After all electrical connections from the MP enclosure to the inverters, batteries, AC source, and sub-

panel have been completed, refer to the installation checklist in Section 3.13 of your MP Enclosure

Owner’s Manual (PN: 64-0028) to confi rm proper installation.

3.4 Functional Test

Once you confi rm that the system has been installed properly, you are ready to perform a functional

test. Refer to the functional test procedure in Section 3.14 of your MP Enclosure Owner’s Manual.

WARNING: During the functional test – because the front cover has been removed —

you are exposed to potential dangerous voltages and shock hazards inside the MP en-

closure that may cause damage, injury, or death. If you do not have experience working

with AC and DC voltage circuits, do not attempt this test – use an experienced electrical

installer.

CAUTION:

During the functional test, if any step cannot be verifi ed or is incorrect, stop

and recheck/correct the connections before proceeding to the next step.
