4.4.3

Connection of 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 the S7 300 or ET200M system, the SIMATIC CPU or IM 153 and SIWAREX FTC
must be connected to the same 24 V supply.

Connections to Front Terminal

The SIMATIC construction guidelines apply for connecting the 40 pin connector.

Flexible cables with a cross-section of 0.25 to 1.5 mm

can be used. Remove the

insulation from the cable for 6 mm and install wire end sleeves.

4.4.5

Load Cell Connection

Sensors equipped with strain gauges and that meet the following conditions can be
connected to the SIWAREX FTC:

Characteristic value 1.... 4 mV/V

Supply voltage of 10.2 V is permitted

The connection is made to the 40 pin front connector. The connection should be
made using the cable described in chapter
