Installation Guide iC7 Series Liquid-cooled DC Filter OF7D1 1 Overview DC Filter A DC/DC converter requires a DC filter between the DC source and the converter for current control and the ability to boost voltage. The filter also smoothens the current and voltage waveform, making them suitable for most DC sources or loads.

General Information on Cooling NOTICE For more detailed information about the requirements for liquid-cooling, see the iC7 Series Liquid-cooled System Modules Design Guide. The product is cooled with liquid. The liquid circulation of the drive is usually connected to a heat exchanger (liquid-to-liquid or liquid-to- air) that cools down the liquid circulating in the cooling elements.
