Description
CBU-A2D is a Bluetooth controllable, Casambi enabled 2 channel 0-10V/DALI controller. CBU-A2D has a universal 100-
277 VAC input voltage range,
CBU-A2D can control one or two 0-10V controllable LED drivers, or it can control a tunable white LED driver with two
0-10V control interfaces. The product can also be configured into a DALI mode where it can be connected to a DALI LED
driver or DALI sensor for presence and/or daylight harvesting functions.
CBU-A2D can be controlled with Casambi app which can be downloaded free of charge from Apple App Store and Google
Play Store.
Different Casambi enabled products can be used from a simple one luminaire direct control to a complete and full fea-
tured light control system where up to 250 units form automatically an intelligent mesh network.

WARNING:

Installation
Make sure that the mains voltage is switched off when making any connections. Use 0.5-1.5 mm
2
solid or stranded con-
ductor electrical wires. Strip the wire 6-7 mm from the end. Insert the wires into the corresponding holes and tighten
the connector screws.
If the connected LED driver cannot be turned off completely from the control interface, an external relay with 12 VDC
coil can be connected to channel 2. Make sure the relay is protected against flyback voltage, e.g. do not use a PCB relay
without the flyback diode. A suitable fixture configuration must be selected in order to control a relay.
CBU-A2D, 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.
Optional 12V relay,
only with 0/1-10V
