DIRECTION 2286865, REVISION 14 LOGIQ™ 7 SERVICE MANUAL
Section 1-2 - Important Conventions 1-21
Section 1-4
EMC, EMI, and ESD
1-4-1 Electromagnetic Compatibility
Electro Magnetic 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 interface from its environment or
when the device produces unacceptable levels of mission to its environment. This interface is often
referred to as radio-frequency or electromagnetic interface (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 Electrostatic Discharge (ESD) Prevention
1-4-3 CE Compliance
The LOGIQ™ 7 unit conforms to all applicable conducted and radiated emission limits and immunity
from electrostatic discharge, radiated and conducted RF fields, magnetic fields and power line transient
requirements.
Applicable standards are: 47CFR Part18, IEC60601-1-2, and 806-13.
NOTE: 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.
WARNINGWARNING
DO NOT TOUCH ANY BOARDS WITH INTEGRATED CIRCUITS PRIOR TO TAKING THE
NECESSARY ESD PRECAUTIONS:
1.) Always connect yourself, via an arm-wrist strap, to the dedicated ground
point located on the rear of the scanner (to the left of the power
connector) or a proper frame ground.
2.) Follow general guide lined for handling of electrostatic sensitive
equipment.
