3 How to Install
3.1 Connecting the Bus Line
Terminate the bus line at both ends of each segment. A
mismatch of impedance may result in reflections on the
line resulting in corrupt data transmission.
The Profibus Option Card contains a suitable termination.
To activate the termination, turn on
Switch 1
on the
Profibus converter option. By default, the switch is turned
off.
NOTICE
Notice that pin numbers are colour
coded on the Profibus connector.
Unlike the VLT
®
5000, the FC 302 Profibus connectors are
colour-coded to avoid swapping the bus wires.
