Ambient operating conditions
Min. operating = -10°C
Max. operating = 50°C
If the inverter is to be installed at an altitude > 1000m, derating will be required.
(Refer to MM420 Reference Manual)
Do not drop the inverter or expose to sudden shock.
Do not install the inverter in an area where it is likely to be exposed to constant vibration.
Do not install the inverter near sources of electromagnetic radiation.
Do not install the inverter in an environment, which contains atmospheric pollutants such as dust, corrosive gases, etc.
Take care to site the inverter away from potential water hazards, e.g. do not install the inverter beneath pipes that are subject to condensation. Avoid installing the inverter where excessive humidity and condensation may occur. IP54 and IP56 units offer additional protection.
Mount the inverter vertically to ensure optimum cooling. Additional ventilation may be required for horizontal mounting.
Ensure that the inverter’s air vents are not obstructed. Allow 100 mm clearance above and below the inverter.
