If a fault occurs in the rectifier unit, a fault message is output via the
connecting contacts of the signaling relay.
When the 24 V supply is connected, the relay closes as long as no fault
is present.
In the event of a fault, the lock of the line contactor is opened, the
contactor drops out and the drives coast down.
The USS bus is used for the internal communication of the units and
only has to be connected if it is required.
The digital inputs and outputs and the analog input and output have to
be assigned according to the requirements of the drives.
CAUTION: Terminal X101.1 may not be connected with the
external 24V supply.
The X320 interface of the rectifier unit serves only for permanently
connecting the user-friendly OP1S operator control panel and for
connection to the on-line inverters.
Please refer to the relevant operating instructions for the applicable
measures and notes for correct operation.
The serial interface is used to connect the user-friendly OP1S operator
control panel or a PC. It can be operated either according to the RS232
or the RS485 protocol.
Please refer to the relevant operating instructions for the applicable
measures and notes for correct operation.
When a capacitor module is used, the terminals for precharging the
capacitors must be connected.
The use of an output contactor is purposeful if a motor needs to be
electrically isolated from the converter/inverter with the DC link
charged.
Use of a line filter is necessary if the radio interference voltages
generated by the converters or rectifier units need to be reduced.
The Siemens cables described in the catalog should be used for
connecting the converter and the motor to each other.
The use of output reactors, output filters, sinusoidal and dv/dt filters is
not permissible.
