Be sure to identify the proper wiring diagram for the motor you are installing. If you have difficulty determining the proper wiring diagram for your motor, please contact Maple Leaf Drives Ltd. for as- sistance. If this motor is installed as part of a motor control drive system, connect and protect the motor according to the control manufacturer’s diagram. When using AC motors with frequency inverters, be certain that the motors maximum speed rating is not exceeded. The wiring, fusing and grounding must comply with the National Elec- trical Code or IEC and local codes. Note: If improper rotation direction is detrimental to the load, check the rotation or ‘bump’ the motor prior to coupling the load to the motor shaft. When the motor is coupled to the load and started, it should start quickly and run smoothly. If not, stop the motor immediately and determine the cause. Possible causes are: low voltage at the motor, motor connections are not correct or the load is too heavy. Check the motor current after a few minutes of operation and compare the measured current with the nameplate rating. 3 Phase Single Voltage 460V or 575V 1 2 3 1 2 3 6 4 5 Connection Diagrams 215T and Smaller Y 254T and Larger Δ Wire Color T1, T4 Blue T5, T2 White T6, T3 Orange 3 Phase Single Voltage Connections WARNING: Do not touch electrical connections unless you first ensure that power has been disconnected.
