4.6 EMI Reduction
If fields of excessive EMI are known or suspected to be present, consult GE Medical Systems Sales
& Service for recommendations. Consider the following if you attempt to reduce EMI:
•
External field strength decreases rapidly with distance from source of magnetic field.
• External leakage magnetic field of a three-phase transformer is much less than that of a bank
of three single phase transformers of equivalent power rating.
• Large electric motors are a source of substantial EMI.
• High-powered radio signals are a source of EMI.
Maintain good screening of cables and cabinets.
4.7 UPS
The Uninterruptable Power Supply (UPS) provides a consistent power supply to various electrical
components of the system. Also, it continues to provide electrical power to components during a
site-wide power outage so components can be safely shut down. The UPS should be kept at least
one meter (1m) away from sensitive electronics (the PDU does not include sensitive electronics).
