Installation Notes

Only perform work on the components when the system is de-energized!
Working on the devices when the system is energized can damage the devices.
Therefore, turn off the power supply before working on the devices.
Observe IEC 62386!
Always observe the validity of IEC 62386!
The information given below on setting up a DALI network should be seen as
recommendations only.
6.2.1

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.
6.2.2

Module Supply

Required accessories: DC/DC converter, Item No.: 753-620 or power supply
unit for DALI-Multi-Master module, Item No.: 787-1007!
A suitable DALI power supply unit is required for the 18V power supply to the
DALI network via the DALI Multi-Master module which is compliant with the
DALI guideline, such as the DC/DC converter, Item No. 753-620, or the power
supply unit with the Item No. 787-1007.
These items provide for reliable electrical isolation between the DALI bus and the
data bus that is required for installation of 230V electrical loads.
EMC regulations comply by DIN rail grounding!
In order to meet the EMC regulations, the DC/DC converter must be connected to
ground using the appropriate FE-connection (S) on the rail.
The length of the power supply cable between the DC/DC converter and the
DALI Multi-Master Module must not exceed 1 meter.
