SHORE POWER CONNECTIONS (60 HERn)
If the installer connects· shore power to the vessel's AC cir-
cuit, this must be done by means of the Shore Power Transfer
'Switch. Set the transfer switch shown in the diagrams to the
OFF position. 'This switch prevents simultaneous connection
of shore power to generator output.
A CAUTION: Damage to the generator can result if
utility shore power and generator output are connected
at the same time. This type of generator damage is not
covered under the warranty; it is the Installer's responsi-
bility to make sure all AC connections are correct
