To use the rapid shutdown feature,the inverter communication board firmware(CPU)must be: • Version 2.0700 or higher,if the CPU version is 2.Oxxx • Version 3.0700 or higher,if the CPU version is 3.Oxxx ® To check the inverter CPU version: 1 Verify that the inverter has been activated using the activation card supplied with the inverter. 2 Press the LCD light buffo_n short presses until the screen below is reached. 1D : MY i1111 Y Mr ii D S P 1 / 2 : x . x x x x / x . x x x x C P U 0 0 0 2 . 0 7 0 0 C o u n t r y : X X X X X 3 Check the CPU version number.If lower than 2.0700,upgrade the inverter software as described below;otherwise proceed to"Power Optimizer Pairing". 10, To upgrade the inverter software: Use the supplied SO card adapter or the micro-SD card,which can be removed from the adapter,according to the activation card slot on your inverter communication board,labeled E G110 . 7 Verity that the AC breaker connected to the inverter is OFF. 2 Open the inverter cover's six Allen screws and carefully pull the cover horizontally before lowering it, as described In its manual. 3 Insert the card into the card slot on the communication board. If the communication board has an SD card slot,use the supplied SO card adapter.If there is a micro-SD card slot,remove the micro-SD card from the adaptor and insert it. 4 Close the inverter cover and turn the AC on.If upgrade is required(as described above),it starts automatically. 5 Wait for the message"Done"to be displayed on the LCD. 6 Verify the correct version as described above. 7 Remove the card from the inverter and keep it for additional kit installations. Power Optimizer Pairing Pairing at this stage will reprogram the power optimizers to perform rapid shutdown. 1 Verity that the ON/OFF switch at the bottom of the inverter is OFF. 2 Turn ON the AC breaker and the Safety Switch. 3 Perform Pairing as described in Step 2:Pairing,of Chapter 5:Commissioning of the SolorEdge Installation Guide.
