It mainly introduce the safety instruction when install and operate the . 20~33KTL-G2
1.1 Safety instructions
Note
Symbols and signs
It mainly introduce the safety symbols on . 20~33KTL-G2
20~33KTL-G2 must be installed according to the national and local grid standard and law.
Read and understand the instruction of this manual ,and be familiar with relevant safety
symbols in the paragraph, then start to install and debug the equipment.According to the
national and state requirements, before connect the grid ,you must get power department
permission, and perform the operation only by qualified electrical engineer.Before installing
and maintaining the equipment, you should cut off the high voltage application of PV array.
You can also open the switch of Solar Array Combiner to cut off the high voltage. Otherwise,
serious injury may be caused.
Qualified persons
Assembly situation requirements
Please install and start inverter according to the following sections. Put the inverter in
appropriate bearing capacity objects(such as wall and components and so on), to ensure that
inverter vertical placed. Choose suitable place for installing electrical equipment. And assure
enough fire exit space, convenience for maintenance. Maintain proper ventilation, and
ensure that have the enough air cooling cycle.
Transport requirements
Electric connection
Please comply with all the current electrical regulations about accident prevention in dealing
with the current inverter.
Before the electrical connection, make sure to use opaque material to cover the
PV modules or to disconnect PV array DC switch. Exposure to the sun, PV array
will produce a dangerous voltage!
Danger
Warning
Attention
All installation accomplished only by professional electrical engineer!
Only get permission by the local power department and complete all electrical
connection by professional electrical engineer then connect inverter into grid!
must be trained;
Completely read the manual operation and understand relevant matters.
Electrical installation and maintenance shall be conducted by qualified
electrician and shall comply with national wiring rules.

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).
