SMA SOLAR TECHNOLOGYSUNNY BOYForewordSMA Solar Technology AG2.5 Safety instructionsDANGER!Danger to life due to high voltages in the Sunny Boy!• All work on the Sunny Boy must be carried out by a qualified electrician. Highvoltages are present in the device.• Work is to be carried out on the Sunny Boy only once the AC and DC voltages havebeen disconnected from the Sunny Boy, and once it has been ensured that thecapacitors have been discharged.• The Sunny Boy must be disconnected from the grid and precautions must be taken toprevent the grid being accidentally reconnected. In addition, the connections to thePV generator must be disconnected.• After isolating the AC and DC voltage, you must wait approximately 15 minutes forthe capacitors in the Sunny Boy to discharge. Only then is it safe to open the unit byremoving the cover and make sure that no voltage is present in the device.WARNING!High efficiency!Check the system design using the Sunny Design tool(www.SMA.de/Sunny Design) or by calling the SunnyBoy Service Line. Overvoltages lead to the destructionof the Sunny Boy.WARNING!Electrostatic charge!When working on the Sunny Boy and handling its assemblies, remember to observe allESD safety regulations. Electronic components are susceptible to electrostatic charge.Discharge any electrostatic charge by touching the grounded housing before handling anyelectronic component.8 SB25_30-IEN083212 Installation Guide
SMA Solar Technology AGForewordWARNING!Risk of injury due to the heavy weight of the Sunny Boy!The Sunny Boy weighs approximately 32 kg. Min. two people must carry the unit or asuitable transport trolley must be used. Safety boots must be worn.CAUTION!Danger of burn injuries due to hot housing parts!• Do not touch the housing of the Sunny Boy during operation.NOTICE!Foreign objects or water entering the Sunny Boy can damage the device!• If the Electronic Solar Switch has been pulled out, the Sunny Boy only has aprotection rating of IP21. Thus it is no longer protected against water seepage andforeign objects.Grounding the PV generator!Comply with the local requirements for grounding the modules and the PV generator. SMASolar Technology recommends connecting and grounding the generator frame and otherelectricity conducting surfaces in such a way that there is continuous conduction andgrounding in order to achieve maximum protection for systems and persons.Installation Guide SB25_30-IEN083212 9
