User manual
Operation
Touching the power grid or the terminal of equipment may lead to die of electric
shock or fire!
Don't touch the terminal or conductor which connect to the power circuit;
Pay attention to anything about grid connection and security document.
Danger
Some internal components will be very hot when inverter is working. Please wear
protective gloves!
Attention
Maintenance and repair
Disconnected with the PV components array and electricity grid before any
repair work;
After turn off AC breaker and DC switch for 5 minutes later, the maintenance
or repair of the inverter can be carried out!
Danger
Inverter should work again after removing any faults. If you need any repair
work, please contact with the local authorized service center;
Can't open the internal components of inverter without authorized. DASS
Tech Co., Ltd does not take any responsibility for the losses from that.
Attention
EMC / noise level of inverter
Electromagnetic compatibility (EMC) refers to that one electrical equipment functions in a
given electromagnetic environment without any trouble or error, and impose no
unacceptable effect upon the environment. Therefore, EMC represents the quality characters
of electrical equipment.
The inherent noise-immune character: immunity to internal electrical noise.
External noise immunity: immunity to electromagnetic noise in external system.
Noise emission level: influence of electromagnetic emission upon environment.
Electromagnetic radiation from inverter may be harmful to health!
Please keep away from the inverter more than 20 cm when inverter is working.
