performed by expert engineer or skilled person-
nel. No operator shall be permitted to perform
procedures relating to installation.
• The magnetic flowmeter must be installed
within the specification conditions.
•The magnetic flowmeter is a heavy instrument.
Be careful that no damage is caused to person-
nel through accidentally dropping it, or by
exerting excessive force on the magnetic
flowmeter. When moving the magnetic flowme-
ter, always use a trolley and have at least two
people carry it.
•When the magnetic flowmeter is processing hot
fluids, the instrument itself may become ex-
tremely hot. Take sufficient care not to get
burnt.
•Where the fluid being processed is a toxic
substance, avoid contact with the fluid and
avoid inhaling any residual gas, even after the
instrument has been taken off the piping line for
maintenance and so forth.
•Do not apply excessive weight, for example, a
person stepping on the magnetic flowmeter.
•All procedures relating to installation must
comply with the electrical code of the country
where it is used.
(2) Wiring
WARNING
•The wiring of the magnetic flowmeter must be
performed by expert engineer or skilled person-
nel. No operator shall be permitted to perform

3.2 Handling Precautions
WARNING
The magnetic flowmeter is a heavy instrument.
Be careful that no damage is caused to person-
nel through accidentally dropping it, or by
exerting excessive force on the magnetic flow-
meter. When moving the magnetic flowmeter,
always use a trolley and have at least two
people carry it.
NOTE
This chapter describes the remote flowtube as
an example. The same attention must be paid to
the integral flowmeter.
3.2.1 General Precautions
(1) Precaution during Transportation
The magnetic flowmeter is packed tightly. When it is
unpacked, pay attention to prevent damaging the
flowmeter. To prevent accidents while it is being
transported to the installing location, transport it to the
site in its original packing.
CAUTION
In order to lift a magnetic flowmeter that is fitted
with eyebolts, proceed as in Figure 3.2.1. Never
lift it using a bar passed through the flowtube as
this damages the liner severely.
Horizontal position Vertical position,
using block and tackle

Figure 3.2.1 Lifting Flowmeter
(2) Avoid Shocks from Impact
CAUTION
Care should be taken not to drop the flowmeter
or expose it to excessive shock. In particular, be
careful not to subject the flange surface to
shock. This may lead to liner damage which will
result in inaccurate readings.
(3) Flange Protection Covers
IMPORTANT
Keep the protective covering (i.e. the corrugated
cardboard or other cushioning material) in place
over the flange except when mounting the
flowmeter to the pipe.

(4) DC Power Connection
When using DC power as the power supply for the
converter, give attention to the following points.
1) Connecting Power Supply
IMPORTANT
Do not connect power supply with reversed
polarities.
L/+ terminal: connect +
N/ – terminal: connect –
IMPORTANT
Do not connect power supply with 100 to 240 V
AC or 100 to 120 V DC in the case of a 24 V
power supply version (power supply code 2).
It will give a damage to the converter.
2) Required Power Supply Voltages
IMPORTANT
When using a 24 V power supply, the specifica-
tion for the supply voltage is 24 V (–15% to
+20%), but the input voltage of the converter
drops due to cable resistance therefore it must
be used within the following ranges.

3) Setting Power Supply Frequency
IMPORTANT
Set the local commercial power frequency in
order to eliminate the effect of induction noise
from the power supply.
Refer to “Chapter 6: Parameter Description” in
the user’s manual of the AXF Integral Flowmeter
[Software Edition] (IM 01E20C02-01E).
Parameter No.: J30 and J31
(5) Grounding
CAUTION
Be sure to connect the protective grounding of
the AXF integral flowmeter with a cable of 2mm2
or larger cross section in order to avoid electrical
shock to the operators and maintenance engi-
neers and to prevent the influence of external
noise.
Connect the grounding wire to the mark.
The grounding should satisfy Class D require-
ments (ground resistance, 100  or less).
In case of TIIS Flameproof type, the grounding
should satisfy Class C requirements (ground
resistance, 10  or less) or class A requirements
(ground resistance, 10  or less).

IMPORTANT
• As this is a transistor contact (insulated type),
give attention to proper voltage and polarity
when wiring.
• Do not apply a voltage larger than 30V DC or a
current larger than 0.2A in order to prevent
damage to the instrument.
• When input filter constant of the electronic
counter is large in relation to the pulse width,
the signal will decrease and the count will not
be accurate.
• If the input impedance of the electronic counter
is large, an induction noise from the power
supply may result in inaccurate counts. Use a
shield cable or sufficiently reduce the input
impedance of the electronic counter within the
electromagnetic flowmeter pulse output specifi-
cation range.
• The active pulse output (Optional code EM)
cannot be used in conjunction with the standard
pulse output.
• When the active pulse output (Optional code
EM) is selected, do not be short-circuit between
the DO+ and DO– terminals to avoid damaging
the instrument.
• When the active pulse output (Optional code
EM) is selected, the range of pulse rate must
be set to 2 pps maximum.
• To avoid communication (BRAIN/ HART)
failure, it is recommended to use the shield
cable.
NOTE
For pulse output from the DO terminals, param-
eters must be set. Refer to “Parameter Descrip-
tion” in the user’s manual of the AXF Integral
Flowmeter [Software Edition] (IM 01E20C02-

AXFA11 Magnetic Flowmeter Remote Converter (IM
01E20C01-01E) or the AXFA14 Magnetic Flowmeter
Remote Converter (IM 01E20C02-01E).
WARNING
The wiring of the magnetic flowmeter must be
performed by expert engineer or skilled person-
nel. No operator shall be permitted to perform
procedures relating to wiring.
CAUTION
Once all wiring is complete, check the connec-
tions before applying power to the instrument.
Improper arrangements or wiring may cause a
unit malfunction or damage.
4.2.1 Wiring Precautions
Be sure to observe the following precautions when
wiring:
CAUTION
• In cases where the ambient temperature
exceeds 50°C (122°F), use external heat-
resistant wiring with a maximum allowable
temperature of 70°C (158°F) or above.
• Do not connect cables outdoors in wet weather
in order to prevent damage from condensation
and to protect the insulation, e.g. inside the
terminal box of the flowtube.
• Do not splice the cable between the flowtube
terminal and the converter if it is too short.
Replace the short cable with a cable that is the
appropriate length.
• All the cable ends must be provided with round
crimp-on terminals and be securely wired.
• The signal cables must be routed in separate
steel conduit tubes 16 (JIS C 8305) or flexible
conduit tubes 15 (JIS C 8309).
• Keep conduits or flexible tubes watertight using
sealing tape.
• Ground the remote flowtube and the converter
separately.
• Cover each shield of the signal cable with vinyl
tube or vinyl tape to avoid contact between two
shields or between a shield and a case.
• When waterproof glands or union equipped
waterproof glands are used, avoid tightening
the glands with an excessive torque.
• Be sure to turn the power off before opening
the terminal box cover.
• Before turning the power on, tighten the
terminal box cover securely.
• The terminal box cover of size 2.5 mm to 1000
mm is locked by the special screw. In case of
opening the terminal box cover, use the hex-
agonal wrench attached. For handling the
locking screw, refer to Figure 4.2.8.
• Be sure to lock the cover of size 2.5 mm to
1000 mm by the special screw using the
hexagonal wrench attached after installing the
cover. For handling the locking screw, refer to
Figure 4.2.20.
• Explosion protected types must be wired in
accordance with specific requirement (and, in
certain countries, legal regulations) in order to
preserve the effectiveness of their explosion
protected features.
•When submersible type or optional code DHC
is selected, waterproof glands, signal and
excitation cables are attached.
In order to preserve the effectiveness of
waterproof features, the terminal box cover and
waterproof glands must not be detached from
flowmeter.
IMPORTANT
Prepare the signal cable and the excitation cable
almost the same length. It is recommended to
lay them together closely.
