SMA Solar Technology AG 6 Connection • 40 mmPeel cable sheath. Make sure that no pieces of cable are dropped into the inverter. • Strip off the conductor insulation by 6 mm. • On the 2-pole terminal block, unlock the required terminal positions using a suitable tool ( ) and plug the conductors of the connection cable into these terminal positions ( ).
7 Configuration SMA Solar Technology AG Configuration Configuring the Anemometer or Energy Meter You must configure the S0 input of the module depending on the signal source used (anemometer or energy meter). To ensure that correct measured values are displayed, you must set the number of pulses per second.
SMA Solar Technology AG 7 Configuration Configuring the Temperature Sensor If temperature sensors for module temperature and/or ambient temperature are connected, the inverter automatically detects the type of temperature sensors connected and activates the measurement mode. You can configure the display of the temperature display on the start page of the user interface in the event of an error (e.g.
7 Configuration SMA Solar Technology AG 4. In the context menu, select [Starting the installation assistant]. 5. Select [Save and next] until you reach the Irradiation temperature step. 6. Under Module temperature and External temperature, select the required setting value for the temperature display in the event of an error.
