PMA Ex-System
Operating and Assembly
Instructions
for ATEX-approved PMA
IP66 components
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 IP66 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-IP66 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
replacement of ATEX-approved parts.
These operating and assembly instructions include important
information for service and maintenance and should therefore be
retained.
5. Assembly
To ensure the discharge of electrical currents and thus to ensure
antistatic 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 IP66 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.
