- The firmware does not support the type of power section at hand
- In addition, IndraDrive C / IndraDrive M as of MPx-18: The hardware of the power section is outdated. The HCS02, HCS03, HCS04, HMS and HMD power sections are only supported by control section Cxx02.x if they were manufactured in 2007 or later [see indication ‘FD’ on the name plate of the power section (example: 07W49 means year 2007, week 49)]. Older hardware of these device types is no longer supported.
