Page 9: Important Safety Instructions
SMA Solar Technology AG 2 Safety IMPORTANT SAFETY INSTRUCTIONS Keep the manual for future reference. This section contains safety information that must be observed at all times when working. The product has been designed and tested in accordance with international safety requirements. As with all electrical or electronical devices, there are residual risks despite careful construction. - Page 10 2 Safety SMA Solar Technology AG DANGER Danger to life due to electric shock in case of overvoltages and if surge protection is missing Overvoltages (e. g. in the event of a flash of lightning) can be further conducted into the building and to other connected devices in the same network via the network cables or other data cables if there is no surge protection.
- Page 11 SMA Solar Technology AG 2 Safety WARNING Danger to life due to electric shock from destruction of the measuring device due to overvoltage Overvoltage can damage a measuring device and result in voltage being present in the enclosure of the measuring device. Touching the live enclosure of the measuring device results in death or lethal injuries due to electric shock.

PV array can be detected at an early stage. SMA Speedwire The product is equipped with SMA Speedwire as standard. SMA Speedwire is a type of communication based on the Ethernet standard. SMA Speedwire is designed for a data transfer rate of 100 Mbps and enables optimum communication between Speedwire devices within systems. - Page 16 The product is equipped with a Modbus interface. The Modbus interface is deactivated by default and must be configured as needed. The Modbus interface of the supported SMA products is designed for industrial use – via SCADA systems, for example – and has the following tasks: •...
- Page 17 The SMA Sensor Module has different interfaces for connecting various sensors (i.e. temperature sensor, irradiation sensor, anemometer or energy meter). The SMA Sensor Module converts the signals of the connected sensors and transmits them to the inverter. The SMA Sensor Module can be retrofitted.
- Page 18 With SMA ShadeFix, inverters use the best possible energy supply from the PV modules at all times to increase yields in shaded systems. SMA ShadeFix is enabled by default. The time interval of SMA ShadeFix is usually six minutes. This means that the inverter determines the optimum operating point every six minutes.
