• 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.

*1: PS is maximum pressure for vessel itself based on
Pressure Equipment Directive 97/23/EC. Refer to
GeneralSpecicationformaximumworkingpressureofa
transmitter.
*2: Referred to Table 1 covered by ANNEX II of EC Directive
on Pressure Equipment Directive 97/23/EC
(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.
