SIMATIC 545/555/575 System Manual
Installing Series 505 Remote I/O Cables (continued)
Use the following procedures to attach a D-connector and terminal lugs to
your drop line cable:
1. Strip back 1.50 inches (38 mm) of the sleeving on one end of the cable.
There are three wires when the sleeving is stripped back; two wires
have color-coded insulation jackets and one (the shield) is bare.
2. Remove 0.13 in. (3.3 mm) of each color-coded insulation jacket to expose
the bare wires.
3. Install the cable wires to a 9-pin D-connector according to directions
provided by the connector vendor.
NOTE: Install the wire without insulation to pin #5 of the 9-pin D-connector.
Install the wires with the color-coded insulation to pins #3 and #8. It does
not matter which wire is installed to pin #3 or #8, but all connectors must be
installed identically. See Figure 6-6 for pinout information.
