Fibre Link Connection
The fibre optic cable is connected through the ST400 connectors. To connect the
ELO E171, the transmitter of the remote converter must be connected to the receiver of
the local ELO E171 and the remote receiver must be connected to the local transmitter
(fibres cross).
Both converters must be set to the right data range and data format. The rotating switch
on the top converter case is used to it.
3.3
Power Connection
The external supply has to have the output voltage of 12-24V and it is connected via
DC+ and DC- clamps. The supply take off is c.200 mA. If the supply is on operation the
indicator RUN switches on.
The converter contains two isolated zones. The RS-485 circuits are separated from the
other ones and supplied via the internal isolated DC/DC converter. If it is necessary to
keep this separation the external power supply must be isolated from the signal grounds
of all RS-485 partners.
