Danger
Attention
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.
Signs on the inverter
There are some symbols which are related to security on the inverter. Please read and
understand the content of the symbols, and then start the installation.
IP65
Operation
Maintenance and repair
EMC / noise level of inverter
Danger
Attention
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!
Some internal components will be very hot when inverter is working. Please wear
protective gloves!
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
.
Danger
Electromagnetic radiation from inverter may be harmful to health!
Please keep away from the inverter more than 20 cm when inverter is working.
1.2 Symbols and signs
There is residual voltage in the inverter! Before open the equipment,
operator should wait for five minutes to ensure the capacitance discharge
completely.
Be careful of high voltage.
Be careful of high temperature.
Conformity with CE.
Point of connection for grounding.
This indicates the allowed temperature range.
This indicates the degree of protection of the equipment according to
IEC standard 70-1 (EN 60529 June 1997).
Positive pole and negative pole of the input voltage (DC).
