6 Installing the Communication Assembly
1. Insert the new communication assembly in the Connection Unit.
2. Fasten the communication assembly to the Connection Unit using three of the provided screws.
Tighten the two outer screws first (TX20; torque: 2.3 Nm ± 0.3 Nm (20.35 in-lb ± 2.65 in-lb)).
Then tighten the center screw (TX20; torque: 3.5 Nm ± 0.5 Nm (30.98 in-lb ± 4.43 in-lb)).
3. Plug the ribbon cable connecting the communication
assembly to the Power Unit into the jack on the
communication assembly.
4. Plug the 20-pin connector with the short pin side into the socket terminal strip of the module
slot M2 on the communication assembly.
5. Plug the battery interface module onto the communication assembly:
• Guide the guide pins on the communication assembly through the holes in the battery
interface module.
• Guide the long pin side of the 20-pin connector through the socket terminal strip of the
battery interface module.
• Carefully push the battery interface module down until it audibly snaps into both side
locking tabs of the communication assembly.
6. Fasten the battery interface module to the communication assembly using two of the provided
screws (TX20; torque: 3.5 Nm (30.98 lb)).
7. Insert the ribbon cable connecting the Power Unit to the battery interface module into the jack
on the battery interface module.
8. Insert all connection cables into the respective jacks of the battery interface module.
9. Commission the inverter (see inverter manual). By replacing the communication assembly, the
firmware of the inverter is updated. This process can take several minutes.
10. Insert all plugs into the respective sockets of the communication assembly. Make sure that the
plugs are inserted only after the inverter has been commissioned so that no incorrect serial
number is sent to a possibly existing communication product.
11. Attach the provided label with new identification key (PIC), new registration ID (RID) and new
WLAN password (WPA2-PSK) to right side of the Connection Unit. Please note that the
communication assembly is issued a new RID, PIC and WPA2-PSK due to the replacement.
12. Establish a connection to the user interface and configure the inverter via the installation
assistant (see the inverter manual).
13. If the inverter is registered in Sunny Portal, replace the inverter in Sunny Portal (see installation
manual "Replacement of SMA Devices in Systems with Communication Products" at
www.SMA-Solar.com).
