2.8.4 IECEx Certification
Caution for IECEx Intrinsically safe type.
Note 1. Model EJX Series pressure transmitters
with optional code /SS27 for potentially
explosive atmospheres:
• Applicable standards:
IEC 60079-0, IEC 60079-11, IEC 60079-28
• Certificate number: IECEx KEM10.0074X
• Specific Ex marking: Ex ia op is IIC T4 Ga
• Ambient temperature: –50°C ≤ Ta ≤ +70°C
• Process temperature: –50°C ≤ Tp ≤ +120°C
• Enclosure: IP66/IP67 in accordance with
only IEC 60529
• Battery: Battery pack: F9915MA or F9915NS
(YOKOGAWA)
• Dielectric strength:
500 V AC, r.m.s.,
1 min
Battery
connection
terminals
to Enclosure
• RF source: ≤ 20 mW
• Optical source: ≤ 35 mW
Note 2. Specific condition of use
When the equipment is mounted in an area
where the use of EPL Ga equipment is required,
it shall be installed in such a way that, even in
the event of rare incidents, an ignition source
due to impact and/or friction sparks is excluded.
Precaution shall be taken to minimize the risk
from electrostatic discharges or propagating brush
discharges on the non-metallic parts (excluding
glass parts) or coated parts of the equipment.
Note 3. Installation and erection
See the control drawing.
If the equipment is mounted in an area where
explosive atmospheres may be present, it must
be installed in such a way that the risk from
electrostatic discharges.
Note 4. Use and setting-up (operation)
The battery pack may be replaced in a hazardous
area. The battery pack has surface resistivity
greater than 1G ohm and must be properly installed
in the enclosure of the transmitter. Care must be
taken during transportation to and from the point of
installation to prevent electrostatic charge build-up.
Use only F9915MA or F9915NS for the battery pack.
Precaution shall be taken to minimize the risk
from electrostatic discharge when replacing the
battery pack in a hazardous area.
Use only TL-5930/S or SL-2780/S (TADIRAN)
or SB-D02 (Vitzrocell) for the cells. The cells
must be replaced in a non-hazardous area.
Note 5. Maintenance and repair
WARNING
A modification of the equipment would no longer
comply with the construction described in the
certificate documentation.
Only personnel authorized by Yokogawa Electric
Corporation can repair the equipment.
Only Electrical connection code: J is applicable.
