Range of application

Warning: During operation, the heat sink can reach a temperature of up to 75 °C.
The "Cold Plate" variant enables installation of the frequency inverter on suitable sur-
faces which have sufficient thermal conductivity to dissipate the heat developing during
the operation of the frequency inverter.
This enables the use of the frequency inverter in the following applications:
Installation in a housing, where a high type of protection is required but the vol-
-
ume of the housing limits thermal compensation.
Use in highly polluted cooling air affecting the function and service life of the fan.
-
Use of several frequency inverters in limited space conditions, e.g. installation of
-
frequency inverters on a liquid-cooled plate (sum cooler).
Direct assembly on (or in) a machine case, with parts of the machine constructions
-
taking over the cooling function.
Note:
8
Do not touch the heat sink during operation.
The heat sink may be hot even some time after the frequency inverter was
switched off.
Frequency inverters with a continuous output >15 kW require an im-
provement of the efficiency of the heat sink by means of suitable fans,
liquid cooling or other measures improving the cooling capacity of the heat
sink.
