4 Abbreviated terms No abbreviated terms are listed in this document. This clause is the placeholder for the technology specific parts of the 61980 series. 5 General The supply device (see Figure 1 ) shall be rated for one or a r ange of standard nominal voltages and frequencies as listed in IEC 60038. The supply device shall be so designed and constructed that, in normal use, it “connects” (without a galvanic connection) to the EV device in a manner that assures that wireless powe r transfer functions safely, and its performance is reliable and minimizes the risk of danger to the user or surroundings. Compliance is achieved by fulfilling the relevant requirements in this document and the technology specific parts of the IEC 61980 series. Unless otherwise stated, tests may be conducted on separate samples. Multiple tasks may be conducted on the same sample at the discretion of manufacturers. Unless otherwise specified, all tests shall be carried out in a draft-free location and at an ambient temperature of 20 °C ± 5 °C. For equipment designed to be used at altitudes above 2 000 m, it is necessary to take into account the reduction of the dielectric strength and the cooling effect of the air. NOTE The requirements for a fixed installed supply device is defined in IEC 60364-7-722. 6 Classification General 6.1 The supply device is classified according to – power transfer technology, – environmental condition, – electric connection to supply network, – access, and – protection against electrical shock. Additional classifications can apply depending on the power transfer technology. These classifications are described in the technology specific parts of the IEC 61980 series.
10 Protection against electric shock 10.1 General requirements Hazardous live parts shall not be accessible. Protection measures against electric shock under single fault conditions shall be implemented. Where supply devices are connected through a single connection to the supply network and can be used simultaneously, they shall have individual overcurrent and fault current protection incorporated. A supply device shall not have multiple connecting points. NOTE 1 In the following countries, national regulations require shutters or equivalent protection methods with equivalent safety levels, for example installation heights, blocking objects against touch ability, interlocking, locking cover: FR, SE, IT. NOTE 2 In the following countries, alternative installation rules are applicable: JP. 10.2 Degrees of protection against access to hazardous-live-parts Requirements for the technology specific components are specified in the technology specific parts of the IEC 61980 series. 10.3 Stored energy – Discharge of capacitors 10.3.1 Stored energy under abnormal or fault conditions The stored energy between hazardous live parts that may be accessible under abnormal or fault condition or between live parts that may be accessible under abnormal or fault condition and exposed conductive part shall be less than or equal to 0,2 J under abnormal or fault condition.
