3.6.1 System Grounding and Output Neutral to Chassis Ground Bond Switching
WARNING!
•
In "Inverting Mode" (default condition), the Neutral of the AC output of the unit gets
bonded to the metal chassis of the unit through the internal “Neutral to Chassis Switch-
ing Relay” [Relay K4 in Figs 4.1(a) and 4.1(b)].
•
In “Charging Mode”, the internal “Output Neutral to Chassis Switching Relay” discon-
nects the Neutral of the AC output connection from the chassis of the unit. The Neutral
of the AC output connection of the unit will get bonded to the Earth Ground through
the Neutral to Earth Ground bond in the AC Breaker Panel/Load Center supplying Grid
power / AC output connections of the generator.
•
Disabling Neutral to Ground Bond: In some applications, the Output Neutral may be
required to remain isolated from chassis/Ground at all times. For this, automatic Output
Neutral to chassis Ground bond can be disabled by disconnecting the Male/Female Dis-
connect (13, Fig 3.9) located in the AC Wiring Compartment.
•
System grounding, as required by National / Local Electrical Codes / Standards, is the
responsibility of the user / system installer.
For further details please refer to Sections 4.5.1 to 4.5.3.
ATTENTION!
•
En état de défaut, le neutre de la sortie CA de l’unité dans le “Mode de l’onduleur / décharge” obtient lié au
châssis métallique de l’unité à travers la interne “Neutre à châssis relais de commutation”.
Dans “Mode de chargement”, l’interne “Neutre à châssis relais de commutation” déconnecte le neutre de la
connexion de sortie AC du châssis de l’unité. Le neutre de la connexion de sortie CA de l’unité va obtenir lié à la
terre des masses à travers le neutre à la terre liaison au sol dans le centre de panneau de disjoncteurs AC / charge
alimenter Grille / connexions de sortie CA du générateur.
•
Mise à la terre du système, tel que requis par la National / codes électriques locaux / normes, est de la
responsabilité de l’installateur utilisateur / système.
3.6.2 AC Input Considerations – Voltage And Frequency
The EVO unit is designed to accept 120 VAC, 60 Hz / 50 Hz single phase AC power from Grid
or generator. These 120V versions come preset for 60 Hz operation. Frequency can be pro-
grammed at 50 Hz using optional Remote Control EVO-RC (see Appendix A).
3.6.3 Preventing Paralleling of the AC Output
WARNING!
The AC output of the unit cannot be synchronized with another AC source and hence, it is
not suitable for paralleling on the output side. The AC output of the unit should never be
connected directly to an electrical breaker panel / load center which is also fed from another
AC source. Such a connection may result in parallel operation of different power sources and
AC power from the other AC source will be fed back into the unit which will instantly dam-
