5.4 Preparing the Cables
Requirement:
☐ The cable requirements are complied with (see Technical Description "RS485 Cabling Plan").
☐ Diameter of the cable when using the cable support sleeve with one hole: at maximum 17 mm
☐ Diameter of the cable when using the cable support sleeve with two holes: at maximum 6.5 mm
Depending on whether the inverter is located at the end or in the middle of the communication bus,
prepare one or two cables as described in the following:
1. Remove 40 mm of the cable sheath at the end of the cable to be connected to the
485 data module.
2. Shorten the cable shield to 15 mm.
3. Fold the surplus cable shield back onto the cable
sheath.
4. Wrap the cable shield with copper foil.
5. Strip the insulation on the three wires each by 6 mm. Two wires for communication must be a
twisted pair.
6. Shorten all other wires flush with the cable sheath.
Disturbance of data transmission due to AC cables
During operation, AC cables generate an electromagnetic field which may induce interference
in plant communication.
• Do not lay the cables of the RS485 communication together with the AC cable.

5.5 Preparing the Cable Gland on the Inverter
In order to prepare the cable gland on the inverter, you have to know whether one or two cables are
to be connected to the 485 data module and whether the multi-function relay in the inverter is to be
used immediately or at a later time.
If you wish to connect one or two cables to the 485 data module and do not want to use the
multi-function relay in the inverter neither immediately nor at a later time, prepare the M25 cable
gland on the inverter for one or two cables.
If you wish to connect two cables to the 485 data module and the multi-function relay in the inverter
is used immediately or at a later time, you must remove the Ethernet socket from the inverter and mount
another M25 cable gland on the inverter.
Preparing the Cable Gland on the Inverter for One or Two Cables
1. Unscrew the swivel nut from the M25 cable gland and push out the sealing plug.
2. If one cable is to be connected, remove the cable support sleeve with one hole from the
M25 cable gland and insert the cable into the one-hole cable support sleeve.
3. If two cables are to be connected, remove the
cable support sleeve with one hole from the M25
cable gland and insert the cables into the supplied
two-hole cable support sleeve.
4. Press the cable support sleeve into the cable gland and lead each cable all the way up to the
sockets on the 485 data module.
5. Screw the swivel nut onto the M25 cable gland.
6. Remove the protective cover of the multi-function relay from the inside of the inverter.
The protective cover is no longer required.

Mounting and Preparing the Supplied Cable Gland on the Inverter
1. Remove the plug from the Ethernet socket.
2. Unscrew the Ethernet socket from the enclosure

3. Insert the supplied M25 cable gland in the
enclosure opening and tighten it from the inside
using the counter nut (torque: 3.5 Nm ± 0.3 Nm).
4. Unscrew the swivel nut from the cable gland and remove the sealing plug from the cable gland.
5. Remove the cable support sleeve with one hole
from the M25 cable gland and insert the cables
into the supplied cable support sleeve with two
holes.
6. Press the cable support sleeve into the cable gland and lead each cable all the way up to the
sockets on the 485 data module.
7. Screw the swivel nut onto the M25 cable gland.
8. Remove the protective cover of the multi-function relay from the inside of the inverter.
The protective cover is no longer required.

5.6 Connecting the Cables to the 485 Data Module
Figure4: Overview of the connection area
Connect each cable to the 485 data module according to the following procedure.
1. Plug one spring-cage connector into each of the
sockets on the 485 data module.
2. If one cable is to be connected, attach the terminator:
• Push the levers of the terminals 2 and 7 of one spring-cage connector upwards.
• Bend the ends of the terminator downwards
and plug the terminator into the open terminals.
• Push the levers back down.
3. Push the levers of the terminals 2, 5 and 7 of one
spring-cage connector upwards.

4. Connect the wire to the terminals of the spring clamp terminal and note down the colour of the
wires. The cables can be allocated to any spring-cage connector.
5. Close the spring clamp terminals.
6. Press each cable with the cable shield into the shield clamp.
8. Tighten the swivel nut of the cable gland.
9. Close and commission the inverter (see inverter installation manual).
10. Connect the cable end to the RS485 bus (for information on the terminal assignment and wiring
in the system, see the Technical Description "RS485 Cabling Plan").

Electric shock due to live cables
If, during inverter operation, an insulated wire (L1, L2 or L3) should become detached from
the AC terminal, there is the risk that the cables of the RS485 communication become live.
Touching the cables can cause fatal electric shock.
• Attach the supplied plastic foil to the module
using the supplied expanding rivet. This
isolates the AC connection area in the
inverter from other terminals.

SMA Solar Technology AG 6 Troubleshooting
Installation Manual 485BRD-10-IA-en-12 19
6 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 "Other" 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 from detecting the
new 485 Data Module.
Corrective measures:
• Prior to performing any work on the inverter,
disconnect the inverter from any voltage sources on
the AC and DC sides (see inverter installation
manual).
Several SMA communication products query data
simultaneously 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).

7 Decommissioning SMA Solar Technology AG

7 Decommissioning
7.1 Disassembling the 485 Data Module
1. Disconnect the inverter from voltage sources on the AC and DC sides and open it
(see the inverter installation manual).
2. Open the spring clamp terminals of the plug at the 485 data module.
3. Remove the wires from the plug.
4. Slightly loosen the swivel nut of the cable gland and remove the cable support sleeve.
5. Remove each cable from the inverter and from the cable support sleeve.
6. Unscrew the screw M4x10 to which the
485 data module is attached to the inverter using a
Torx screwdriver (T 20).
7. Remove the 485 data module from the inverter.
The spacers remain in the inverter.
8. Insert the sealing plug into the cable gland. This ensures that the inverter complies with its degree
of protection.
9. Tighten the swivel nut of the cable gland.
10. Close and commission the inverter (see inverter installation manual).
7.2 Packaging the 485 Data Module for Shipping
• Pack the 485 data module. Use the original packaging or packaging that is suitable for the
weight and size of the 485 data module.
7.3 Disposing of the 485 Data Module
