• Close the Hydro unit and reconnect it to Mains Power.
• Reconnect power supply to the KNX bus.
• Follow the instructions on the user's manual for configuring and commissioning the interface. See below how to obtain the user's manual and the ETS database.
NOTE
The cable used for connection of BMS-IFKX0AWR-E to A B bus can be any two-core cabtyre cable, the maximum distance for bus A B is 50 meters, consult the
manual of the Hydro unit for more details.
