2.2 Explanations of Symbols
Do not dispose of this device with the normal domestic waste.
Without transformer
This inverter does not use transformer for the isolation function.
CE mark
The inverter complies with the requirements of the applicable
CE guidelines.
Refer to manual before service.

must be carried out by qualified personnel only.
Beware of hot surface
The inverter’s housing may reach uncomfortably hot 60°C (140°F) under high
power operation. Do not touch the inverter enclosure when operation.
Residual power discharge
Do not open the inverter cover until 5 minutes after disconnection both
DC and AC power supply.
Important notes
Read all instructions carefully. Failure to follow these instructions,
warnings and precautions may lead to device malfunction or damage.

from grid. Please make sure below requirements are followed before connecting
AC cable to the inverter.
· The AC (grid) voltage must not exceed inverter’s range
· The phase-line from AC distribution box are correctly connected
· Use the AC plugs in the accessory
· The surge protector should be equipped between grid and inverter
· Disconnect the AC (grid) switch during wiring
