CABLES IN EXPLOSIVE ATMOSPHERES
INSTALLATION INSTRUCTIONS
1. Installation should only be performed by a competent person using the correct tools. Spanners should be used for tightening. Read all instructions before beginning installation.
2. The interface between a cable entry device and its associated enclosure / cable entry will require additional sealing to achieve ingress protection (IP) ratings higher than IP54. The minimum protection level is IP54
for explosive gas atmospheres and IP6X for explosive dust atmospheres. Parallel threads (and tapered threads when using a non-threaded entry) require a CMP sealing washer or integral O-ring face seal (where
available) to maintain IP66, 67 and 68 (when applicable). It is the installer’s responsibility to ensure the IP rating is maintained at the interface. INCORPORATING EU DECLARATION OF CONFORMITY TO DIRECTIVE 2014/34/EU AND UK
3.
Note: When fitted to a threaded entry, all tapered threads will automatically provide an ingress protection rating of IP66.
A CMP earth tag should be used when it is necessary to provide an earth bond connection. CMP earth tags have been independently tested to comply with Category B rating specified in IEC 62444 (there are no STATUTORY REQUIREMENTS SI 2016 No. 1107 (AS AMENDED)
ratings stated in IEC 60079-0). Ratings are shown in the associated table. CMP earth tags slip over the cable gland or accessory entry thread from inside/outside the enclosure and must be secured with a locknut
(if fitted internally).
4. Metric entry threads comply with ISO 965-1 and ISO 965-3 with a 6g tolerance as required by IEC 60079-1:2014. The CMP standard metric thread pitch is 1.5mm for threads up to M75, and 2.0mm from M90
and above. Special thread pitches between 0.7 – 2.0mm are available on all products on request. See certificate for details of other thread types. NPT threads are in accordance with ASME B1.20.1-2013 gauging
to Cl 3.2 for external threads. For details of other thread types refer to IECEx certificate.
5. Enclosures must be strong enough to support the cable and cable gland assembly. The enclosure surface finish must be smooth and flat to facilitate sealing with an O-ring or Entry Thread Sealing Washer for the
required IP rating.
6. Enclosure walls must be sufficiently strong enough to support the cable and cable gland assembly. Enclosure entries shall be perpendicular. Any draft angles from the casting/moulding process should have a
perpendicular flat spot machined to facilitate sealing with an O-ring or Entry Thread Sealing Washer.
7. CMP Products recommends that when using the cable gland with a through-hole, the hole must be circular, free of burrs and the diameter no larger than 0.7mm above the thread major diameter.
A suitable CMP Products locknut shall be used to secure the product. See CMP Products catalogue for locknut options.
8. Cable glands do not have any serviceable parts and are therefore not intended to be repaired.

SPECIFIC CONDITIONS OF USE

1. All cable gland types and sizes are only suitable for fixed installations. Cables must be effectively clamped to prevent pulling or twisting.
2. The entry item component may be supplied with an alternative nearest equivalent recognised thread type and size to the metric thread, whilst maintaining a tolerance of fit, equal to or better than, a medium
fit to ISO 965-1 & ISO 965-3. Intended for use within existing installations only, that incorporate female thread types that are no longer permitted by the current edition of EN/IEC 60079-1, but comply with the
requirements of EN 50018:2000 & IEC 60079-1:2001 Product selection table
3. When the cable glands are supplied with an entry thread that is one size up from the nominal gland size, designated with the letter ‘B’ after the gland size, e.g. 32B****, they shall not be used with any adaptor
device. Available Entry Threads Combined Ordering
(Alternate Metric Thread Lengths Available) Overall Cable Across Across
4. The cable glands shall only be used where the temperature, at the point of entry, is in the following ranges: Reference
Diameter Flats Corners Cable
a. EPDM (Black): -60°C +130°C Cable Gland Standard Option Protrusion (*Brass Metric)
Shroud Gland Weight
5. For Ex d applications, cable gland types CA2F, CA2F-RC, CA2F-FC, CA2F-HC and CA2F- FF are to be installed in associated Ex d equipment having a minimum wall thickness as follows: Size Length

b. 12.5mm minimum for cable gland having entry thread sizes M90 x 2.0 to M115 x 2.0
6. Designed for appropriate Steel Tape Armour (STA), Steel Wire Armour (SWA), and appropriate braided cable. These cables must be extruded sealing (solid polymeric) completely surrounding the “core” (insulation 16S* M16 15.0 - - - 2.0 7.4 24.0 26.4 29.9 16S A2F 1RA PVC04 0.060

INSTALLATION INSTRUCTIONS FOR CMP CABLE GLAND TYPES A2F 4. Slacken the seal nut (3) to relax the seal (2).

CABLE GLAND COMPONENTS - It is not necessary to dismantle the cable gland any further than illustrated below
1. Entry Item 1 2 3
2. Seal
3. Seal Nut

PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING THE INSTALLATION

1. It is not necessary to dismantle the gland any further than illustrated below.

5. Pass the cable through the gland to the desired position, then tighten the seal nut using a spanner until resistance is felt (when the
seal contacts the cable). Tighten with a spanner one further turn.

2. Fit the gland into the equipment and fully tighten the entry item (1).

3. Determine the conductor length required to suit the installation and prepare the cable accordingly, removing part of the outer sheath
where required to reveal the insulated conductors.
