CBU-DCS-LR

CBU-DCS-LR draws its operating power directly from the DALI bus. For this reason, it is important to make sure that the DALI bus is externally powered. If CBU-DCS-LR is connected directly to a DALI sensor or a DALI driver, these products must have an integrated DALI bus power supply. 

CBU-DCS-LR draws 5 mA in idle mode with 30 mA peak current from the DALI bus. Use 0,5-1,5 mm2 solid conductor electrical wires. Strip the wire 6-8 mm from the end. Press the buttons on top of the dimmer case and insert the wires into the corresponding holes. The polarity of DA1 and DA2 does not matter. 

CBU-DCS-LR has two sets of connectors. These connectors are internally connected in parallel with each other. This way the DALI bus can be routed through the product for easy installation. 

CBU-DCS-LR, as any other Casambi product, should not be placed in a metal enclosure or next to large metal structures. Metal will effectively block radio signals which are crucial to the operation of the product. A thorough connectivity testing is strongly recommended in the installation site.
