APS YC500A-MIW Installation/User Manual
10
WARNING:
Insure that all AC and DC wiring is correct. Check that
none of the AC and DC wires are pinched or damaged. Be sure that
all junction boxes are properly closed.
Step 4 - Ground the System
NOTE:
If you already use grounding washers (WEEB) to ground the
Microinverter chassis to the PV module racking as described in Step
2C, skip this step.
Each APS Microinverter comes with a ground clamp that can
accommodate a single #6 awg strand and #4 awg solid conductor.
Check your local electrical code for grounding conductor sizing
requirements. Connect the grounding electrode conductor to the
microinverter ground clamp.
NOTE:
The AC output neutral is not bonded to ground inside the
microinverter.
