IM 01C25F01-01E
Note 5. Special Conditions for Safe Use
WARNING
• When the enclosure of the Pressure
Transmitter is made of aluminum, if it
is mounted in an area where the use of
category 1G 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.
• Electrostatic charges on the coated parts of
Pressure Transmitter shall be avoided.
• Electrostatic charge may cause an exlosion
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 case of the enclosure of the Pressure
Transmitter with paint layers, if it is mounted
in an area where the use of category 2D
equipment is required, it shall be installed
in such a way that the risk from electrostatic
discharges and propagating brush
discharges caused by rapid flow of dust is
avoided.
b. ATEX Flameproof Type
Caution for ATEX flameproof type.
Note 1. EJX/EJA-E Series pressure transmitters
with optional code /KF22 are applicable
for use in hazardous locations. For output

Note3. For combined approval types Once a
device of multiple approval type is installed,
it should not be re-installed using any other
approval types. Apply a permanent mark in
the check box of the selected approval type
on the ertification label on the transmitter to
distinguish it from unused approval types.
Note 4. Installation
• All wiring shall comply with local installation
requirement.
• In order to prevent the earthing conductor
from loosening, the conductor must be
secured to the terminal, tightening the screw
with appropriate torque. Care must be taken
not to twist the conductor.
• Cable glands, adapters and/or blanking
elements with a suitable IP rating shall
be of Ex d IIC/Ex tb IIIC certified by ATEX
and shall be installed so as to maintain the
specific degree of protection (IP Code) of the
equipment.
