstream from a dedicated over-current protection device.Mounting the wall controllerIf you are mounting the controller to the fan motor frame instead of the wall (onboard VFD option), skip this section andrefer to the mounting instructions that came with the wall controller and hardware for the onboard VFD.Mount the controller to a wall using a #8–#10 screw. Adhere to the following guidelines when selecting the controller location: 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, moisture, 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.1 HP Controller6.25” (159 mm)5.95” (151 mm)2 HP Controller6.25” (159 mm)5.95” (151 mm)WARNINGSCA MEWARNINGSCA ME10.9” (277 mm)9.5” (241 mm)MR F1 2 5 6 25 4 1113A13B13C14 14 3016 17L1PEL1 L2 L2 L35.51” (140 mm)MR F1 2 5 6 25 4 1113A13B13C 14 30 16 17L1PEL1 L2 L2 L39.5” (241 mm)10.9” (277 mm)7.3” (185 mm)L3L3WWW.BIGASSFANS.COM ©2012 DELTA T CORP.
