WARNING! • Do not disassemble any parts of the product which are not mentioned in the installation guide. It contains no user-serviceable parts. See warranty for instructions on obtaining service. Attempting to service the device by yourself may result in a risk of electric shock or fire and will void your warranty.
Page 9
CAUTION! Danger of burn injuries due to hot enclosure parts! • During operation, the enclosure may become hot. CAUTION! Risk of electric shock from energy stored in the capacitor. • Never operate on the inverter couplers, the Mains cables, battery cables, and PV cables when power is applied.
Battery safety instructions A1-HYB-G2 Series inverter should be coupled with a high voltage battery. The battery must comply with UL 1973 and must be SolaX certified. As accumulator batteries may contain potential electric shock and short-circuit current dangers, to avoid accidents that might be thus resulted, the following warnings should be observed during battery replacement: •...
