Safety Safety Safety Message Types WARNING Safety information important for human safety. Warning is used for indicating potentially hazardous situations that can cause serious injury or death. CAUTION Caution with symbol is used for indicating potentially hazardous situations that can cause minor or moderate injuries. CAUTION Caution without symbol is used for indicating situations that may result in equipment or property damage. WARNING Disconnecting the inverter Before starting work on the inverter, switch off AC at the mains switch and PV using the PV load switch. Ensure that the device cannot be unintentionally reconnected. Use a voltage tester to ensure that the unit is disconnected and voltage free. The inverter can still be charged with very high voltage at hazardous levels even when it is disconnected from AC grid and solar modules. Wait at least 8 minutes following disconnection from grid and PV panels before proceeding. For safe disconnection of DC current, turn off the PV load switch (1). 160AA001.10 NOTE Note is used for indicating highlighted information that should be regarded with attention. General Safety All persons installing and servicing inverters must be: Trained and experienced in general safety rules for work on electrical equipment Familiar with local requirements, rules and regulations for the installation NOTE Before installation Check for damage to equipment and packaging. If in doubt, contact the supplier before commencing installation. CAUTION Installation For optimum safety, follow the steps described in this document. Keep in mind that the inverter has two voltage carrying sides; the PV input and the AC grid. 1 CAUTION Maintenance and modification Only authorised personnel are permitted to modify the inverter. To ensure personal safety, use only original spare parts available from the supplier. If non-original spare parts are used, compliance with CE guidelines in respect of electrical safety, EMC and machine safety is not guaranteed. The temperature of the cooling racks and components inside the inverter can exceed 70ºC. Observe the danger of burn injury. DC voltages up to 1000 V are present in a PV system even when the inverter is disconnected from the AC grid. Faults or inappropriate use may lead to electric arcing. L00410627-02_02
