2 Safety SMA Solar Technology AG 2 Safety IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS 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 7 SMA Solar Technology AG 2 Safety DANGER Danger to life due to electric shock in case of a ground fault If there is a ground fault, components that are supposedly grounded may in fact be live and components that are normally ungrounded may be grounded.
- Page 8 2 Safety SMA Solar Technology AG WARNING Danger to life due to electric shock when the internal power supply is switched off After switching off the internal power supply at the load-break switch -Q62, lethal voltages are still present in the cables to load-break switch -Q62 Only after the power path has been enabled are all cables of the internal power supply de-energized.

4 Power-Generating Unit Protection Test SMA Solar Technology AG 4 Power-Generating Unit Protection Test The power-generating unit protection test is a fundamental part of PV system certification. For existing systems the protection test is part of the certificate, for new systems it is part of the declaration of conformity. The power-generating unit protection test helps grid operators and the certifying body to understand the proper parameterization and function of the protection concept. -
