1. INTRODUCTION

3. How an Inverter/Charger Works

An 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 recharge your batteries.

There are two modes of operation associated with an inverter/charger:

Inverter Mode:

Direct current (DC) from the vehicles batteries is transformed into alternating current (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 incoming

AC is also converted to DC to recharge the vehicles batteries.

1. INTRODUCTION

4. Advantages of a Pure Sine Wave Inverter

Todays inverters come in two basic output waveforms: modified sine (which is actually a modified square wave) and pure sine wave. Modified sine wave inverters approximate a pure sine waveform and will run most appliances and electronics without any problems. These inverters are less expensive and, therefore, offer a viable alternative to more expensive pure sine inverters.

The output of a pure sine wave inverter is equal to or, in many cases, better than the grid power used in your home. Virtually any electronic device will operate from a pure sine wave inverter. Motors run cooler, microwaves usually cook faster and clocks keep better time just to name a few examples. Without compromising quality or performance, the MagnaSine provides you with all of the advantages of a pure sine wave inverter at a much lower cost than many on the market.

The MagnaSine is built on the same platform as our popular ME Series modified sine wave inverters allowing for an easy upgrade from the original ME installation.

This standard platform also helps reduce cost by using standard parts across many models. 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 Time

The MS Series inverter/charger can power a wide range of household appliances including small motors, hair dryers, clocks and other electrical devices. As with any appliance 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 the size and the type of appliance, the type of batteries installed in your mobile application, as well as the batterys capacity and age. Other factors such as the batterys state of charge and temperature can also affect the length of time your appliances can run.

Appliances such as TVs, VCRs, stereos, computers, coffee pots, incandescent lights and toasters can all be successfully powered by your inverter. Larger electrical appliances, however, such as stoves, water heaters, etc., can quickly drain your batteries and are not recommended for this application.

All electrical appliances are rated by the amount of power they consume. The rating is printed on the products nameplate label, usually located on its chassis near the AC power cord. Even though it is difficult to calculate exactly how long an inverter will run a particular appliance, the best advice is trial and error. Your MS

Series inverter has a built-in safeguard that automatically protects your batteries from over discharge.

NOTE: For optimum performance, a minimum battery bank of 200 AHr is recommended.

1. INTRODUCTION

7. MS Series Neutral-to-Ground Safety System

All MS Series inverters employ an internal, neutral-to-ground safety feature, in accordance with applicable electrical codes for use in mobile applications. This design prevents an electrical shock hazard between the vehicles neutral and the shore powers 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 relay when the inverter is operating from the batteries, thus creating a neutral to ground bond within the inverter.

External Neutral-to-Ground Switching (AC Shore Power Mode)

The inverters internal relay opens and removes the ground from the neutral conductor when the vehicle is connected to an external AC power source. The neutral is connected directly to the output neutral thus providing the neutral bond at the external AC source.

WARNING: Do not attempt to disable the the neutral-to-ground safety feature.

2. INSTALLATION

1. Unpacking and Inspection

Carefully remove the MS Series inverter from its shipping container and inspect all contents. If items appear to be missing or damaged, contact Magnum Energy at (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 for factory service.

ATTENTION: Electrostatic Sensitive Devices. Observe precautions for handling.

2. Pre-Installation

Before installing the inverter, read all of the instructions and cautionary markings contained in this manual.

NOTE: The inverter is heavy. Use proper lifting techniques during installation to prevent personal injury.

Locating the Inverter

The inverter must be mounted in a clean, dry, ventilated environment where the ambient temperatures will not exceed 122 ºF (50 ºC). The location must be fully accessible and protected from exposure to heat producing devices. You can mount the inverter horizontally, vertically or upside-down. It must be securely fastened to a shelf, bulkhead, or other structural part.

Allow enough clearance to access the AC and DC connection points as well as the inverters controls and status indicator. As with any inverter, it should be located as close to the batteries as possible. Longer battery cable runs tend to loose efficiency and reduce the overall performance of an inverter.

If you are planning to install dedicated batteries, other than the vehicles, make sure they are in a dedicated compartment that has ventilation to the outside. Also it is important that you never mount the inverter directly above the batteries as they emit corrosive fumes which could damage the inverters electronics.

Locating Dedicated Batteries (optional)

Dedicated batteries must be mounted in a clean, dry, ventilated environment where they are protected from high and low temperatures. The batteries must be mounted upright (if using liquid batteries) and securely fastened to the vehicle. The location must be fully accessible and protected from exposure to heat producing devices.

To ensure optimum performance, a ventilated battery enclosure is recommended.

The batteries should be located as close as possible to the inverter. Longer battery cable 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 inverters electronics.

NOTE: For optimum performance, Magnum Energy recommends using AGM

(absorbed glass mat) batteries such as Lifeline TM brand batteries.

CAUTION: Never locate dedicated batteries near the vehicles fuel tanks containing gasoline or propane.

Wiring

Pre-plan the wire and conduit runs. For maximum safety, run both AC and DC wires/cabling in (separate) conduit. Direct current wiring, due to its potential to generate RFI, should be tied together with electrical tape. Wiring and installation methods must conform to all applicable electrical codes.

NOTE: Run DC cabling in twisted pairs, keeping the runs as short as practical.

AC Connections

Use #10 AWG (or larger) THHN wire for all AC wiring. The inverters AC terminal blocks accept up to #6 AWG wire.

DC Connections

Battery to inverter cabling should be only as long as required. If using #2/0 AWG cables, 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 to connect the battery cables to the inverters DC terminals.

AC Grounding

The MS Series inverter/charger contains an internal neutral-to-ground switching circuit for the AC electrical system.

WARNING: The AC shore power neutral must be grounded ONLY through the shore power cable. Do not ground AC neutral to the vehicles chassis.

DC Grounding

The inverter/charger should always be connected to a permanent, grounded wiring system. For the majority of installations, the negative battery conductor is bonded to the vehicles safety-grounding conductor (green wire) at only one point in the system. The size for the conductor is usually based on the size of the largest conductor in the DC system. DO NOT connect the battery negative (-) cable to the vehicles safety ground. Connect it only to the inverters negative battery terminal.

If there are any non-factory installed DC appliances on board the vehicle, DO NOT ground them at the safety ground. Ground them only at the negative bus of the DC load center (as applicable).

Torque Requirements

Torque all AC wiring connections to 16 inch pounds. Torque DC cable connections to 10-12 foot pounds.

AC Main Panel

If the installation will be powering a wide-range of appliances throughout the vehicle, an AC main panel is often recommended. This is similar in appearance and function as your homes circuit breaker panel, providing an additional level of control and protection for the various circuits. Always refer to electrical codes for safe wiring practices.

Circuit Protection

If using a AC main panel for distribution, always use breakers that provide the correct ampere branch circuit protection in accordance with the National Electric

Code. The breakers must be properly rated for the appliances being powered.

NOTE: Both AC and DC disconnects / overcurrent protection must be provided as part of the installation.

Wire Routing

Determine all wire routes throughout the vehicle both to and from the inverter.

Conductors that are at risk to physical damage must be protected by conduit, tape, or placed in a raceway. Conductors passing through walls, bulkheads or other structural members must be protected to minimize insulation damage such as chafing.

During the installation, always avoid placing conductors near sources of chafing caused by vibration or constant rubbing.

CAUTION: Always check for existing electrical, plumbing or other areas of potential damage prior to making cuts in structural surfaces, bulkheads or walls.

Typical routing scenarios are:

AC Input wiring from the shore power source to the inverter

AC Input wiring from a generator (optional) to the inverter

DC Input wiring from the batteries to the inverter

AC Output wiring from the inverter to the coachs AC main panel or to dedicated circuits

Battery Temperature Sensor cable from the inverter to the batteries

2. INSTALLATION

3. Installation

NOTE: Read all instructions and cautionary markings located at the beginning of this manual and in the pre-installation section, before installing the inverter and batteries.

CAUTION: Do not mount the inverter or the batteries near the vehicles gasoline or propane fuel tanks.

Provide adequate clearance and ventilation to the inverter

Mount the inverter only on a noncombustible surfaces.

Maximum abient temperature MUST NOT exceed 113 °F (45 °C).

For Canadian installations, the inverters vents must face downward.

Inverter Mounting

Position the inverter in the designated mounting location: shelf, bulkhead or upside-down. Allow enough clearance to access the AC and DC connection points as well as the inverters controls and status indicator. Also allow for air flow in to and around the inverter, especially near the cooling fans (approximately 3).

Mark the mounting holes in the base of the inverters chassis. Remove the inverter and drill pilot holes into the mounting surface.

Secure the inverter to the mounting surface using appropriate screws and lock washers.

Remove the inverters AC access panel in accommodate the AC Input and Output wiring and conduit.

Ventilation Requirements

In order to provide optimum performance, longer inverter life and reliability, and avoid "Overtemp" fault conditions," clearances around the inverter MUST be:

Side and Back: 3 minimum - Front (with DC connections): 6" minimum

If the inverter is mounted in an enclosed compartment, airflow must be at least 100 cfm in order to maintain no more than a 20 0 C degree rise in compartment temperature. Minimum clearances can be reduced if airflow is increased, but in no case should clearance around inverter be less than 2" on all sides.

If an "Overtemp" faults occur, reduce the load or increase ventilation to the inverter.

2. INSTALLATION


Battery Cables and Sizing

Select the correct battery cables for the installation from the table. It is important to use the correct cable to achieve maximum efficiency from the system and reduce fire hazards associated with overheated cables. Undersized cables can also lower the inverters peak output voltage as well as reduce its surge power capability.

Long cable runs also reduce efficiency due to resistance in the cable. Always keep your cable runs a short as practical.

Battery cables must be color coded with colored tape or heat shrink tubing: RED for positive (+); BLACK for negative (-); and GREEN for DC ground.

The cables must have soldered and crimped lugs, crimped copper compression lugs, or aluminum mechanical lugs. Soldered connections alone are not acceptable for this application.

DC Wiring

Refer to the safety information at the beginning of the manual before proceeding. DC wires and cables should be tied together with wire ties or electrical tape approximately every 6 inches.

WARNING: De-energize all sources of power including batteries (DC), shore power (AC), and AC generator (if applicable).

CAUTION: Inverter is NOT polarity protected. Verify proper polarity BEFORE connecting the battery cables.

NOTE: DO NOT connect the battery cables to the inverter until all wiring is complete and the correct DC voltage and polarity has been verified.

NOTE: Make sure cables have a smooth bend radius and do not become kinked.

Place long cable runs in conduit and follow existing wire runs where possible.

DC Grounding

Route a grounding cable (GREEN) from the inverters ground lug to a dedicated vehicle ground.

Negative Cable

Route a negative cable (BLACK) from the house battery bank (or dedicated battery compartment) to the inverters negative terminal

Positive Cable

Route a positive cable (RED) from the house battery bank (or dedicated battery compartment) to the Fuse Block assembly (DC Disconnect). The DC disconnect is usually located next to or near the batteries. DO NOT connect the positive cable to the batteries at this time.

Route a positive cable (RED) from the Fuse Block assembly (DC Disconnect) to the

inverters positive terminal DO NOT connect the positive cable to the inverter at this time.


2. INSTALLATION


Battery Wiring

WARNING: During the installation and wiring process, cover exposed battery cable ends with electrical tape to prevent shorting the cables.

NOTE: DO NOT connect the positive cable to the inverter at this time.

Depending upon the type of battery you use in the installation (6 or 12 VDC), the batteries must be wired in series, parallel or series/parallel to provide 12 VDC. The interconnecting battery cables must be sized and rated exactly the same as those that used to connect the inverter.

When connecting the cable to the battery terminal, hardware should be installed in the following order: bolt, ring washer, cable lug, (battery terminal), ring washer, lock washer, nut. Tighten terminal connections to at least 10 to 12 foot pounds.

When two cables are connected to a terminal (i.e., negative terminal), the hardware should be installed in the following order: bolt, ring washer, DC negative cable lug, inverter negative cable lug, (battery terminal), ring washer, lock washer, nut.

Parallel Connection

(multiple 12 VDC batteries to create a 12 VDC string)

A parallel connection combines overall battery capacity by the number of batteries in the string. Even though there are multiple batteries, the voltage remains the same. In the example on the next page (Figure 7), four, 12 VDC, 100 AHr batteries are combined into a single string, resulting in a 12 VDC, 400 AHr bank.

Connect the negative battery terminals together using short cables.

Connect the positive battery terminals together using short cables.

Connect the negative battery cable (BLACK) from the inverter to the negative terminal of the end battery. At the same time, connect a DC ground cable between the negative terminal and the vehicles DC grounding bus.

Connect the positive (RED) battery cable from the inverter to the positive terminal of the battery at the opposite end of the string. This is essential to ensure even charging and discharging across the entire battery string.

NOTE: A fuse must be placed between the positive terminal and the positive (RED) battery cable to the inverter.

Once the batteries are completely wired and tested, coat the terminals with an approved anti-oxidizing spray.

A fuse or circuit breaker must be located within 18 inches of the battery to protect the DC wiring system. The device must be rated to match the size of the cable, but can be rounded up to the next larger size (i.e., a cable rated at 150 amps can accept a 175 amp fuse) as necessary.

Mount the fuse block (or circuit breaker assembly) as near as practical to the batteries.

Remove the fuse (or open the circuit breaker) and connect a short cable (same rating as the battery cables) to one end of the fuse block.

Connect the short cable to the positive battery terminal.

Connect the positive cable (RED) from the inverter to the assembly. DO NOT connect the positive cable to the inverter at this time.

Securely tighten the fuse blocks lugs. Once the entire installation is complete, reinsert the fuse into the fuse block before connecting the positive cable to the inverter.

3. OPERATION

1. Operating the Inverter

The MS Series inverter/charger has two modes of operation: INVERTER (providing power to your appliances from the batteries) and AC (running from shore power or a generator). Whenever the inverter is in AC mode, it passes power directly to your appliances as well as recharges the batteries using a 3-stage battery charger (Bulk,

Absorption and Float). This approach to battery charging provides rapid and complete charging cycles without placing undue stress on the batteries. Inverter operation is fully automatic.

Search

With search mode enabled, the inverter pulses the AC output looking for an electrical appliance (typically 5 to 100 watts, depending upon the setting youve selected). Whenever there is no load detected, the inverter automatically goes into search mode (sleep) to minimize energy consumption. During this time, the inverters green LED flashes (fast) to indicate SEARCH mode. When an appliance is switched on inside the coach, the inverter recognizes the need for power and automatically starts the inverter

Inverter Mode

Whenever AC Shore Power is no longer sensed, the inverter automatically transfers to battery power with no interruption to your appliances. The inverters green LED flashes once every 2 seconds (medium flash) to indicate it is running on battery power and providing AC to the coach.

AC Shore Power Mode

Whenever AC Shore Power is sensed, the inverter automatically transfers to the shore power with minimal interruption to your appliances.

Bulk Charge Mode

Whenever the inverter is running on nominal AC Shore Power, it charges the batteries. The inverters green LED stays ON (solid) to indicate the first stage of charging. During bulk charging, the charger supplies the maximum amount of constant current to the batteries. As the battery voltage rises to a set value (typically

14.1 VDC for GEL, 14.3 VDC for AGM, and 14.6 VDC for liquid lead acid), the charger will then switch to the next charging mode.

Absorption Charge Mode

As the inverter continues to run on nominal AC Shore Power, and the batteries have been successfully bulk charged, the charger enters its second stage of charging.

The inverters green LED flashes once every second (fast flash) to indicate absorption charging for 1 - 3 hours depending upon battery bank selection (refer to the MS

Series Remote manual). The charger then switches to its final charging mode.

Float Charge Mode

As AC shore power continues, the inverters green LED flashes once every 8 seconds (slow flash) to indicate the third and final stage of charging. The batteries are held at the float voltage (typically 13.6 VDC for GEL, 13.1 VDC for AGM, and 13.4

VDC for liquid lead acid) as long as AC is present at the inverters input. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries) and ensures the batteries are maintained at optimum capacity.

Battery Saver TM Mode

Designed to keep batteries fully charged over long periods (storage) without drying them out. Whenever the charger is in float for 4 hours with no DC loads running, the charger will turn OFF. If the battery voltage drops below 12.5 VDC, the charger will automatically initiate float mode to return them to a full charge.

3. OPERATION

1. Operating the Inverter, continued

Fault or Alarm Conditions

The inverter monitors the AC Shore Power, the batteries and itself. Whenever a condition occurs that is outside the normal operating parameters, the inverter will take the necessary steps to protect your appliances, batteries or itself from damage.

Low Battery

Whenever the battery voltage reaches a low level, the inverter will initiate Low

Battery Cutoff (LBCO) which automatically shuts the inverter down, along with all connected loads, to protect the batteries from over-discharge damage. The inverters LED turns OFF to indicate the fault condition.

High Battery

As the inverter is charging, it constantly monitors the batteries. In the event the battery voltage approaches too high of level, it automatically turns off the battery charger to protect the batteries from damage. The inverters LED turns OFF to indicate the fault condition.

NOTE: High battery voltage may be caused by excessive voltage from the alternator, solar panels or other external charging sources.

Overload

During inverter and AC Shore Power operation, the inverter monitors the AC and

DC circuits. In the event of a short-circuit or overload condition, the inverter will shut down. The inverters LED turns OFF to indicate the fault condition.

Overtemperature

During inverter operation, if the inverter becomes overheated, it will shut down to protect itself from damage. The inverters LED turns OFF to indicate the fault condition.
