operation, the heat sink can reach a temperature of up to 75 °C.
Do not touch the heat sink during operation.
he heat sink may be hot even some time after the frequency inverter was
switched off.
The “Cold Plate” variant enables installation of the frequency inverter on suitable sur-
faces which have sufficient thermal conductivity to dissipate the heat developin
durin
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.
. installation o
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: 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 hea
sink.
