Fieldbus
When connecting the fieldbus, use a cable of at least type JY(St)Y 2x2x0.8 Lg: two x two wires,
twisted to a pair with plastic insulation and an electrostatic shield with a wire diameter of at least
0.8 mm. Use a stranded pair of wires for the data lines (+ and -) and another free wire for the ground
connection (0).
At the end of the fieldbus (furthest point from the DDC controller), install a terminating resistor of
about 180 ohms between both data lines (+ and -). The terminating resistor is included with the DDC
controller.
The maximum cable length for the Fieldbus is 2000 m.
