may result if appropriate precautions are not taken.
CAUTION! Indicates a situation where damage or injury could occur. If it is not
avoided, minor injury and/or damage to property may result.
NOTE! Indicates a risk of flawed results and possible damage to the equipment.
IMPORTANT! Indicates tips for correct operation and other particularly useful information.
It does not indicate a potentially damaging or dangerous situation.
If you see any of the symbols depicted in the "Safety rules" chapter, special care is required.
The inverter is suitable for installation indoors.
IP 44
INDOOR / OUTDOOR
max.
3000 m
INDOOR
OUTDOOR
> 3000 m
Do not install the indoor device outside without an inlet air attachment or
an outlet air unit.
With an inlet air attachment and outlet air unit, the inverter is suitable for
installation outdoors.
Can be used at altitudes of up to 3000 m
IMPORTANT! The inverter must not be installed or used at altitudes
above 3000 m.

Do not install the inverter:
- in areas where ammonia, corrosive vapours, acids or salts are present
(e.g. fertiliser stores, ventilation openings from cattle sheds, chemical plants, tanneries, etc.)
As the inverter generates low levels of noise at certain times, it should
not be installed close to living areas.
Do not install the inverter:
- in places where there is an increased risk of damage from farm animals (horses, cattle, sheep, pigs, etc.)
- in stables or adjoining areas
- in storage areas for hay, straw, chaff, animal feed, fertilisers, etc.
Do not install the inverter:
- in places and environments subject to heavy build-up of dust
- in places and environments in which a heavy build-up of dust containing conductive particles (e.g. iron chips) is likely
Do not install the inverter:
- in greenhouses
- in storage or processing areas for fruit, vegetables or winegrowing
products
- in places used to prepare grain, green fodder or animal feeds
