Forced ventilation

Upgrading the system (continued) Please take further details from the chapter „LocalNet“ of the installation and service manual.

Forced ventilation The FRONIUS IG unit is equipped with a temperature and rotation controlled 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 rotation 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.
