![]() ![]() The solar modules must not be grounded at either the positive or negative pole. The inverter is designed to be connected and used exclusively in conjunction with ungrounded solar modules. Refer to the device Installation Instructions for the tightening torques to be used at the relevant terminal connections. To reduce the hazard potential to a minimum, perform all installation and connection work carefully according to the instructions and regulations. Observe the manufacturer's connection, installation and operating instructions at all times. Note! After an arc has been detected, the entire photovoltaic system must be checked for possible damage before resetting the inverter. ![]() Fronius accepts no liability for fires that can occur despite the presence of the integrated arc detection/extinguishing system (e.g. Note! Fronius will not accept any costs associated with production downtimes, installer costs, etc., that may arise as the result of a detected arc and its consequences. Using fastening screws, always screw the inverter firmly to the mounting bracket to the torque specified in the Operating Instructions.Įnsure that the fastening screws are tight before starting the inverter! Take note of the safety instructions, Operating Instructions and any local connection regulations Tighten all grounding terminals (PE / GND), including free ones, to the torque specified in the operating instructionsĬheck cables for damage and verify that they are laid correctly ![]() ![]() Tighten all terminals to the torque specified in the operating instructions Observe the following when connecting AC and DC cables: These can cause heat damage, which in turn may lead to fires. Poor or unprofessional installation can cause overheating of cables and terminal connections and result in arcs. This may result in damage to inverters and other live photovoltaic system components. Danger due to poor or unprofessional installation. ![]()
