To avoid overheating, always make sure the flow of air around the inverter is not
blocked. A minimum clearance of 500mm should be kept between inverters or
objects and 500mm clearance between the bottom of the machine and the ground.
Adequate ventilation must be provided.
NOTE:
Nothing should be stored on or placed against the inverter.
Install vertically with a maximum incline of +/- 5 degrees, exceeding this may cause
output power derating.
