Installation

AC Sources

The inverter has a single set of AC terminals which are intended to connect to a single AC source.
It cannot be directly wired to more than one AC source at the same time. If multiple sources are
used, it is usually required to have a selector switch that changes from one to the next. The switch should
be the "break before make" type which disconnects from one source before contacting another. It must
also be a double-pole type which switches both the hot and neutral wires.
In mobile or marine installations, the AC source neutral and ground conductors are expected to be
mechanically bonded.
Figure 13 AC Sources
In Figure 13, the shore power and generator are disconnected. The internal transfer relay automatically
bonds the inverter's output neutral and ground connections as shown. This function can be disabled.
Figure 14 AC Sources and Transfer Relay
When either AC source is connected and accepted, the internal transfer relay switches to transfer the AC
source power to the loads. The internal transfer relay also opens the internal neutral-ground bond.
The AC Source bond is used instead. Figure 14 shows the shore power connected and shows the
shore power bond.
See the Operator's Manual for the inverter's criteria for accepting an AC source.
