Installation
!
CAUTION
This product description contains the specific settings and functions of the input/output module. In
addition to these instructions, the product descriptions of other system components, such as the
DDC4000e automation station, are to be observed.
!
CAUTION
Switching on the power supply of unparameterized products can lead to unforeseen consequences
such as malfunctions or material damage.
Switch on the power only after the device has been configured by the commissioning technician.
NOTE
The input/output module can be connected to an existing fieldbus or switch cabinet bus.
Further information can be found in the DDC4000 project planning documentation
Switch cabinet bus
When connecting the switch cabinet bus, use a cable of at least type JY(St)Y 2x2x0.8 Lg: two x two
leads stranded into a pair, plastic insulation and an electrostatic shield with a lead diameter of at least
0.8 mm. Use a stranded pair of leads for the data lines (+ and -) and another free lead for the
ground (0).
At the end of the switch cabinet bus (farthest 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 switch cabinet bus is 200 m.
