2.2 Selecting the Installation

Location

The transmitter is designed to withstand severe environmental conditions. However, to ensure stable and accurate operation for years, observe the following precautions when selecting an installation location.

(a) Ambient Temperature

Avoid locations subject to wide temperature variations or a signifi cant temperature gradient. If the location is exposed to radiant heat from plant equipments, provide adequate thermal insulation and/or ventilation.

IM 01C22A01-01E

(b) Ambient Atmosphere

Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a corrosive atmosphere, there must be adequate ventilation as well as measures to prevent intrusion or stagnation of rain water in conduits.

Select an installation site suffering minimum shock and vibration (although the transmitter is designed to be relatively resistant to shock and vibration).

(d) Installation of Explosion-protected Transmitters

Explosion-protected transmitters can be installed in hazardous areas according to the types of gases for which they are certifi ed. See Subsection

2.4 “Installation of Explosion Protected Type

Transmitters.”

IMPORTANT

• Please use a gasket which has a bigger inside diameter than that of gasket facing (ød) on diaphragm seal. In case a gasket which has a smaller inside diameter than that of gasket facing is used, it may cause an error as the gasket prevents diaphragm from working correctly

• During the diaphragm seal installation, ensure as far as possible that no seal liquid head is applied to the diaphragm seals.

• Exercise care so as not to damage diaphragm surfaces. Since the diaphragm protrudes approx.

1mm from the fl ange surface, placing the diaphragm seals with their diaphragm surfaces facing downward may damage the diaphragm surfaces.

• Do not sharply bend or twist capillary tube or apply excessive stress to them.

• Never loosen the four screws securing the cover fl

IMPORTANT

• When measuring the liquid level of the tank, the minimum liquid level (zero point) must be set to a level at least 50 mm above the center of the high pressure side diaphragm seal (see Figure 3.2.3).

• Correctly install the diaphragm seals on the high and low pressure sides of the process, checking the label on each seal.

• To avoid measuring error duets temperature difference between the two diaphragm seals, capillary tube must be bound together. The capillary tube must be securely fi xed to the tank wall to prevent movement by wind or vibration.

If the capillary tube is too long, loosely coil the excess and secure using suitable clamps.

4.1 Impulse Piping Installation

Precautions

The impulse piping that connects the process outputs to the transmitter must convey the process pressure accurately. If, for example, gas collects in a liquid fi lled impulse piping, or the drain of a gas-fi lled impulse piping becomes plugged, the impulse piping will not convey the pressure accurately. Since this will cause errors in the measurement output, select the proper piping method for the process fl uid (gas, liquid, or steam). Pay careful attention to the following points when routing the impulse piping and connecting the impulse piping to the transmitter.

4.1.1 Connecting Impulse Piping to the

Transmitter

(1) Check the High and Low Pressure

Connections on the Transmitter (Figure 4.1)

Symbols “H” and “L” are shown on a capsule assembly to indicate high and low pressure side. Connect the impulse piping to the “H” side, and the low impulse piping to the

“L” side.

(2) Changing the Process Connector Piping

Connections

The impulse piping connection distances can be changed between 51 mm, 54 mm and 57 mm by changing the orientation of the process connectors.

This is convenient for aligning the impulse piping with the process connectors when connecting the piping.

Mounting Bolts

After connecting the impulse piping, tighten the process connector mounting bolts uniformly.

(4) Connecting the Transmitter and 3-Valve

Manifold (EJA110A)

A 3-valve manifold consists of two stop valves to block process pressure and an equalizing valve to equalize the pressures on the high and low pressure sides of the transmitter. Such a manifold makes it easier to disconnect the transmitter from the impulse piping, and is convenient when adjusting the transmitter zero point.

There are two types of 3-valve manifold: the pipe mounting type and the direct-mounting type; care should be taken with respect to the following points when connecting the manifold to the transmitter.

2) Mount the 3-valve manifold on the 50 mm (2-inch) pipe by fastening a U-bolt to its mounting bracket.

Tighten the U-bolt nuts only lightly at this time.

3) Install the pipe assemblies between the 3-valve manifold and the process connectors and lightly tighten the ball head lock nuts. (The ball-shaped ends of the pipes must be handled carefully, since they will not seal properly if the ball surface is scratched or otherwise damaged.)

4.1.2 Routing the Impulse Piping

(1) Process Pressure Tap Angles

If condensate, gas, sediment or other extraneous material in the process piping gets into the impulse piping, pressure measurement errors may result. To prevent such problems, the process pressure taps must be angled as shown in Figure 4.5 according to the kind of fl

uid being measured.

<4. Installing Impulse Piping>

20

NOTE

• If the process fl uid is a gas, the taps must be vertical or within 45° either side of vertical.

• If the process fl uid is a liquid, the taps must be horizontal or below horizontal, but not more than

45° below horizontal.

• If the process fl uid is steam or other condensing vapor, the taps must be horizontal or above horizontal, but not more than 45° above horizontal.

F0405.ai

Figure 4.5 Process Pressure Tap Angle

(For Horizontal Piping)

(2) Position of Process Pressure Taps and

Transmitter

If condensate (or gas) accumulates in the impulse piping, it should be removed periodically by opening the drain

(or vent) plugs. However, this will generate a transient disturbance in the pressure measurement, and therefore it is necessary to position the taps and route the impulse piping so that any extraneous liquid or gas generated in the leadlines returns naturally to the process piping.

• If the process fl uid is a gas, then as a rule the transmitter must be located higher than the process pressure taps.

• If the process fl uid is a liquid or steam, then as a rule the transmitter must be located lower than the process pressure taps.

(3) Impulse Piping Slope

The impulse piping must be routed with only an upward or downward slope. Even for horizontal routing, the impulse piping should have a slope of at least 1/10 to prevent condensate (or gases) from accumulating in the pipes.

(4) Temperature Difference Between Impulse

Piping

If there is a temperature difference between the high and low impulse piping, the density difference of the fl uids in the two lines will cause an error in the measurement pressure. When measuring fl ow, impulse piping must be routed together so that there is no temperature difference between them.

IM 01C22A01-01E

(5) Condensate Pots for Steam Flow

Measurement

If the liquid in the impulse piping repeatedly condenses or vaporizes as a result of changes in the ambient or process temperature, this will cause a difference in the fl uid head between the high pressure and low pressure sides. To prevent measurement errors due to these head differences, condensate pots are used when measuring steam fl ow.

(6) Preventing Wind Speed Effects in Very Low

Differential Pressure Measurement

IMPORTANT

When using a differential pressure transmitter to measure very low pressures (draft pressure), the low pressure connection port is left open to atmospheric pressure (the reference pressure).

Any wind around the differential pressure transmitter will therefore cause errors in the measurement. To prevent this, it will be necessary either to enclose the transmitter in a box, or to connect a impulse piping to the low pressure side and insert its end into a wind excluding pot (cylindrical with a base plate).

If there is any risk that the process fl uid in the impulse piping or transmitter could freeze, use a steam jacket or heater to maintain the temperature of the fl uid.

4.2 Impulse Piping Connection

Examples

Figure 4.6, 4.7, and 4.8 shows examples of typical impulse piping connections. Before connecting the transmitter to the process, study the transmitter installation location, the process piping layout, and the characteristics of the process fl uid (corrosiveness, toxicity, fl ammability, etc.), in order to make appropriate changes and additions to the connection confi gurations.

Note the following points when referring to these piping examples.

• If the impulse piping is long, bracing or supports should be provided to prevent vibration.

• The impulse piping material used must be compatible with the process pressure, temperature, and other conditions.

• A variety of process pressure tap valves (main valves) are available according to the type of connection

(fl anged, screwed, welded), construction (globe, gate, or ball valve), temperature and pressure. Select the type of valve most appropriate for the application.

Precautions

4.3.1 Connecting Process Piping to the

Transmitter

(1) Confi rming the Process Fluid Flow

Direction

The mark “ ” on the manifold indicates the direction in which the process fl uid is fl owed (from right to left).

When connecting the process piping to the process connector, confi rm the process fl uid fl ow direction.

(2) Tightening the Process Connector

Mounting Bolts

The transmitter is shipped with the process connector mounting bolts only loosely tightened. After connecting the process piping, tighten these bolts uniformly to prevent leaks with a torque of 39 to 49 N·m {4 to 5 kgf·m}.

(3) Removing the Process Connector Port

Dustproof Cap

The process connector port threads are covered with a plastic cap to exclude dust. This cap must be removed before connecting the piping. (Be careful not to damage the threads when removing this cap. Never insert a screwdriver or other tool between the cap and port threads to remove the cap.)

4.3.2 Routing the Process Piping

(1) Relationship between Process Fluid and Manifold Locations (For the vertical impulse piping type)

If condensate (or gas) generated in the process piping were allowed to accumulate, then it would be necessary to remove it periodically by opening the drain (or vent) plug. However, this would generate a transient disturbance in the pressure measurement. Therefore, the process piping must be routed so that any condensate (or gas) generated in the process piping will not accumulate in the pressure-sensing assembly of the transmitter.

<4. Installing Impulse Piping>

NOTE

• If the process fl uid is a gas, then as a rule the manifold must be located at the downside of the pressure-sensing assembly.

• If the process fl uid is a liquid, then as a rule the manifold must be located at the upside of the pressure-sensing assembly.

(2) Pipe Size for Process Piping

Use a 15 mm (1/2-inch) pipe for process piping connection to the process connector.

If there is any risk that the process fl uid in the transmitter pressure-sensing assembly could freeze, use a steam jacket or heater to maintain the temperature of the fl uid.

(4) Process Piping Connection Examples

Figure 4.10 shows examples of typical process piping connections. Before connecting the transmitter to the process, study the transmitter installation location, the process piping layout, and the characteristics of the process fl uid (corrosiveness, toxicity, fl ammability, etc.), in order to make appropriate changes and additions to the connection confi gurations.

Note the following points when referring to these piping examples.

• The process piping material used must be compatible with the process pressure, temperature, and other conditions.

• A variety of process piping-mounted stop valves are available according to the type of connection (fl anged, screwed, welded), construction (globe, gate, or ball valve), temperature and pressure.

Select the type of valve most appropriate for the application.

5. Wiring

NOTE

For F OUNDATION Fieldbus and PROFIBUS PA communication types, please refer to manuals in the attached CD-ROM.

IMPORTANT

• Lay wiring as far as possible from electrical noise sources such as large capacity transformers, motors, and power supplies.

• Remove electrical connection dust cap before wiring.

• All threaded parts must be treated with waterproofi ng sealant. (A non-hardening silicone group sealant is recommended.)

• To prevent noise pickup, do not pass signal and power cables through the same ducts.

• Explosion-protected instruments must be wired in accordance with specifi c requirements (and, in certain countries, legal regulations) in order to preserve the effectiveness of their explosionprotected features.

• The terminal box cover is locked by an Allen head bolt (a shrouding bolt) on CENELEC and IECEx fl ameproof type transmitters. When the shrouding bolt is driven clockwise by an Allen wrench, it is going in and cover lock is released, and then the cover can be opened by hand.

When a cover is closed it should be locked by a shrouding bolt without fail. Tighten the shrouding bolt to a torque of 0.7 N·m.

1) Screw the fl ameproof packing adapter into the terminal box until the O-ring touches the wiring port

(at least 6 full turns), and fi rmly tighten the lock nut.

IM 01C22A01-01E

2) Insert the cable through the union cover, the union coupling, the clamp nut, the clamp ring, the gland, the washer, the rubber packing, and the packing box, in that order.

3) Insert the end of the cable into the terminal box.

4) Tighten the union cover to grip the cable. When tightening the union cover, tighten approximately one turn past the point where the cable will no longer move up and down.

Proper tightening is important. If it is too tight, a circuit break in the cable may occur; if not tight enough, the fl ameproof effectiveness will be compromised.

5) Fasten the cable by tightening the clamp nut.

6) Tighten the lock nut on the union cover.

7) Connect the cable wires to each terminal.

25 5.4 Grounding

Grounding is always required for the proper operation of transmitters. Follow the domestic electrical requirements as regulated in each country. For a transmitter with builtin lightning protector, grounding should satisfy ground resistance of 10 Ω or less.

Ground terminals are located on the inside and outside of the terminal box. Either of these terminals may be used.

WARNING

For TIIS fl ameproof type and intrinsically safe, grounding should satisfy Class D requirements

(grounding resistance, 100 Ω or less).

Inc. These tests are required to satisfy either the technical criteria for electrical machinery and equipment in compliance with explosionproof standards involving infl ammable gases or vapors and for machinery and equipment having explosionproof performance (standards notifi cation no. 556 from the Japanese

Ministry of Labor) (hereinafter referred to as technical criteria), in conformity with IEC Standards, or the “Recommended Practice for Explosion-Protected Electrical Installations in General

Industries,” published in 1979. Such a certifi ed apparatus can be used in hazardous locations where infl ammable gases or vapors may be present.

Certifi ed apparatus includes a certifi cation label and an equipment nameplate with the specifi cations necessary for explosion requirements as well as precautions on explosion protection. Please confi rm these precautionary items and use them to meet specifi cation requirements.

For electrical wiring and maintenance servicing, please refer to “Internal Wiring Rules” in the Electrical Installation Technical

Standards as well as “USER’S GUIDELINES for Electrical

Installations for Explosive Gas Atmospheres in General

Industry,” published in 1994.

To meet intrinsically safe requirements, equipment that can be termed an “intrinsically safe apparatus” must:

(1) be certifi ed by the Technical Institute of Industrial Safety,

Inc. in accordance with the Labor Safety and Health Laws of

Japan and have the appropriate mark of certifi cation labeled on its case, and

(2) be used in compliance with the specifi cations marked on its certifi cation label, equipment nameplate and precautionary information furnished.

Note: Intrinsically safe apparatus satisfy their performance under specifi c conditions. They are not always absolutely safe under every operational and environmental condition. In other words, they are not safe products involved with factors such as chemical reactions, geographical changes or the like other than affected by electric energy from the equipment itself.

2. Electrical Apparatus of Intrinsic Safety Type of

Explosion-Protected Construction

The intrinsic safety type of explosion-protected construction is a method of protection applicable to a circuit or part of a circuit in which, under prescribed test conditions, no spark or thermal effect, whether produced normally or accidentally, is capable of causing a prescribed explosive gas to ignite. In other words, electrical apparatus of this construction is intended to suppress electrical energy thereby preventing ignition of a given explosive gas atmosphere even though spark or high thermal effect occurs in the electric circuitry.

Intrinsically safe electrical apparatus generally comprise intrinsically safe apparatus installed in a hazardous location and a safety barrier (associated apparatus), installed in a nonhazardous location, aimed at preventing electrical energy from fl owing into the electric circuitry of intrinsically safe apparatus.

However, battery-operated, portable intrinsically safe apparatus or the like may be used alone.

3. Terminology

(1) Intrinsically safe apparatus: Electrical apparatus in which all the circuits are intrinsically safe circuits.

(2) Associated apparatus: Electrical apparatus in which there are both intrinsically safe circuits and non-intrinsically safe circuits that can affect the safety of intrinsically safe circuits.

(3) Safety barrier: A specifi c type of associated apparatus, which consists mainly of safety barrier elements, and serves to limit the fl ow of excessive electrical energy, which is capable of causing ignition of a given explosive gas or vapour of a non-intrinsically safe circuit into concerned intrinsically safe circuits.

(4) Apparatus of category “ia”: Intrinsically safe electrical apparatus and associated apparatus which are incapable of causing ignition of a given explosive gas or vapour with the appropriate safety factors such as:

- when up to two countable faults are applied and, in addition,

- when non-countable faults produce an onerous condition.

(5) Apparatus of category “ib”: Intrinsically safe electrical apparatus and associated apparatus which are incapable of causing ignition of a given explosive gas or vapour, with the appropriate safety factors such as:

- when up to one countable fault is applied and, in addition,

- when non-countable faults produce an onerous condition.

(6) Safety rating: A rating to be designated to intrinsically safe apparatus as well as associated apparatus and is the maximum rating allowable for maintaining intrinsic safety of concerned intrinsically safe circuits.

4. Caution on Combining Intrinsically Safe

Apparatus and Safety Barriers

(1) A combination of certifi ed intrinsically safe apparatus and safety barriers needs to satisfy combination requirements.

If intrinsically safe apparatus specify safety barriers for combination, safety barriers other than specifi ed cannot be used (see Note 1 for more details).

(2) Certifi ed intrinsically safe systems specify specifi c safety barriers in combination with intrinsically safe apparatus. So safety barriers other than specifi ed cannot be used (see

Note 2 for more details).

(3) Other than limitations of combining intrinsically safe apparatus and safety barriers as given in (1) and (2) above, two or more pieces of apparatus certifi ed under different standards cannot be combined with each other (see Note 3 for more details). In addition, bear in mind that classifi cations of explosion protection such as “IIA,” “IIB” and “IIC” and category “ia” and “ib” limit a combination of intrinsically safe apparatus and safety barriers.

For more details, see the “Type Certifi cate Guide for

Explosion-Protected Construction for Electrical Machinery and Equipment,” issued by the Japanese Ministry of Labour, the Research Institute of Industrial Safety.

Note 1: Testing Apparatus

Intrinsically safe apparatus and safety barriers are assessed individually to ensure that their safety requirements are satisfi ed.

Tested and certifi ed intrinsically safe apparatus and safety barriers incorporate individual certifi cation numbers.

A combination of intrinsically safe apparatus and safety barriers involves the following two limitations:

EX-A03E

<Installation and Operating Precautions for TIIS Intrinsically Safe Equipment>

(1) A safety barrier which meets the combination requirements by referring to its safety rating and combination parameters shall be selected.

(2) For pressure transmitters, pH transmitters, temperature detectors and the like, safety barriers that can be combined are already specifi ed. Other safety barriers cannot be used.

Note 2: Testing Intrinsically Safe System

An assembly (as a system) in which intrinsically safe apparatus and safety barriers are combined is assessed to ensure that its safety requirements are satisfi ed. A tested and certifi ed system incorporates a certifi cation number (intrinsically safe apparatus and safety barriers have the same certifi cation number).

Note 3: Impossible Combinations of Apparatus Certifi ed Under Different

Standards

Intrinsically safe apparatus certifi ed under technical criteria and safety barriers certifi ed under the “Recommended Practice for

Explosion-Protected Electrical Installations in General Industries”

(1979) and vice versa cannot be combined even if their combination requirements are satisfi ed.

5. Installation of Intrinsically Safe Apparatus and

Safety Barriers

(1) Classifi cation of installation location

Intrinsically safe apparatus may be installed, depending upon applicable gases, in a hazardous area in Zone 0, 1 or 2 (Note 4 below), where the specifi ed gases are present. However, note that apparatus certifi ed under Technical Criteria, in category “ib” shall be installed only in Zone 1 or 2. Safety barriers (associated apparatus) that are combined with these intrinsically safe apparatus shall be installed only in a non-hazardous area. In cases where safety barriers are installed in a hazardous area, they shall be enclosed, for example, in a fl ameproof enclosure.

Note 4: Hazardous areas are classifi ed in zones based upon the frequency of the appearance and the duration of an explosive gas atmosphere as follows:

Zone 0: An area in which an explosive gas atmosphere is present continuously or is present for long periods.

Zone 1: An area in which an explosive gas atmosphere is likely to occur in normal operation.

Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation and if it does occur it will exist for a short period only.

(2) Ambient temperature limits for intrinsically safe apparatus

Intrinsically safe apparatus shall be installed in a location where the ambient temperature ranges from –20° to +40°C (for those certifi ed under Technical Criteria) or –10° to +40°C (for those certifi ed under the “Recommended Practice for Explosion-

Protected Electrical Installations in General Industries” (1979).

However, some fi eld-mounted intrinsically safe apparatus may be used at an ambient temperature up to 60°C. So, specifi cations should be checked before installing intrinsically safe apparatus.

If the intrinsically safe apparatus are exposed to direct sunshine or radiant heat from plant facilities, appropriate thermal protection measures shall be taken.

CAUTION

If intrinsically safe apparatus and safety barriers require maintenance service and checking, a gas detector shall be used to ensure that there is no explosive gas in the location

(maintenance servicing shall be conducted in a nonhazardous location).

33

(a) refer to the equipment confi guration diagram and make electrical wiring properly;

(b) prevent intrinsically safe wiring from being contacted with non-intrinsically safe wiring, and separate the intrinsically safe circuit from other electrical circuits;

(c) prevent intrinsically safe wiring from being electrostatically and magnetically affected by non-intrinsically safe wiring;

(d) reduce wiring inductance and capacitance produced between the intrinsically safe apparatus and safety barrier where possible, and use a shorter cable between the intrinsically safe apparatus and safety barrier than specifi ed if the maximum permissible inductance of the cable is specifi ed as operating conditions;

(e) conform to conditions of installation such as wiring method, earthing or the like, if any; and

(f) protect the outer sheath of cables from damage with appropriate measures.

7. Maintenance and Inspection of Intrinsically Safe

Apparatus and Safety Barriers

Maintenance and inspection of intrinsically safe apparatus and safety barriers shall be limited to within the instructions described in applicable instruction manuals. If other than this is required, contact the manufacturers. For more information, refer to the

“USER’S GUIDELINES for Electrical Installations for Explosive

Gas Atmospheres in General Industry” issued in 1994 by the

Japanese Ministry of Labour, the Research Institute of Industrial

Safety.

(1) Requirements for maintenance personnel

Maintenance and inspection of intrinsically safe apparatus and safety barriers shall be conducted by maintenance personnel skilled in intrinsically safe construction and installation of electrical devices as well as capable of applying associated rules.

(2) Maintenance and Inspection

(a) Visual inspection

Visually inspect the external connections of intrinsically safe apparatus and safety barriers, and cables for damage or corrosion as well as other mechanical and structural defects.

(b) Adjustments

Zero, span and sensitivity adjustments shall be made with applicable adjusting potentiometers and mechanical adjustment screws.

These maintenance adjustments shall be made in a nonhazardous location.

6. Wiring for Intrinsically Safe Circuits

In intrinsically safe construction, safety shall be maintained as an intrinsically safe system involving intrinsically safe apparatus and safety barriers connected thereto, and electrical wiring

(through intrinsically safe circuits) interconnected between them.

In other words, even when safety requirements are maintained individually by intrinsically safe apparatus and safety barriers, they shall not be affected by electrical or magnetic energy caused by electrical wiring.

To make electrical wiring for intrinsically safe circuits, you must:

(3) Repair

Intrinsically safe apparatus and safety barriers shall be repaired by manufacturers.

(4) Prohibition of modifi cations and specifi cation changes

Do not attempt to make modifi cations or change specifi cations which may affect safety.

Installation and Operating Precautions for TIIS Flameproof Equipment

Apparatus Certifi ed Under Technical Criteria (IEC-compatible Standards)

34

1. General

The following describes precautions on electrical apparatus of fl ameproof construction (hereinafter referred to as fl ameproof apparatus) in explosion-protected apparatus.

Following the Labour Safety and Health Laws of Japan, fl ameproof apparatus is subjected to type tests to meet either the technical criteria for explosionproof electrical machinery and equipment (standards notifi cation no. 556 from the Japanese

Ministry of Labour) (hereinafter referred to as technical criteria), in conformity with the IEC Standards, or the “Recommended

Practice for Explosion-Protected Electrical Installations in

General Industries,” published in 1979. These certifi ed apparatus can be used in hazardous locations where explosive or infl ammable gases or vapours may be present.

For electrical wiring and maintenance servicing, please refer to “Internal Wiring Rules” in the Electrical Installation Technical

Standards as well as “USER’S GUIDELINES for Electrical

Installations for Explosive Gas Atmospheres in General

Industry,” published in 1994.

To meet fl ameproof requirements, equipment that can be termed

“fl ameproof” must:

(1) Be certifi ed by a Japanese public authority in accordance with the Labour Safety and Health Laws of Japan and have a certifi cation label in an appropriate location on its case, and

(2) Be used in compliance with the specifi cations marked on its certifi cation label, equipment nameplate and precautionary information furnished.

2. Electrical Apparatus of Flameproof Type of

Explosion-Protected Construction

Electrical apparatus which is of fl ameproof construction is subjected to a type test and certifi ed by the Japanese Ministry of Labour aiming at preventing explosion caused by electrical apparatus in a factory or any location where infl ammable gases or vapours may be present. The fl ameproof construction is of completely enclosed type and its enclosure shall endure explosive pressures in cases where explosive gases or vapours entering the enclosure cause explosion. In addition, the enclosure construction shall be such that fl ame caused by explosion does not ignite gases or vapours outside the enclosure.

In this manual, the word "fl ameproof" is applied to the fl ameproof equipment combined with the types of protection "e", "o", "i", and

"d" as well as fl ameproof equipment.

3. Terminology

(1) Enclosure

An outer shell of an electrical apparatus, which encloses live parts and thus is needed to confi gure explosion-protected construction.

(2) Shroud

A component part which is so designed that the fastening of joint surfaces cannot be loosened unless a special tool is used.

(3) Enclosure internal volume

This is indicated by:— the total internal volume of the fl ameproof enclosure minus the volume of the internal components essential to equipment functions.

(4) Path length of joint surface

On a joint surface, the length of the shortest path through which fl ame fl ows from the inside to outside of the fl ameproof enclosure. This defi nition cannot be applied to threaded joints.

(5) Gaps between joint surfaces

The physical distance between two mating surfaces, or differences in diameters if the mating surfaces are cylindrical.

Note: The permissible sizes of gaps between joint surfaces, the path length of a joint surface and the number of joint threads are determined by such factors as the enclosure’s internal volume, joint and mating surface construction, and the explosion classifi cation of the specifi ed gases and vapours.

4. Installation of Flameproof Apparatus

(1) Installation Area

Flameproof apparatus may be installed, in accordance with applicable gases, in a hazardous area in Zone 1 or 2, where the specifi ed gases are present. Those apparatus shall not be installed in a hazardous area in Zone 0.

Note: Hazardous areas are classifi ed in zones based upon the frequency of the appearance and the duration of an explosive gas atmosphere as follows:

Zone 0: An area in which an explosive gas atmosphere is present continuously or is present for long periods.

Zone 1: An area in which an explosive gas atmosphere is likely to occur in normal operation.

Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation and if it does occur it will exist for a short period only.

(2) Environmental Conditions

The standard environmental condition for the installation of fl ameproof apparatus is limited to an ambient temperature range from –20°C to +40°C (for products certifi ed under Technical

Criteria). However, some fi eld-mounted instruments may be certifi ed at an ambient temperature up to +60°C as indicated on the instrument nameplates. If the fl ameproof apparatus are exposed to direct sunshine or radiant heat from plant facilities, appropriate thermal protection measures shall be taken.

5. External Wiring for Flameproof Apparatus

Flameproof apparatus require cable wiring or fl ameproof metal conduits for their electrical connections. For cable wiring, cable glands (cable entry devices for fl ameproof type) to wiring connections shall be attached. For metal conduits, attach sealing fi

ttings as close to wiring connections as possible and completely seal the apparatus. All non-live metal parts such as the enclosure shall be securely grounded.

For details, see the “USER’S GUIDELINES for Electrical

Installations for Explosive Gas Atmospheres in General

Industry,” published in 1994.

(1) Cable Wiring

• For cable wiring, cable glands (cable entry devices for fl ameproof type) specifi ed or supplied with the apparatus shall be directly attached to the wiring connections to complete sealing of the apparatus.

• Screws that connect cable glands to the apparatus are those for G-type parallel pipe threads (JIS B 0202) with no sealing property. To protect the apparatus from corrosive gases or moisture, apply non-hardening sealant such as liquid gaskets to those threads for waterproofi ng.

EX-B03E

<Installation and Operating Precautions for TIIS Flameproof Equipment>

• Specifi c cables shall be used as recommended by the

“USER’S GUIDELINES for Electrical Installations for

Explosive Gas Atmospheres in General Industry,” published in 1994.

• In necessary, appropriate protective pipes (conduit or fl exible pipes), ducts or trays shall be used for preventing the cable run (outside the cable glands) from damage.

• To prevent explosive atmosphere from being propagated form Zone 1 or 2 hazardous location to any different location or non-hazardous location through the protective pipe or duct, apply sealing of the protective pipes in the vicinity of individual boundaries, or fi ll the ducts with sand appropriately.

• When branch connections of cables, or cable connections with insulated cables inside the conduit pipes are made, a fl ameproof or increased-safety connection box shall be used. In this case, fl ameproof or increased-safety cable glands meeting the type of connection box must be used for cable connections to the box.

(2) Flameproof Metal Conduit Wiring the wires shall be used as recommended by the USER’S

GUIDELINES for Electrical Installations for Explosive Gas

Atmospheres in General Industry, published in 1994.

• For conduit pipes, heavy-gauge steel conduits conforming to

JIS C 8305 Standard shall be used.

sealing the wiring connections, and those fi ttings shall be fi lled with sealing compounds to complete sealing of the apparatus.

In addition, to prevent explosive gases, moisture, or fl ame caused by explosion form being propagated through the conduit, always provide sealing fi ttings to complete sealing of the conduit in the following locations:

(a) In the boundaries between the hazardous and nonhazardous locations.

(b) In the boundaries where there is a different classifi cation of hazardous location.

• For the connections of the apparatus with a conduit pipe or its associated accessories, G-type parallel pipe threads (JIS

B 0202) shall be used to provide a minimum of fi ve-thread engagement to complete tightness. In addition, since these parallel threads do not have sealing property, non-hardening sealant such as liquid gaskets shall thus be applied to those threads for ensuring waterproofness.

• If metal conduits need fl exibility, use fl ameproof fl exible fi

ttings.

(2) Repair

If the fl ameproof apparatus requires repair, turn off the power and transport it to a safety (non-hazardous) location. Observe the following points before attempting to repair the apparatus.

(a) Make only such electrical and mechanical repairs as will restore the apparatus to its original condition. For the fl ameproof apparatus, the gaps and path lengths of joints and mating surfaces, and mechanical strength of enclosures are critical factors in explosion protection.

Exercise great care not to damage the joints or shock the enclosure.

(b) If any damage occurs in threads, joints or mating surfaces, inspection windows, connections between the transmitter and terminal box, shrouds or clamps, or external wiring connections which are essential in fl ameproofness, contact

Yokogawa Electric Corporation.

CAUTION

35

Do not attempt to re-process threaded connections or refi nish joints or mating surfaces.

(c) Unless otherwise specifi ed, the electrical circuitry and internal mechanisms may be repaired by component replacement, as this will not directly affect the requirements for fl ameproof apparatus (however, bear in mind that the apparatus must always be restored to its original condition).

If you attempt to repair the fl ameproof apparatus, companyspecifi ed components shall be used.

(d) Before starting to service the apparatus, be sure to check all parts necessary for retaining the requirements for fl ameproof apparatus. For this, check that all screws, bolts, nuts, and threaded connections have properly been tightened.

(3) Prohibition of specifi cation changes and modifi cations

Do not attempt to change specifi cations or make modifi cations involving addition of or changes in external wiring connections.

7. Selection of Cable Entry Devices for Flameproof

Type

IMPORTANT

The cable glands (cable entry devices for fl ameproof type) conforming to IEC Standards are certifi ed in combination with the fl ameproof apparatus. So, Yokogawa-specifi ed cable entry devices for fl ameproof type shall be used to meet this demand.

To maintain the fl ameproof apparatus, do the following. (For details, see Chapter 10 “MAINTENANCE OF EXPLOSION-

PROTECTED ELECTRICAL INSTALLATION” in the USER’S

GUIDELINES for Electrical Installations for Explosive Gas

Atmospheres in General Industry.)

(1) Maintenance servicing with the power on.

Flameproof apparatus shall not be maintenance-serviced with its power turned on. However, in cases where maintenance servicing is to be conducted with the power turned on, with the equipment cover removed, always use a gas detector to check that there is no explosive gas in that location. If it cannot be checked whether an explosive gas is present or not, maintenance servicing shall be limited to the following two items:

(a) Visual inspection

Visually inspect the fl ameproof apparatus, metal conduits, and cables for damage or corrosion, and other mechanical and structural defects.

(b) Zero and span adjustments

These adjustments should be made only to the extent that they can be conducted from the outside without opening the equipment cover. In doing this, great care must be taken not to cause mechanical sparks with tools.
