  • Page 9: Electrically Held Contactor Operation

    The standard electrically held contactor requires an external 120V AC or 240V AC control relay and rectification circuit to control the standard DC closing and hold-in coils on the contactor (see Figure 19). Rockwell Automation Publication 1502-UM060A-EN-P - October 2020...

  • Page 10: Mechanically Latched Contactor Operation

    The electromechanical relay controlled mechanical latch contactor requires external 120V AC or 230V AC control relays and rectification circuit to control the standard DC closing and trip coils on the contactor (when IntelliVAC control module is not used). See Figure Rockwell Automation Publication 1502-UM060A-EN-P - October 2020...

  • Page 11: Contactor Identification

    Chapter 1 Product Description WARNING: The Rockwell Automation® relay control panel (1503C-XXX or 1503E-CXXX) is required for reliable operation of the contactor within its published specifications. The relays break the DC current that is drawn by the closing coil, holding coil, and trip coil. The relays make sure the pick-up and drop out voltages are coordinated with the pick- up and drop out voltages of the contactor.

  • Page 18: Vacuum Bottle Integrity Test

    If no breakdown occurs in the second test, the vacuum bottle is in an acceptable condition. ATTENTION: If one vacuum bottle fails, Rockwell Automation recommends replacing all three vacuum bottles, if the unit has been in service.

  • Page 19: Storage

    If this value is more than 2 mA, it must be added to the 5 mA limit when testing the vacuum bottles. Rockwell Automation does not recommend a DC Hi-pot test. The values that are obtained during the test are not a reliable indication of vacuum bottle integrity.
