4.2.4 Cables
Power and Communication
G and G0 (Power supply):
G, min. cross-sectional area ...........................0.75 mm² (19 AWG)
G0 to TAC Xenta, min. cross-sectional area....1.5 mm² (16 AWG)
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”.
One of the following cable types must be used:
If a shielded communication cable is used, the shield must be grounded
at one point only.
Redundant wires (second pair of Siemens J-Y(st)Y) are cut at the end of
the shield.
