Explanation of symbols Explanation of DANGER! safety notices Indicates immediate danger. ► If not avoided, death or serious injury will result. WARNING! Indicates a potentially hazardous situation. ► If not avoided, death or serious injury may result. CAUTION! Indicates a situation where damage or injury could occur. ►... - Page 6 In order to minimise the heating up of the inverter, do not expose it to di- rect insolation. Install the inverter in a protected location, e.g. in the vicin- ity of the solar modules or beneath the eaves. Can be used at altitudes of up to 4000 m max.

For this situation, a type A residual-current circuit breaker is generally adequate. However, in certain circumstances, and depending on local factors, the type A residual-current circuit breaker may trip at the wrong time. For this reason, Fronius recommends that a residual-current circuit breaker that is suitable for frequency converters should be used. -
