Electrical safety notice of durable water pump converter!
 
Ignoring the following instructions can cause physical injury, or damage to the equipment.
Only qualified electricians are allowed to install and maintain the inverter!
• Never work on the photovoltaic generator or inverter and its input/output cables when the inverter is connected to the power system or to the photovoltaic generator.
• Before working inside the inverter cabinet, switch off or isolate the auxiliary voltage supply to the inverter.
• Isolate the inverter from the photovoltaic generator using the safety switch of the generator or by using the isolation switch.
• Do not touch the input of the isolation switch that has high DC voltage.
• After disconnecting the inverter from the power system or the DC input supply, wait for at least 5 minutes to discharge the intermediate circuit capacitors.
• Measure with a multimeter to ensure that no voltage is present.
• Impedance should be at least 1 MΩ.
• Voltage should be close to 0 V between inverter phases L1, L2, L3 and frame, and between module terminals Brk+ and Brk-.
• Do not make any insulation or voltage withstand tests on the inverter or on the inverter modules.
Note:
• The DC connection terminals Brk+ and Brk- carry a dangerous DC voltage of up to 800 V.
• Depending on the external and internal wiring, dangerous voltages of 115 V to 230 V may be present at the different terminals in the auxiliary circuit.
• At the inverter input, the photovoltaic cells generate DC voltage even at low intensity of sunlight.
