●
Do not touch the terminals or conductors connected to the grid
circuit. ● Read and understand all instructions and safety precautions for
grid connection.
●
Follow all the safety precautions for low voltage power grid.
DANGER! The damaged device or system fault may result in electric
shock or outbreak of a fire!
● Check if there is damage or other dangerous conditions for the device
before operation.
● Check if the external device and circuit connection are in a safe state.
● Make sure the device is in a safe state for operating.
WARNING!
● The inverter can be connected to the grid only if it gets permission from
the local electric power department.
● All electrical installations must be made in accordance with national and
local standards and regulations.
WARNING! Operation by non-professional may result in death or
severe burns.
● Only trained electrically qualified persons are permitted to do
electrical operation on this product.
● During maintenance, it is necessary to ensure that at least two staff
members work in the field; the breakers of AC terminal and DC terminal
must be fully disconnected for at least 10 minutes for internal energy
storage components discharging completely, which should be confirmed
with a voltmeter.
NOTICE! Contact or improper operation on printed circuit board or
other electrostatic sensitive components may result in damage to the
components.
● Avoid unnecessary contacts with circuit boards.
● Comply with electrostatic protection standards, wear an antistatic wrist
strap.
When installing PV arrays during the day, opaque material should be used to cover
the solar battery arrays, otherwise, the solar array will generate high voltage under
sunlight.
The input DC voltage must not exceed 1000 V, and the excessive voltage may result
in damage to the device.
The inverter must be properly transported, stored, assembled, installed, operated
and maintained.
All operations and wiring must be made by qualified personnel only to ensure that all
electrical installations meet the electrical installation standards. In order to ensure
safe operation, the device should be grounded properly and provided with necessary
short circuit protection.
