Termination of serial
communication. See Earthing of
screened/armoured control
cables.
This terminal is not normally to be
used.
RS 485 interface, serial

communication. Where the VLT
frequency converter is
connected to a bus, switches 2
and 3 (switches 1- 4 - see next
page) must be closed on the first
and the last VLT frequency
converter. On the remaining VLT
frequency converters, switches 2
and 3 must be open. The factory
setting is closed (position on).
