Installation Guide
1.
All Redapt products should be installed in accordance with all relevant Installation Standards and Codes of
Practice.
BS EN 60079-14: 1997. Electrical Installations in hazardous areas (other than mines)
2.
Installation of Redapt products should only be carried out by an engineer trained in cable gland installation.
3.
Under no circumstances should installation be carried out under live conditions.
4.
The installer should ensure that no damage occurs to any thread or form of seal during installation. Where
component is plated care should be taken to prevent damage or chipping.
5.
Threaded Entries Components can be installed directly into threaded entries and the recommended torque
applied.
6.
Clearance Holes Clearance holes should be 0.5 mm to 1mm larger than the major diameter of the male thread.
Components installed in clearance holes should be secured with an appropriate sized locknut to recommended
torque.
7.
Maintaining IP 54 Rating In order to maintain such an IP rating the installer should ensure that parallel threads
engage to 6 full threads and tapered thread to 5 full threads.
8.
Maintaining IP 66-67-68 Rating In order to maintain the IP Rating of a component, the above thread
engagement must be attained. The surface of the enclosure should also be clean and free from dust or moisture
before assembly. In order to maintain IP 66-67-68 the installer must ensure that either the sealing washer is in
the correct position or that the O Ring seal is seated in the groove provided. A non-hardening thread sealant
may be used to provide protection.
9.
If a serrated washer is used it should not be installed in such a way that it may impair any IP Rating.
10.
Recommended Installation Torque In order to maintain the integrity of the enclosure it is important that an
installation torque as detailed below be applied.

Routine Checking and Maintenance
1.
All Redapt products should be checked during routine maintenance of the enclosure.
Special Notes
Non standard threadforms conforming to Table 3 of BS EN 50018 are available as certified components.
Non standard certified threads- An installation torque appropriate to the nearest metric size should be applied.
E.g. Non standard male thread size M24. Use Installation torque of an M25 male thread.
Aluminium variants are not permitted for Group 1 applications.
EExe equipment should not be used with EExd equipment.
Two adaptors installed in series is not permitted under certification.
The metallic AD-D, RD-D, AD-E and RD-E series are capable of operating in surrounding temperatures between
60° C to + 400° C, providing they are not used in conjunction with any other sealing method.
AD-D, RD-D, AD-E and RD-E Series provide IP54. An appropriate sized sealing washer can provide IP66-67-68.
