Note 4. Specific Condition of Use
WARNING
• Electrostatic charge may cause an explosion
hazard. Avoid any actions that cause the
generation of electrostatic charge, such as rubbing
with a dry cloth on coating face of the product.
• In the case where the enclosure of the pressure
transmitter is made of aluminum, if it is mounted
in an area where the use of EPL Ga equipment is
required, it shall be installed in such a way that ,
even in the event of rare incidents, ignition sources
due to impact and friction sparks are excluded.
• When the lightning protector option is specified,
the apparatus is not capable of withstanding the
500 V insulation test required by IEC 60079-11.
This must be taken into account when installing
the apparatus.

Note 2. Electrical Data
• Intrinsically safe ratings are as follows:
Maximum Input Voltage (Ui) = 32 V
Maximum Internal Capacitance (Ci) = 3.52 nF
Maximum Internal Inductance (Li) = 0 μH
Note 3. Installation
• The instrument modification or parts replacement
by other than authorized representative of
Yokogawa Electric Corporation and will void IECEx
Intrinsically safe and type n certification.
• The pressure transmitter is allowed to be installed
in “nL” systems, on condition that the output
parameters of “nL” source (associated energy-
limited apparatus) are suitable to the above
mentioned input parameters of the pressure
transmitter and the cable parameters.
• When installing the transmitter in “ic” FISCO
system or FNICO system, follow the installation
requirements of each system.
• Cable glands, adapters and/or blanking elements
shall be of Ex “n”, Ex “e” or Ex “d” and shall be
installed so as to maintain the specified degree of
protection of the equipment.
• For multiple types of protection, the selected Ex
marking on the marking plate shall be checked at
the time of installation.
