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.
Note 1 - On MMPxxx-60S models, the INV OUT and INV IN breakers are physically ganged together and
turn ON and OFF as a single breaker.
Note 2 - The INV BYP and INV OUT breakers are interlocked together. Physically turning ON one will turn
OFF the other and vice versa.
