Note 4. Maintenance and Repair
WARNING
The instrument modification or parts replacement
by other than an authorized Representative of
Yokogawa Electric Corporation is prohibited and
will void IECEx Intrinsically safe Certification.
Note 5. Battery Pack
• Use only YOKOGAWA battery pack
F9915MA or F9915NS.
Note 6. Special conditions for Safe Use
• In case of the aluminum enclosure, if the
Transmitter is mounted in an area where the
use of EPL Ga apparatus is required, it must
be installed such, that, even in the event rare
incidents, ingition source due to impact and
friction sparks are excluded.
• For application in an area where the use of
EPL Ga apparatus is required, electrostatic
charge on the non-metallic parts of the
Temperature Transmitter shall be avoided.
WARNING
• Potential electrostatic charging hazard -
secure distance of 100mm from antenna.
• Take care not to generate mechanical
sparking when access to the instrument and
peripheral devices in a hazardous location.
2.8 EMC Conformity Standards
EN61326-1 Class A, Table 2 (For use in
industrial locations), EN61326-2-3
CAUTION
This instrument is a Class A product, and it is
designed for use in the industrial environment.
Please use this instrument in the industrial
environment only.
WARNING
The potential for discharging static electricity
should be minimized in mounting this transmitter.
For example, do not generate static electricity
as the surface of a battery pack or housing is
rubbed with cloth.
2.9 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.
