Noteson the accompanying documents for connectors/ terminalablocks (B1)
Special equipment (SA) is specifically highlighted in the notes
column. For connectors, which are installed in special
equipment, the special equipment is specified in the notes
column in the row in front of the connector designation. For
connectors, which are installed as standard, special
equipment specification is noted directly at the respective jack
and/or connector.
The feed of the terminal blocks is shown by means of an
arrow pointing to the left, the outputs by means of arrows
pointing to the right. The grouping of the individual variants/
special equipment (SA) is highlighted by means of broken
lines. All outputs to components, which are installed as
standard, are listed up to the first broken line.
