Safety instructions for the P1S cylinder with accessories
Supplementary safety instructions for installation of
ATEX certified P1S cylinders.
The safety instructions in this document are valid for the ATEX certified
P1S cylinders, bore 32 - 125mm, as per below with reference to the order
code key in the product catalogue.
P1S-C***MS-****-EXNN
P1S-D***MS-****-EXNN
P1S-E***MS-****-EXNN
P1S-F***MS-****-EXNN
P1S-L***MS-****-EXNN
All strokes in the range 25 - 1000mm
Serious, even fatal, damage or injury may be caused by the hot
moving parts of the P1S cylinders in the presence of explosive gas
mixtures and concentrations of dust.
All installation, connection, commissioning, servicing and repair
work on P1S cylinders must be carried out by qualified personnel
taking account of the following
• These instructions
• Markings on the cylinder
• All other planning documents, commissioning instructions and
connection diagrams associated with the application.
• Provisions and requirements specific to the application
• National/international regulations (explosion protection, safety and
accident prevention)
Real life applications
P1S cylinders are designed to provide linear movement in industrial
applications, and should only be used in accordance with the
instructions in the technical specifications in the catalogue, and
within the operating range indicated on the rating plate.
The cylinders meet the applicable standards and requirements of
directive 94/9/EC (ATEX)
The cylinders must not be used underground in mines susceptible to
firedamp and/or flammable dusts. The cylinders are intended for use
in areas in which explosive atmospheres caused by gases, vapours
or mists of flammable liquids, or air/dust mixtures may be expected
to occur during normal use (infrequently)
Checklist
Before using the cylinders in an Ex-area, you should check the
following:
Do the specifications of the P1S cylinder match the Ex-classification
of the area of use in accordance with directive 94/9/EC (previously
ATEX 100a)
• Equipment group
• Ex-equipment category
• Ex-zone
• Temperature class
• Max. surface temperature
1. When installing the P1S cylinder, is it certain that there is no
potentially explosive atmosphere, oil, acids, gases, vapours or
radiation?
2. Is the ambient temperature as specified in the technical data in
the catalogue at all times?
3. Is it certain that the P1S cylinder is adequately ventilated and that
no forbidden additional heat is added?
4. Are all the driven mechanical components ATEX certified?
5. Check that the P1S cylinder is safely earthed.
6. Check that the P1S cylinder is supplied with compressed air.
Explosive gas mixtures must not be used for driving the cylinder.
7. Check that the P1S cylinder is not equipped with a metal scraper
ring (special version).
Installation requirements in Ex-areas
• The temperature of the supply air must not exceed the ambient
temperature.
• The P1S cylinder may be installed in any position.
• The P1S cylinder must not be installed where there is a risk of
mechanical contact with any surrounding part or component.
• An air treatment unit must be attached to the inlet of the P1S
cylinder.
• The P1S cylinder must be connected to earth at all times, through
its support, a metallic tube or separate conductor.
• The outlet of the P1S cylinder must not be open within an
Ex-area, but must be connected to the silencer or, preferably,
piped and released outside the Ex-area.
• The P1S cylinder may only drive units that are ATEX certified.
• Ensure that the P1S cylinder is not exposed to forces greater than
those permitted in accordance with the catalogue
• The P1S cylinder must be supplied with compressed air.
Explosive gas mixtures must not be used
• P1S cylinders with metal scraper rings must not be used in
Ex-areas
Inspecting cylinders during operation
The P1S cylinder must be kept clean on the outside, and a layer of
dust/dirt thicker than 1 mm must never be allowed to form.
Inspect and verify that the cylinder, with attachments, compressed air
fittings, hoses, tubes, etc. meet the standards of "safe" installation.
Spare parts
Only spare parts, kits etc. supplied by Parker Hannifin may be used
for repair and maintenance of the P1S cylinders.
Marking of ATEX certified P1S cylinders
The ATEX certified P1S cylinders, bore 32 - 125mm, as per below with
reference to the order code key in the product catalogue have an ATEX
certification marking as shown further below.
P1S-C***MS-****-EXNN
P1S-D***MS-****-EXNN
P1S-E***MS-****-EXNN
P1S-F***MS-****-EXNN
P1S-L***MS-****-EXNN
All strokes in the range 25 - 1000mm
II 2GD c T4 120 °C
Communauté Européenne = EU
CE on the product shows that Parker Hannifin products meet
one or more EU directives
Ex means that this product is intended for use in potentially
explosive atmospheres
II
Stands for the equipment group (I = mines and II = other
hazardous areas)
2GD
Stands for equipment category 2G means the equipment
can be used in zones 1 and 2 where there is a risk involving
gases, vapours or mists of combustible liquids and 2D in
zones 21 and 22 where there is a risk involving dusts. 2GD
Means the equipment can be used in zones 1, 2, 21 and 22.
c
Safe design (prEN 13463-5)
T4
If equipment is in temperature class T4, the maximum
surface temperature must not exceed 135 °C. (To guarantee
this, the product has been tested to ensure that the maximum
is 130 °C. This provides a safety margin of 5 °K.)
120 °C Maximum permitted surface temperature on P1D-S cylinder
in atmospheres containing potentially explosive dusts.
