:
AC input supplied from local service panel,
AC I/P neutral to earth connection provided externally.
(Usually service panel)
Operation =
On– Line Mode
:
DC input supplied from battery/DC power system
Inverter originated AC, therefore neutral to earth connection provided internally to chassis.
Grounding:
Chassis to Earth Ground connection should be made per customer installation specifications or prevailing safety
jurisdiction authority.
The inverter external safety ground plane is not switched by operation in any mode. Typically - the chassis is
mounted in a rack or a conductor to ground plane is installed.
