Installation Notes

Only perform work on the components when the system is de-energized!
Working on devices when the system is energized can damage the devices.
Therefore, turn off the power supply before working on the devices.
De-energize all lights on the network!
When operating several lighting groups in different circuits, there is a risk that line
voltage can transfer to other lighting groups via the DALI data line in the event of
error. Therefore, generally de-energize all lighting circuits on your network when
working on data lines.
Observe IEC standard!
Observe the validity of DIN EN IEC 62386 when setting up your DAL network!
The following descriptions for setting up a DALI network are only
recommendations.
6.3.1

Module Assembly

Supply module is required!
The DALI Multi-Master Module has no power jumper contacts. The field supply
potential of the adjacent I/O modules in the node will not be passed to the
following modules. A supply module is therefore required to provide any
additional I/O modules.
6.3.2

Module Supply

Destruction of DALI subscribers due to misuse of the power supply
Please note that the WAGO power supply (Item No. 787-1007) may only be
connected to the DALI Multi-Master Module (753-647). Power for the DALI bus is
supplied indirectly via the DALI Multi-Master Module. Connecting to the DALI bus
directly can result in the destruction of connected DALI subscribers. Therefore,
never connect the WAGO power supply (787-1007) to a DALI network directly.
A DALI Multi-Master Module (753-647) must always be interconnected.
