4 Preparations for the RS485-Quick Module
4.1 Notes
When the RS485-Quick Module is delivered, the resistor is located in the left spring-type terminal. If
you do not wish to connect the inverter to the end of the RS485 bus, you must remove the resistor, in
order to connect two cables.
4.2 Checking the Country Setting via the Rotary Switches
The factory default for the switches for setting the country configuration is at the 0/0 position.
If you install the RS485-Quick Module in an inverter, which has been in operation, and leave the
switches in the 0 / 0 position, then the country setting in the inverter remains unchanged.
You can change the country setting of the inverter using the rotary switches of the RS485-Quick
Module or a communication device. This overwrites the default network parameters. They cannot be
restored, and must be re-entered via a communication device.
The meaning of the positions of the rotary switches in the RS485-Quick Module are the same as in
the Standard Quick Module. Please read the inverter's installation guide to find the meaning of the
rotary switches.
The inverter changes the country settings and the language immediately after switching on the line
circuit breaker. If an un-programmed switch setting is selected, the inverter issues an error message.
