NOTICE
The inverters are designed and tested strictly to comply with related safety rules. Read and
follow all the safety instructions and cautions before any operations. Improper operation might
cause personal injury or property damage as the inverters are electrical equipment.
DANGER
• Connect the DC input cables using the included PV connectors or terminals. Severe
damage might happen if other types of PV connectors or terminals are used, which is
beyond the manufacturer’s liability.
• Do not connect the inverter to PV string that requires positiver or negative grounding.
WARNING
• Ensure the component frames and the bracket system are securely grounded.
• Ensure the DC cables are connected tightly, securely and correctly.
• Measure the DC cables with a multimeter to avoid reverse polarity connection. Also, the
voltage should be under the permissible range.
• Do not connect one PV string to more than one inverter at the same time. Otherwise, it
may damage the inverter.
• Ensure that the positive or negative poles of the PV string do not short-circuit to the
ground. Otherwise, severe damage might happen, which is beyond the manufacturer’s
liability.
