limiting electro-Magnetic
Interference (eMI)
These inverters contain internal switching devices that generate conducted and radiated
electromagneticinterference(EMI).TheEMIisunintentionalandcannotbeentirely
eliminated.ThemagnitudeofEMIis,however,limitedbycircuitdesigntoacceptable
levelsasperlimitslaiddowninNorthAmericanfCCStandardfCCPart15(B),ClassB.
These limits are designed to provide reasonable protection against harmful interfer-
ence when the equipment is operated in a residential environment. These inverters can
conductandradiateradiofrequencyenergyand,ifnotinstalledandusedinaccordance
withtheinstructionmanual,maycauseharmfulinterferencetoradiocommunications.

inFo
- ensure that the inverter is firmly grounded to the ground system
of the building or the vehicle
- LocatetheinverterasfarawayfromtheEMIreceptorslikeradio,
audio and video devices as possible
- KeeptheDCsidewiresbetweenthebatteryandtheinverter
as short as possible.
- DoNoTkeepthebatterywiresfarapart.Keepthemtapedtogetherto
reduce their inductance and induced voltages. This reduces ripple in the bat-
tery wires and improves performance and efficiency.
- ShieldtheDCsidewireswithmetalsheathing/copperfoil/braiding:
