Ingeteam Inc Installation manual

2.1.3. Ambient temperature

The Ingecon Sun Lite U inverters are designed to operate between -4 ºF (-20 ºC) and 158 ºF (70 ºC).
®
To operate at nominal power, the maximum ambient temperature must not be above 113 ºF (45 ºC).

2.1.4. Atmospheric conditions

The surrounding air must be clean and the relative humidity must not exceed 50% at more than 104 ºF (40 ºC).
Higher percentages of relative humidity, up to 95%, are tolerable at temperatures below 86 ºF (30 ºC).
It should be taken into account that, occasionally, moderate condensation may occur as a result of temperature varia-
tions. For this reason, in addition to the inverter's own protection system, the equipment should also be monitored
when operating at sites whose atmospheric conditions may be outside of those described above.

2.1.5. Contamination rating

The inverters have been designed for a grade 3 contamination rating.

2.1.6. Noise contamination

When operating, the inverters emit a slight buzzing sound.
Do not locate the inverters in an occupied room or on lightweight supports which could amplify this noise. The
mounting surface must be firm and adequate for the weight of the equipment.

2.1.7. Ventilation

There must be a 11.81 inches (30 cm) clearance over the inverters and 7.87 inches (20 cm) at the sides and base.
This is to ensure that the inverter cooling system operates correctly.
