PMA Ex-System
Operating and Assembly
Instructions
for ATEX-approved PMA components
with female thread
In accordance with: EN 1127-1, EN 60079-0, EN 60079-7, EN 60079-31
1.
Intended Use
This is an operating manual for electrically discharging cable protection
systems consisting of conduits, connectors and accessories. The
products are made of discharging material to prevent the buildup
of electrostatic charges. These products are therefore not suited as
electrical insulation materials.
These cable protection systems are intended to protect electrical
cables and wires from damage or wear due to mechanical effects as
well as weathering effects (UV radiation).
Use of these products as medium-conducting lines (for liquids, gases,
bulk material) is not intended by the manufacturer.
2.
Conformity Marking
The Ex conformity marking for the electrically discharging products is
as follows:
CE 1258
II 2G Ex eb IIC II 2D Ex tb IIIC IP68 SEV 05 ATEX 105.
This number is given on the packaging label and on the actual
product and enables clear identification of the products which are
made of discharging material.
3.
Area of Application
The products constitute an equipment group II category 2G device in
accordance with Directive 94/9/EC (ATEX 95) Appendix I which may
be implemented in zones 1 / 2 as well as in gas groups IIA, IIB and IIC
which are subject to explosion risk due to combustible substances, in
accordance with Directive 99/92/EC (ATEX 137). The requirements in
accordance with EN 60079-14 shall be adhered to on use/installation.

MONTANL EX-EIR 07.13
The products constitute an equipment group II category 2D device in
accordance with Directive 94/9/EC (ATEX 95) Appendix I which may
be implemented in zones 21 / 22 with ex plosive air/dust mixtures in
accordance with Directive 99/92/EC (ATEX 137). The requirements in
accordance with EN 60079-14 shall be adhered to on use/installation.
4.
Operation, Service, Maintenance
The defined ambient and operating temperature range is –20 °C to
+85 °C (temperature range for electrical equipment in accordance with
EN 60079-0).
A visual examination of the cable protection system shall be performed
in periodic maintenance of systems and components, but no later than
every 5 years. In the event of visible damage (holes, cracks, signs of
heavy wear) to conduits, fittings or accessories, the damaged parts
shall be replaced. (In the event of apparent mechanical damage, it shall
be ensured that no incorrect handling takes place.)
Only ATEX-approved original PMA parts shall be used for the replace-
ment of ATEX-approved parts.
These operating and assembly instructions include important informa-
tion for service and maintenance and should therefore be retained.
5.
Assembly
To ensure the discharge of electrical currents and thus to ensure anti-
static behavior, ATEX-approved PMA conduits shall be used exclusively
in combination with special PMA connectors and accessories which
are also ATEX-approved. These connectors and accessories (seals,
fasteners) are also made of discharging material and are designated
with the conformity marking.
The ATEX-approved connectors or accessories shall always be in direct
contact with a metallic surface (ground). No insulating materials (e.g.
adhesives) and no components which are not ATEX-approved shall be
used between the discharging plastic parts or between plastic parts
and metal surfaces.
6.
Installation of IP68 Safety System (pat.)
The IP protection level can only be ensured with exact adherence to the
specifications and steps as given in the assembly instructions. Fittings
for conduit sizes NW36 and NW48 require the installation of two fit both
locking clips.
Safety remarks:
On the thread/connection side appropriate, conductive sealants must
be used for ingress protection ratings IP67 or IP68 (see picture no. 4).
For non-conductive sealants additional earthing measures has to be
taken in account.
