3. CAUTION! For SAM-2000-12 and SAM-3000-12, the full rated power cannot be drawn from 1 NEMA5-15R

outlet as each outlet is rated for only 15A (1725VA) and is protected by 15A breaker. If a single load rated

at > 1725VA is required to be powered, output from 2 NEMA5-15 outlets should be paralleled and then

fed to this load. If a load > 1725VA / 15A is powered from a single breaker protected NEMA5-15R outlet,

its 15A breaker will trip (pops out) and will have to be reset manually (pushed in).

Caution!

1. DO NOT connect 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 from this inverter should NOT be connected in parallel with another

AC source like grid / generator / another inverter - SEVERE DAMAGE WILL OCCUR!

3. If the AC output from this inverter is required to be fed to an AC Distribution Panel /

SubPanelforbackupACpower,asuitableTransferSwitchlikeSamlexAmerica

Transfer Switch Model No. STS-30 should be used. The Transfer Switch will prevent

parallel operation of AC output of this inverter with the other AC source.

facturer. This may not be possible in all cases and hence, can be guessed at best, based on

some general Rules of Thumb.

Table 4.4 lists some common loads that require high surge power on start up. A “Siz-

ing Factor” has been recommended against each which is a Multiplication Factor to be

applied to the rated running Watt rating of the load to arrive at the Continuous Power

Rating of the inverter (Multiply the running Watts of the device/ appliance by the Sizing

Factor to arrive at the size of the inverter).
