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

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...

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....

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...

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...

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.

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...
