TAC Xenta 400 I/O modules
4 Installation
4.2.3 Cables
Power and Communication
G and G0 (Power supply):
G, min. cross-sectional area ............................................... 0.75 mm²
G0 to TAC Xenta, min. cross-sectional area .......................1.5 mm²
C1 and C2 (Network):
The TP/FT-10 system allows the user to wire the control devices
with virtually no topology restrictions.
Min. cross-sectional area ................................ 0.65 mm² (22 AWG)
The max. wire length in one segment depends on the type of wire
and the topology, see the table below.
The wires are not polarity sensitive, but must be a twisted-pair.
For more details, please refer to the ”TAC Xenta Network guide”.
