Does the TeSys T LTME Expansion Module require the connection of the LV1/LV2/LV3 phases to operate the logic inputs?

No, There is no need to connect main power on L1/L2/L3 on the LTME terminals to operate and use the Logical inputs.  The LTME expansion modules are powered by the LTMR controller via a connector cable.
