Electromagnetic compatibility (EMC)

1-9-1

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.
1-9-2

Compliance

LOGIQ E9 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, IEC60601–1–2:2001.
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.

Electrostatic discharge (ESD) prevention

DO NOT TOUCH ANY BOARDS WITH INTEGRATED CIRCUITS PRIOR TO TAKING THE
WARNING WARNING
NECESSARY ESD PRECAUTIONS:
1. ALWAYS CONNECT YOURSELF, VIA AN ARM-WRIST STRAP, TO THE ADVISED ESD
CONNECTION POINT LOCATED ON THE REAR OF THE SCANNER (TO THE RIGHT OF
THE POWER CONNECTOR).
2. FOLLOW GENERAL GUIDELINES FOR HANDLING OF ELECTROSTATIC SENSITIVE
EQUIPMENT.
Risk of electrical shock, system must be turned off. Avoid all contact with electrical
WARNING WARNING
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.
If the Shear Wave Option is present, MAKE SURE the LEDs on the Capacitor Pack are
OFF before disconnecting the Capacitor Pack Cables.
