*1: PS is maximum allowable pressure for vessel itself.
*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 fl uid should be
applied under the normal operating condition.
• The ambient temperature should be applied under
the normal operating condition.
• Please pay attention to prevent the excessive
pressure like water hammer, etc. When water
hammer is to be occurred, please take measures
to prevent the pressure from exceeding PS by
setting the safety valve, etc. at the system and the
like.
• When external fi re is to be occurred, please take
safety measures at the device or system not to
infl uence the transmitters.
2.7 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 defi 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.
