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

INSTALLATION INSTRUCTIONS FOR CMP CABLE UNION PX780REX
UNION COMPONENTS - It is not necessary to dismantle the union any further than illustrated below
1. Entry Item
2. Serrated Flamepath
3. Nut
4. Conduit Connector
5. Washer
6. Resin Dam
7. Compound Tube
8. Thread Shield
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING THE INSTALLATION
1. Prepare the cable by removing the outer sheath from the cores so that they are exposed within
the Compound Tube when finally assembled.
1 2 3 4
NOTE: THERE IS NO NEED TO DISSASSEMBLE THE UNION
3. Feed the cables/cores through the union.
If the installation uses only cores (i.e. no cable sheath) then
electrical tape must be wrapped around the cores at the position
at which it will engage the resin dam.
Use the length of the union as a guide to position the tape as
shown above (guide length “L”)

678
2. Remove any bedding or fillers from around the cable cores. If the cable cores have screens,
these should be unwound and then twisted together to form a single core.
This single core and/or any drain wires present should be sleeved with some heat shrink tubing.
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.

4. Mix the Resin and apply as per RapidEx instructions.
5.1 When the Resin has cured the Entry Item (1) should be removed from the assembly and fully tightened into the
apparatus.
5.2 Tighten the Conduit Connector (4) onto the conduit and then tighten to the Entry Item (1) using the Nut (3) to
complete the installation.
