Chapter 1 Introduction 1 - 15
Section 1-4
EMC, EMI, and ESD
1-4-1 Electromagnetic Compatibility (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.
1-4-2 CE Compliance
The
LOGIQ™ 180
unit 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.
Applicable standards are: 47CFR Part 18, IEC 601–1–2, and 806–13.
For CE Compliance, it is critical that all covers, screws, shielding, gaskets, mesh, clamps, are in
good 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.
1-4-3 EMC Performance
All types of electronic equipment may characteristically cause electromagnetic interference with other
equipment, either through air or connecting cables. The term EMC (Electromagnetic Compatibility)
indicates capability of the equipment, which curbs electromagnetic influence from other equipment and
at the same time does not affect other equipment with similar electromagnetic radiation from itself.
This product is designed to fully comply with the EN60601-1-2 (IEC601-1-2), in Medical electrical
equipment EMC regulations.
Proper installation following this service manual is required in order to achieve the full EMC
performance of the product.
The product must be installed as stipulated in 1-4-4, Notice upon Installation of Product.
In case of issues related to EMC, please follow procedures stated in 1-4-6, Countermeasures against
EMC-related Issues.
1-4-4 Notice Upon Installation of Product
1.) Use either power supply cords provided by GEMS or ones approved by GEMS. Products equipped
with power source plug should be plugged into the fixed power socket which has the protective
grounding conductor
2.) Connect a three-pin plug to a three-pin socket without using a three-pin-to-two-pin converter.
3.) Keep the equipment as far as possible from other electronic equipment.
4.) Be sure to use the only cables provided by GEMS or ones approved by GE Wuxi. Install the unit/
peripherals as per the installation procedure provided in Chapter 3 - INSTALLATION. The layout of
the LOGIQ™ 180 & other peripherals should be as per installation procedures described in Chapter
3 - INSTALLATION.
