and E1h–E4h
iC7 Series Frequency Converters and VLT® FC Series Drives
1 Overview
1.1 Description
This IGBT module replacement kit contains all components required to replace 1 IGBT module or 1 brake IGBT module. For the num-
ber of IGBTs installed in the frequency converter, see
SPARE PARTS COMPATIBILITY
Danfoss recommends replacement of all IGBT modules or all brake IGBT modules when 1 or more modules fail.
-
For best results, replace modules with parts from the same lot number.
