as follows:
Symbol Symbol description
This symbol explains items that need to be paid attention to when being
operated.
This symbol is briefed on some useful information.
This symbol briefs on: If does not operate on request, may cause death,
severely injured or serious property loss.
!
Note
!
(1) Forbid to connect U, V, W output end to AC power supply, otherwise cause
the complete damage of the inverter.
(2) Don't make P- and P + short-circuited, otherwise cause the inverter to be
damaged.
(3) The inverter is forbidden to install on the flammables, otherwise have danger
of fire.
(4) Don't install it in the environment with explosive gas, otherwise have danger
of causing explosion.
(5) After connecting main loop, should carry on insulating treatment to bare
wiring end, otherwise have danger of getting an electric shock.
(6) If being connected to the power supply, don't operate the inverter with moist
handsotherwise have danger of getting an electric shock.
(7) The ground terminal of the inverter must be grounded well.
(8) Inverter being connected to power supply, please don't open cover and carry
onwiring, can connect the wire or check only after closing power for 10 minutes.
(9) Only qualified personnel may carry on wiring and forbid leaving over any
conductive thing in machine, otherwise have danger of getting an electric shock
or causing damage of the inverter.
(10) Inverter stored for over 2 years, should be stepped up gradually with voltage
regulator first while having the electricity, otherwise have danger of getting
electric shock and explosion.
