5.1 Installing the hardware
Note
Always follow the installation, mounting and wiring guidelines for the individual
components provided in the appropriate manuals and accompanying notes.
Table 5-1: Table for installing and wiring the hardware
No.
1. Mechanically install the hardware.
(SINAMICS V20, motor if applicable, SIMATIC controller, operator panel, 24V power supply unit)
2. On the secondary side, connect the asynchronous motor (if applicable) to the SINAMICS V20.
On the primary side, connect the SINAMICS V20 to the main circuit.
3. Wire the 24 V DC connector of the SIMATIC S7 controller to the output of the 24V power supply
unit. If you are connecting an operator panel, wire also the OP's 24 V DC connector to the output
of the 24V power supply unit.
4. Establish the USS
SINAMICS V20. Provide bus termination and line polarization. For the bus design and wiring,
always comply with the appropriate RS-485 interface standard specifications.
For suggestions on wiring the networks with S7-1200 and S7-1500, please refer to the figures
following this table. For bus termination where no RS485 bus connector can be used, Siemens
offers a bus termination network (for the article number, see Table 2-2).

5. Use an Industrial Ethernet cable to connect the SIMATIC CPU (e.g., port 1) to the KTP600
operator panel, provided that you do not only want to simulate the HMI in TIA Portal.
6. Use an Industrial Ethernet cable to connect the SIMATIC CPU (e.g., port 2) to your development
system.
