INSTALLATION INSTRUCTIONS STATUTORY REQUIREMENTS SI 2016 No. 1107 (AS AMENDED)
1. Installation should only be performed by a competent person using the correct tools. 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 SHIPBOARD CABLE SEALING
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. FITTING FOR USE IN
Note: When fitted to a threaded entry, all tapered threads will automatically provide an ingress protection rating of IP66.
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
HAZARDOUS LOCATIONS 46ZM
(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 TYPE TC CABLE SEALING FIT-
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.
TING FOR USE IN HAZARDOUS
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 LOCATIONS 5PO7
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 Outer Seal Tightening Guide
have a perpendicular flat spot machined to facilitate sealing with an O-ring or Entry Thread Sealing Washer.
GLAND SIZE
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 Number of turns
suitable CMP Products locknut shall be used to secure the product. See CMP Products catalogue for locknut options 20S16 20S 20 25S 25 32 40 50S 50 63S 63 75S 75

PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING THE INSTALLATION
1. The PX2K type cable gland is supplied as a Universal Kit with two armour cones, the grooved armour cone (5a) is suitable for
Strip Armour, Tape Armour and Braided Cables, and the stepped cone (5b) is suitable for Wire Armour (SWA) cables. The PX2KX
gland only has one cone (5a) and the PX2KW only has one cone (5b). (PB Variants have an earthing device for the lead sheath).

2. Separate the gland components by removing the body and outer seal nut assembly. Pass the body and outer seal nut 8. Pass the compound tube (3) over the conductors until the stepped end is fully located with the armour cone (5). Pack more
assembly (6),(8), and the AnyWay clamping ring (7) over the cable, outer seal nut first. compound into place until the compound tube is fully filled

3. Prepare the cable by stripping back the outer sheath and braid / armour to suit the equipment. Expose the braid or armour
further so that it can be formed around the armour cone by cutting back the outer sheath by a length “L”. This length varies
slightly depending upon cable diameter, but typical values are shown below. The inner sheath should be long enough to just
pass through the armour cone when installed. On lead sheathed cables, the lead sheath should be long enough to just pass
through the armour cone when installed.

4. For direct make-off, fit the entry item to the equipment. Insert the armour cone (5a or 5b into the entry item (2) and pass the
cable through them until the braid or armour contacts the cone and make sure that it is evenly spaced around it. Tighten the body Then either use the outer seal tightening guide tape or table on the rear of the page to

Wrap the outer seal tightening guide tape around the cable to show the amount of
spanner turns needed (as shown here). Make sure the correct side of the outer seal
tightening guide tape is used depending on the cable gland size.
