Safety instructions for the P1D-S cylinder with accessories
Supplementary safety instructions for P1D-S cylinders installed in Ex-areas
Serious, even fatal, damage or injury may be caused by the hot moving
parts of the P1D cylinders in the presence of explosive gas mixtures and
concentrations of dust.
All installation, connection, commissioning, servicing and repair
work on P1D 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 con-
nection diagrams associated with the application.
• Provisions and requirements specific to the application
• National/international regulations (explosion protection, safety and
accident prevention)
Real life applications
P1D cylinders are designed to provide linear movement in industrial
applications, and should only be used in accordance with the in-
structions 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 fol-
lowing:
Do the specifications of the P1D-S cylinder match the Ex-classifica-
tion of the area of use in accordance with directive 94/9/EC (previ-
ously ATEX 100a)
• Equipment group
• Ex-equipment category
• Ex-zone
• Temperature class
• Max. surface temperature
1. When installing the P1D-S 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 P1D-S 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 P1D-S cylinder is safely earthed.
6. Check that the P1D-S cylinder is supplied with compressed air.
Explosive gas mixtures must not be used for driving the cylinder.
7. Check that the P1D-S 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 P1D-S cylinder may be installed in any position.
• An air treatment unit must be attached to the inlet of the P1D-S
cylinder.
• The P1D-S cylinder must be connected to earth at all times,
through its support, a metallic tube or separate conductor.
• The outlet of the P1D-S 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 P1D-S cylinder may only drive units that are ATEX certified.
• Ensure that the P1D-S cylinder is not exposed to forces greater
than those permitted in accordance with the catalogue
• The P1D-S cylinder must be supplied with compressed air. Explo-
sive gas mixtures must not be used
• P1D-S cylinders with metal scraper rings must not be used in Ex-
areas
Inspecting cylinders during operation
The P1D cylinder must be kept clean on the outside, and a layer of
dust/dirt thicker than 1 mm must never be allowed to form.
Strong solvents should not be used for cleaning, because they can
cause the seal (material PUR) around the piston rod to swell, poten-
tially increasing the temperature. Inspect and verify that the cylinder,
with attachments, compressed air fittings, hoses, tubes, etc. meet the
standards of "safe" installation.
Marking of cylinder P1D-S Standard
(P1D-S***MS-****)
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.

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.
