(3) Operation
CAUTION
• The temperature and pressure of fluid 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.
2.11 Low Voltage Directive
Applicable standard:
EN61010-1, EN61010-2-030
(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
(Anticipated transient overvoltage 330 V)
"Overvoltage category (Installation category)"
describes a number which defines 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.
(3) Indoor/Outdoor use
It can be used in indoors and outdoors.
(4) Altitude of installation site
Max. 2,000 m above sea level
