2.1.1.7 Installation Notes
2.1.1.7.1 Module Supply
Attention
The WAGO DC/DC Converter, Item-No.: 288-895, must be used when
providing the module with DALI and DSI compliant 18 V supply. The
converter guarantees the electrical isolation between the DALI bus and the
internal data bus, which is required when using 230V consumer loads. The
internal power supply unit of the DALI/DSI Master module cannot be
decommissioned when using an external power supply unit.
Attention
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
module must not exceed 1 meter. Both devices must be installed in an
enclosure.

2.1.1.7.2 Module Assembly
Depending on the program functionality up to five DALI/DSI Master modules
can be connected in a fieldbus node.
Up to 400 mA can be delivered using a single DC/DC Converter 288-895. As
a result, the converter can supply three DALI modules in full extension, that
means each module is wired with a maximum of 64 electronic ballasts à 2mA
130mA.
An additional DC/DC Converter 288-895 is required to supply the other
DALI/DSI Master modules within the fieldbus node.
