2.2 Unpacking
Keep the transmitter in its original packaging to
prevent it from being damaged during shipment.
Do not unpack the transmitter until it reaches the
installation site.
2.3 Storage
The following precautions must be observed when
storing the instrument, especially for a long period.
(a) Select a storage area which meets the following
conditions:
• It is not exposed to rain or subject to water
seepage/leaks.
• Vibration and shock are kept to a minimum.
• It has an ambient temperature and relative
humidity within the following ranges.
Ambient temperature:
–40* to 85°C without integral indicator
–30* to 80°C with integral indicator
*–15°Cwhen/HEisspecied.
Relative humidity:
0% to 100% R.H.
Preferred temperature and humidity:
approx. 25°C and 65% R.H.
(b) When storing the transmitter, repack it carefully
in the packaging that it was originally shipped
with.
(c) If the transmitter has been used, thoroughly
cleanthechambersinsidethecoveranges,so
thatthereisnoprocessuidremaininginside.
Before placing it in storage, also make sure that
the pressure-detector is securely connected to
the transmitter section.

<2. Handling Cautions> 2-2
IM 01C25B01-01E
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) AmbientTemperature
Avoid locations subject to wide temperature
variationsorasignicanttemperaturegradient.
If the location is exposed to radiant heat from
plant equipment, provide adequate thermal
insulation and/or ventilation.
(b) AmbientAtmosphere
Do not install the transmitter in a corrosive
atmosphere. If this cannot be avoided, there
must be adequate ventilation as well as
measures to prevent the leaking of rain water
and the presence of standing water in the
conduits.
(c) 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.
(d) Installation of Explosion-protectedTransmitters
An explosion-protected transmitters is
certiedforinstallationinahazardousarea
containingspecicgastypes.Seesubsection
2.9 “Installation of an Explosion-Protected
Transmitters.”
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
speciedmaximumworkingpressure.
2.6 WaterproongofCable
Conduit Connections
Apply a non-hardening sealant to the threads
to waterproof the transmitter cable conduit
connections.(Seegure6.8,6.9and6.10.)
2.7 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.
2.8 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.

<2. Handling Cautions> 2-3
IM 01C25B01-01E
(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 VAC (100 VAC with an internal
lightning protector) for the dielectric strength
test.
(c) Before conducting these tests, disconnect
all signal lines from the transmitter terminals.
The procedure for conducting these tests is as
follows:
• Insulation Resistance Test
1) Short-circuit the + and – SUPPLY terminals in
the terminal box.
2) Turn OFF the insulation tester. Then connect
the insulation tester plus (+) lead wire to the
shorted SUPPLY terminals and the minus (–)
leadwire to the grounding terminal.
3) Turn ON the insulation tester power and
measure the insulation resistance.The voltage
shouldbeappliedasbrieyaspossibletoverify
thattheinsulationresistanceisatleast20MΩ.
4) 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 short-
circuiting SUPPLY terminals. Leave this resistor
connected at least one second to discharge any
static potential. Do not touch the terminals while
it is discharging.
• Dielectric Strength Test
1) Short-circuit the + and – SUPPLY terminals in
the terminal box.
2) Turn OFF the dielectric strength tester. Then
connect the tester between the shorted
SUPPLY terminals and the grounding terminal.
Be sure to connect the grounding lead of the
dielectric strength tester to the ground terminal.
3) Set the current limit on the dielectric strength
tester to 10 mA, then turn ON the power and
gradually increase the test voltage from ‘0’to
thespeciedvoltage.
4)Whenthespeciedvoltageisreached,holdit
for one minute.
5) After completing this test, slowly decrease the
voltage to avoid any voltage surges.

To meet EMC regulations, Yokogawa
recommends that customers run signal
wiring through metal conduits or use shielded
twisted-pair cabling when installing EJX series
transmitters in a plant.
2.11 Pressure Equipment
Directive (PED)
(1) General
• EJX Series pressure transmitters are
categorized as piping under the pressure
accessories section of directive 97/23/EC,
which corresponds toArticle 3, Paragraph 3 of
PED, denoted as Sound Engineering Practice
(SEP).

• EJX110A-MS, EJX110A-HS,
EJX110A-VS, EJX130A, EJX440A,
EJX510A-D, and EJX530A-D can be used
above 200 bar and therefore considered as
a part of a pressure retaining vessel where
category III, Module H applies.These models
with option code /PE3 conform to that category.

(3) Operation
CAUTION
• Thetemperatureandpressureofuidshould
be maintained at levels that are consistent
with normal operating conditions.
• The ambient temperature should be
maintained at a level that is consistent with
normal operating conditions.
• Please take care to prevent water hammer
and the like from inducing excessive
pressures in pipes and valves. If phenomena
are likely, install a safety valve or take
some other appropriate measure to prevent
pressure from exceeding PS.
• Take appropriate measures at the device or
system level to protect transmitters if they
are to be operated near an external heat
source.
2.12 Low Voltage Directive
Applicable standard: EN61010-1
(1) Pollution Degree 2
"Pollution degree" describes the degree to
which a solid, liquid, or gas which deteriorates
dielectric strength or surface resistivity is
adhering. " 2 " applies to normal indoor
atmosphere. Normally, only non-conductive
pollution occurs. Occasionally, however,
temporary conductivity caused by condensation
must be expected.
(2) Installation Category I
"Overvoltage category (Installation category)"
describesanumberwhichdenesatransient
overvoltage condition. It implies the regulation
for impulse withstand voltage. " I " applies to
electrical equipment which is supplied from the
circuit when appropriate transient overvoltage
control means (interfaces) are provided.
