Surrounding air temperature is a temperature measured at a measure-
ment position in an enclosure. Ambient temperature is a temperature
outside an enclosure.
The specific acceptable ambient temperature depends on the overload capacity of the individual inverter.
2.9 m/s
1 - 2
for operation
for storage
These temperatures are allowed for a short period only e.g. during shipping.
With circuit board coating, IP55 compatible models: 95% RH or less (non-condensing),
Indoors (free from corrosive or flammable gas, oil mist, dust and dirt)
Maximum 1000 m above sea level with no limitations. For altitudes above 1000 m derate
the inverter capacity by 3% for every additional 500 m.
Maximum installation altitude: 2500 m (with 91% of the inverter rated capacity)
