APsystems YC500-A Installation/User Manual
7
APsystems microinverters are designed to only operate when they can
sense power coming from the grid. Even if they are plugged into the PV
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.
Step 1 - Installing the AC branch circuit junction box
A.
Install an appropriate junction box at a suitable location on the
PV racking system (typically at the end of a branch of modules).
B.
Connect the open wire end of the AC branch end cable into the
junction box using an appropriate gland or strain relief fitting.
C.
Wire the conductors: L1- RED; L2 - BLACK; NEUTRAL -WHITE.
NOTE:
Be sure to size the AC wire to account for voltage drop between
the AC branch circuit junction box and the point of utility interconnection.
(See wire size diagram on following page.)
