1.6 EMC, EMI and ESD

1.6.1 What is EMC?

Electromagnetic compatibility describes a level of performance of a device within its electromagnetic
environment. This environment consists of the device itself and its surroundings including other equipment,
power sources and persons with which the device must interface. Inadequate compatibility results when a
susceptible device fails to perform as intended due interference from its environment or when the device
produces unacceptable levels of emission to its environment. This interference is often referred to as radio–
frequency or electromagnetic interference (RFI/EMI) and can be radiated through space or conducted over
interconnecting power of signal cables. In addition to electromagnetic energy, EMC also includes possible
effects from electrical fields, magnetic fields, electrostatic discharge and disturbances in the electrical power
supply.
For applicable standards please refer to Chapter 2 in the Basic User Manual of the Voluson E-Series
ultrasound system.

1.6.2 Compliance

The Voluson E-Series system conforms to all applicable conducted and radiated emission limits and to
immunity from electrostatic discharge, radiated and conducted RF fields, magnetic fields and power line
transient requirements as mentioned in IEC60601-1-2.
For CE Compliance, it is critical that all covers, screws, shielding, gaskets, mesh, clamps, are in good
Note
condition, installed tightly without skew or stress. Proper installation following all comments noted in this
service manual is required in order to achieve full EMC performance.

1.6.3 Electrostatic Discharge (ESD) Prevention

Warning: DO NOT touch any boards with integrated circuits prior to taking necessary ESD precautions.
1. When installing boards, ESD may cause damage to a board. ALWAYS connect yourself, via an arm-
wrist strap, to the advised ESD connection point located on the rear of the system (to the right of the
power connector).
2. Follow general guidelines for handling of electrostatic sensitive equipment.
Warning: Risk of electrical shock! System must be turned off.
Avoid all contact with electrical contacts, conductors and components.
Always use non-conductive handles designed for the removal and replacement of ESD sensitive parts. All
parts that have the potential for storing energy must be discharged or isolated before making contact.
