The connections must be tight against bare metal. Use star washers to penetrate paint and
corrosion.
As the Equipment Grounding Bus Bar (G3) in the DC Panel is bonded to the
Grounding Electrode (GE), the chassis of the EVO / DC side will be bonded to Earth
Ground.
WARNING!
For application of EVO on a boat, the size of the Equipment Grounding Conductor (EGC) from the
Grounding Terminal on the EVO (G2) to the boat’s system Ground, should be the same size as the
battery cable.
ATTENTION!
Si vous utilisez le EVO sur un bateau, la taille du conducteur de terre de l’équipement «EGC» pour le côté de terre CC
devrait être de la même taille que le câble négatif de la batterie.
3.14 AC SIDE GROUNDING (PLEASE SEE FIG 3.12)
• The AC Input Grounds {GEN GND (8), GRID GND (5)} and AC Ouput Ground {OUTPUT GND
(11)}, are internally bonded to the chassis of the inverter (G1)
• The Equipment Grounding Conductors (part of the Grid/Generator input wiring) from Bus
Bars (G3) for the Equipment Grounding Conductors in the Grid and Generator Input Panels
are connected to the AC input Ground terminals in {GRID GND (5), GEN GND (8)}.
• The AC output Ground terminal of the EVO{OUTPUT GND (11)} is connected to the Equip-
ment Grounding Conductor of the AC output wire which then connects to the Bus Bar (G3)
for the Equipment Grounding Conductors of the AC Distribution Panel.
• The Bus Bar (G3) for Equipment Grounding Conductors of the AC Distribution Panel is con-
nected to the Bus Bar for the Equipment Grounding Conductors (G3) of the Grid/Generator
Input Panel, which in turn is connected to the Ground Rod or the Grounding Electrode (GE).
Thus, in keeping with the NEC requirements, the AC Grounds of EVO and the AC
Distribution Panel will be bonded to the Earth Ground only at one single point at the
Grid/Generator Panel feeding the EVO.
3.14.1 OUTPUT NEUTRAL TO CHASSIS GROUND BOND SWITCHING
As required by NEC and UL specification 458, AUTOMATIC Output Neutral to Chassis Ground
bond switching arrangement has been provided in these units through “Output Neutral to
Chassis Ground Bond Switching Relay” [K4 in Figs 4.1(a) and 4.1(b)] to switch bonding of the
Output Neutral Connector of the Inverter Charger as follows:
• When operating as an inverter, the current carrying conductor of the Inverter Section that is
connected to the Output Neutral connector of the Inverter Charger is bonded to the metal
chassis of the inverter 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 the inverter is in turn bonded 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 current carrying conductor of the Inverter Section will become the Grounded
Conductor (GC) or the Neutral of the Inverter Section.
