6.4 DC Side Connection
Danger
！
Before connecting PV array and inverter, the PV array should be covered with
opaque materials and the DC switch should be off, otherwise, the PV array may
generate high voltage, and cause casualty. Non-professional person cannot operate.
Warning
！
Before connecting PV array to the inverter, ensure the impedance between PV array with
ground is not less than 1Mohm.
