Startup from an extended shutdown

About this task

Use these steps if you have performed an Extended shutdownprocedure.

Important: The equipment room is typically used by service engineers to service the equipment. Use caution when inside the equipment room.
Important: Do NOT open any GE MRI System Cabinets or protective covers. There are dangerous high voltages within the cabinets. There are several Cabinets and components within the equipment room used by the GE MRI System.

The Main Disconnect Panel (MDP) is the incoming Power for the MRI System and Cryogen Cooler. Do NOT turn off power to this component. The Cryogen Cooler cabinet must remain on to keep the helium at the proper temperature to maintain correct magnet pressure.

  • The ISC cabinet contains the system PDU and Gradient PDU.
  • The ICC contains the Cryogen Cooler.

Step-by-step instructions
