1. System Installation Requirements
This section describes installation requirements such as environmental conditions,
required space and layout considerations, power consumption, cabling and grounding.
Jan. 22, 2021-00

1. System Installation Requirements 1-2
TI 32P51J10-01EN
1.1 Control Room Design
Control rooms, in which the system control equipment is to be installed, should be
designed in accordance with the following conditions:
General
In designing a control room, ensure adequate oor strength and air conditioning including dust-
and moisture-proong.
SEE
ALSO
• 1.1 Control Room Design Air Conditioner
• 1.2 Control Room Environment Air Purity
Applied Standards (Table Installation Environment Specications)
 Floor Strength and Space
The oor should have adequate strength, and you should design the layout in accordance with
the weight and size of equipment to be installed.
SEE
ALSO
• For the maintenance space required, refer to 2.4, “Servicing Area.”
• For the weight and dimensions of standard equipment, refer to applicable general specications.
Floor Structure
To prevent damage to cables by operators and maintenance equipment, do not lay cables on the
oor.
Lay cables under the oor as follows:
• Provide an “accessible” oor which also facilitates maintenance work.
• Make cable pits under the oor if it is concrete.
 Flooding- & Dust-proof Floor
To protect equipment and cables, design a ooding-proof oor.
After the cabling is completed, seal all cable conduits using putty to prevent intrusion of dust,
moisture, rats, and insects into the equipment.

1. System Installation Requirements 1-3
TI 32P51J10-01EN
 Clearance From The Wall and The Floor Surface
There are ventilation holes on the front and rear doors of the cabinets. To ensure good air
ventilation and easy maintenance, provide a clearance of at least 1000 mm (including the service
areas) from the wall to the front and rear doors of the cabinets.Also make sure the height of the
ceiling is at least 2400 mm from the oor.

Illumination
The illumination level around a display unit should be 700 to 1500 lx (target illumination level:
1000 lx). The illumination level inside the control room should be reasonably uniform.
Select proper light xtures and install them in positions where they don’t cause glare on the CRT
displays and LCDs.
TIP REFERENCE (Illumination standards):
For ultra-precision work: 1500 to 3000 lx (illumination level: 2000)
For precision work: 700 to 1500 lx (illumination level: 1000)
For ordinary work: 300 to 700 lx (illumination level: 500)
For non-detail work: 150 to 300 lx (illumination level: 200)
Passages, warehouses: 30 to 150 lx (illumination level: 50 to 100)
(Source: JIS Z9110)
Outlets for Maintenance
Outlets (approx. 1.5 kVA) for measurement devices should be provided near the installed
equipment for maintenance.
 Telephone
Telephones should be installed for communications with related stations.
Jan. 22, 2021-00

1. System Installation Requirements 1-4
TI 32P51J10-01EN
 Air Conditioner
The air conditioner should be operated according to the conditions below to prevent moisture
condensation on the installed equipment.
• Keep changes in temperatures within ±10°C/h.
• Install the air conditioner away from the equipment.
• Install substitute air conditioners to prevent moisture condensation as a result of the
temperature rising or falling if an air conditioner fails.
• Set the air conditioner so that its air outlet is not above the equipment (to avoid water
dropping on the equipment).
 Windows
Close the windows of the control room. If a draft comes in around the windows, seal around the
windows.
Opening the window while air conditioning is running may result in condensation forming, or let in
dust or corrosive gas, adversely a󰀨ecting the installed equipment. Windows on the sea side must
be closed to keep out salt air.
Install blinds, if necessary, to prevent sunlight reecting from CRT displays and LCDs.

TI 32P51J10-01EN
1.2 Control Room Environment
This section describes environmental conditions of the control room to operate the
system safely, and stably over a long period of time.
It is recommended that user have the control room environment assessment. For the
assessment, contact Yokogawa if necessary.
 Temperature and Humidity Limits
SEE
ALSO
See “Table of Equipment Installation Specications” in this section, for the temperatures and humidity limits for
operating and storing this equipment.
When bringing the equipment into a location where allowable operating temperature is set
from another location where the temperature exceeds the allowable operating range, following
precautions are necessary:
• The equipment should reach the ambient temperature according to the requirements for the
temperature change rate, keeping it unpacked from its case.At that time, be careful not to
let condensation form on the equipment.
• Once the equipment reaches the allowable operating temperature range, leave it for about
three hours before operation.
Under normal operation, the rate of change of ambient temperatures should be within 10°C/h. All
the equipment should be kept out of direct sunlight.
Condensation
Prevent condensation. If condensation occurs, or its trace is found on the control room, contact
Yokogawa.
SEE
ALSO
See “Section 2.3 Storage” for more information.
Vibration
Vibration in the control room should be limited as follows:
• For vibration frequency up to 8.4 Hz: Limit displacement amplitude to 1.75 mm or less.
• For vibration frequency over 8.4 Hz: Limit acceleration to 4.9 m/s2or less.
The following is the relationship of the vibration frequency, displacement amplitude, and
acceleration:
Acceleration
(m/s2) = 4π2 • A • F2• 10-3
A: Displacement amplitude (mm)
F: Frequency (Hz)
F010201.ai
Consult Yokogawa if complex vibrations are involved.

1. System Installation Requirements 1-6
TI 32P51J10-01EN
 Air Purity
The dust in the control room should be kept below 0.3 mg/m3. Minimize corrosive gas such as
hydrogen sulde (H2S), sulfur dioxide (SO2), chlorine, and conductive dust such as iron powder
and carbon.
The allowable content of H2S, SO2, or any other corrosive gas varies with temperatures, humidity,
or existence of other corrosive gas. Consult Yokogawa if corrosive gas exists.
 Magnetic Field
Do not install the CRT near cables with heavy current owing or in the magnetic eld of a power
supply. If installed in such locations, the display may be distorted or its colors may be a󰀨ected by
the magnetic elds.
 Electric Field Strength (Electric Wave Condition)
For the proper and stable operation of this system, the eld electric strength of the location for the
equipment should be controlled as following:
10 V/m or less (26 MHz to 1.0 GHz)
10 V/m or less (1.4 to 2.0 GHz)
1 V/m or less (2.0 to 2.7 GHz)
In case of the usage of wireless equipment such as transceiver nearby this system, note as
following:
• The door of this system should be closed.
• In case of the usage of transceiver with 10 W or less, the distance from this system should
be kept 1 m or more.
• As for the usage of wireless equipment with 1 W or less such as mobile-telephone, PHS,
wireless telephone or LAN equipment, the distance should be kept 1 m or more.Attention
should be paid to the micro wave radiated from mobile-telephone or PHS even out of usage.
Following formula represents the electric eld strength. However, the calculated value requests
ideal environment. Worse conditioned environment should be taken into consideration. In case
some wireless equipment is used nearby this system, this formula would be useless. The value
calculated through this formula should be considered noting other than reference.
