To avoid serious injury orequipment damage, observe the information in the list,especially when installing large units.CAUTIONThe frequency converter is cooled with air circulation.To protect the unit from overheating, ensure that theambient temperature does not exceed the maximum ratedtemperature. If the ambient temperature is in the range of45 °C - 55 °C, derating of the frequency converter isrelevant, see 3.5.5 Derating for Ambient Temperature.If derating for ambient temperature is not taken intoaccount, the service life of the frequency converter isreduced.5.2 Pre-installation5.2.1 Planning the Installation SiteNOTETo avoid extra work during and after installation, it isimportant to plan the installation of the frequencyconverter in advance.Select the best possible operation site by considering thefollowing:• Ambient operating temperature• Installation method• How to cool the unit• Position of the frequency converter• Cable routing• Ensure the power source supplies the correctvoltage and necessary current• Ensure that the motor current rating is within themaximum current from the frequency converter• If the frequency converter is without built-infuses, ensure that the external fuses are ratedcorrectly.How to Install VLT® AQUA Drive FC 202 Design GuideMG20Z102 - VLT® is a registered Danfoss trademark 915 5
