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.
The system consisting of AR-0010 and AR-0020 is used for communication between a hydrogen fuel station and a vehicle to be gassed up. The AR-0020 (RDI Ring) can be used inside a Zone 1 area whereas the AR-0010 (RDI control, two versions “Standard” or “Barrier”) is an associated apparatus to be installed outside the explosive area.
The RDI control is divided into two different versions. One version includes a communication interface (RS485) wheres the other version is not equipped with such an interface.
AR-0010: Uo = 7.15 V, Io = 0.151 A, Po = 0.54 W, Ri = 100 Ohm, Um = 60 V, Characteristic trapezoidal
AR-0020: Ui = 7.15 V, Ii = 0.151 A, Pi = 0.54 W, Ci = 3.88 µF, Li = 0.0 mH (negligible)
It must be ensured that, along the cable way inside and outside the hazardous area, a common equipotential bonding is built between the RDI Control Box AR-0010 “Standard” or “Barriere” and the RDI Ring AR-0020. The GND terminals X3-1 to X3-3 of the RDI Control Box AR-0010 shall be connected to a common potential equalization.
