Cart Grounding
The following diagrams show the correct grounding
connections for the G2 and UniBody carts.
UniBody Cart with 500VA Isolation Power
Supply
An isolation power supply must always be used in the
following situations:
• ECR and VQ desktop systems used "within the
patient environment".
NOTE:
The "patient environment" is defined as a six
foot/183cm sphere around the patient, by all United
States and International safety standards for medical
equipment.
• ECR and VQ portable (laptop) systems where an
attached printer is within the patient environment.
UniBody Cart with Power Strip
In a configuration where an isolation power is not
required, all system components must be plugged into
the medical grade power strip.
The isolation power supply may NOT be required in the
following situations>
• ECR and VQ desktop systems where the base system
is located outside of the patient environment.
• ECR and VQ portable (laptop) systems where the
laptop power supply meets applicable leakage current
specifications, and where an attached printer is
outside of the patient environment.
