Unpack the Power Supply System
AMI typically ships the power supply system with many of the external connections already in place.
  1. Remove the power supply system from the packing and place on a sturdy table in proximity to the magnet.
  2. Uncoil the power leads and check that the leads will reach the magnet.
  3. Check the power lead connections on the Model 420, the power supply, and the energy absorber for tightness.

CAUTION
Before operating the magnet, the customer should verify all power supply system connections according to the diagrams provided in the Installation section of the Model 420 manual.

Complete all Connections for the Electronics
All devices should remain in the powered-off condition during the connection.
  1. Connect the external DC power converter to the rear panel of the Model 601 Energy Absorber.
  2. Connect the power cord for the external DC power converter to AC.

    NOTE
    The Model 601 Energy Absorber is immediately powered-on when connected to AC. The system is safe as long as the other components of the system are powered-off and the magnet is in the persistent mode or a discharged state.
  3. Connect the instrumentation cable between the magnet support stand top plate connector and the magnet station connector J7A or J7B on the rear of the Model 420.
  4. Connect the Model 420 to AC.
  5. Unpack the Model 13x Liquid Helium Level Instrument and connect it to AC.
  6. Connect the 9-pin D-sub instrumentation cable between the LHe/Temp connector J8A or J8B on the rear of the Model 420 and the Model 13x Liquid Helium Level Instrument.
  7. Connect the power leads to the vapor-cooled current lead studs at the top plate  of the support stand.
