5 Mechanical Mounting
5.1 Requirements for Mounting
Make sure there is no electrical connection before installation.
•In order to avoid electric shock or other injury, make sure that holes will
not be drilled over any electricity or plumbing installations.
•Always follow the instructions when moving and positioning the inverter.
•Improper operation may cause injuries or serious wounds. In the case
of poor ventilation, the system performance may compromise.
5.1.1 Location Requirements
Select an optimal mounting location for safe operation, long service life and
expected performance. During the installation and operation process, please
the inverter in don't install the inverter where people may touch its casing
and radiator, because these parts will be very hot during operation.
5.1.2 Environment Requirements
The inverter must be installed in a ventilated environment to ensure good
heat dissipation. Make sure the installation site meets the following
conditions:
•
Not in areas where highly ammable materials are stored.
• Not in potential explosive areas.
• Not in the cool air directly.
• Not near the television antenna or antenna cable.
• Not higher than altitude of about 4000m above sea level.
• Not in environment of precipitation or humidity (＞95%).
• Under good ventilation condition.
• The ambient temperature in the range of -30℃ to +60℃.
• The slope of the wall should be within ±5°.
• The wall hanging the inverter should meet conditions below:
• The wall must be solid enough to bear the weight of the inverter.
• Do not install the inverter on a wall made of gypsum boards or similar
materials with weak sound insulation to avoid noise disturbance in a
residential area.

5.1.3 Angle and Space Requirements
Never install the inverter horizontally, or with a forward tilt or with a backward
tilt or even with upside down. The horizontal installation can result in damage
to the inverter. Install the inverter upright or at a maximum back tilt of 15
degrees to facilitate heat dissipation.
