¨
Insert the screwdriver into one of the square open -
ings and tilt it slightly towards the centre of the ter -
minal in order to open the contact point sufficiently.
¨
Push the strand end all the way into the corre-
sponding round opening.
¨
Pull out the screwdriver and check whether the strand is secure in the terminal.
¨
Repeat this procedure for all the required strands.
4.2.4 Installing the bus terminating resistor
Each end of a data bus line must be terminated by a 120 Ω bus terminating resistor. For this, both
connections of the resistor are, like the strand ends of a cable, routed into a terminal.
A bus terminating resistor is already connected when the unit is delivered. However, this is only
required if iFerm Nano Terminal is installed at the end of the data bus line, see “4.2.5.4 Data bus
termination” on page 14 . Otherwise you must remove the bus terminating resistor in order to
connect the second bus cable at this location. You then connect the resistor to the other, free end
of the data bus line.
4.2.5 Applications
The example graphics show the cable routing schematically as a plan view. The following compari -
son is intended to show how the schematic representation should be interpreted:
↔
When making the cable connections, pay attention to the locations recommended in the examples
for routing the cables and the installation instructions in the preceding chapters.
