IMPORTANT NOTES FOR INSTALLERS

1. Read all instructions before beginning installation. Installation shall only be performed by competent, suitably trained personnel (in accordance with EN/IEC 60079-14) using the
correct tools; spanners should be used for tightening.

2. Inspection and maintenance shall only be performed by competent, suitably trained personnel (in accordance with EN/IEC 60079-14 (Initial Inspection) and EN/IEC 60079-17).

3. 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 installers 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 IP66.

4. The standard product temperature range is -60°C to +130°C. The equipment should not be used outside of this range.

5. Cable glands do not have any serviceable parts and are therefore not intended to be repaired.

6. Cable glands are manufactured from Brass, Nickel Plated Brass, Stainless Steel, Mild Steel or Aluminium, with Silicone seals. The end user shall consider the performance of these
materials with regard to attack by aggressive substances that may be present in the hazardous area. Consideration should be given to potential degradation due to galvanic
corrosion at the interface of dis-similar metallic materials.

7. It is the end user’s responsibility to ensure the equipment materials are suitable for their final installation location. If in doubt consult CMP Products Limited.

8. Ex db marked cable glands can only be supplied with metric or NPT entry threads.

9. Once installed do not dismantle except for inspection. An inspection should be conducted as per IEC / EN 60079-17 by a qualified person. After inspection the gland should be
re-assembled as instructed, ensuring the outer seal nut is correctly tightened to ensure the cable is secured.

10. 3/8” NPT, Ingress Discs (all materials) and Aluminium Cable Glands not to be used for Group I applications.

11. 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.

12. 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.

13. Enclosure will need to be sufficiently strong to support the cable and cable gland assembly. Enclosure entries must 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.

14. CMP Products recommends 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.

15. 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 (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).

PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING THE INSTALLATION

USING CMP INGRESS DISCS

CMP Ingress Discs are used as a means of maintaining the
integrity of the enclosure and exclude dust and moisture,
enabling the Cable Gland to be installed prior to the cable.

Ingress discs are rated to IP66.

Do not re-use the disc once removed.

1. Fit the gland into the equipment and fully tighten the entry item (1). RA2F100 ‘O’ ring face seal will engage when fully tightened

*Seal nut (3) should be

loosened to relax the seal

(2) then tightened using

finger pressure until light

resistance is felt, then

turn the seal nut:

16 – 25 = 2 turns

32 – 75s = 2.5 turns

with a spanner

3. Slacken the seal nut (3) to relax the seal (2).

4. Only using finger pressure, tighten the seal nut until light resistance to tightening

is met.

Then either use the seal tightening guide tape or table on the rear of the page to

determine how much further to tighten the seal using a spanner (using the outer seal

tightening guide is recommended).

Wrap the 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 seal tightening guide

tape is used depending on the cable gland size.

2. 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.
