caution!
1. Do not connect the ac output of the unit to ac distribution wiring where the neutral is
bonded to Ground. the inverter will see this as abnormal condition of Ground fault and
will shut down.
2. the ac output of this unit can not be used in parallel with another ac power Source –

Limiting electro-magnetic interference (emi)
This unit contains internal switching devices that generate conducted and radiated elec-
tromagnetic interference (eMI). The eMI is unintentional and cannot be entirely elimi-
nated. The magnitude of eMI is, however, limited by circuit design to acceptable levels to
provide reasonable protection against harmful interference. This unit can conduct and
radiateradiofrequencyenergyand,ifnotinstalledandusedinaccordancewiththein-
struction manual, may cause harmful interference to radio communications. The effects of
EMIwillalsodependuponanumberoffactorsexternaltotheunitlikeproximityofthe

-
Ensurethattheunitisfirmlygroundedtothegroundsystemofthebuildingor
the vehicle.
-
Locate the unit as far away from the eMI receptors like radio, audio and video
devices as possible.
-
Keep the DC side wires between the battery and the unit as short as possible.
-
Do not keep the battery wires far apart. Keep them taped together to reduce their
inductance and induced voltages. This reduces ripple in the battery wires and improves
performanceandefficiency.
