YC500A Installation Procedures
APsystems Microinverters are designed to only operate when they can sense power coming
from the grid. Even if they are plugged into the solar array, they will not turn themselves on
until they can read power from the grid.
WARNING:
Do NOT connect APsystems Microinverters to the utility grid or
energize the AC circuit until you have completed all of the installation
procedures as described in the following sections.
