5.3 Connecting the 485 Data Module
To achieve a good signal quality, observe the cable recommendation (see Technical Description
"RS485 Cabling Plan").
Procedure:
To connect the 485 Data Module, perform the following work steps in the prescribed sequence.
The exact procedure is described in the following sections.
• Prepare the cable
• Connect the cable to the 485 Data Module
Preparing the Cable
1. Remove 40 mm of the cable sheath at the end of the cable which is to be connected to the
485 Data Module.
2. Shorten the cable shield to 15 mm.
3. Fold the surplus cable shield back over the cable
sheath.
4. Wrap the cable shield in conductive adhesive foil.
5. Strip off the insulation of the three insulated conductors by 6 mm. The two insulated conductors
used for communication must be a twisted pair.
6. Shorten all other conductors flush with the cable sheath.
Interference in data transmission due to AC cables
During operation, AC cables generate an electromagnetic field which may induce interference
in plant communication.
• Lay the RS485 communication cables using suitable fastening material and with a
minimum clearance of 50 mm to the AC cables.

7 Troubleshooting SMA Solar Technology AG
20 485i-Module-IA-en-19 Installation Manual
7 Troubleshooting
Problem Cause and corrective measures
The emergency channel list "Emergncy"
or "EmgncyXX" is displayed in the
communication product (e. g. Sunny
WebBox, Sunny Explorer).
The inverter is displayed with the device
class "Others" in Sunny Portal.
The 485 Data Module has been installed in an inverter
without first disconnecting the inverter on the AC and DC
sides. This prevents the inverter detecting the new
485 Data Module.
Corrective measures:
• Prior to performing any work on the inverter,
disconnect the inverter from all voltage sources on
the AC and DC sides (see inverter installation
manual).
Several SMA communication products are
simultaneously querying data from the devices via
Bluetooth (e.g. Sunny Explorer, Sunny Beam with
Bluetooth) and RS485 communication (e.g. Sunny
WebBox).
This can cause data congestion if a lot of data is
transmitted simultaneously. If this state lasts for more than
five minutes, the inverter carries out a reset of the
485 Data Module. Due to the data congestion, the
inverter cannot detect the 485 Data Module after the
reset.
Corrective measures:
• Wait until the inverter restarts the next morning,
then the inverter will detect the 485 Data Module.
or
Disconnect the inverter from voltage sources on the
AC and DC sides and recommission it (see the
inverter installation manual).
