Section 8 |
- Do not bond (connect) the Neutral and the Ground in the Sub-Panel
- When Utility power is available, the 2 poles of the Transfer Switch will connect the
Hot and Neutral of the Utility power to the Hot and Neutral in the Sub-Panel. The
Neutral of the Sub-Panel will be bonded to the Earth Ground through the Main Utility
Supply Panel. As the Neutral of the inverter will be isolated from the Neutral of the
utility power, the Neutral of the GfCI output will not be bonded to the Earth Ground
and the GfCI will not trip
- When the Utility power fails or is interrupted, the Hot and the Neutral of the GfCI will
be connected to the Hot and Neutral of the Sub-Panel. As the Neutral is not bonded
to Earth Ground in the Sub-Panel, the GfCI in the inverter will not trip.
8.6 GROUNDING TO EARTH OR TO OTHER DESIGNATED GROUND
for safety, ground the metal chassis of the inverter to the Earth Ground or to the other
designated ground (for example, in a mobile RV, the metal frame of the RV is normally
designated as the negative DC ground). A Grounding Terminal (5, fig 6.1) has been pro-
vided for grounding the metal chassis of the inverter to the appropriate ground.
When using the inverter in a building, connect a 10 mm
copper wire from the above Grounding Terminal to the Earth Ground connection
( a connection that connects to the Ground Rod or to the water pipe or to another
connection that is solidly bonded to the Earth Ground ). The connections must be tight
against bare metal. Use star washers to penetrate paint and corrosion.
When using the inverter in a mobile RV, connect a 10 mm
stranded copper wire from the above equipment grounding lug to the appropriate
ground bus of the RV (usually the vehicle chassis or a dedicated DC ground bus). The
connections must be tight against bare metal. Use star washers to penetrate paint and
corrosion.
8.7 INTERNAL NEUTRAL TO CHASSIS GROUND BOND
The Neutral slots of the 2 NEMA5-15R outlets (1, fig 6.1) are internally bonded to the
metal chassis of the inverter for protection against Ground fault.
In case of mobile applications where it is not possible to ground the metal chassis of
the inverter, please ensure that the AC loads are connected through a 2-pole, 3 Wire
Grounding type of cord with a NEMA5-15P, 3-Pin Plug. This will provide protection
against electric shock in case of Ground fault in the load (Line voltage leaking to the
metal chassis of the load). fault current will flow through the Grounding Conductor to
the chassis of the inverter and onward to the Neutral of the inverter (through internal
Neutral to the chassis Ground bond) and will shut down the inverter due to overload /
short circuit protection of the inverter.
8.8 REDUCING ELECTROMAGNETIC INTERFERENCE (EMI)
Please comply with recommendations given in Section 3.2.
