Fan data for DCS880 (H5 ... H8)
Sizes H5 and H6
Sizes H7 and H8
The fan needs an input voltage of 400 VAC at 50 Hz. For 460 VAC/500 VAC use autotransformer (T8).
The fan needs an input voltage of 460 VAC at 60 Hz.

Monitoring the DCS880 power section
The power part of converters size H1 ... H6 is monitored by means of a galvanic isolated PTC thermistor. The PTC
is installed on the heat sink in an isolated configuration. The PTC's resistance and protective effect correspond
to the maximum temperature defined by the type code.
The air entry temperature at the power part of converters size H7 and H8 is monitored by means of a galvanic
isolated PTC thermistor. The sensor measures the power part's radiated heat and any changes in the cooling air
temperature and volume.
The PTC‘s resistance change is proportional to the temperature. It is read and evaluated in the drive's firmware.
If the temperature increases above the preset value, then first a warning and - if the temperature continues to
rise - a fault message is generated. The preset value must not be set more than 5 degrees above the permissible
ambient temperature.
For converter size H7 and H8 the cooling air volume can only be detected indirectly. Thus, additionally a
differential-pressure switch has been installed at the unit's housing. It is always located close to the power
terminals.
The differential-pressure switch compares the pressure inside the drive with the normal air pressure. If the fan
is switched on, the drive's door is closed, no covers have been removed and the pressure switch signals 'cooling
conditions ok' it is possible to release the converter. There is no need to set a specific differential pressure
(recommendation: use the center setting). The differential pressure switch should be connected to the
converter fan acknowledge signal.
