Observe all warning messages on the product and in the documentation. Observe all safety information of the battery manufacturer. Before any work is performed, always disconnect the following devices externally: Grid voltage for grid feed-in Internal power supply DC voltage of the battery Additional external voltages, e.g. control signals from a control room Ensure that no disconnected devices can be reconnected. After switching off the inverter, wait at least 15 minutes before opening it to allow the capacitors to discharge completely. Before working on the inverter, make sure that all devices are completely voltage-free. Cover or isolate any adjacent live components. Danger to life from electric shock due to live DC cables DC cables connected to a battery are live. Touching live cables results in death or serious injury due to electric shock. Prior to connecting the DC cables, ensure that the DC cables are voltage-free. Wear suitable personal protective equipment for all work on the product. Danger to life due to high short-circuit current in the battery Despite careful construction, a short circuit may occur in the inverter under fault conditions. In case of a short circuit in the inverter, the connected battery can supply a very high short-circuit current. The resulting electric arc and pressure wave lead to death or serious injuries. Install the inverter in a closed electrical operating area. Always close and lock the inverter. Before entering the operating area, externally disconnect the inverter on the AC and DC side. Only open the inverter when it is completely disconnected and the capacitors are fully discharged. Operating Manual SCS-BE-E7-en-12 11

12 2 Safety SMA Solar Technology AG Danger to life from electric shock due to ground fault If there is a ground fault, system components that are supposedly grounded may in fact be live. Touching incorrectly grounded components results in death or serious injuries from electric shock. Before working on the system, ensure that no ground fault is present. Wear suitable personal protective equipment for all work on the product. Danger to life from electric shock due to damaged product Operating a damaged product can lead to hazardous situations that result in death or serious injuries due to electric shock. Only operate the product when it is in a flawless technical condition and safe to operate. Check the product regularly for visible damage. Make sure that all external safety equipment is freely accessible at all times. Make sure that all safety equipment is in good working order. Wear suitable personal protective equipment for all work on the product. Danger to life from electric shock even if the inverter is disconnected on the AC and DC sides The precharge unit will carry live voltage even if the AC disconnection unit and the DC switchgear are open. Touching live components results in death or serious injury due to electric shock. Do not touch any live components. Switch off the inverter. After switching off the inverter, wait at least 15 minutes before opening it to allow the capacitors to discharge completely. Ensure that no voltage is present. Do not remove protective covers.
