F030101.EPS
IMPORTANT
Please install the flow tube to the location where
it is not exposed to direct sunlight and ambient
temperature is –10 to + 60°C (14 to 140°F).
(2) Noise Rejection
IMPORTANT
The instrument should be installed away from
large electrical motors, transformers and other
power sources in order to avoid interference with
the measurement.
(3) Length of Straight Run
To keep accurate measuring, JIS B7554 “Electro
Magnetic Flow Tubes” explains about upstream piping
condition of Magnetic Flow Tubes.
We recommend to our customers about the piping
conditions shown in Figure 3.1.1 based on JIS B7554
and our piping condition test data.
(4) Liquid Conductivity
IMPORTANT
Please avoid to install the flow tube at location
where liquid conductivity is likely to be nonuniform. Because it is possible to have bad
influences to the flow indication by non-uniform
conductivity when a chemical liquid is injected
from upstream side close to the flow tube. When
this occurs, it is recommended that chemical
application ports are installed on the downstream
side of the flow tube. In case chemicals must be
added upstream side, please keep the pipe
length enough so that liquid is properly mixed.

(12) Grounding
IMPORTANT
Improper grounding can have an adverse affect
on the flow measurement. Please ensure that
the instrument is properly grounded.
The electromotive force of the magnetic flow tube is
minute and it is easy to be affected by noise. And also
that reference electric potential is the same as the
measuring fluid potential. Therefore, the reference
electric potential (terminal potential) of the Flow Tube
and the Converter/Amplifier also need to be the same
as the measuring fluid. And moreover, that the potential must be the same with ground.
Please be sure to ground according to Figure 3.1.7.

equal elasticity. In case of optional code/FRG,
please use rubber gasket or others which has
equal elasticity. Be sure the inner diameter of
the gasket does not protrude to inner piping.
(Refer to Table 3.3.8)
(1) Mounting Direction
Please mount the Magnetic Flow Tube matching the
flow direction of the fluid to be measured with the
direction of the arrow mark on the flow tube.
IMPORTANT
NOTE
When installing a size 150mm with JIS F12
(JIS75M) flange, please displace in circumferential direction slightly because the cover of
electrode chamber will interfere against the bolts.
(4) Tightening Nuts
Please tighten the bolts according to Torque Values in
Table 3.3.5. In case of PVC piping, please select
optional code/FRG, use rubber gasket and tighten with
the torque value in Table 3.3.6.
CAUTION
In case of PFA lining type as the lining material
is Fluorocarbon PFA, it is possible that nuts
loose by its character as time passes. Please
tighten the nuts regularly.
Please be sure to tighten the bolts following
prescribed torque values. Please tighten the
flange bolts diagonally with the same torque
values, step by step up to the prescribed torque
value.
If it is impossible to match the direction, please
never remodel to change direction of the terminal box. In case the measuring fluid flows
against the arrow direction, please refer to the
section “Reversing Flow Direction” in the Instruction Manual of AM11 Magnetic Flow Converter.
(2) Mounting Centering Devices
To keep concentricity between the Flow Tube and
pipes, centering devices must be used. Pass two
through-bolts through the four centering devices (two
for each) and lower adjacent holes of both flanges.
(Refer to Figure 3.3.4)
Please give attention to the nominal size and flange
ratings of the centering devices. (Refer to Table 3.3.7)
(3) Positioning Flow Tube
Position the Flow Tube coming in contact four centering devices with Mini-Flanges. At this time, pay
attention to avoid four centering devices come in
contact with Housing. In case stud type of throughbolts are used, position them coming in contact four
centering devices with thread of the bolts. (Refer to
Figure 3.3.4) After positioning the Flow Tube, pass
remaining through-bolts to remaining holes.
Nuts
Please use appropriate
bolts and nuts
according to Process
connection.

3.4Wiring Precautions
This section is described wiring only for flow tube
side. Please see "Wiring" in AM11 Magnetic Flow
Converter Instruction Manual for converter side.
3.4.1Protective Grounding
CAUTION
Please be sure to connect protective grounding
of ADMAG with cable of 2mm2 or larger cross
section in order to avoid the electrical shock to
the operators and maintenance engineers and
prevent the influence of external noise. And
further connect the grounding wire to the
mark (100Ω or less).
3.4.2General Precautions
Please give attention to the followings in wiring.
• Please be sure to fully tighten the terminal box
cover before the power is turned on.
• Please be sure to turn off the power before
opening the terminal box cover.
3.4.3Cable Types
(1) Dedicated Signal Cable(AM011)
The flow signal is transmitted via this dedicated cable.
The cable is constructed with double shielding over the
two conductors, and used heat-resistant vinyl as the
outer jacket material.
Finished diameter:10.5 mm (0.413”)
Maximum length:200 m (660 ft)
Maximum temperature: 80°C (176°F)
CAUTION
• In case the ambient temperature exceeds 50°C
(122°F), please use heat-resistant cable with
maximum allowable temperature of 70°C
(158°F) or above for JIS flameproof type.
• Please pay attention to avoid the cable is
bended excessively.
• Please do not connect cables outdoors in case
of rain to prevent damages from dew formation
and to keep insulation inside the terminal box
of the flow tube.
• Please do not splice the cable between a flow
tube and a converter if it is too short. Please
replace the short cable with the cable which is
appropriate length wholly.
• The all cable ends are to be provided with
round crimp-on terminal.
• The signal cables must be routed in separate
steel conduit tubes or flexible tubes.
•Please keep conduit or flexible tube water-tight
using sealing tape.
•Please ground each of a flow tube and a
converter separately.
• Please cover each shield of the signal cable
with PVC tube or PVC tape to avoid contacting
between two shields; shield and case.
•When waterproof glands or union equipped
waterproof glands are used, the glands must be
properly tightened to keep the box watertight.
Figure 3.4.1 Dedicated Signal Cable AM011
IMPORTANT
If the cable is longer than required, cut off any
extra length, rather coiling it up, and terminate
the conductors as shown in Figure 3.4.2. Avoid
using intermediate terminal boards to extend the
cable length, or this will interrupt the shielding.

3. INSTALLATION
CAUTION
Since A, B, SA, SB, and C all operate at different electrical potentials, securely insulate them
from each other so they do not touch.
The shields must not be allowed to touch each
other or to touch the case.
Cover each shield with vinyl tube or wrap in vinyl
tape.
NOTE
Conductors A and B carry the signal from the
electrodes, and C is at the potentials of the liquid
it self (signal common) . Shields SA and SB are
kept at the same potentials as the individual
electrodes (these are actively driven shields).
This is done to reduce the effect of the distributed capacitance of the cable at long cable
length. Note that, since the signals from the
individual electrodes are impedance converted
inside the converter, errors will result if they
come in contact with any other component.
Great care must be taken in the cable end
treatment.

INSTALLATION AND OPERATING PRECAUTIONS FOR JIS FLAMEPROOF EQUIPMENT
INSTALLATION AND OPERATING PRECAUTIONS FOR
JIS FLAMEPROOF EQUIPMENT
Apparatus Certified Under Technical Criteria
(IEC-compatible Standards)
1.General
The following describes precautions on electrical apparatus
of flameproof construction (hereinafter referred to as
flameproof apparatus) in explosion-protected apparatus.
Following the Labour Safety and Health Laws of Japan,
flameproof apparatus is subjected to type tests to meet either
the technical criteria for explosionproof electrical machinery
and equipment (standards notification 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 certified apparatus can be used in hazardous
locations where explosive or inflammable gases or vapours
may be present.
Certified apparatus includes a certification label and an
equipment nameplate with the specifications necessary for
explosion requirements as well as precautions on explosion
protection. Please confirm these precautionary items and use
them to meet specification 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.
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 flame
caused by explosion does not ignite gases or vapours outside
the enclosure.
In this manual, the word "flameproof" is applied to the
flameproof equipment combined with the types of protection
"e", "o", "i", and "d" as well as flameproof equipment.
3.Terminology
(1) Enclosure
An outer shell of an electrical apparatus, which encloses live
parts and thus is needed to configure 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
flameproof enclosure minus the volume of the internal
components essential to equipment functions.
To meet flameproof requirements, equipment that can be
termed “flameproof” must:
(1) Be certified by a Japanese public authority in accordance
with the Labour Safety and Health Laws of Japan and
have a certification label in an appropriate location on its
case, and
(2) Be used in compliance with the specifications marked on
its certification label, equipment nameplate and
precautionary information furnished.
2.Electrical Apparatus of Flame-
proof Type of Explosion-Protected Construction
Electrical apparatus which is of flameproof construction is
subjected to a type test and certified by the Japanese Ministry
of Labour aiming at preventing explosion caused by electrical
apparatus in a factory or any location where inflammable
gases or vapours may be present. The flameproof
(4) Path length of joint surface
On a joint surface, the length of the shortest path through
which flame flows from the inside to outside of the
flameproof enclosure. This definition 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 classification of the specified gases and vapours.

EX-B03E
INSTALLATION AND OPERATING PRECAUTIONS FOR JIS FLAMEPROOF EQUIPMENT
4.Installation of Flameproof Ap-
paratus
(1) Installation Area
Flameproof apparatus may be installed, in accordance with
applicable gases, in a hazardous area in Zone 1 or 2, where
the specified gases are present. Those apparatus shall not be
installed in a hazardous area in Zone 0.
Note: Hazardous areas are classified 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
flameproof apparatus is limited to an ambient temperature
range from –20°C to +40°C (for products certified under
Technical Criteria). However, some field-mounted
instruments may be certified at an ambient temperature up to
+60°C as indicated on the instrument nameplates. If the
flameproof 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 flameproof
metal conduits for their electrical connections. For cable
wiring, cable glands (cable entry devices for flameproof type)
to wiring connections shall be attached. For metal conduits,
attach sealing fittings 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
flameproof type) specified 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 nonhardening sealant
such as liquid gaskets to those threads for waterproofing.
•Specific 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
flexible 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 fill the ducts with
sand appropriately.
•When branch connections of cables, or cable connections
with insulated cables inside the conduit pipes are made,
a flameproof or increased-safety connection box shall be
used. In this case, flameproof 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
• For the flameproof metal conduit wiring or insulated
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.
•Flameproof sealing fittings shall be used in the vicinity
of the wiring connections, and those fittings shall be
filled with sealing compounds to complete sealing of the
apparatus. In addition, to prevent explosive gases,
moisture, or flame caused by explosion form being
propagated through the conduit, always provide sealing
fittings to complete sealing of the conduit in the
following locations:
(a) In the boundaries between the hazardous and non-
hazardous locations.
(b) In the boundaries where there is a different
classification 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
five-thread engagement to complete tightness. In
addition, since these parallel threads do not have sealing
property, nonhardening sealant such as liquid gaskets
shall thus be applied to those threads for ensuring
waterproofness.
• If metal conduits need flexibility, use flameproof flexible
fittings.

INSTALLATION AND OPERATING PRECAUTIONS FOR JIS FLAMEPROOF EQUIPMENT
6.Maintenance of Flameproof
Apparatus
To maintain the flameproof apparatus, do the following. (For
details, see Chapter 10 “MAINTENANCE OF EXPLOSIONPROTECTED 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 flameproof 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.
(2) Repair
If the flameproof 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
flameproof 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
flameproofness, contact Yokogawa Electric Corporation.
requirements for flameproof apparatus (however, bear in
mind that the apparatus must always be restored to its
original condition). If you attempt to repair the
flameproof apparatus, company-specified components
shall be used.
(d) Before starting to service the apparatus, be sure to check
all parts necessary for retaining the requirements for
flameproof apparatus. For this, check that all screws,
bolts, nuts, and threaded connections have properly been
tightened.
(3) Prohibition of specification changes and
modifications
Do not attempt to change specifications or make
modifications 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 flameproof
type) conforming to IEC Standards are certified in
combination with the flameproof apparatus. So,
Yokogawa-specified cable entry devices for flameproof
type shall be used to meet this demand.
