4 1. Safety Instructions / Warning - Read before start-up! The device may only be used for the intended purpose designed by for the manufacturer. The operation manual should be conveniently kept available at all times for each user. Unauthorized changes and the use of spare parts and additional devices which have not been sold or recommended by the manufacturer may cause fire, electric shocks or injuries. Such unauthorized measures shall exclude any liability by the manufacturer. The liability-prescriptions of the manufacturer in the issue valid at the time of purchase are valid for the device. The manufacturer shall not be held legally responsible for inaccuracies, errors, or omissions in the manual or automatically set parameters for a device or for an incorrect application of a device. Repairs may only be executed by the manufacturer. Installation, operation, and maintenance procedures should only be carried out by qualified personnel. Use of the device and its installation must be in accordance with national legal requirements and local electrical codes. When working on devices the valid safety regulations must be observed. Wird für die externe Antenne eine andere Dimensionierung gewählt als für die interne Antenne, so empfehlen wir den Reader funktechnisch neu überprüfen zu lassen! If there is a different dimensioning of the external antenna used as for the internal antenna, so we recommend to let recheck the radio approval. FEIG ELECTRONIC GmbH Page 4 of 12 N e-ID-B.doc

6 1.1. Connection of an external antenna: Instead of connecting the internal antenna, the reader can be operated with an external antenna as well. (Figure 1-2). The external antenna can be connected to X1 Pin 9 and Pin 10. Therefore the connection to the internal antenna must be interrupted. The simultaneously operation of internal and external antenna is not possible. external Antenna internal antenna cut off there 1 X1 10 internal antenna 1 10 X1 A Figure 1-2: alternative possibilities for the connection of antennas B FEIG ELECTRONIC GmbH Page 6 of 12 N e-ID-B.doc
