5-22 SPECIAL INSTRUCTIONS FOR ELECTRONIC SUBSYSTEMS E UROCARGO Euro 4/5 Table 5.24 Use electric/electronic equipment in conformity with the EEC directives on electromagnetic compatibility; that is use components suited for applications on the vehicle and marked ”e.”, the ”CE” mark is not sufficient. Below there is an example of a mark as prescribed by the current European directive 2004/104EC valid for electromagnetic compati- bility in the automotive sector: Figure 5.9 114476 a ≥ 6 mm In case of doubt, refer to the IVECO Support network.
These levels are assured if the device comes from ”IVECO spare parts” or is certified according to the related international standards such as ISO,CISPR,VDE,etc.... If equipment is employed that as its primary or secondary source of power uses the civil electric mains (220V AC), it must have characteristics in line with the IEC regulations. Transceiver systems The most frequent applications concern: - ham transceiver equipment for the cb and 2metre bands; - transceiver equipment for cell phones; - gps satellite navigation and receiver equipment.
