Installation
• The “INPUT GND” Terminal (
8A, Fig 3.9
) of the AC Input / Output Terminal Block in EVO™ gets connected to the
Grounded Bus Bar (
G-B
) in the Grid Electrical Panel (
AC PANEL 1
) through the grounding wire of AC input connection
• The Grounded Bus Bar (
G-B
) in the Grid Electrical Panel (
AC PANEL 1
) is bonded to Earth Ground through the
Grounding Electrode (
GE
) / “Ground Rod” of the premises
b) AC Output Grounding:
The metal chassis of the AC load(s) gets connected to the Grounding Electrode (
GE
) /
“Ground Rod” of the premises as follows:
• The metal chassis of the AC load(s) connected to the EVO™ is connected to the Grounded Bus Bar (
G-B
) of
the Electrical Sub Panel for EVO™ Output
• Grounded Bus Bar (
G-B
) of the Electrical Sub Panel for EVO™ Output (
AC PANEL 2
) is connected to metal chassis
of EVO™ through the “OUTPUT GND” Terminal (
8B, Fig 3.9
) of the AC Input / Output Terminal Block in EVO™.
• The metal chassis of EVO™ is connected to the “INPUT GND” Terminal (
8A, Fig 3.9
) of the AC Input / Output
Terminal Block in EVO™
• The “INPUT GND” Terminal (
8A, Fig 3.9
) of the AC Input / Output Terminal Block in EVO™ gets connected to the
Grounded Bus Bar (
G-B
) in the Grid Electrical Panel (
AC PANEL 1
) through the grounding wire of AC input connection
• The Grounded Bus Bar (
G-B

3.14.3 Switching Of Bonding Of Output Neutral To Chassis Ground
As required by NEC, automatic switching of bonding between the Output Neutral and Chassis Ground has been provided in
EVO™ through “Output Neutral and Chassis Ground Bond Switching Relay” (
RY-5 in Fig 4.1
). Switching is carried as follows:
• When operating as an inverter, the current carrying conductor of the Inverter Section that is connected to the
Output Neutral terminal of the EVO™ is bonded to the metal chassis of EVO™ by the “Output Neutral to Chassis
Ground Bond Switching Relay” (
RY-5 in Fig 4.1
). As the metal chassis of EVO™ is in turn bonded to the Earth
Ground (
in shore installations
), this current carrying conductor of the Inverter Section (
connected to the Output
Neutral Terminal
) will become the Grounded Conductor (
GC
) or the Neutral of the Inverter Section.
• When in Charging Mode, the Neutral conductor of Grid power or Generator will be connected to the Output
Neutral terminal of EVO™. At the same time, the “Output Neutral to Chassis Ground Bond Switching Relay” (
RY-5
in Fig 4.1
) will unbond (
disconnect
) the Output Neutral connector of EVO™ from the metal chassis of EVO™. This
will ensure that the Grounded Conductor (
GC
) i.e. the Neutral of the Grid power is bonded to the Earth Ground at
one single point at the location of the AC Power Distribution System of the Marina / RV Park / Shore Power.
• Disabling Neutral to Ground Bond:
In some applications, the Output Neutral of EVO™ may be required to
remain isolated from the chassis/Ground at all times. For this, automatic Ouput Neutral to Chassis Ground bond can
be disabled by disconnecting the Insulated Male/Female Quick Disconnect located in the AC wiring compartment.
For more details, refer to Sections 4.5.2(D) and 4.5.2(E).
