4-1.Use environment
(1) The ambient temperature is -10 50 C. When the temperature is over 40 degrees, the
reduction rate is 3% at 1 degrees centigrade.
It is not recommended to use the frequency converter in the environment above 50 C.
(2) Preventing electromagnetic interference and keeping away from interference sources.
(3) Prevent the invasion of water droplets, steam, dust, dust, cotton floss and fine metal
powder.
(4) Prevent the invasion of oil, salt and corrosive gases.
(5) Avoid vibration. The maximum amplitude does not exceed 5.8m/s (0.6g)
(6) Avoid high temperature, humidity and rainless dripping. Relative humidity is less than
90% RH and condensation is not allowed. In the presence of corrosive gases, the maximum relative
humidity should not exceed 60%.
(7) Altitude
(8) It is prohibited to use in dangerous environments of flammability, flammability, explosive
gases, liquids or solids.
4-2.Installation direction and space
PI500-S series inverter according to different power rating, the requirements of around
installation reserve space is different, specifically as shown below:

Figure 4-1 PI500-S Series Each power level installation space requirement
PI500-S Series Solar inverter heat radiator circulated from bottom to top, when more than one
inverter work together, usually mounted side by side. In the case of the need to install them by
upper and lower rows, due to the heat of the lower inverters rising to the upper equipment, fault
maybe caused, heat insulation deflector and other objects to be installed.
