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.
