Connection
WARNING
Contact with live parts of electrical domestic installation can cause death due to electric shock.
Only connect the device and switch on the power supply if you are qualified to do so. Be sure to
comply with VDE guidelines and local wiring regulations.
!
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 bus systems of the switch cabinet bus (DDC3000) and the CAN bus (DDC4000) are identical.
Accordingly, the technical information for the switch cabinet bus also applies to the CAN bus.
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.
NOTE
The DDC3000 / DDC4000 system already includes terminating resistors.
Modbus
Modbus RTU is used as the protocol for the foreign bus connection.
