Communication System Manual 3WN1, 3WS1 Circuit-BreakersVersion 1.0 (02/98) Copyright Siemens AG 1998. All rights reserved. 85Step 4: Connect 3RK1002 interface module to PROFIBUS-DP 58Now you can wire the appropriate 6ES7... connector (up to 12 Mbaud) to the PROFIBUS-DP cablebased on the baud rate required on the bus59 (cf. connector user guide). Then plug the wired connectorinto the "PROFIBUS-DP" socket on the interface module.(--> see also section 4.5.2.2.3, page 93)Step 5: Connect 3RK1002 interface module to 3WN1/3WS1 circuit-breakerConnection of 3WN1/3WS1 <--> 3RK1002 connecting cable: This cable is supplied with the interface and is plugged into the 3WN1, 3WS1/3RK1002 adapter(9-pin SUB-D socket), which is fitted on the circuit-breaker at the factory, and into the "3WN1, 3WS1"(9-pin SUB-D) socket on the front of the interface module.Note Installation procedure! All communication-capable circuit-breakers (fixed-mounted) and allcommunication-capable guide frames (for draw-out circuit-breakers) arefitted with a "3WN1, 3WS1/3RK1002" adapter at the factory.This 3WN1, 3WS1 adapter can also be ordered as a spare part using thefollowing order numbers:• Adapter "3WN1/3WS1/3RK1002" (0.4 m) for 3WN1/3WS1 fixed-mountedcircuit-breakers, comprising one SUB-D socket and free cable ends, andincluding mounting materials.Order number: 3WX3145-3JA00(--> see also section 4.5.2.2.2, page 92)Step 6: Connect 3RK1002 interface module to voltage supplyConnect the 24 V DC voltage supply (DIN 19240) to the interface module: The interface module is fitted with a 4-pole screw terminal to facilitate the through connection of the24 V supply.(--> see also section 4.5.2.2.4, page 94)58) This assumes that conventional copper conductors are used for PROFIBUS-DP. If fiber optic conductorsare used, converters from fiber optic to copper conductors must be fitted.59) The maximum possible baud rate corresponds to the maximum baud rate of the slowest field device.
