Operating and Assembly
Instructions
for ATEX-approved PMA
conduits and conduit clamps
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 SEV 05 ATEX 0105.
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-ROHR 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). Exceptions: for conduit type XESX the defined
ambient and operating temperature range is –40 °C to +85 °C, for
conduit type XESD –25 °C to +85 °C and for conduit type ESX (only for
nominal sizes 56 and 70) –45 °C to +85 °C. 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 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, fas-
teners) are also made of discharging material and are designated with
the conformity marking. The ATEX-approved connectors or accesso-
ries 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 conduits and conduit clamps
Safety instructions:
• Recommended conduit filling ratio: approx. 70%
• Recommendations for spacing between conduit clamps:
Horizontal routing: 300 mm
Vertical routing: 500 mm
• Recommended maximum bend radii for ATEX-approved
conduit types and sizes:
