iC7 Series Liquid-cooled L Filter OF7Z5

1 Overview

L Filter

1.1

The L Filter is used together with an LC Filter to create an LCL input filter for AFE or grid converter modules in applications where

regenerative or low-harmonic functionality is required.

There are 3 electrical sizes of the filter: 400 A, 1000 A, and 1640 A.

Page 8 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.
Page 9 Installation Guide | iC7 Series Liquid-cooled L Filter OF7Z5 Cooling Requirements These glycols already include corrosion inhibitors. Do not add any other inhibitor. Do not mix different glycol qualities because there can be harmful chemical interactions. The glycol concentration of the coolant must be 25–55% by volume, according to the specified ambient temperature. Higher concentration reduces cooling capacity.
