Power Supply Configuration for 787-1007
If power supply is provided using a 787-1007 power supply unit, up to five DALI-
Multi-Master modules can be powered in a fully equipped system (DALI bus
slaves with total power consumption of max. 200 mA).
230 V power supply required!
Note that the 787-1007 power supply unit required 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.

Maximum cable lenght 300 m!
The maximum voltage drop of the DALI line should not exceed 2 V. Therefore,
the maximum cable length between the more distant components is depending on
the conductor cross-section limited to 300 m.
