2 Safety

Working Environment
– Pay attention to all safety regulations relating to the handling of electrical equipment, which
apply in your area of work.
– Ensure that children and other people are kept well clear of potential sources of danger
during mounting and maintenance of the device.
Electrical Safety
– The plugs must not be altered in any way; only install cable connections as is described in
this manual. Unaltered plugs and appropriate plug sockets reduce the risk of an electric shock.
– Keep the device out of the rain and clear of sources of water during installation and
operation. If water gets into the radio module, the risk of electric shock is increased and the device may be damaged.
Personal Safety
– Take the necessary precautions to keep unauthorized persons clear of the device and
prevent it from being accidentally started up during mounting.
Radiation
– Possible health risks associated with the effect of radiation. Do not remain within a distance
of less than 20 cm from the antenna for long periods of time.
Service
– Only allow your Wireless Set to be repaired by qualified specialists and only using original
spare parts.

3 The Wireless-Set485-01

3.1 Applications

With the Wireless-Set485-01, you can extend the RS485 communication bus of your PV plant using radio transmission. The transmission path should be seen as a cable substitute and establishes a point­to-point connection. SMA distinguishes between the communication device side and the inverter side. On the communication device side, there is the communication device (Sunny WebBox, Sunny Boy Control) and possibly other communication bus devices. On the inverter side, all the other communication bus devices can be connected. Communication bus devices include the inverter or the Sunny SensorBox.

6.1 Applications

The Wireless-Set485-02 extends your Wireless-Set485-01 by a further transmission path. As with the Wireless-Set485-01, SMA distinguishes between the communication device side and the inverter side. The communication device side of the Wireless Set 495-02 corresponds to the communication device side of the Wireless-Set485-01. The power is supplied by the Power Injector, labeled "Datalogger", which has already been supplied with the Wireless-Set485-01. The functions overview and identification are the same as those of the Wireless-Set485-01 (see chapter 3 ).

1. Remove around 4 cm of the cable sheath at the end of the communication cable.
2. Shorten the shielding.
3. Connect the leads to the clamps (Data+, Data--, GND, +12V) on the plug for the radio module.
4. Note the connection and lead color:
Data+ _____________________ Data-- _____________________ GND _____________________ +12V _____________________
5. Plug the plug into the radio module of the Wireless­Set485-02.
6. Plug the termination plug of the Wireless-Set485-01 into the radio module of the Wireless-Set485-02.
Set2
Radio Module of the Wireless-Set485-01 (Set 1)
7. Remove around 4 cm of the cable sheath at the end of the communication cable.
8. Fold back the shielding and wrap it with conductive adhesive foil.
9. Connect the leads to the clamps (Data+, Data-, GND, +12V) on the plug and to the radio module (see point 4).
10. Plug the plug into the radio module of the Wireless­Set485-01.
You have successfully connected the radio module to the radio module of the Wireless-Set485-01.
Set1
Affixing the Shield Clamp
Press the foil-wrapped shielding of the two RS485 cables on the radio module of the Wireless-Set485-01 into the shield clamp.

SMA Solar Technology AG Commissioning

7 Commissioning

Do not connect the power supply unit until the mounting and cabling of the Wireless-Set485-01 / Wireless-Set485-02 is complete.
Connecting the RS485 Power Injector to the Power Supply
1. Plug the plug of the power supply unit into the RS485 Power Injector.
2. Plug the power supply unit of the RS485 Power Injector into a 230 V / 110 V plug socket.
The green Power LED on the RS485 Power Injector will light up.

8 Decommissioning

1. Unplug the power supply units of the RS485 Power Injectors.
2. Remove the RS485 cable connections.
3. Disassemble the antenna, radio module and RS485 Power Injector.

Troubleshooting SMA Solar Technology AG

9 Troubleshooting

9.1 RS485 communication unit is not working

If the LED on the radio module shows no activity, carry out the following checks in sequence.
Radio Module
1. Check whether the radio modules are switched on (see 7 "Commissioning" (page27)).
2. Check the correspondence of the radio module pair and the radio channel of the Wireless Set. See chapter 3.4 "Identification" (page10). The "pair" and the "channel" must correspond for both radio modules in a set.
RS485 Power Injector
3. Check the power supply to the RS485 Power Injector (see 7 "Commissioning" (page27)).
4. Check whether the RS485 Power Injector is installed on the co rrect side (communication device or inverter side) - see chapter 3.4 "Identification" (page10).
5. Check the length of the cable connecting the RS485 Power Injector to the radio module. The cable length must not exceed 30 m. This also applies to all the cabling of the Wireless-Set485­01 and 485-02 on the communication device side.
Electrical Connection
6. Check the plug connections and cable connections of all devices, see chapter 5 "Electrical Connection" (page16).
7. Check the termination of the communication bus, see chapter 5 "Electrical Connection" (page16).
Antenna
8. Check that the opposing antenna is visible and remove any objects which may be causing disturbance (e.g. vehicles). Change the position of the antenna if necessary.
If the measures described here are insufficient to solve the problem, contact our Service Line (see chapter 12 "Contact" (page32)).

Maintenance and Cleaning SMA Solar Technology AG

10 Maintenance and Cleaning

10.1 Maintenance

Carry out regular visual checks of the antenna, the radio module, the RS485 Power Injector and the connected cables, to detect any external damage or dirt. If the functioning or safety is impaired, the damaged device or cable should be replaced by a qualified specialist.

10.2 Cleaning

NOTICE!
Damage to the Wireless-Set485-01 or Wireless-Set485-02 devices caused during cleaning.
The Wireless-Set485-01 and Wireless-Set485-02 devices are not waterproof. No water must be allowed to get into the devices.
• Unplug the RS485 Power Injector power plug.
• Clean the Wireless-Set485-01 or Wireless-Set485-02 with a slightly damp cloth only.
Clean the devices with a soft, slightly damp cloth. Extremely dirty devices can be cleaned with a mild, non-abrasive and non-corrosive cleaning agent.
If dirt gets into the plug or the terminal strip, clean these with a cleaning agent for circuit boards or electrical devices.

10.3 Disposal

At the end of their service life, dispose of the Wireless-Set485-01 or Wireless-Set485-02 in accordance with the disposal regulations for electronic scrap applicable at the installation site at that time. Alternatively, return it to SMA with shipping paid by sender, and labeled "FOR DISPOSAL".
