accident, it may cause electric shock or endanger human life.
DANGER:There is deadly high voltage between the positive and negative of the PV array.
During installing, ensure that the connection between inverter and PV array is completely
disconnected and set warning marks at the disconnection to avoid reconnecting by accident.
1.1.3 Anti-Static Protection
CAUTION:The static electricity generated by human bodies may damage the
electrostatic-sensitive components on boards. Before touching the sensitive component,
please wear anti-static rings and well connect the other end of the anti-static rings to ground.
1.1.4 Grounding Requirements
WARING:High leakage risk! The inverter must be grounded before electrical connection. The
ground terminal must be connected to earth.
When installing, connect the grounding wire first; when dismantling, the grounding wire
must be removed at last.
It is prohibited to damage the grounding conductor.
The device must be connected with protection earthing permanently. Before operating,
please check the electric connection and ensure the device has been connected to earth
reliably.
1.1.5 Moisture-proof Protection
CAUTION: Moisture incursion may cause the inverter damage!
For normal use of the energy-storage converter, please comply with the following items.
If the atmosphere humidity larger than 95%, please do not open the inverter.
On overcast or rainy or moist condition, avoid opening the panel to maintain or do other
operation.
1.1.6 Safety Warning Label Setting
To avoid irrelevant person close to or misoperate the inverter, during installation or daily
maintenance, please abide by the related standards.
Set warning labels at the front end and back end of the inverter to avoid wrongly close and
even cause accident.
Set warning label board or safety warning area to avoid irrelevant person entering and
cause human injury or device damage.
1.1.7 Electrical Connection
The electrical connection must be done on the basis of the illustration and electrical wiring
principle mentioned in this manual.
WARING:The PV array and grid level, frequency, etc. must accord with the inverter’s
specification.
