Notes: • The connection cable between the control unit and connection box must be provided and
laid by the customer. When choosing the cable type, make sure that the core/core effec-
tive capacitance is less than 110 pF/m and the minimum core cross-section is 0.5 mm
2
(AWG20).
We recommend the cable type UNITRONIC Li2YCYv(TP) 2x2x0.5 mm
2
with reinforced
outer sheath (from Lappkabel).
• For wiring the bus version with two connected sensors (see Fig. 2.3) the maximum cable
length is reduced by half.
To implement longer cable lengths:
– Use larger core diameter e.g. cable type with 4 core pairs and 2 core pairs for power
supply
– Use MCU with high-capacity power supply
Both implementations are available from the manufacturer on request.
• For bus wiring the manufacturer set termination has to be deactivated in those system
components, that are not on the cable end (see Service Manual Section 3.1).
3.3.5 Installing and Connecting the Interface and I/O Module Options
Plug these modules onto the top hat rail in the MCU (see Fig. 3.22) and connect them with
the cable with plug to the corresponding connector on the processor board (see Fig. 2.21).
