INSTALLATION
Steps
:
1. Mount the PowerCombi MasterBus Interface to any flat
surface. The PowerCombi MasterBus Interface comes
with a DIN rail mount option. Alternatively, use the two
mounting holes (1).
2. Insert the RJ11 cable (included) and connect to the
remote port (REMO) of the PowerCombi (2).
3. Adding the PowerCombi MasterBus Interface to the
MasterBus network:
-
Disconnect a MasterBus cable (3a) or Terminator
(3b) from the closest MasterBus device and connect
it to the PowerCombi MasterBus Interface.
-
Connect the new MasterBus cable (included) to the
other MasterBus device and then connect to the
PowerCombi MasterBus Interface.
4. A flashing LED (4) indicates that the MasterBus
communication is working.
5. When the PowerCombi MasterBus Interface is
connected, open MasterAdjust on a Windows laptop or
notebook connected to the MasterBus network via a
MasterBus USB interface. MasterAdjust is available as
free to download software on the Mastervolt website:
www.mastervolt.com.
