SECTION 2 | General Information 2.1. DEFINITIONS The following definitions are used in this manual for explaining various electrical concepts, specifications and operations: Peak Value: It is the maximum value of electrical parameter like voltage / current. RMS (Root Mean Square) Value: It is a statistical average value of a quantity that varies in value with respect to time. - Page 10 SECTION 2 | General Information tance X to cause the current to lag the voltage by 90° and that of the capacitive reac- tance X to cause the current to lead the voltage by 90° are exactly opposite and the net effect is a tendency to cancel each other.

For example, in motor driven loads like Air-conditioning and Refrigeration Compressors and in Well Pumps (using Pressure Tank), the Starting Surge Current / LRA may be as high as 10 times its rated Full Load Amps (FLA) / Maximum Continuous Running Power Rating.
- Page 12 SECTION 2 | General Information Resistive Load: A device or appliance that consists of pure resistance (like filament lamps, cook tops, toaster, coffee maker etc.) and draws only Active Power (Watts) from the inverter. The inverter can be sized based on the Active Power rating (Watts) of resistive type of loads without creating overload (except for resistive type of loads with Tungsten based heating element like in Incandescent Light Bulbs, Quartz Halogen Lights and Quartz Halogen Infrared Heaters.
- Page 13 SECTION 2 | General Information voltage crossing (for timing control) will not work properly from a voltage that has a Modified Sine Waveform. Also, as the Modified Sine Wave is a form of Square Wave, it is comprised of multiple Sine Waves of odd harmonics (multiples) of the fundamental frequency of the Modified Sine Wave.

Page 16: Limiting Electromagnetic Interference (Emi)
SECTION 3 | Limiting Electro-Magnetic Interference (EMI) 3.1 EMI AND FCC COMPLIANCE These inverters contain internal switching devices that generate conducted and radiated electromagnetic interference (EMI). The EMI is unintentional and cannot be entirely eliminated. The magnitude of EMI is, however, limited by circuit design to acceptable levels as per limits laid down in North American FCC Standard FCC Part 15(B), Class B. -
