Electrical safety notice of durable solar pump controller !
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.
• 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.
