FOR TERMINATION OF UNARMOURED, BRAIDED CABLES AND EXTRA
HARD CORD USEAGE CABLES, FOR USE IN EXPLOSIVE ATMOSPHERES.
TECHNICAL DATA
EXPLOSIVE ATMOSPHERES CLASSIFICATION
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.
Note: When fitted to a threaded entry, all tapered threads will automatically provide an ingress protection rating of IP68.
3. 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 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.
ACCESSORIES
The following accessories are available from CMP Products, as optional extras, to assist
with fixing, sealing and earthing :-

SCAN FOR INSTALLATION VIDEOS
1. The glands when used for terminating braided cables are only suitable for fixed
installations.
2. Cables must be effectively clamped to prevent pulling or twisting. The PXB2K,
PXB2KX and PXB2KW glands are to be protected from hydraulic fluids, oils, and
greases when applied for Group I use.
3. The PX range of cable glands with entry threads smaller than a M25 (or
equivalent) size shall not be used for Group I, EPL Mb applications where there
is a ‘high’ risk of mechanical damage.
4. Connectors with metric entry threads are only suitable for Areas Classified in
ZONES unless fitted with an approved Metric to NPT thread conversion adaptor.
5. Installation must be according to CEC wiring method for the types of cables that
can be used in Class I, Div. 1 and 2 and Class I, Zone 1 and 2 Classified Areas,
according to 60079-14 installation wiring method restrictions.
6. Installation must be according to US (NEC) wiring method for the types of cables
that can be used in Class I, Div. 1 and 2 and Class I, Zone 1 and 2 Classified
Areas, according to 60079-14 installation wiring method restrictions.
7. Prior to comissioning or operation of electrical equipment in the presence of
flammable materials, the sealing compound must be cured for 24 hours at a
temperature of no less than 5°C (41F).
8. For Metric and NPT threads, the installer shall follow guidance from the NEC
or CEC to ensure that the enclosure entry meets the requirements for thread
enagagement.
9. When the connector is supplied with metric entry threads, a CMP Entry Thread
Washer should be fitted between the connector and the enclosure to prevent the
ingress of moisture or dust into the enclosure. Thread tape must not be applied
to the entry threads.
10. Before installing the connector, ensure that the connector thread form and
enclosure thread form are compatible.
11. For guidance on mixing the RapidEx, please refer to FI320
12. Class I, Div 1, Groups ABCD is only applicable to TC-ER-HL type cables.

INSTALLATION INSTRUCTIONS FOR CMP CABLE GLAND TYPES PXSS2K-REX
CABLE GLAND COMPONENTS - It is not necessary to dismantle the cable gland any further than illustrated below
1. Resin
2. Entry Component “A”
3. Compound Tube
4. Resin Dam
5. Spacer
6. Main Item
7. Skid Washer
8. Outer Seal
9. Outer Seal Nut
10. Thread Shield
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING THE INSTALLATION
2. Feed the cable carefully into the entry item (2) through the resin dam (4). Reassemble the gland and adjust the position of the
cable if necessary to that the outer sheath just protrudes through the resin dam. (Use length ‘L’ as a guide for positioning the cable).
Tighten the outer seal nut enough to secure the gland. Make sure thread shield is in place.
3. Refer to ‘RapidEx Resin’ assembly instructions to fill the connector Compound Tube with the required amount of
resin. The resin should not be mixed or applied at temperatures below 5°C (40°F). If the general ambient temperature
is below 5°C (40°F) please follow the instructions on CMP TDS 613 before proceeding (avaiable on CMP website)
1. Remove any bedding or fillers from around the cable cores. If the cable cores have screens, these should be unravelled and then
twisted together to form a single core. This single core and any drain wires present should be sleeved with some heat shrink tubing.
Note: If the outer sheath is too large to pass through the spacer then wrap some electrical tape around the cores at the point they pass
through the resin dam.
Ensure Resin Dam is
in position in the
gland and making a
good seal against the
inner sheath.
Resin Dam
with poor contact
with cable cores.
Do not disassemble the gland to inspect the Resin Dam, diagrams are for representation.
If the installation only uses cores
(i.e. no cable sheath) at the
position of the resin dam then
electrical tape must be wrapped
around the cores at that position
to make a good seal between the
cores and the resin dam.
4. Once the resin has cured remove the thread shield (10). Loosen the outer seal nut, remove the main item (6) and outer seal nut
assembly (7,8,9) from the entry item (2). Fit the entry item into the equipment.
5. Re-install the cable assembly into the entry item and fully tighten the main item (6) onto the entry item (2). Tighten the outer
seal nut (9) until it comes to an effective stop. This will occur when :-
A) The outer seal nut (9) has clearly engaged the cable and cannot be further tightened
without the use of excessive force by the installer.
B) The outer seal nut (9) is metal to metal with the main item (6).
Electrical tape MUST be wrapped around the tips of
the cable cores. This is to ensure the cable cores are
together and also to cover any sharp edges that
could potentially tear the Resin Dam during
installation.
