Power Supply Configuration for 787-1007

If a power supply unit (787-1007) is used, it can supply power to multiple DALI
Multi-Master Modules (753-647). With total power consumption of 200 mA per
DALI line, up to five DALI Multi-Master Modules (753-647) can be powered with a
787-1007 power supply unit.
230 V power supply required!
Note that the 787-1007 power supply unit requires 230 V power supply.
Connection of power supply is made at the first DALI Multi-Master Module. Power
must be passed on via cable bridges for supply of the other I/O modules.

DALI Bus Line

The DALI bus control line consists of one pair of conductors which can be run
together with the 230 V installation.
For example, a 5-conductor cable can be used combining both the voltage supply
and the DALI control line.
The minimum cross section of the conductors depends on the cable length.
