This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
The apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
Comprising a metallic enclosure with non-metallic window, the Control Unit (model 7500…) is provided with mounting means for installation into framework, panels or enclosures. The Control Unit may also be identified as Main Control Unit or Purge Control Unit herein. Field wiring terminals and a user interface touch screen are provided within the enclosure of the Control Unit, along with field wiring threaded entries provided in the rear for incoming and outgoing field wiring. Internal and External earthing and bonding facilities are also provided.
Optional accessories identified by their own part numbers are available to the end user and have been considered as supplementary parts to the Control Unit evaluation where necessary, these include:
A Vent for installation into a purged and pressurised end equipment enclosure and is only for use in conjunction with the Control Unit as specified on the product label and in the installation instructions. All vent types are provided with spark arrestors. The end user shall take account of the installation requirements of the Vent to comply with requirements of the end product certification as specified in the installation instructions.
A metallic conduit hub provides additional threaded entries for field wiring purposes, thus expanding the maximum entries.
A mounting arrangement, external boxed or panel mount provides mounting methods for end user installation of the control unit and a manually operated valve manifold. The mounting means doesnot supplement the Control Unit type of protection, nor provide independent type of protection. It may be provided with non-electrical components which have not been included in the Control Unit evaluation.
Please see Annex for additional information.
