Do we have to use the LTM-E extension module as a mandatory part with LTMR protection relay ?

The LTM R controller, either alone or connected to an LTM E expansion module, can be operated with or without a user interface device.
In any configuration, the LTM R controller can be configured to perform monitoring, fault management, motor protection and control functions.

All user interface devices require an independent power source
