GENERAL Section 1 1.1 Safety Instructions Save This Manual Read this manual before installation, it contains important safety, installation, and operating instructions. Keep it in a safe place. All wiring must follow the National Electric Code, Provincial or other codes in effect at the time of installation, regardless of suggestions in this manual. - Page 4 1.1.2 Inverter Precautions • Inverters produce hazardous voltages. To avoid risk of harm or fire, the unit must be properly installed. • There are no user serviceable parts inside, do not remove the cover. • The inverter should not be mounted in a location that may be exposed to rain or water spray.

Page 5: Introduction
1.2 Introduction When operating, the direct current (DC) that enters the inverter from the batteries is filtered by a large input capacitor and switched “On” and “Off” by the Metal Oxide Silicon Field Effect Transistors (MOSFET) at a rate of 60 cycles per second, and directed into the transformer which steps the voltage up to 120 volts. -

Page 9: Support Items
2.2 Support Items 2.2.1 General Overview An inverter support system consists of all the equipment needed to supply DC power to the inverter. On a land vehicle the support system can be divided into two main categories depending on the size of the loads and their running time, these are: Light duty applications and heavy-duty applications. - Page 10 2.2.2 Deep Cycle Battery Theory There are two categories of lead acid deep cycle batteries; wet and sealed. Sealed batteries can be either gel cell or AGM (Absorbent Glass Mat) type. Deep cycle batteries are designed specifically for repetitive charge and discharge cycles. These batteries are also made to be discharged to a very low level before recharging.

- Page 23 Chart E: Battery Configuration: Batteries interconnect in two ways: Series or parallel. a) Series configuration: Increases voltage while keeping the Ampere Hour (AH) capacity constant. For example: Two deep cycle 12 Volt batteries @ 105 AH each connected in series, results in a total output of 24 Volts (12 Volts + 12 Volts) @ 105 AH b) Parallel configuration: Increases capacity while keeping the voltage constant.
- Page 24 Chart H: Waveform Discussion Pure sine waveform electrical power is the world's standard waveform for the electrical utility grid (see figure a below). This waveform is the naturally occurring waveform that is emitted from a rotating electrical generator, so it was a logical decision to make this the standard.

GLOSSARY Section 7 AGM: (Absorbent Glass Mat) A lead-acid battery that incorporates a sponge glass mat separator to immobilize the electrolyte. Because of the immobilized electrolyte, AGM batteries will not leak or spill. Alternating Current: Pulsating electric energy in which the direction of the electron flow is rapidly changed, so the end terminal becomes in rapid succession electrically positive, then negative. - Page 26 Open Circuit Voltage: The voltage at a battery terminal when no appreciable current is flowing. Polarity: The quality of an object characterized by two opposite charges, as in the positive and negative poles of a battery. Pure sine wave: World’s standard waveform for the electrical utility grid. This waveform is the naturally occurring waveform that is emitted from a rotating electrical generator.
