8.5 AC SIDE CONNECTIONS
WARNING! Preventing Paralleling of the AC Output
1. The AC output of the inverter cannot be synchronized with another AC
source and hence, it is not suitable for paralleling. The AC output of the in-
vertershouldneverbeconnecteddirectlytoanelectricalbreakerpanel/load
center which is also fed from the utility power/ generator. Such a connection
will result in parallel operation and AC power from the utility / generator will
befedbackintotheinverterwhichwillinstantlydamagetheoutputsection
of the inverter and may also pose a fire and safety hazard. If an electrical
breakerpanel/loadcenterisbeingfedfromtheutilitypower/generator
andtheinverterisrequiredtofeedthispanelasbackuppowersource,the
AC power from the utility power/ generator and the inverter should first be
fed to a manual selector switch / Automatic Transfer Switch and the output
of the manual selector switch / Automatic Transfer Switch should be con-
nectedtotheelectricalbreakerpanel/loadcenter.
2. To prevent possibility of paralleling and severe damage to the inverter, never
use a simple jumper cable with a male plug on both ends to connect the AC
output of the inverter to a handy wall receptacle in the home / RV.
