4. Installation
WARNING!
Shock Hazard. Before proceeding further, carefully
check to see if the Inverter is connected to the batteries,
and every electrical sources wiring is disconnected.
Do not connect output terminals of the Inverter
to incoming AC source.
4-1 AC Safety Grounding:
During the AC wiring installation, AC input and output grounding are
connected to the inverter. The AC input grounding must connect to the
incoming grounding of your AC utility sources and the AC output grounding
should go to the grounding point for your loads. (for example, a distribution
panel ground bus ).
Neutral Grounding (GFCI):
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 derived AC
sources separately (such as inverter and generators) have their neutral
conductors tied to ground in the same way that the neutral conductor from
the utility is tied to ground at the AC breaker panel.
For models configured with a transfer relay, while AC utility powers
presenting and the Inverter is in bypass mode, this connection
(neutral of the Inverter's AC output to input safety ground ) is not
presented so that the utility neutral is only connected to ground at your
breaker panel,as required.
4-2 Ground Fault Circuit Interrupters (GFCI):
Recreational Vehicles Installations (for North American approvals) will require
GFCI protection. All branch circuits connected to the AC output hard wire
should be GFCI protected. Additional electrical codes may require GFCI
protection of certain receptacles in residential installations.
While the pure sine wave output of the Inverter is equivalent to the
waveform provided by utilities, compliance with UL standards requires us to
test and recommend specific GFCI.
