2.4 Selecting the Installation Location
The transmitter is designed to withstand severe
environmental conditions. However, to ensure
that it will provide years of stable and accurate
performance, take the following precautions when
selecting the installation location.
(a) Wireless Communication
NOTE
The installation location of this transmitter must
meet the following conditions:
- Adjust the direction of the antenna to be
in the upright position regardless of the
orientation of this transmitter. See section 4
for adjusting the antenna.
- Install the transmitter at least 1.5m above the
ground or oor.
- Ensure that there are no obstacles such as
walls or pipes within a 30-cm radius of each
antenna.
- Conrm that each eld wireless equipment
compliant with ISA100.11a can see the
antenna of other devices which locate within
its own communication range. In the star
topology network, the visibility to the antenna
of gateway is a mandatory clause.
(b) Ambient Temperature
Avoid locations subject to wide temperature
variations or a signicant temperature gradient.
If the location is exposed to radiant heat from
plant equipment, provide adequate thermal
insulation and/or ventilation.
(c) Ambient Atmosphere
Do not install the transmitter in a corrosive
atmosphere. If this cannot be avoided, there
must be adequate ventilation.
(d) Shock and Vibration
Although the transmitter is designed to be
relatively resistant to shock and vibration, an
installation site should be selected where this is
kept to a minimum.
(e) Installation of Explosion-protected Transmitters
An explosion-protected transmitters is
certied for installation in a hazardous area
containing specic gas types. See subsection
2.8 “Installation of an Explosion-Protected

2.5 Pressure Connection
WARNING
• Never loosen the process connector bolts
when an instrument is installed in a process.
The device is under pressure, and a loss of
seal can result in a sudden and uncontrolled
release of process uid.
• When draining toxic process uids that have
condensed inside the pressure detector,
take appropriate steps to prevent the contact
of such uids with the skin or eyes and the
inhalation of vapors from these uids.
The following precautions must be observed
in order to safely operate the transmitter under
pressure.
(a) Make sure that all the process connector bolts
are tightened rmly.
(b) Make sure that there are no leaks in the impulse
piping.
(c) Never apply a pressure higher than the
specied maximum working pressure.
2.6 Restrictions on Use of Radio Transceivers
IMPORTANT
Although the transmitter has been designed to
resist high frequency electrical noise, if a radio
transceiver is used near the transmitter or its
external wiring, the transmitter may be affected
by high frequency noise pickup. To test this, start
out from a distance of several meters and slowly
approach the transmitter with the transceiver
while observing the measurement loop for noise
effects. Thereafter use the transceiver outside
the range where the noise effects were rst
observed.
2.7 Insulation Resistance and Dielectric Strength Test
Since the transmitter has undergone insulation
resistance and dielectric strength tests at the factory
before shipment, normally these tests are not
required. If the need arises to conduct these tests,
heed the following:
(a) Do not perform such tests more frequently than
is absolutely necessary. Even test voltages that
do not cause visible damage to the insulation
may degrade the insulation and reduce safety
margins.
(b) Never apply a voltage exceeding 500 V DC
(100 V DC with an internal lightning protector)
for the insulation resistance test, nor a voltage
exceeding 500 V AC (100 V AC with an internal
lightning protector) for the dielectric strength
test.
(c) The procedure for conducting these tests is as
follows:
• Insulation Resistance Test
1) Remove the battery pack. See subsection 9.4.5
for details on how to remove it.
2) Short-circuit the battery connection terminals in
the terminal box.
3) Turn OFF the insulation tester. Then connect
the insulation tester plus (+) lead wire to the
shorted battery connection terminals and the
minus (–) leadwire to the grounding terminal.
4) Turn ON the insulation tester power and
measure the insulation resistance. The voltage
should be applied as briey as possible to verify
that the insulation resistance is at least 20 MΩ.
5) After completing the test and being very careful
not to touch exposed conductors disconnect the
insulation tester and connect a 100 kΩ resistor
between the grounding terminal and the shortcircuiting battery connection terminals. Leave
this resistor connected at least one second to
discharge any static potential. Do not touch the
terminals while it is discharging.

NOTE
When storing the instrument with a battery
pack, it is recommended to put the instrument in
Deep Sleep mode to conserve the batteries. For
details on how to switch to Deep Sleep mode,
refer to subsection 8.3.12 “Switching to Deep
Sleep Mode”.
• Dielectric Strength Test
1) Remove the battery pack. See subsection 9.4.5
for details on how to remove it.
2) Short-circuit the battery connection terminals in
the terminal box.
3) Turn OFF the dielectric strength tester. Then
connect the tester between the shorted battery
connection terminals and the grounding
terminal. Be sure to connect the grounding lead
of the dielectric strength tester to the ground
terminal.
4) Set the current limit on the dielectric strength
tester to 0.1 mA, then turn ON the power and
gradually increase the test voltage from ‘0’ to
the specied voltage.
5) When the specied voltage is reached, hold it
for one minute.
6) After completing this test, slowly decrease the
voltage to avoid any voltage surges.
NOTE
When storing the instrument with a battery
pack, it is recommended to put the instrument in
Deep Sleep mode to conserve the batteries. For
details on how to switch to Deep Sleep mode,
refer to subsection 8.3.12 “Switching to Deep

4.3 Rotating Transmitter Section
WARNING
Intrinsic safe type transmitters must be, as a rule,
do not rotate transmitter section if it is powered.
In case you need to rotate when the transmitter
is powered, using gas detector and conrm no
existence of explosive gas before rotating.
The transmitter section can be rotated
approximately 360° (180° to either direction or
360° to one direction from the original position at
shipment, depending on the conguration of the
instrument.) It can be xed at any angle within
above range.
1) Remove the ve setscrews that fasten the
transmitter section and capsule assembly,
using the Allen wrench.
2) Rotate the transmitter section slowly and stop
it at designated position. For the EJX530B
whose capsule code is A, B or C, the pipe of
the atmospheric opening may interfere with
the stopper and disturb further rotation. In that
case, screw off the pipe rst, rotate the housing,
and then screw in the pipe by hand again.
3) Tighten the ve setscrews to a torque of 1.5
N·m.

5. Installing Impulse Piping
5-1
5.1 Impulse Piping Installation Precautions
The impulse piping that connects the process
outputs to the transmitter must convey the process
pressure accurately. If, for example, gas collects in
a liquidlled impulse line, or the drain for a gas-lled
impulse line becomes plugged, it will not convey the
pressure accurately. Since this will cause errors in
the measurement output, select the proper piping
method for the process uid (gas, liquid, or steam).
Pay careful attention to the following points when
routing the impulse piping and connecting the
impulse piping to a transmitter.
5.1.1 Connecting Impulse Piping to a Transmitter
IMPORTANT
The transmitter can be installed in horizontal
impulse piping conguration, tilting the
transmitter's position up to 90°. When tilting,
observe that the pipe (for Model EJX530B
with measurement span code A, B, and C) is
positioned horizontal downwards, or any place
between them, as shown in Figure 5.1 The
zero-adjustment screw must be positioned
downwards for all the models.
5.1.2 Routing the Impulse Piping
(1) Process Pressure Tap Angles
If condensate, gas, sediment or other extraneous
material in the process piping gets into the impulse
piping, pressure measurement errors may result. To
prevent such problems, the process pressure taps
must be angled as shown in gure 5.2 according to
the kind of uid being measured.
NOTE
• If the process uid is a gas, the taps must be
vertical or within 45° either side of vertical.
• If the process uid is a liquid, the taps must
be horizontal or below horizontal, but not
more than 45° below horizontal.
• If the process uid is steam or other
condensing vapor, the taps must be
horizontal or above horizontal, but not more
than 45° above horizontal.

If the zero-adjustment screw is positioned other than
downwards after installation, rotate the housing until it is

F0501.ai
(2) Position of Process Pressure Taps and
Transmitter
If condensate (or gas) accumulates in the impulse
piping, it should be removed periodically by
opening the drain (or vent) plugs. However, this will
generate a transient disturbance in the pressure
measurement, and therefore it is necessary to
position the taps and route the impulse piping so
that any extraneous liquid or gas generated in the
leadlines returns naturally to the process piping.
• If the process uid is a gas, then as a rule the
transmitter must be located higher than the
process pressure taps.
• If the process uid is a liquid or steam, then as a
rule the transmitter must be located lower than
the process pressure taps.
IM 01C27F01-01EN
<5. Installing Impulse Piping>
5-2
(3) Impulse Piping Slope
The impulse piping must be routed with only an
upward or downward slope. Even for horizontal
routing, the impulse piping should have a slope of
at least 1/10 to prevent condensate (or gases) from
accumulating in the pipes.
(4) Preventing Freezing
If there is any risk that the process uid in the
impulse piping or transmitter could freeze, use a
steam jacket or heater to maintain the temperature
of the uid.
NOTE
After completing the connections, close the
valves on the process pressure taps (main
valves), the valves at the transmitter (stop
valves), and the impulse piping drain valves,
so that condensate, sediment, dust and other
extraneous material cannot enter the impulse
piping.

5.2 Impulse Piping Connection Examples
Figure 5.3 shows examples of typical impulse
piping connections. Before connecting the
transmitter to the process, study the transmitter
installation location, the process piping layout,
and the characteristics of the process uid
(corrosiveness, toxicity, ammability, etc.), in order
to make appropriate changes and additions to the
connection congurations.
Note the following points when referring to these
piping examples.
• If the impulse line is long, bracing or supports
should be provided to prevent vibration.
• The impulse piping material used must
be compatible with the process pressure,
temperature, and other conditions.
• A variety of process pressure tap valves (main
valves) are available according to the type
of connection (anged, screwed, welded),
construction (globe, gate, or ball valve),

6.1 Mounting Antenna and Wiring
For Amplier housing code 8 and 9, an antenna
is not attached to the transmitter. The following
provides the instructions for mounting the antenna
and installing the remote antenna and wiring using
antenna extension cable.
IMPORTANT
6-1
The antenna connector is covered with a cap
at the time of delivery. Keep the cap attached
until the installation of the antenna or antenna
cables to protect the inside connection part.
The unscrewed cap should be stored in order
to replace it immediately after the antenna or
antenna cables are removed.
CAUTION
To maintain the ultimate conditions of radiofrequency signal, protect the connectors of
antenna, extension antenna cable, and arrester
from the corrosive atmosphere by the following
treatment.
1. Clean the connection to be protected.
2. Wind the butyl rubber self-bonding tape
around the connection. See the manual of
the tape about the winding.
3. To protect the butyl rubber self-bonding tape
from the environment such as ultraviolet rays
and so on, wind vinyl tape (or a vinyl type
self-bonding tape) on it.

by tightening the lower nut part. Screwing the
antenna by holding the antenna body may cause
failure such as cable disconnection. The same
manner should be taken when unscrewing the
antenna.
6.1.1 Mounting the antenna
Screw the provided antenna into the antenna
connector of the transmitter. The antenna may
be sold as available accessories and supplied
separately.
1. Unscrew the antenna connector cap on the

6.1.2 Mounting External Antenna and Wiring Antenna Extension Cable
6.1.2.1 Mounting of External Antenna
Mount the external antenna at the proper location
according to the wireless environment described
in 2.4 Selecting the Installation Location. The
mounting to the pipe such as 50 mm (2-inch) pipe
needs to secure the enough strength to endure a
strong wind, vibration and so on. The antenna must
be mounted vertically.
Fixing of External Antenna
Fix an external antenna appropriately using the
bracket provided as the external antenna option to
50 mm (2-inch) pipe.

1. Fix the bracket by U-bolt and nut to 50 mm (2inch) pipe.
2. Fix the antenna extension cable to the bracket
1 using the provided nut with a torque of 6 to 7
N∙m as shown in the Figure 6.3 above. Use the
nut which is attached to the antenna extension
cable.
3. Screw the antenna into the antenna connector
of the antenna extension cable on the bracket
1.
Tighten the antenna connector with a torque of
2 to 3 N∙m.
4. Protect the connection as necessary. For
details of the protection, see “6.1 Mounting
Antenna and Wiring.”
6.1.2.2 Wiring of Antenna Extension Cable
1. Use the provided antenna extension cable
to connect the antenna connector with the
external antenna. Tighten the connector of the
antenna extension cable with a torque of 2
to 3 N∙m. The minimum bending radius while
checking the wiring position should be more
than 200 mm.
2. When using two extension cables, the provided
arrester should be inserted between these
cables.
3. Before the wiring work, conrm the polarities
(male/female) of the connectors of antenna,
extension antenna cable, and arrester. Tighten
the connector of the antenna extension cable
with a torque of 2 to 3 N∙m.
4. Protect the connectors of antenna, extension
antenna cable, and arrester as necessary. See
“6.1 Mounting Antenna and Wiring.”
5. Fix the extension antenna cable to the
appropriate structure to protect the cable from
the vibration, wind, and so on. The minimum
bending radius for xing in the state maintained
for a long period should be more than 80 mm.

6.2 Grounding
When using the antenna extension cable with an
arrestor, Class C grounding with the grounding
resistance of 10 Ω is required. Always ground the
transmitter case in accordance with national and
local electrical codes. The most effective transmitter
case grounding method is a direct connection to
earth ground with minimal impedance.
CAUTION
Grounding is recommended for safe operation.
