GENERAL INFO

Instead of sending and receiving information to and from frequency converters through I/O, you can

connect them to a fieldbus.

Vacon NX frequency converters can be connected to the RS-485 bus using a fieldbus board. The

converter can then be controlled, monitored and programmed from the host system.

BACnet is also known by names Direct Digital Control Systems and Building Management Systems.

BACnet technology is used mostly in building automation, lightning control, air conditioning and in

heating automation. The protocol is an upper level net protocol suitable for large building

automation projects.

BACnet stands for Building Automation and Control Network. BACnet is a true non-propriatery open

protocol communication standard conceived by a consortium of building management, system users

and manufacturers.

If you purchase your BACnet option board separately, please note that it shall be installed in slot E

on the control board of the frequency converter.

WARNING!

Internal components and circuit boards are at high potential when the frequency

converter is connected to the power source. This voltage is extremely dangerous

and may cause death or severe injury if you come into contact with it.
