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.
Motors type ASA... frame size 63-355 are designed for use in potentially explosive atmospheres of group IIC, temperature class T5, T4 or T3 (EPL Gb), and group I (EPL Mb) and they are achieved in type of protection “d” – flameproof enclosure (both the enclosure of the motor and the terminal box).
Additionally, the terminal box can be designed also with increased safety “e” type of protection for frame size 80-355.
Motors type ASA... frame size 63-355 are also designed for use in air – dust atmospheres (group III C – conductive dusts EPL Db).
These motors can be produced in four designs :ASA... and E2-ASA… for standard versionsASA-VF… and E2-ASA-VF… for versions with forced ventilationASAF… and E2-ASAF… for versions with electromagnetic brakeASAen… and E2-ASAen… for versions with encoders
-The width of flameproof joints is more than the values specified in the tables of the IEC 60079-1 standard.-The gap of flameproof joints is less than the values specified in the table 2 of the IEC 60079-1 standard.-The special conditions for safe use are complemented by those described into the certificates of conformities of encoders and/or electromagnetic brake, when relevant.-For the risk from electrostatic discharge, the user will have to read the instructions.-The screws used for the assembly of the various parts of explosion-proof enclosures must be of quality higher or equal to 8.8 in case of motors frame size 63 – 250.-The screws used for the assembly of the various parts of explosion-proof enclosures must be of quality higher or equal to 12.9 in case of motors frame size 280 – 355.-The equipment has to be used only under certain positions, the user will have to read the instructions.-The surface temperature determination was based on operation within “Zone A” (IEC 60034-1), at ± 5 % of the rated voltage.
The other conditions are stipulated in the instructions.
