• 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.

• Prior to installation, check that the safety class of this
unit satisfies the system requirements.
• 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

• 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.
