half a year.
Don't store the inverter without package.
1.3 Installation
DANGER
1.
The DC switch and breaker of the inverter must be cut off and the inverter shell must be reliably grounded
before any operation is conducted inside the inverter.
2.
The inverter must be grounded canonically and the dimension of grounding conductor must conform to the
requirements of security specifications to ensure the personal safety.
3.
Don't place explosive and inflammable substances around the inverter.
WARNING
1.
The installation environment of the inverter must have good ventilation and heat dissipation, the inverter
can
’
t expose to the sunlight directly.
2.
It's advised to fix the inverter by four personals to avoid mechanical injury. Please take safety measures to
prevent injury during installation.
3.
Liquid, dust or debris must be prevented from entering the inverter during installation and maintenance as
conducting liquid and debris may cause short circuit inside the inverter, thus damaging the equipment.
4.
Please ensure the installing torque of power cable is proper during the wiring of external cables and
inverter, excessive torque will damage the screw, and too small torque will increase the contact resistance
and result in overheating.
5.
The terminal of the power cable connected with the inverter must comply with national standard as
substandard terminal or disqualified construction may lead to overheating of the power cable and outbreak
of fire in severe cases.
6.
Installation place must meet the operation environment requirements. Please refer to "2.10 Ambient
Requirements" for detailed information.
1.4 Operation
DANGER
1.
During the operation of inverter, the cabinet door of inverter needs to be locked to avoid electric shock and
other personnel injuries, which can also prevent salinity, water, dust or other conducting materials in the air
from entering into inverter.
2.
Please keep the surrounding environment of operating inverter non-corrosive.
3.
Don't place explosive and inflammable substances within two meters from the inverter.
4.
Don't touch the internal board, components, cables and terminal blocks of inverter during the powering on.
5.
When there are faults or abnormal smell or sound, turn off the DC switch and open the breaker of AC side
immediately.
WARNING
1.
Power on the inverter only after completing the installation and properly connecting the cables.
2.
Do not conduct any insulation resistance test or high-voltage resistance test for inverter, because wrong
test may cause damages to inverter.
3.
Cut off wiring between inverter and external equipment when conducting insulation and voltage resistance
test for external equipment.
