SAFE INSTALLATION MANUAL (IECEx / ATEX APPROVAL)
BEFORE USE ....
■SAFETY PRECAUTIONS
This manual describes important points of caution for safe
use of this product in potentially explosive atmosphere.
Please read this manual carefully before installing and op-
erating the product.
■SPECIAL CONDITIONS FOR SAFE USE
• If the model FRC0 is mounted in an area where category 1
equipment is required, precautions have to be taken that
the enclosure can not be charged by static electricity.
• If the model FRC1 is mounted in an area where category
1 equipment is required, it must be installed such that
even in the event of rare incidents, ignition sources due to
impact and friction sparks are excluded.
• When the model FRC0 is installed in environment requir-
ing a higher ingress protection than IP20, it must be ad-
ditionally protected by an enclosure suitable for the envi-
ronment.

WARNING
Explosions could result in death or serious injury:
• The enclosure cover must be fully engaged to meet flame-
proof requirements.
• Do not remove the enclosure cover in explosive atmos-
pheres when the circuit is alive (except IS models).
• Do not connect or disconnect the LCD module in explosive
atmosphere when the circuit is alive.
• When the LCD is not installed, covers shall instead be fit-
ted at the open connectors.
• Before you remove the unit or mount it, or before you con-
nect or disconnect the wiring, turn off the power supply
and the input signal for safety. Do not disconnect unless
the area is known to be non-explosive.
• Whenever you need to measure voltage across the termi-
nals or apply a simulated input signal to the terminals,
make sure that there is no danger of explosion in the at-
mosphere.
• Before connecting a HART communicator in an explosive
atmosphere, make sure the instruments in the loop are
installed in accordance with intrinsically safe field wiring
practices.
• Verify the certification of the product described on the
specification label on the product.
• Verify that the operating atmosphere of the transmitter is
consistent with the appropriate hazardous locations certi-
fications.
• Verify that the environmental temperature is within the
temperature class required for the area.
Failure to follow these installation guidelines could result
in death or serious injury:
• Make sure only qualified personnel perform the installa-
tion.

• Prior to installation, check that the safety class of this
unit satisfies the system requirements.
• A safety barrier must be installed between the unit and
its power supply. Refer to “Installation Diagram” attached
at the end of this manual when selecting a safety barrier.
• The power supply and the safety barrier must be located
in a non-hazardous area.
• Environmental temperature must be within the following
ranges depending upon the required temperature class.
T4 : -40°C ≤ Ta ≤ +80°C
T5 : -40°C ≤ Ta ≤ +65°C
T6 : -40°C ≤ Ta ≤ +50°C
• DO NOT RUB the surface of the plastic enclosure with a
dry cloth. Electrostatic charge generated by the friction
may cause an explosion.
• DO NOT APPLY physical impact or friction onto the
FRC1 enclosure.
• Non-metallic materials (window cement) are contained in
the FRC1/FRC2 enclosure and the user must consider the
performance of these materials with respect to chemicals
which may be present in the hazardous area.
• Be sure to secure the terminal cover after wiring (model
FRC0).
• The wiring method must be in accordance with the electri-
cal parameters described in this manual.
• Be sure to earth the unit (model: FRC1/FRC2).
• The intrinsic safety approval of the model FRC1/FRC2 is
applied to the combination of the outdoor enclosure and
the transmitter. The transmitter must not be separated
or replaced.
• Substitution of components may impair suitability for the
hazardous location and may cause an explosion.
• When metal particles are present in the air, install the
model FRC0 inside an outdoor enclosure.
• For installing the FRC0 in an environment with a high
relative humidity exceeding 0 to 95% RH or in a condens-
ing atmosphere, install the unit inside an outdoor enclo-
sure.

• Use suitable heat resistant cable and cable glands for am-
bient temperatures ≥ 70°C
• Before wiring, make sure there is no danger of explosion
in the atmosphere.
• Before opening the enclosure, wait at least for 60 seconds
after the power is removed.
• The cable entry device and stopping plugs for unused ap-
ertures shall be of a certified flameproof type, suitable for
the conditions of use and correctly installed.
•
The cable entry conduit is 1/2 NPT or M20 ×1.5 threaded.
• Six or more cable entry threads must be engaged.
• Squeeze the cable entry and stopping plug into the con-
duit with the proper tool.
• Before turning the power supply on, be sure to close the
enclosure cover tightly and tighten the fastener as shown
in Figure 1 using a hexagon key wrench. When opening
the enclosure, loosen the fastener first.

• DO NOT RUB the surface of the plastic enclosure with a
dry cloth. Electrostatic charge generated by the friction
may cause an explosion.
• Be sure to earth the unit.
• For external earthing or bonding connection a cable lug
shall be used so that the conductor is secured against
loosening and twisting and that contact pressure is main-
tained.
• The flameproof approval of this unit is applied to the com-
bination of the outdoor enclosure and the transmitter.
The transmitter must not be separated or replaced.
• Substitution of components may impair suitability for the
hazardous location and may cause an explosion.

In any safety barrier, the output current of the barrier must be limited
by a resistor ‘R’ such that Io = Uo / R.
The safety barrier must be certified by an EU approved certification body
to Ex ia IIC. (For Zone 1 and 2, Ex ib IIC barriers are also possible and
then the whole loop becomes ‘ib.’)
In case of isolated barrier, the earth is not required.
Apparatus which is unspecified except that it must not be supplied from
nor contain under normal or abnormal conditions a source of potential
with respect to earth in excess of 250 Volts RMS.
