1. INTRODUCTION3. How an Inverter/Charger WorksAn inverter takes direct current (DC) from your batteries and turns it into alternating current (AC), exactly like you use at home. It also takes alternating current(when connected to shore power) and transforms it into direct current to rechargeyour batteries.There are two modes of operation associated with an inverter/charger:Inverter Mode:Direct current (DC) from the vehicle s batteries is transformed into alternatingcurrent (AC) for use with you household electrical appliances.Charger Mode:Alternating current (AC) is taken directly from shore power (or other AC sources)and passed directly to your household appliances. At the same time, the incomingAC is also converted to DC to recharge the vehicle s batteries.Figure 1MS Series Inverter / Charger2 2004 - Magnum Energy, Inc.
1. INTRODUCTION4. Advantages of a Pure Sine Wave InverterToday s inverters come in two basic output waveforms: modified sine (which isactually a modified square wave) and pure sine wave. Modified sine wave invertersapproximate a pure sine waveform and will run most appliances and electronics without any problems. These inverters are less expensive and, therefore, offer a viablealternative to more expensive pure sine inverters.The output of a pure sine wave inverter is equal to or, in many cases, better thanthe grid power used in your home. Virtually any electronic device will operate from apure sine wave inverter. Motors run cooler, microwaves usually cook faster and clockskeep better time just to name a few examples. Without compromising quality orperformance, the MagnaSine provides you with all of the advantages of a pure sinewave inverter at a much lower cost than many on the market.The MagnaSine is built on the same platform as our popular ME Series modifiedsine wave inverters allowing for an easy upgrade from the original ME installation.This standard platform also helps reduce cost by using standard parts across manymodels. All Magnum accessories such as the Remote Controller, AGS (AutoGen Start),and network accessories are standard for all ME, RD and MS Series inverters.5. Appliances and Run TimeThe MS Series inverter/charger can power a wide range of household appliancesincluding small motors, hair dryers, clocks and other electrical devices. As with anyappliance using batteries for power, there is a certain length of time that it can run this is called run time. Actual run time depends on several variables including thesize and the type of appliance, the type of batteries installed in your mobile application, as well as the battery s capacity and age. Other factors such as the battery sstate of charge and temperature can also affect the length of time your appliancescan run.Appliances such as TVs, VCRs, stereos, computers, coffee pots, incandescentlights and toasters can all be successfully powered by your inverter. Larger electricalappliances, however, such as stoves, water heaters, etc., can quickly drain yourbatteries and are not recommended for this application.All electrical appliances are rated by the amount of power they consume. Therating is printed on the product s nameplate label, usually located on its chassis nearthe AC power cord. Even though it is difficult to calculate exactly how long aninverter will run a particular appliance, the best advice is trial and error. Your MSSeries inverter has a built-in safeguard that automatically protects your batteriesfrom over discharge.NOTE: For optimum performance, a minimum battery bank of 200 AHr isrecommended.DeviceBlenderComputerDrillHot PlateLight (Flo)MicrowaveLoad400 W300 W500 W1800 W10 W1000 WDeviceCoffee MakerColor TVHair DryerIronLight (Inc)RefridgeratorLoad1200 W150 W1000 W1000 W100 W500 WTable 1 - Typical Appliance Power Consumption 2004 - Magnum Energy, Inc.3

1. INTRODUCTION7. MS Series Neutral-to-Ground Safety SystemAll MS Series inverters employ an internal, neutral-to-ground safety feature, inaccordance with applicable electrical codes for use in mobile applications. Thisdesign prevents an electrical shock hazard between the vehicle s neutral and theshore power s neutral (when connecting the inverter to shore power).Internal Neutral-to-Ground Switching (Battery Inverter Mode)The AC output neutral is connected to the chassis ground by an internal relaywhen the inverter is operating from the batteries, thus creating a neutral to groundbond within the inverter.External Neutral-to-Ground Switching (AC Shore Power Mode)The inverter s internal relay opens and removes the ground from the neutralconductor when the vehicle is connected to an external AC power source. Theneutral is connected directly to the output neutral thus providing the neutral bond atthe external AC source.WARNING: Do not attempt to disable the the neutral-to-ground safety feature.Figure 4MS Series Inverter / Neutral-to-Ground Safety System6 2004 - Magnum Energy, Inc.
2. INSTALLATION1. Unpacking and InspectionCarefully remove the MS Series inverter from its shipping container and inspect allcontents. If items appear to be missing or damaged, contact Magnum Energyat (425) 353-8833 or your authorized Magnum Energy dealer. If at all possible,retain the shipping container in the event the unit ever needs to be returned forfactory service.ATTENTION: Electrostatic Sensitive Devices. Observe precautions forhandling.2. Pre-InstallationBefore installing the inverter, read all of the instructions and cautionary markingscontained in this manual.NOTE: The inverter is heavy. Use proper lifting techniques during installation toprevent personal injury.Locating the InverterThe inverter must be mounted in a clean, dry, ventilated environment where theambient temperatures will not exceed 122 ºF (50 ºC). The location must be fullyaccessible and protected from exposure to heat producing devices. You can mountthe inverter horizontally, vertically or upside-down. It must be securely fastened to ashelf, bulkhead, or other structural part.Allow enough clearance to access the AC and DC connection points as well as theinverter s controls and status indicator. As with any inverter, it should be located asclose to the batteries as possible. Longer battery cable runs tend to loose efficiencyand reduce the overall performance of an inverter.If you are planning to install dedicated batteries, other than the vehicle s, makesure they are in a dedicated compartment that has ventilation to the outside. Also itis important that you never mount the inverter directly above the batteries as theyemit corrosive fumes which could damage the inverter s electronics.Locating Dedicated Batteries (optional)Dedicated batteries must be mounted in a clean, dry, ventilated environmentwhere they are protected from high and low temperatures. The batteries must bemounted upright (if using liquid batteries) and securely fastened to the vehicle. Thelocation must be fully accessible and protected from exposure to heat producingdevices.To ensure optimum performance, a ventilated battery enclosure is recommended.The batteries should be located as close as possible to the inverter. Longer batterycable runs tend to loose efficiency and reduce the overall performance of an inverter.Also, do not mount the batteries beneath the inverter (or in the same compartment).Batteries emit corrosive fumes which could damage the inverter s electronics.NOTE: For optimum performance, Magnum Energy recommends using AGM(absorbed glass mat) batteries such as LifelineTM brand batteries.CAUTION: Never locate dedicated batteries near the vehicle s fuel tankscontaining gasoline or propane. 2004 - Magnum Energy, Inc.7

Pre-Installation, continuedHardware / Materials RequiredConduit, strain-reliefs and appropriate fittings1/4" mounting bolts and lock washersElectrical tapeWire tiesTools RequiredMisc screw driversDrill and drill bitsLevelLevelPliersPencil or Marker1/2" wrenchWire strippersMultimeterWiringPre-plan the wire and conduit runs. For maximum safety, run both AC and DCwires/cabling in (separate) conduit. Direct current wiring, due to its potential togenerate RFI, should be tied together with electrical tape. Wiring and installationmethods must conform to all applicable electrical codes.NOTE: Run DC cabling in twisted pairs, keeping the runs as short as practical.AC ConnectionsUse #10 AWG (or larger) THHN wire for all AC wiring. The inverter s AC terminalblocks accept up to #6 AWG wire.DC ConnectionsBattery to inverter cabling should be only as long as required. If using #2/0 AWGcables, do not exceed 5 feet (one way) for 12 VDC systems.Crimped and sealed copper ring terminal lugs with a 5/16 hole should be used toconnect the battery cables to the inverter s DC terminals.AC GroundingThe MS Series inverter/charger contains an internal neutral-to-ground switchingcircuit for the AC electrical system.WARNING: The AC shore power neutral must be grounded ONLY throughthe shore power cable. Do not ground AC neutral to the vehicle schassis.DC GroundingThe inverter/charger should always be connected to a permanent, groundedwiring system. For the majority of installations, the negative battery conductor isbonded to the vehicle s safety-grounding conductor (green wire) at only one point inthe system. The size for the conductor is usually based on the size of the largestconductor in the DC system. DO NOT connect the battery negative (-) cable to thevehicle s safety ground. Connect it only to the inverter s negative battery terminal.If there are any non-factory installed DC appliances on board the vehicle, DO NOTground them at the safety ground. Ground them only at the negative bus of the DCload center (as applicable).8 2004 - Magnum Energy, Inc.

encodes a sine wave. The duty cycle of the output is changed such that the power transmitted is exactly that of a sine-wave. This output can be used as-is or, alternatively, can be filtered easily into a pure sine wave. This report documents the design of a true sine wave inverter, focusing on the inversion of a DC high-voltage source.
Again modified sine wave inverters are named after their output waveform. The output of the modified sine wave inverter cycles through positive, ground and negative voltage as shown in the diagram above, to give a similar output waveform to pure sine wave. Modified sine wave inverters are a much cheaper alternative to pure sine wave inverters .
