6. Apply power from an external AC source (utility or AC generator) to the AC Input Terminals.
a. Connect an AC voltmeter to the AC Input Terminals and verify that the AC voltage from
the external AC source is present. Connect the AC voltmeter to the AC Output Terminals
and check that the external AC source power is passing thru the INV BYP (Inverter Bypass)
breaker by verifying the AC source voltage present earlier is also present on the AC Output
Terminals.
7. Turn ON the INV OUT

and INV IN breaker(s) in the MMP enclosure.
a. Ensure the AC source power is passing thru the INV IN (Inverter Input) breaker by verifying
the AC source voltage present earlier (in Step 6) is also present on the AC Output Terminals.
8. After all the AC voltage checks pass, install the front cover and manually open and close all
circuit breakers, checking for correct alignment and free operation.
If all the steps pass, the MMP enclosure is ready for use. If the any of the steps fails, refer to
Installation section and recheck your wiring connections and/or refer to the Troubleshooting section
for your inverter.
