Errors in parallel configuration will be shown by the LED indicators in the display.
Note:
An error also occurs if the AC OUT-1 of the units are not connected to each other (breakers!).
The "Mains" LED on the Replica unit will keep blinking while the same LED on the Primary unit will be solid on when the MAINS
AC input is accepted. This normal behavior. Likewise LED "GEN" on the Replica unit will keep blinking while the same LED on
the Primary unit will be solid on when the GEN AC input is accepted. This is also normal behavior.
LED 1 is MCU 12/3000-150 and 24/3500-100 only
