For the BNA device an external power supply with
the following specification is required:
18-24V AC (50...60Hz) or 18-24V DC.
Power consumption of the BNA device is 5VA
(connected via 10BaseT, twisted pair) or 12VA
(connected via AUI, 10Base5).

connector is required (included). If an off-the-shelf
power supply is used, cut off the original connector

ends and insert each cable end into the openings of
the 2 pole Phoenix connector. Fasten them with a
screwdriver.
