iC7 Series Liquid-cooled LC Filter OF7Z1

1 Overview

LC Filter

1.1

The LC Filter is used as an input filter with AFE or grid converter modules in applications where regenerative or low-harmonic

functionality is required. The LC Filter reduces switching noise, and ensures correct power quality and minimal interruption to the grid.

There are 2 electrical sizes of the filter: LC10L (380 A) and LC12L (760 A). Both are available in EMC categories C3 and C4.

Page 6 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.

The internal thread size is G1/2. The depth of the threads is 13 mm (0.51 in).
Page 8 Install the LC Filter between the AFE and the AC grid. If the AFE has parallel power units, install a separate LC Filter for each of them. See 4.11 Wiring Diagrams. Cable Requirements For information about recommended cable types and required cable sizes, see the iC7 Series Liquid-cooled System Modules Design Guide. | Danfoss Drives Oy © 2024.11 AN447722908366en-000201 / 172K1110B...
Page 9 The front-end modules in the drive system must be equipped with fast-acting AC fuses to limit the damage of the drive system. Install AC fuses at the input terminals of the LC Filter. The AC fuses are not included in the LC Filter delivery. For the recommended fuse types and required fuse sizes, see the iC7 Series Liquid- cooled System Modules Design Guide.
