Emc Conformity Standards; Pressure Equipment Directive (Ped) - YOKOGAWA DpharpEJX vigilantplant EJX110 User Manual

Note 3. Operation
• WARNING:
AFTER DE-ENERGIZING, DELAY 5 MINUTES
BEFORE OPENING.
• WARNING:
WHEN AMBIENT TEMPERATURE
USE THE HEAT-RESISTING CABLES
• Take care not to generate mechanical sparking
when accessing to the instrument and peripheral
devices in a hazardous location.
Note 4. Maintenance and Repair
• The instrument modification or parts replacement
by other than authorized representative of
Yokogawa Electric Corporation is prohibited and
will void IECEx Certification.

2.10 EMC Conformity Standards

EN61326, AS/NZS CISPR11
CAUTION
To meet EMC regulations, Yokogawa recom-
mends that customers run signal wiring through
metal conduits or use shielded twisted-pair
cabling when installing EJX series transmitters in
a plant.
2.11 Pressure Equipment
Directive (PED)
(1) General
• EJX series pressure transmitters are categorized as
pressure accessories under the vessel section of
directive 97/23/EC, which corresponds to Article 3,
Paragraph 3 of PED, denoted as Sound Engineering
Practice (SEP).
• EJX110A- M, EJX110A- H, 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.
(2) Technical Data
• Models without /PE3
Article 3, Paragraph 3 of PED, denoted as Sound
Engineering Practice (SEP).
• Models with /PE3

*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
• 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.
