Ground Connection
It is important that all stations connected to the BACnet network are connected to the same ground potential.
The ground connection must have low HF (high frequency) impedance. This can be achieved by connecting a
large surface area of the cabinet to ground, for example by mounting the TR200 series on a conductive rear
plate. Particularly when there are long distances between the stations in a BACnet network, it may be necessary
to use additional potential equalizing cables, connecting the individual stations to the same ground potential.
The use of repeaters with galvanic isolation or fiber optic can improve the EMC performance and reduce ground
loop current.
