NOTES:
- Full installation instructions are supplied with adaptors and reducers, the instructions must be read prior to installation and
adhered to in full
- Unless otherwise stated ISO Metric entry threads have a 1.5mm pitch
- For Flameproof Exd applications the female thread into which the adaptor or reducer is to be fitted must comply with clause 5.3 of
EN 50018:2000 (clause 5.3 IEC 79-1)
- For NEC/CEC Explosion Proof applications an engagement of at least 8 full threads must be achieved for parallel threads and 5 full
threads must be achieved for tapered threads
- Where AR adaptors and reducers are fitted into non-metallic Increased Safety Exe enclosures they must be included within the
earth circuit of the system
- 316 Stainless Steel versions do not feature a marking band. This reduces the overall length of reducers by 5mm, it does not affect
the overall length of Adaptors/li>
- Adaptors are used where the thread size of the cable gland or connection device is larger than, or of an equivalent size to the
entry thread of the enclosure
- Reducers are used to reduce the entry thread of an enclosure to accept a cable gland or connection device with a smaller thread
- When ordering one needs to specify if IECEx or ATEX certification is required. ATEX versions are supplied as standard.
