• When operating as an inverter, the current carrying conductor of the Inverter Section that is
connected to the Output Neutral terminal of EVO is bonded to the metal chassis of EVO by the
"Output Neutral to Chassis Ground bond Switching relay" [K4 in figs 4.1(a) and 4.1(b)]. As the
metal chassis of EVO is in turn bonded to the Earth Ground (in shore installations) or to the rV
Ground (chassis of the rV) or to the boat Ground (DC Negative Grounding bus bar and the Main
AC Grounding bus bar are tied together in a boat and this is called the "boat Ground"), this cur-
rent carrying conductor of the Inverter Section (connected to the output terminal) will become
the Grounded Conductor (GC) or the Neutral of the Inverter Section.
• When in Charging Mode, the Neutral conductor of the Grid power/Generator will be con-
nected to the Output Neutral terminal of EVO. At the same time, the "Output Neutral to
Chassis Ground bond Switching relay" [K4 in figs 4.1(a) and 4.1(b)] will unbond (discon-
nect) 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/Generator 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
Output Neutral to Ground bond can be disabled by disconnecting the Male/female Quick
Disconnect located in the AC wiring compartment. [Please see (i) 13, fig 3.9 and (ii) "QD' in
figs 4.1(a) and 4.1(b)]

cAution!
The Neutral Terminals of Grid and Generator Inputs are internally bonded to the metal chassis of
EVO (The Neutral Output Terminal of EVO is bonded to the metal chassis of EVO or kept isolated
from the metal chassis of EVO through Neutral to Chassis Ground bond Switching relay; See Section
4.5.1). hence, use PLAIN brEAKEr and NOT GfCI / GfCI protected breaker on the circuit feeding
AC power from Grid / Generator to the EVO. If GfCI / GfCI protected breaker is used on the Grid /
Generator circuit feeding the EVO, the GfCI will trip due to splitting of Neutral return Currents.
!
Attention!
Les bornes neutre de l'entrée du réseau et du générateur sont liés à l'interne au châssis métallique de l'EVO (la borne
neutre de la sortie de l'EVO est lié au châssis métallique de l'EVO ou est maintenus isolés du châssis métallique de l'EVO
a travers du lien neutre à châssis du relais de commutation; Voir la section 4,5,1). Par conséquent, utiliser « PLAIN
BREAKER » et non « GFCI / GFCI PROTECTED BREAKER» sur le circuit d'alimentation CA du réseau / générateur à l'EVO.
Si le disjoncteur protégé GFCI / GFCI est utilisé sur le circuit de réseau / générateur alimentant l'EVO, le disjoncteur se
déclenchera en raison de fractionnement des courants de retour au neutre.
