Page 7: Introduction
Introduction Included in shipment • 12M bus terminal order no. 6GK1 500-0AA10 Description of the product Function The 12M bus terminal is used to attach data terminal equipment (DTE) with an RS-485 interface to a bus cable. Note A maximum of 32 12M bus terminals can be connected to one bus segment. If other components, such as repeaters are connected to a bus segment, this reduces the maximum number of 12M bus terminals that can be connected. - Page 8 Introduction 1.2 Description of the product • 2 switches: – right-hand switch ("Termination") With the right-hand switch, you can terminate the end of an incoming, electrical segment (A1, B1) with the characteristic impedance (switch on). At the same time, the outgoing, electrical segment (A2, B2) is interrupted.
- Page 9 Introduction 1.2 Description of the product D-sub male connector The D-sub male connector is plugged into the D-sub female connector of the DTE and secured by screws. The 12M bus terminal requires a current of 90 mA with a voltage of 5 V supplied by the DTE between pins 5 (M5) and 6 (P5) of the D-sub male connector.

Page 18: Grounding Measures
Installation 2.3 Grounding measures Grounding measures If the 12M bus terminal is mounted on a DIN rail, the shield clamp makes largearea contact with the rail via an internal spring. To connect the cable shield with local ground, a connection between the DIN rail to local earth is adequate (this should be kept as short as possible). -
