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 electrical 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.
OCT300-M1K-N2 - Diffuse mode photoelectric sensor, NAMUR, with terminal compartment. The diffuse mode photoelectric sensor emits light, which might be reflected by an object in the light beam and is received by the sensor itself. The sensor reacts on changes of the reflected light in an operating distance of 0 up to 300 mm. These changes are cause by objects accessing the light beam. The output mode can be chosen to be on or off, when reflected light is received.
OCS2000-M1K-N2 - Retro-reflective photoelectric sensor, NAMUR, with terminal compartment. The retro-reflective photoelectric sensor emits light, which is reflected by a retro-reflector and received by the sensor itself. The sensor reacts on interruption of the light beam. The retro-reflector can be positioned in an operating distance from 100 mm up to 2000 mm. The output mode can be chosen to be on or off, when reflected light is received.
1. The electrical data are to be taken from this certificate.
2. The sensor supply must be made by separately certified intrinsically safe circuits. Because of possible ignition hazards, which can arise from faults and/or transient circulating currents in the potential equalization system, galvanic isolation in the supply and signal circuits is preferred. Associated apparatus without galvanic isolation may only be used whether the appropriate requirements according to IEC 60079-14 are met.
3. The device shall be installed in a way that propagating brush discharges are avoided. If the device is installed according to the instructions of the manufacturer, no dangerous electrostatic charge is expected due to the construction of the device.
4. The tightness for the purposes of zone separating measures for the mounting across the boundary between different zones is not covered by this certificate and must be ensured by appropriate measures of installation.
