Wiring The Terminal Block - Siemens SIMATIC 505 User Manual

Wiring the Terminal
Block
SIMATIC 505 Interrupt Input Module User Manual
You can use either of the terminal blocks shown in Figure 2-10. Both
terminal blocks are removable. To wire the terminal block, follow the
procedure below.
1. Turn the terminal block, with the screw-heads facing you, until the
A-series of terminals is at the top and the D series is at the bottom.
2. Using Figure 2-7 as a wiring guide, start with the D's and loosen the
appropriate terminal block screws.
3. Strip back the insulation on the wires about 1/4 to 3/8 inch or one
centimeter. Use a 12–26 AWG or a 0.16–3.2 mm
either stranded or solid type.
(If you are using the side-accessible connector number 2587705–8010, a
spade or a ring lug may be attached to the end of the wire.)
4. Connect the end of the wire to the loosened terminal block screw and
tighten the screw firmly. Once the D's are completed, connect the C's,
and continue until the terminal block is completely wired.
NOTE: An easy-to-use, stick-on label is provided separately with space
available to write in the name of each input. Write in the corresponding
input names and apply the label to the flat side of the terminal block.
Appendix A contains a worksheet to help you document the input labeling.
