2. HANDLING CAUTIONS
2. HANDLING CAUTIONS
This chapter describes important cautions regarding
how to handle the transmitter. Read carefully before
using the transmitter.
The EJA-A Series pressure transmitters are thoroughly
tested at the factory before shipment. When the
transmitter is delivered, visually check them to make
sure that no damage occurred during shipment.
Also check that all transmitter mounting hardware
shown in Figure 2.1 is included. If the transmitter was
ordered without the mounting bracket or without the
process connector, the transmitter mounting hardware
is not included. After checking the transmitter, repack
it in the way it was delivered until installation.

: Refer to USER'S MANUAL
Figure 2.2 Name Plate
2.2 Unpacking
When moving the transmitter to the installation site,
keep it in its original packaging. Then, unpack the
transmitter there to avoid damage on the way.
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 water.
• It suffers minimum vibration and shock.
• 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
Relative humidity:
5% to 100% R.H. (at 40°C)
Preferred temperature and humidity:
approx. 25°C and 65% R.H.
(b) When storing the transmitter, repack it as nearly as
possible to the way it was packed when delivered
from the factory.
(c) If storing a transmitter that has been used, thor-
oughly clean the chambers inside the cover flanges,
so that no measured fluid remains in it. Also make
sure before storing that the pressure-detector and
transmitter section are securely mounted.
2.4 Selecting the Installation
Location
The transmitter is designed to withstand severe
environmental conditions. However, to ensure stable
and accurate operation for years, observe the following
precautions when selecting an installation location.
(a) Ambient Temperature
Avoid locations subject to wide temperature
variations or a significant temperature gradient. If
the location is exposed to radiant heat from plant
equipments, provide adequate thermal insulation
and/or ventilation.
(b) Ambient Atmosphere
Avoid installing the transmitter in a corrosive
atmosphere. If the transmitter must be installed in a
corrosive atmosphere, there must be adequate
ventilation as well as measures to prevent intrusion
or stagnation of rain water in conduits.

IM 01C21C01-01E
2-2
2. HANDLING CAUTIONS
(c) Shock and Vibration
Select an installation site suffering minimum shock
and vibration (although the transmitter is designed
to be relatively resistant to shock and vibration).
(d) Installation of Explosion-protected Transmitters
Explosion-protected transmitters can be installed in
hazardous areas according to the types of gases for
which they are certified. See Subsection 2.9
“Installation of Explosion Protected Type Transmit-
ters.”
2.5 Pressure Connection
WARNING
• Instrument installed in the process is under
pressure. Never loosen the process connector
bolts to avoid the dangerous spouting of
process fluid.
• During draining condensate from the pressure-
detector section, take appropriate care to avoid
contact with the skin, eyes or body, or inhala-
tion of vapors, if the accumulated process fluid
may be toxic or otherwise harmful.
The following precautions must be observed in order to
safely operate the transmitter under pressure.
(a) Make sure that the two process connector bolts are
tightened firmly.
(b) Make sure that there are no leaks in the impulse
piping.
(c) Never apply a pressure higher than the specified
maximum working pressure.
2.6 Waterproofing of Cable
Conduit Connections
Apply a non-hardening sealant to the threads to
waterproof the transmitter cable conduit connections.
(See Figure 6.4.2a, 6.4.2b and 6.4.2c.)
2.7 Restrictions on Use of Radio
Transceiver
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 for such
effects, bring the transceiver in use slowly from a
distance of several meters from the transmitter,
and observe the measurement loop for noise
effects. Thereafter, always use the transceiver
outside the area affected by noise.
2.8 Insulation Resistance and
Dielectric Strength Test
Since the transmitter has undergone insulation resis-
tance and dielectric strength tests at the factory before
shipment, normally these tests are not required.
However, if required, observe the following precau-
tions in the test procedures.
(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) Before conducting these tests, disconnect all signal
lines from the transmitter terminals. Perform the
tests in the following procedure:
• 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 short as possible to verify that the insula-
tion resistance is at least 20 M1.
4) After completing the test and being very careful not
to touch exposed conductors disconnect the
insulation tester and connect a 100 k1resistor
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.

IM 01C21C01-01E
2-3
2. HANDLING CAUTIONS
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 specified
voltage.
4) When the specified voltage is reached, hold it for
one minute.
5) After completing this test, slowly decrease the
voltage to avoid any voltage surges.
2.9 Installation of Explosion
Protected Type
In this section, further requirements and differences
and for explosionproof type instrument are described.
For explosionproof type instrument, the description in
this chapter is prior to other description in this users
manual.
For the intrinsically safe equipment and explosionproof
equipment, in case the instrument is not restored to its
original condition after any repair or modification
undertaken by the customer, intrinsically safe construc-
tion or explosionproof construction is damaged and
may cause dangerous condition. Please contact
Yokogawa for any repair or modification required to
the instrument.

applies to normal indoor atmosphere. Normally,
only non-conductive pollution occurs. Occasionally,
however, temporary conductivity caused by
condenstaion must be expected.
(2) Installation Category I
"Overvoltage category(Installation category)"
describes a number which defines a transient
overvoltage condition. It implies the regulattion for
impulse withstand voltage. " I " applies to electrical
equipment which is supplied from the circuit when
appropriate transient overvoltage control means
(interfaces) are provided.
