°C.Whenrackmountingtheunits,thefollowingfactsmustbeconsidered:

 Theadmissibleambienttemperaturerangeforoperationofthesemiconductorcomponentsis0°Cto+70°C

(commercialtemperaturerangeforoperation).

 Theairflowthroughtheinstallationmustprovidethattheoutgoingairisalwayscoolerthan70°C.

 Averageheatincreaseofthecoolingairshall

beabout20K,allowingforanadditionalmaximum10Kincreaseat

thehotcomponents.

 Inordertodissipate1kWwiththisadmissibleaverageheatincrease,anairflowof2.65m³/minisrequired.

Example:ArackdissipatingP=800Wrequiresanairflowof

0.8*2.65m³/minwhichcorrespondsto2.12

m³/min.

 Ifthecoolingfunctionoftheinstallationmustbemonitored(e.g.forfanfailureorilluminationwithspotlamps),

theoutgoingairtemperaturemustbemeasureddirectlyabovethemodulesatseveralplaceswithin
