Desktop Space
The 510A or 510D Personal Terminal and 513, 515, 610, 615, 715, 4410,  and 4425 terminals can
be located in the equipment room and require space on a desk or table.
The 513, 515, 610, 615, 715, 4410, and 4425 terminals each require approximately 3.2 square
feet of space.  The 510A or 510D with optional keyboard each requires approximately 2.1 square
feet of space.
Optional Equipment Floor and Desktop Space
Refer to the following documents for additional information  on optional equipment  that  can  be
used with the system and that will require floor or desk space.

Wall Space Required
Wall space required in the equipment room depends on the type of cross-connect equipment
being installedÐZ100-type (modular) or 110-type.  The space required also depends on the size
of the system. 
DEFINITYÒCommunications System Generic 1 and Generic 3iÐWiring, 555-
204-111, provides details on the cross-connect hardware.
If existing cross-connect hardware is reused, the space  requirements and hardware requirements
must be detailed in the system floor plan. Contact the Technical Consultant for assistance in
planning for reuse of existing equipment.

							aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaENVIRONMENTAL REQUIREMENTS
Temperature and Humidity
The system equipment should be installed in a well-ventilated area.  Maximum equipment perfor-
mance is obtained at an ambient temperature  between 40 and 120 degrees Fahrenheit (4 and 49
degrees Celsius) for short term operation and up to  110 degrees Fahrenheit (43 degrees Celsius)
for continuous operation.  The relative humidity range is 10 to 95 percent up to 84 degrees
Fahrenheit (29 degrees Celsius).  Above 84 degrees Fahrenheit (29 degrees Celsius), maximum
relative humidity decreases from 95 percent down to 32 percent at 120 degrees Fahrenheit (49
degrees Celsius).  Installations outside these limits may reduce system  life or impede operation.
Table O correlates room temperature with allowable relative humidity.

The system equipment can operate at the maximum short-term operational limits for a period not
to exceed 72 consecutive hours or a total of more than 15 days in a year.  For altitudes above
5,000 feet, reduce the maximum short-term temperature limit by 1 °F for each 1,000 feet of
elevation above 5,000 feet.  At 10,000 feet, for example, the maximum short-term temperature
limit is 115 °F.

							ENVIRONMENTAL REQUIREMENTSaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Air Purity
The cabinet should not be installed in an area where the air may be contaminated with any of the
following:
dExcessive dust, lint, carbon particles, paper fiber contaminants, or metallic contaminants
dCorrosive gases, such as sulfur and chlorine
Lighting
Lighting should be bright enough to allow administration and maintenance personnel to perform
their tasks.  The recommended light intensity level is 50 to 70 footcandles.  This level complies
with the Occupational Safety and Health Act (OSHA) standards.
Noise
In most cases, electrical noise is introduced into the system through trunk or station cables, or
both.  However, electromagnetic fields near the system control equipment may also cause noise
in the system.  Therefore, the system and cable runs should not be placed in areas where a high
electromagnetic field strength exists.  Radio transmitters (AM or FM), television stations, induc-
tion heaters, motors (with commutators) of 0.25 horsepower (187 watts)  or greater, and similar
equipment are leading causes of interference.  Small tools with universal motors are generally not
a problem when they operate on separate power lines.  Motors without commutators, whether
synchronous or asynchronous, generally do not cause interference.
Field strengths below 1.0 volt per meter are unlikely to cause interference.  These weak fields
can be measured by a tunable meter such as the Model R-70 meter manufactured by Electro-
Metrics Division.
Field strengths greater than 1.0  volt per meter can be measured with a broadband meter such as
the HOLADAY
TM HI-3001 meter or the Model EFS-1 meter manufactured by Instruments for
Industry, Inc.
The field strength produced by radio transmitters  can be estimated by dividing the square root of
the emitted power in kilowatts by the distance from the antenna in kilometers.  This yields the
approximate field strength in volts per meter and is relatively accurate for distances greater than
about half a wavelength (150 meters for a frequency of 1000 kHz).

							aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaENVIRONMENTAL REQUIREMENTS
Additional Considerations
Noise and heat produced by the system also affect the selection of equipment location.
Acoustic Noise Levels
The acoustic noise levels for the various cabinet configurations are described below.
With Multi-Carrier Cabinet(s)
The noise produced by a cabinet with five carriers is 51, 53, and 56 dBa at low, medium, and
high fan speeds, respectively, at a distance of 5 feet.
Note:If the system cabinet door is open, there is an additional 1 dBa of noise.  The tape
drive also causes additional noise.  When the tape drive is reading data, there is an
additional 1 dBa of noise.  When the tape recorder is rewinding or fast winding, there
is an additional 2 dBa of noise.
With Single-Carrier Cabinet(s)
The noise produced by the system is as follows:
dOne cabinetÐ 48 dBa at a distance of 5 feet
dTwo cabinetsÐ 50 dBa at a distance of 5 feet
dThree cabinetsÐ 52 dBa at a distance of 5 feet
dFour cabinetsÐ 53 dBa at a distance of 5 feet
Note:If the system cabinet door is open, there is an additional 1 dBa of noise.  The tape
recorder also causes additional noise.  When the tape recorder is reading data, there
is an additional 2 dBa of noise.  When the tape recorder is rewinding or fast winding,
there is an additional 4 dBa of noise.
Heat Dissipation
The amount of heat dissipated by DEFINITY Generic 1 cabinet configurations is described below.
113 
						

							ENVIRONMENTAL REQUIREMENTSaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
With Multi-Carrier Cabinet(s)
A fully-loaded multi-carrier cabinet (five carriers) dissipates approximately 8000 BTUs per hour.
However, the typical average dissipation for a cabinet of three carriers is 5000 BTUs per hour.
With Single-Carrier Cabinet(s)
A stack of four single-carrier cabinets (fully loaded) dissipates approximately 6700 BTUs per
hour.  However, the typical average dissipation for a one-carrier system is 1700 BTUs per hour.
Table P shows the typical average and maximum system power consumption and also the sys-
tem heat dissipation for different size SCC and MCC systems.

POWER AND GROUNDING
General
This section provides information on power, grounding, lightning protection, sneak current protec-
tion, standby power, and wiring requirements for system and associated peripheral equipment
installed in the equipment room.
AC Power Requirements
The following section provides AC power and grounding requirements for DEFINITY Generic 1
and Generic 3 systems.
Multi-Carrier Cabinet System
The customer must provide the main AC distribution panel (panel board).  Any available power
source can be used, as long as the phase or leg provides 120-volt AC or 208-volt AC between
any two legs or phases at the required current drain.  The panel board must be equipped with a
bolt-on 50-amp 120-volt or 208-volt thermal magnetic circuit breaker for each cabinet.  One of the
following panel boards, or equivalent, can be provided:
dQMR fusible panel board by General Electric
dQMB fusible panel board by Square D
dVB5 fusible panel by ITE
dFPD fusible panel by Westinghouse
Each system cabinet, along with the auxiliary cabinet, requires a separate power outlet.  These
outlets must not be shared with other equipment, must not be under switch control, and should
be located outside the cross-connect field area, if possible.  Individual requirements are as fol-
lows:
dPPN cabinet and EPN cabinetÐEach cabinet requires a special 120-volt 60-Hz 50-amp
power outlet (NEMA 5-50R or equivalent) or a special 208-volt 60-Hz 30-amp power
outlet (NEMA L6-30R or equivalent).  The outlet must be located within 10 feet of the
cabinet.
dAuxiliary Cabinet (optional)ÐThis cabinet requires a special 120-volt 60-Hz 20-amp
power outlet (NEMA 5-20R or equivalent) or a special 208-volt 60-Hz 30-amp power
outlet (NEMA L6-30R or equivalent).  The outlet must be located within 12 feet of the
cabinets.
115 
						

							POWER AND GROUNDINGaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Figure 15 depicts a typical power and grounding layout for colocated PPN and EPN cabinets.  A
ground wire from the ground block on the EPN cabinet connects to the single-point ground block
on the PPN cabinet.  A 6-AWG ground wire connects the single-point ground block on the PPN
cabinet to an approved ground.  (Also see ``Grounding, later in this section).
Note that the AC powering for a multi-carrier cabinet is as shown in Figure 15 for the PPN
cabinet.
