MATCHING SCR/DIODE MODULES
If all 3 SCR/diode modules installed in a frequency converter are not the same type and manufacturer, the frequency converter
can malfunction.
-
Check that the replacement module matches the existing modules. If not, replace all 3 SCR/diode modules.
-
If replacing multiple SCR/diode modules, verify that all kit numbers match.
