5.1 Power Connection
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).
For the power connection, the 2 pole Phoenix
connector is required (included). If an off-the-shelf
power supply is used, cut off the original connector
at the end of the cable. Then strip the two cable
ends and insert each cable end into the openings of
the 2 pole Phoenix connector. Fasten them with a
screwdriver.
The polarity (+/-) of the 2 pole Phoenix power
connector for DC power supplies is don’t care.
