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 (or 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).
Note: When fitted to a threaded entry, all tapered threads will automatically provide an ingress protection rating of IP6X.
4. Adaptors are manufactured from Brass, Nickel Plated Brass, Stainless Steel or Mild Steel. 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.
5. 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.
6. Ex db marked Adaptors can only be supplied with metric or NPT entry threads.
7. Equipment is not intended to be repaired. If damaged, equipment must be replaced.
8. 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 the enclosure and must be
secured with a locknut.
