DANGER!
Opening the Communication Converter
There is danger to life by energized parts.
Before opening the communication converter, it is absolutely necessary to isolate it
from the auxiliary supply voltage at all poles!
• Both devices at the link ends have to be switched on.
• First configure the communication converter CC-1:
• Reconnect the auxiliary supply voltage for the communication converter.
• The system interface (X.21 or G703.1) must be active and connected to the com-
• Change the interface parameters at the 7SD610 (at the device front or via DIGSI):
300
– Disconnect the auxiliary supply voltage from both poles.
– Open the communication converter.
– Set the jumpers to the matching position for the correct interface type and trans-
mission rate; they must be identical with the parameterization of the 7SD610 (ad-
dress 4502 CONNEC. 1 OVER for protection data interface 1, see also Subsec-
tion 2.2.3.1).
– Move the communication converter into test position (jumper X32 in position 2-3).
– Close the communication converter housing.
munication converter. Check this by means of the "device ready"-contact of the
communication converter (continuity at the NO contact).
– If the "device ready"-contact of the communication converter doesn't close,
check the connection between the communication converter and the net (com-
munication device). The communication device must emit the correct transmitter
clock to the communication converter.
