Fronius IG 15 - Manual (Page 50)

42
The FRONIUS IG unit is equipped with a temperature and rotation con-
trolled air circulator which provides for the following features:
- smaller heat sinks - more compact housing
- components are better cooled - efficiency increases / longer life
- least possible energy consumption / noise level, due to rotation control
and ball bearing support
- should there not be sufficient heat discharge in spite of maximum rotati-
on of the ventilator (for example no adequate heat transfer away from
the control panels) the power will be derated for auto-protection of the
FRONIUS IG unit.
- derating the power reduces the output of the FRONIUS IG unit for a
short period sufficient to ensure that the temperature will not exceed
the admissible parameter.
- your FRONIUS IG unit will remain ready for operation as long as
possible without any interruption.
- Even if the FRONIUS IG is frequently used at full load the fan can
be expected to last approx. 20 years.
