Chapter 22 Flashcards
EMC
Electromagnetic Compatibility
The ability of equipment to
function in a manner that makes
them immune to certain
amounts of electromagnetic
interference (EMI), while keeping
the interference generated by
them within specific limits.
TDMM.* Page G-67
EMI
Electromagnetic Interference
Radiated or conducted
electromagnetic energy that has
an undesirable effect on
electronic equipment or signal
transmissions.
TDMM.* Page G-67
Ingress
1 .An electrical characteristic
associated with externally
generated noise induced into a
cable.
2.A point of entry for a building
or property.
TDMM.* Page G-97
MICE
Mechanical, Ingress,
Climatic/ChemicaI, and
Electromagnetic
An acronym for an
environmentar classification
system that defines the
environment where a
component or device is used.
TDMM.* Page 22-5
SCADA
Supervisory Control And Data
Acquisition
A control system composed of
programmable logic controllers
(PLCs), data inputs to the PLCs
custom software, and electrically
operated circuit system breakers In
the distribution gear. All these
combine to form a system that
allows automatic operation and
monitoring of the electrical system
through control panel
workstations.

concerns and conditions
TDMM.* Page 22-1
How is the factory floor
area defined?
An area beyond the office areas
of an industrial premises where
work areas and automation
island areas already exist
TDMM.* Page 22-7
How is the work area within
an industrial premises
defined?
The area where personnel
monitor, operate, and maintain
machinery and associated
telecom devices
TDMM.* Page 22-1
What is an automation
island area?
A space within an industrial
premises where machinery is
installed, but people are not
normally present during
machinery operation
TDMM.* Page 22-1
True or False
The ICT designer may select
items that are suitable for
OSP applications when
designing the cabling system
for a special occupancy
premises.
True. Special occupancy areas
may require cabling that is not
affected by exposure to severe
climatic conditions. As a result,
the ICT designer may select OSP
components to address these
challenges.
TDMM.* Page 22-2
What type of location
contains flammable or
explosive liquids, vapors,
and dusts that are
generated by industrial
processes and machinery?
Hazardous locations
TDMM.* Page 22-3
Name 3 locations with
exposure to chemically
reactive materials.

storage/distribution facilities
2.Food and beverage processing
facilities
3.General manufacturing
processes that involve the use
of chemically reactive materials
TDMM.* Page 22-3
Name 5 chemically reactive
materials that might be
found in a special
occupancy location.
1 .Acids
2.AIkalis
3.SaIts
4.0rganic materials
5.Gases

Name 4 areas where
EMI/EMC would be a
major concern for the
ICT designer.
1 .Electric generating stations
2.Electric substations
3.High-power radio, radar,
satellite, and TV transmission
facilities
4.Laboratories and test facilities
TDMM.* Page 22-3
Per TIA-1 005, what cable
types are recognized
for use in special
occupancies?
*4-pair category 5e or higher
100-ohm balanced twisted-pair
cabling
02-pair 100-ohm balanced
twisted-pair cabling
*Multimode optical fiber cabling
*Singlemode optical fiber cabling
Bundled and hybrid cabling
TDMM. Page 22-4
What is the primary
purpose of the MICE
classification system?
To describe the industrial
applications where cabling can
be exposed to environments
harsher than those normally
found with the office-oriented or
traditional commercial
building cabling
TDMM.* Page 22-5
Name the 3 basic industrial
areas within an industrial
facility.
1 .Factory floor
2.Work area
3.Machine area
TDMM.* Page 22-5
Which MICE classification
is typically assigned to a
traditional commercial
environment?
MICE 1
TDMM.* Page 22-5
What type of environment
can be classified as a
MICE 2 environment?
A light industrial environment
TDMM.* Page 22-5
What type of environment
can be classified as a
MICE 3 environment?
A heavy industrial environment
TDMM.* Page 22-5
Where is the harshest
environment located within
an industrial control
system?
In the work area and the in the
machine area
TDMM.* Page 22-7
True or False
The cabling system may
cross MICE classification
boundaries.
True. The cabling system may
cross MICE classification
boundaries, but it should be
compatible with the worst-case
MICE environment.
TDMM.* Page 22-9
True or False
MICE classifications are
used to impose
requirements for cabling
components.
False. MICE classifications are
NOT necessarily intended to
impose requirements on
cabling components.

What does an IP code
describe?
The capability of a connector
housing or an outlet box to meet
a specific test condition for
ingress of foreign objects or
water immersion
TDMM.* Page 22-10
What does the x in the IP
code IPxy represent?
The x represents the capability
to resist penetration by
a foreign object.
