Together with the BNA device, a supply pack with installation material is delivered containing the required connectors for power and field bus.

5.1Power 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.
