● The connection cable between the control unit and junction box or terminal
box must be provided and laid onsite. When choosing the cable type, make
sure the lead/lead operational capacity is less than 110 pF/m and the
minimum lead cross-section is 0.5 mm
2
(AWG20).
We recommend using cable type UNITRONIC Li2YCYv(TP) 2x2x0.5 mm
2
with reinforced outer sheath (from Lappkabel).
● When connecting bus versions with several sensors (
p. 14, Fig. 3), the
maximum cable length is reduced as follows depending on the number of
sampling points connected:
– Cable length with 1 sampling point = 1000 m
– Cable length with 2 sampling points = 500 m
To implement longer cable lengths:
– Use larger lead diameter e.g. cable type with 4 lead pairs and 2 lead
pairs for power supply
– Use an MCU with more powerful power supply unit
Both solutions are available from the manufacturer on request.
● For bus wiring, the set termination set at the factory must be deactivated in
those system components not at the line end (see Service Manual Section
3.1).
