Also if you are in North America, that motor will spin 20% (6/5). The wiring diagram connects this to L1 and L2 of the three-phase supply, so apparently this is actually a supply with 220V across phases. L1 is Line 1 in and should be connected to one of the "hot" wires, L2 is Line 2 in and should be connected to the other "hot" wire. For example, the diagram may include labels such as “L1”, “L2”, “L3” and “C”. It is extremely important that the new. White is the neutral wire and blue is the ground wire. If the motor has screw posts in the wiring box, there will be an extra screw post, not connected to anything, for connecting leads 2,3,5 together. In this case, that amount is 480 volts. The problem is that the low voltage diagram has a brown wire attached to terminal #3, and for 230 it is to be insulated. All you are doing here is, ignoring the two phases in your 3-phase system and using only one of them. The wiring, fusing and grounding must comply with the Neutral – Gray wire. It provides an easy-to-understand visualization of the connection between the pole windings, load and auxiliaries. Damage will occur if the motor is operated with load for more. 7 A Class Ceiling Fan Connection Diagram. The red and blue could be something else, for example the electromechanical brake. But please consider your Inverter current (ampere) rating same rated or higher than motor FLA. Longer life may be found due to a stronger motor, where as 120 volt motors may heat up more. So if A-B, B-C and C-A are all 240 volts, then A-N and C-N will both be 120 volts, but B-N will be 208 volts. Three-phase motors will almost always have a bundle of wires coming out the side, meant for connections to both incoming line power as well as establishing connections between windings. " Push the starter's "T" terminal wires into the three-phase motor's "T" terminals and tighten the terminal screws with the flat head screwdriver. One is 208-240 volt, singlephase, 3-wire.
