Instructions Specific To Hazardous Area Installations; Instructions - Special Condition For Safe Use - GE Baker Hughes Masoneilan 4411 Instruction Manual

Instructions Specific to
Hazardous Area Installations
(Reference European ATEX Directive 2014/34/EU,
Annex II, 1.0.6)
The following instructions apply to equipment covered by
certificate numbers SIRA 01ATEX2224X & SIRA 01ATEX1223
1. The Model 4411 may be installed as intrinsically safe or
flameproof:
• Zone 0 or 20 installations require the equipment to be
installed as intrinsically safe via suitable associated
apparatus.
• Zone 1 or 21 installations require the equipment to be
installed as intrinsically safe or flameproof; if installed
as flameproof, associated apparatus is not required,
but there are more onerous requirements for cable
entry – refer to EN60079-0.
• Zone 2 or 22 installations may be intrinsically safe or
flameproof.
• It is recommended that the installer indicates on the
equipment which certification code applies.
2. The equipment should not be used outside the stated
ambient temperature range.
3. The equipment has not been assessed as a safety-related
device (as referred to by Directive 2014/34/EU Annex II,
clause 1.5).
4. Installation and maintenance of this equipment shall be
carried out by suitably-trained personnel in accordance
with the applicable codes of practice (EN 60079-14 and
EN 60079-17 within Europe).
5. Repair of this equipment shall be carried out by the
manufacturer or in accordance with the applicable code
of practice (IEC 60079-19).
6. When installing the equipment as flameproof cable gland
(M20 parallel thread) or a conduit (1/2" NPT tapered
thread), the installer should verify the thread form and
ensure that the appropriate matching thread is used. The
pneumatic connections are not flameproof entries.
7. The certification of this equipment relies on the following
materials used in its construction:
Enclosure: aluminium alloy and zinc alloy
O-ring: nitrile rubber
Encapsulant: polyurethane
If the equipment is likely to come into contact with aggressive
substances, then it is the responsibility of the user to take
suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection is not
compromised.
• Aggressive substances: e.g. acidic liquids or gases that
may attack metals, or solvents that may affect polymeric
materials.
8 | BHGE
• Suitable precautions: e.g. regular checks as part of
routine inspections or establishing from the material's
data sheet that it is resistant to specific chemicals.
• Not to be used with pure oxygen or oxygen enriched
media as the process fluid.
Consult the supplier for approval certificates.
8. Only approved cable glands are to be used which must
maintain an Ingress Protection of IP66.
9. Unused entry port hole must be blanked off using suitably
approved blanking plug conforming to the hazardous
area certification rating applicable.
Instructions – Special Condition
for Safe Use
For Certificate Number Sira 01ATEX1223 – (Ex d) None.
For Certificate Number Sira 01ATEX2224X – (Ex ia)
1. For operation reasons, it may be necessary to connect the
screen of the cable to the enclosure of the equipment in
the hazardous area. If this is the case, then the equipment
shall be installed in accordance with EN 60078-14:2014
(specifically clause 16.2.2.3 and 16.2.4), typically using a
galvanically-isolated interface with no other connection
to Earth apart from via the enclosure of the equipment.
2. The enclosure is made from light metal which could cause
ignition due to impact and friction. This shall be taken
into consideration when the apparatus is installed in
location that specifically requires equipment protection
level Ga.
3. Under certain extreme circumstances, the non-metallic
parts incorporated in the enclosure of this equipment
may generate an ignition-capable level of electrostatic
charge. Therefore, when it is used for applications that
specially require equipment protection level Ga, the
equipment shall not be installed in a location where the
external conditions are conductive to the build-up of
electrostatic charge on such surfaces. Additionally, the
equipment shall only be cleaned with a damp cloth.
4. The option for the air vented from the enclosure to
be re-circulated and introduced back into the process
stream shall not be used when the equipment is
installed in locations that specifically require equipment
protection level Ga for group II category 1G or 1D for
group III category 1D equipment.
