3-5. AC Safety Grounding：
During the AC wiring installation, AC input and output ground wires are
connected to the inverter. The AC input ground wire must be connected to
the incoming ground from AC utility source.
The AC output ground wire should go to the grounding point for your loads
( for example, a distribution panel ground bus ).
3-5-1. Neutral Grounding (GFCI’S)：
3-5-1-1. 120V models：The neutral conductor of the AC output circuit
of the Inverter is automatically connected to the safety ground
during inverter operation. This conforms to National
Electrical Code requirements that separately derived from AC
sources (such as inverters and generators) which have their
neutral conductors tied to ground in the same way as the
neutral conductors from the utility tied to ground at the AC
breaker panel. For models configured with a transfer relay,
while AC utility power is present and the Inverter is in bypass
mode, this connection (the neutral of the Inverter’s AC output
to input safety ground) is not present so that the utility neutral
is only connected to ground at your breaker panel, as required.
Other types may fail to operate properly when connected to
this inverter equipment.
The risk of electronic shock. Use only pass and Seymour
type 2091-W, ground fault circuit-interrupter receptacles.
WARNING!
3-5-1-2. 230V models：There is no connection made inside the
Inverter from either the line or neutral conductor to safety
ground.
