Communication System Manual 3WN6 Circuit-BreakersVersion 1.0 (05/98)  Copyright Siemens AG 1998. All rights reserved. 27Hardware:-Communication-capable circuit-breaker 3WN6 (no. 1): Overcurrent releases D, E/F, H, J/K, N orP (no. 1a) are communication-capable when fitted with "additional functions 2". (no. 1b). Unlike astandard 3WN6, a communication-capable 3WN6 circuit-breaker has a communication module (no.1c). When additional measurement functions are required (e.g. voltage, frequency, power), acommunication module with measurement functions (no. 1d) must be ordered instead of the simplecommunication module. (Please refer to section 3.2, page 28 and section 3.1.1, page 37 for adescription of the functionality of the overcurrent release when combined with a communicationmodule/communication module with measurement functions.)-Order number:6- The type of overcurrent release ("D"..."P") can be determined from position 10 of the circuit-breakerorder number; enter a "7" in the eighth position of the order number if the circuit-breaker is to befitted with "additional functions 2".- The order number supplement for the communication module is "Z=F01".- The order number supplement for the communication module with measurement functions is"Z=F05" instead of "Z=F01".Example: For a draw-out circuit-breaker, complete with guide frame with overcurrent release "P","additional functions 2" and a communication module with measurement functions, the ordernumber is 3WN6 ......-7.P....-....-Z with Z=F05 +...Note 1: If the draw-out circuit-breaker and guide frame are ordered separately, 2 order numbers arerequired. In the case of a draw-out circuit-breaker without a guide frame, the sixth position of the ordernumber is "7":Circuit-breaker order number: 3WN6.7.-7....-....-Z with Z=F01 or F05Frame order number: 3WX3683-.A..0-Z with Z=R39 + ...Note 2: The position signaling switches cannot be ordered separately with communication-capabledraw-out circuit-breakers. They are included in the scope of supply and are located on the positiondisplay unit (bottom right) of the circuit-breaker.Note 3: In order to remotely close a circuit-breaker via PROFIBUS, the circuit-breaker must be fitted with amotorized operating mechanism and closing solenoid (Y1). To remotely open a 3WN circuit-breaker viaPROFIBUS, the circuit-breaker must be fitted with a shunt release of the type F1 or F2. The possibleswitching commands are illustrated in Fig. 5, page 32 and Fig. 6, page 32, Step 2.- One DP/3WN6 interface module for each 3WN6 circuit-breaker (no. 2).7Order number: 3RK10 00-0JC80-0BA1- A connecting cable from the SUB-D socket on the DP/3WN6 interface module to the SUB-Dsocket of the 3WN circuit-breaker (no. 2a). This cable is a standard 9-pole cable (1:1 connection)with a length of 3m and is supplied with the interface.- Connection from the "PROFIBUS-DP" terminal of the DP/3WN6 interface module to PROFIBUS-DP (no. 3). Two standard connectors are available for this purpose:Order number: 6ES7 972-0BB20-0XA0(for baud rates up to 12 Mbaud)- 24 V DC voltage supply (in acc. with DIN 19240; no. 4).Order number: 4AV2... or 4AV3...(See NSK catalog, section 16).6 cf. Table 3, page 30 for examples of circuit-breaker order numbers.7 Interface "DP/3WN6" was previously also referred to as interface "DP/RS485" and "kNS/DP".
