4. Plug the RS485-Quick Module into the designated holes on the bracket until it snaps into place.
5. Push the RS485-Quick Module carefully upwards.
6. Check that the RS485-Quick Module is securely in
place.
☑ The RS485-Quick Module is mounted. Should
you not have made these settings yet, you can
set the installation country, the display
language, and the Bluetooth communication
(see page 15).
7. Close the DC-Disconnect (see section 5.8 „Closing
the SMA DC-Disconnect and Commissioning the

5.6 Connecting the RS485 cable to the RS485-Quick Module
1. Flip up the flap of the RS485-Quick Module and lift
the cover until it snaps into place.
2. When connecting 2 cables (inverter in the middle of
the RS485 bus), remove the resistor on the left
spring-type terminal.
In this guide it is assumed that the inverter is not connected to an end of the RS485 bus.
Should the inverter be connected to an end of the RS485 bus, perform the following steps
for one cable only.
If one cable is connected (inverter at the end of the RS485 bus) leave the resistor
connected to the spring-type terminal of the RS485-Quick Module.. If the resistor is not
correctly connected, see section 4.4 „Terminating the RS485 Bus“ (page 18).
