Note 3. Operation
• WARNING:
AFTER DE-ENERGIZING, DELAY 5
MINUTES BEFORE OPENING.
• WARNING:
WHEN THE AMBIENT TEMP.≥65°C, USE
HEAT-RESISTING CABLE AND CABLE
GLAND ≥90°C.
• Take care not to generate mechanical
sparking when accessing to the instrument
and peripheral devices in a hazardous
location.
• Electrostatic charge may cause an explosion
hazard. Avoid any actions that cause the
generation of electrostatic charge, such as
rubbing with a dry cloth on coating face of the
product.

2.11 Pressure Equipment
Directive (PED)
(1) General
• EJX/EJA-E Series pressure transmitters are
categorized as piping under the pressure
accessories section of directive 2014/68/EU,
which corresponds to Article 4, Paragraph 3 of
PED, denoted as Sound Engineering Practice
(SEP).
• EJX110A-
MS, EJX110A-
HS,
EJX110A-
VS, EJ
130
, EJ
440
, and
EJA110E with /HG 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 4, Paragraph 3 of PED, denoted as
Sound Engineering Practice (SEP).
• Models with /PE3
Module: H
Type of Equipment: Pressure Accessory-Vessel
Type of fluid: Liquid and Gas
Group of fluid: 1 and 2
