Figure 2-4 Motor Connections without Output Contactor
See Appendix C For Recommended Terminal Tightening Torques
A motor circuit contactor is recommended to provide a positive disconnection to prevent motor
rotation which could pose a safety hazard to personnel or equipment. Open the Enable input to J1
terminal strip at least 20 msec before main M-contacts open to prevent arcing at contacts. This
greatly increases contactor life and allows use of IEC rated contactors. See Figure 2-5 for motor
connection with M-contactor.
