RF300 system planning 4.7 EMC Directives The description is intended for "qualified personnel": ● Project engineers and planners who plan system configurations with RFID modules and have to observe the necessary guidelines. ● Fitters and service engineers who install the connecting cables in accordance with this description or who rectify defects in this area in the event of interference.
RF300 system planning 4.7 EMC Directives EMC measures usually consist of a complete package of measures, all of which need to be implemented in order to ensure that the plant is immune to interference. Note The plant manufacturer is responsible for the observance of the EMC guidelines; the plant operator is responsible for radio interference suppression in the overall plant. All measures taken when setting up the plant prevent expensive retrospective modifications and interference suppression measures.
RF300 system planning 4.7 EMC Directives ● Routing HF cables: avoid parallel routing of HF cables. ● Do not route cables through the antenna field. Shielding for the cables ● Shield the data cables and connect the shield at both ends. ● Shield the analog cables and connect the shield at one end, e.g. on the drive unit. ● Always apply large-area connections between the cable shields and the shielding bus at the cabinet inlet and make the contact with clamps.
RF300 system planning 4.7 EMC Directives ● Only devices fulfilling limit class A of VDE 0871 may be used in a plant. ● Interference suppression measures must be introduced on all interference-emitting devices. This includes all coils and windings. ● The design of the system must be such that mutual interference between individual components is precluded or kept as small as possible. Information and tips for plant design are given in the following sections.

Erect suitable damping materials between the antennas. Reduce the power of the readers. Please follow the instructions in the section Installation guidelines/reducing the effects of metal Coupling paths A coupling path has to be present before the disturbance emitted by the interference source can affect the system.

RF300 system planning 4.7 EMC Directives If the control cabinet panels are insulated from each other, a high-frequency-conducting connection can be established using ribbon cables and high-frequency terminals or HF conducting paste. The larger the area of the connection, the greater the high-frequency conductivity. This is not possible using single-wire connections.
RF300 system planning 4.7 EMC Directives Filtering of the supply voltage External interference from the mains can be prevented by installing line filters. Correct installation is extremely important, in addition to appropriate dimensioning. It is essential that the line filter is mounted directly at the cabinet inlet. As a result, interference is filtered promptly at the inlet, and is not conducted through the cabinet.

The valves and motor brakes are frequently forgotten. Fluorescent lamps in the control cabinet should be tested in particular. 4.7.7 Equipotential bonding Potential differences between different parts of a plant can arise due to the different design of the plant components and different voltage levels.

Equipotential bonding should not be confused with protective earthing of a plant.
RF300 system planning 4.7 EMC Directives Figure 4-29 Cable shielding The shielding bus should be connected to the control cabinet enclosure in a manner allowing good conductance (large-area contact) and must be situated as close as possible to the cable inlet. The cable insulation must be removed and the cable clamped to the shielding bus (high-frequency clamp) or secured using cable ties. Care should be taken to ensure that the connection allows good conductance.

5 Readers Overview The reader ensures inductive communication with the transponders, and handles the serial connection to the communication modules or the 8xIQ-Sense module. Communication between the transponder and reader takes place over inductive alternating fields. The transmittable data volume between reader and transponder depends on: ● the speed at which the transponder moves through the transmission window of the reader. ● the length of the transmission window.
