Connecting The 24 V Power Supply - Siemens SIWAREX FTA Device Manual

Hardware Planning and Assembly
Shield clamps must be ordered separate to the grounding elements. The area
covered by the shielding clamp is to be chosen corresponding with the cable
diameter.
Approximately 1.5 cm of the cable insulation must be exposed in the area of the
cable to be fastened with the shielding clamp. The exposed shielding is then
pressed firmly against the grounding element with the shielding clamp.
The following figure shows a proper shielding clamp assembly

The shielding should be pressed against the shielding rail by the shielding clamp.

Connecting the 24 V power supply

The 24 V supply voltage is connected with a screw connector. The connection is found
in the lower area of the module groups next to the D-sub connector for RS 232.
Note
In central operation in the S7 300 system, the SIMATIC CPU and SIWAREX FTA
is to be connected to the same 24 V power supply.
