UNION TYPE PX780REX FOR CONNECTING CONDUITS TO ENCLOSURES OR
CONDUITS TO EACH OTHER USING RAPIDEX RESIN 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).
ACCESSORIES
The following accessories are available from CMP Products, as optional extras, to assist with fixing, sealing and earthing :-
Locknut | Earth Tag | Serrated Washer | Entry Thread (I.P.) Sealing Washer
