• Use insulated tools to reduce the chance of electrical shock or accidental short circuits.

• There are no user-serviceable parts contained in this product.

• This unit is provided with integral protection against overloads.

• Live power may be present at more than one point since an inverter utilizes both DC (batteries, PV, etc.,) and AC (utility or generator) power. To reduce risk of electric shock, ensure all DC and AC wiring is disconnected prior to installing or performing maintenance on the inverter. Turning off the inverter will not reduce this risk, the inverter must be totally disconnected from all sources.

• Use Class 1 wiring methods for ﬁeld wiring connections to terminals of a Class 2 circuit.

• Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.

• Always verify proper wiring prior to starting the inverter.

• Use only copper wires with a minimum temperature rating of 90°C (194°F).

• AC wiring must be no less than 10 AWG (5.3 mm²) gauge copper wire.

• Battery cables should be no less than #4/0 AWG (107.2 mm²) for 12-volt systems. Crimped and sealed copper ring terminal lugs with a 5/16 hole should be used to connect to the DC terminals on the inverter.

• Torque all AC wiring connections and DC cable connections to the required torque values.

• The inverter must be properly installed, see Section 2.2 “Mounting the Inverter” in this manual.

• Overcurrent protection for the battery supply is not provided as an integral part of this inverter. Overcurrent protection of the battery cables must be provided as part of the system installation. Refer to Section 2.4 “DC Wiring” for more information.

Page ii

Safety Information

• Overcurrent protection for the AC output wiring is not provided as an integral part of this inverter. Overcurrent protection of the AC output wiring must be provided as part of the system installation. Refer to Section 2.5 “AC Wiring” for more information.

• The AC output neutral conductor and the DC negative conductors are not connected (bonded) to the inverter chassis. Both the input and output conductors are isolated from the enclosure and each other. System grounding, if required, is the responsibility of the system installer and must comply with local and national electrical codes and standards. Refer to the Section 2.6 “Grounding Inverters” for more information.

Battery Safety

• Use insulated tools and be very careful when working around batteries, they can produce extremely high currents if short-circuited (e.g., dropping a metal tool across the battery terminal), which could cause a ﬁre or explosion.

• Read and follow the battery manufacturer’s safety precautions before installing the inverter and batteries. Always verify proper polarity and voltage before connecting the batteries to the inverter. Once the batteries are connected to the inverter, ensure the maintenance and charging requirements (i.e., charge voltage and charge rate) provided by the battery manufacturer are followed to extend the life of the batteries and to prevent damage to the batteries while charging.

• Wear eye protection such as safety glasses, and avoid touching your eyes and face when working with batteries to keep any ﬂ uid/corrosion on the battery from coming in contact with eyes and skin. Have plenty of fresh water and soap nearby and thoroughly wash in case battery acid contacts skin, clothing, or eyes. In the event of exposure to the eyes, ﬂood them for at least 15 minutes with running water and seek immediate medical attention. Baking soda neutralizes lead acid battery electrolyte and vinegar neutralizes spilled NiCad and NiFe battery electrolyte; depending on your battery type, keep a supply on hand near the batteries.

• Remove all jewelry such as rings, watches, bracelets, etc., when installing or performing maintenance on the batteries and inverter. A battery can produce a short-circuit current high enough to weld metal jewelry, causing severe burns.

• Never work alone. Always have someone within the range of your voice or close enough to come to your aid when working around batteries.

• Use proper lifting techniques when working with batteries.

• Never use old or untested batteries. Check each battery’s label for age, type, and date code to ensure all batteries are identical.

• Batteries are sensitive to changes in temperature. Install batteries in a stable environment.

• Batteries can produce explosive gasses, so install batteries in a well-ventilated area. For compartment or enclosure installations, always vent batteries from the highest point to the outside. Design the battery enclosure to prevent accumulation and concentration of hydrogen gas in “pockets” at the top of the compartment.

• Provide at least one inch of air space between batteries to provide optimum cooling.

• Never smoke or allow a spark near batteries.

• To prevent a spark at the battery and reduce the chance of explosion, always connect the cables to the batteries ﬁrst. Then connect the cables to the inverter.

• Never charge a frozen battery.

• The battery bank should be installed in a clean, dry, ventilated environment where they are protected from high and low temperatures. If installed in a vehicle/boat, the batteries must be mounted upright (if using liquid batteries) and securely fastened. The location must be fully accessible and protected from exposure to heat producing devices, and away from any fuel tanks.

Introduction

1.0 Introduction

Congratulations on your purchase of a ME-G Series inverter/charger from Sensata. The ME-G Series products include the ME2012-G, ME2512-G, and ME3112-G inverters; all are under the Magnum-Dimensions brand from Sensata Technologies. The ME-G Series is a modiﬁ ed sine wave inverter designed especially for mobile applications. Powerful, yet simple to operate, this inverter/ charger will provide you with the years of trouble-free performance.

Installation is easy. Simply connect the inverter’s output to your distribution circuits or electrical panel, connect your AC to the inverter, connect the batteries, and then switch it on for power.

Info: This is a sizable manual and much of it is fairly technical. Terms may be used throughout the manual that are unfamiliar to you. Refer to the Inverter/Charger Terminology glossary in Appendix D for clariﬁ cation.

The ME-G Series inverter/chargers provide the following:

• 2000, 2500, or 3100-watt models in a small footprint—less area needed for installation

• Modiﬁ ed sine wave output

• Automatic Power Factor Corrected (PFC) multi-stage battery charging

• RS485 standard communication protocol

• Factory-installed Ground Fault Circuit Interrupter (GFCI) outlet (with test and reset capability) for AC output

• Remote and Network ports (easy connection for optional accessories)

• Inverter-mounted ON/OFF switch with LED indicator

• 30 amps per leg AC pass-through capability

• Field-serviceable for qualiﬁ ed personnel—tested repair kits available

• Automatic battery temperature compensation (using battery temperature sensor)—for optimum charging even during extreme temperature changes

• Overcurrent, over-temperature, and high/low battery voltage protection

Regulatory Compliance

The ME-G Series inverter/charger is designated as a standalone power inverter with an internal battery charger. It can be connected to shorepower/utility grid (or to a generator) to allow the inverter batteries to be charged, and to power inverter loads while connected. The ME-G series is not a grid-interactive (also known as utility-interactive) inverter and does not have the capability to export (or sell) power back into the utility grid.

The ME-G Series has been tested and listed to UL 458, 5th Edition (Power Converters/Inverters and Power Converter/Inverter Systems for Land Vehicles and Marine Crafts) for use in the US; and is also certiﬁ ed to CSA C22.2 No. 107.1-01 (General Use Power Supplies) for use in Canada. It has been tested and certiﬁed to these product safety standards by Intertek Testing Services (known as ETL), which is a Nationally Recognized Testing Laboratory (NRTL). NRTL’s are qualiﬁed organizations that meet Occupational Safety and Health Administration (OSHA) regulations to perform independent safety testing and product certiﬁ cation.

1.1 How an ME-G Series Inverter/Charger Works

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

• Inverter Mode: When the inverter is properly connected to batteries and turned on, the direct current (DC) from the batteries is transformed into a modiﬁ ed sine wave alternating current (AC). This AC is similar to the voltage provided by a utility for your home, and is used to power the electrical appliances (i.e., AC loads) connected to the inverter’s output.

• Standby Mode: When an external source of AC power (e.g., utility or onboard generator) is connected and qualiﬁ ed on the inverter’s AC input, it operates in Standby mode. In Standby mode, the unit operates as a battery charger to convert the incoming AC power into DC power to recharge the batteries; and at the same time, automatically closes an internal AC transfer relay to pass the incoming AC power directly to the inverter’s output to continue powering the connected electrical appliances.

Introduction

1.2 What Appliances will run from a Modiﬁ ed Sine Wave Inverter

Today’s inverters come in two basic output waveforms: modiﬁ ed sine wave (a modiﬁ ed square wave—see Figure C-1 in Appendix C) and pure sine wave. Modiﬁ ed sine wave inverters approximate a pure sine waveform and will run most appliances and electronics without problems. These inverters are less expensive, and therefore, offer a viable alternative to more expensive pure sine inverters.

The output of the ME-G Series is a modiﬁ ed sine wave which will run most electronic and household items, including but not limited to: TV, VCR, satellite dish receiver, computers, and printers. Some devices such as rechargeable power supplies for phones, drills, and other like items may not run, and could even be at risk for damage from modiﬁ ed sine wave inverters.

1.3 Features and Beneﬁ ts

The ME-G Series inverter/charger allows easy access to wiring, circuit breakers, and controls. Their die cast baseplate with one-piece aluminum cover ensures maximum durability with minimum weight, as well as a cooler, more efﬁ cient operation.

The bottom of ME-G inverters are equipped with the following (refer to Figures 1-1 and 1-2):

Power ON/OFF Switch – a momentary pushbutton switch that alternately turns the

inverter on or off.

Status LED Indicator – this green LED illuminates to provide information on the inverter

or charger operation.

Stack/Accessories Connection Port (red label) – a RJ11 port that accepts optional

accessories. Note: Stacking feature not available with ME-G Series.

Network Connection Port (green label) – a RJ11 port that accepts optional network

capable accessories (e.g., Auto Gen Start or Battery Monitor).

Remote Connection Port (blue label) – a RJ11 port that allows an optional remote

control to be connected.

Battery Temperature Sensor Connection Port (yellow label) – RJ11 port that

accepts the remote Battery Temperature Sensor (BTS).

DC Equipment Ground Terminal – this connection is used to tie the exposed chassis

of the inverter to the DC grounding system. This terminal accepts CU/AL conductors from #14 to #2 AWG (2.1 to 33.6 mm2).

AC Entry/Exit Connections – two 3/4” knockouts provided with cable-clamp strain

reliefs to allow and hold the AC input and output ﬁ eld wiring.

Intake Air Vents – ventilation openings to pull in air to help keep the inverter cool for

peak performance.

Positive DC Terminal – provides a 360 degree connection point for the positive (+)

cable from the battery bank; consists of a 5/16-18 bolt with a Kep or Flange nut on to hold the battery cable to the DC terminal.

Negative DC Terminal – provides a 360 degree connection point for the negative (–)

cable from the battery bank; consists of a 5/16-18 bolt with a Kep or Flange nut on to hold the battery cable to the DC terminal.

Mounting Flange – used to secure the inverter to a shelf or wall.

Introduction

The left side of ME-G Series inverters are equipped with the following features (see Figure 1-3):

Exhaust Air Vents – ventilation openings that allow heated air to be removed by the

internal cooling fan.

Model/Serial Number Label – includes model/serial number information, date of

manufacture, and inverter and charger speciﬁ cations. See the ME-G Series speciﬁ cations in Appendix A for more information and a list of available models.

AC Access Cover – provides access to the internal AC wiring terminal block (see Figure

2-8). This terminal block is used to hard wire all inverter AC input and output wiring connections. Remove the two screws to access the AC wiring terminal block.

GFCI (Ground Fault Circuit Interrupter) – a 20-amp rated dual outlet that quickly

stops the ﬂow of electricity in the event a ground fault occurs on the device that is plugged into the inverter.

HOT 1 Input – this 30-amp circuit breaker protects the unit’s internal charger wiring and pass-thru relay while in Standby mode. The circuit breaker pops out when it opens—

press in to reset. The input circuit breaker is not branch-rated, therefore branch-rated circuit breakers must be installed in the inverter’s input wiring.

GFCI Output – this 20-amp circuit breaker is branch-rated and protects the wiring to the

GFCI outlet. This circuit breaker pops out when it opens—press in to reset. It can also be manually pulled to disconnect the inverter’s loads.

CAUTION: The inverter’s internal AC transfer relay is rated for 30 amps per wired input (not the GFCI circuit). The pass-thru current must be no greater than 30 amps per leg or damage to the relays may occur.

2.0 Installation

Info: Installations should be performed by qualiﬁ ed personnel, such as a licensed

or certiﬁ ed electrician. It is the installer’s responsibility to determine which safety codes apply and to ensure that all applicable installation requirements are followed. Applicable installation codes vary depending on the speciﬁ c location and application of the installation.

CAUTION: Review the “Important Product Safety Information” on pages ii-v before any installation.

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

The simpliﬁ ed system diagram shown in Figure 2-1 should be reviewed to assist you in planning and designing your installation. This drawing is not intended to override or restrict any national or local electrical codes. This drawing should not be the determining factor as to whether the installation is compliant, that is the responsibility of the electrician and the on-site inspector.

2.1 Pre-Installation

Before proceeding, read the entire Installation section to determine how to best install your ME-G inverter/charger. The more thorough you plan in the beginning, the better your inverter needs will be met.

2.1.1 Unpacking and Inspection

Carefully remove the ME-G Series inverter/charger from its shipping container and inspect all contents. Verify the following items are included:

• The ME-G Series inverter/charger

• Red and black DC terminal covers with Phillips screws

• Two 5/16” Kep or Flange nuts (installed on the DC terminals)

• Battery Temperature Sensor

• Warning label

• ME-G Series Owner’s Manual

If items appear to be missing or damaged, contact your Magnum product authorized dealer or Sensata. If at all possible, keep your shipping box to help protect your inverter from damage if it ever needs to be returned for service. Save your proof-of-purchase as a record of your ownership; it will also be needed if the unit should require in-warranty service.

Record the unit’s model and serial number in the front of this manual in case you need to provide this information in the future. It is much easier to record this information now, instead of trying to gather it after the unit has been installed.

2.1.3 Locating the Inverter

Only install the inverter in a location that meets the following requirements: Clean and Dry – The inverter should not be installed in an area that allows dust, fumes, insects,

or rodents to enter or block the inverter’s ventilation openings. This area also must be free from any risk of condensation, water, or any other liquid that can enter or fall on the inverter. The inverter uses stainless steel fasteners, plated copper busbars, and a power-coated aluminum base, and the internal circuit boards are conformal coated—all to help ﬁ ght the harmful effects of corrosive environments. However, the inverter’s life is uncertain if used in these types of environments, and inverter failure under these conditions is not covered under warranty.

Info: If the inverter is installed in an area where moisture may occur, we recommend putting silicone dielectric grease compound into the electrical ports (Figure 1-1, Items 3-6). Before installing the cables, or if leaving any ports open, squirt a liberal amount into each port. Silicone dielectric compound makes an effective moisture and corrosive

barrier to help protect and prevent corrosion to the RJ11 connections.

Cool – The inverter should be protected from direct sun exposure or equipment that produces extreme heat. The ambient temperature around the inverter must not exceed 77°F (25°C) to meet power speciﬁ cations.

Ventilation – In order for the inverter to provide full output power and avoid over-temperature fault conditions, do not cover or block the inverter’s ventilation openings or install this inverter in an area with limited airﬂ ow. The inverter uses two fans to provide forced air cooling, these fans pull in air through the intake vents (Figure 1-2, Item 9) and blow out air through the exhaust vents (Figure 1-3, Item 13). Allow at the minimum an airspace clearance of 6” (15.2 cm) at the intake and exhaust vents, and 3” (7.6 cm) everywhere else to provide adequate ventilation.

If installed in an enclosure, a fresh air intake opening must be provided directly to the front side (intake vents) of the inverter and an exhaust opening on the back side (exhaust vents) of the inverter. This allows cool air from the outside to ﬂ ow into the inverter, and allows interior heated air to exit the inverter and the enclosure. When mounted in an enclosed compartment, airﬂ ow must be ≥ 100 cfm in order to maintain no more than a 68°F (20°C) rise in compartment temperature.

CAUTION: Do not mount this inverter in a zero clearance compartment, nor cover or obstruct the ventilation openings—overheating may result.

Safe – Keep any ﬂ ammable/combustible material (e.g., paper, cloth, plastic, etc.) that may be ignited by heat, sparks, or ﬂ ames at a minimum distance of 2 feet (61 cm) away from the inverter.

WARNING: The ME-G Series inverter/charger is not ignition-protected. Do not install this inverter in any area that contains extremely ﬂ ammable liquids like gasoline or propane.

Close to the battery bank – The inverter should be located as close to the batteries as possible. Long DC wires tend to loose efﬁ ciency and reduce the overall performance of an inverter. However, the unit should NOT be installed in the same compartment as the batteries, or mounted where it will be exposed to gases produced by the batteries. These gases are corrosive and will damage the inverter; also, if these gases are not ventilated and allowed to collect, they could ignite and cause an explosion.

Accessible – Do not block access to the inverter’s remote control and accessory ports, as well as the inverter’s on/off switch and status indicator. Allow enough room to access the AC and DC wiring terminals and connections, as they will need to be checked and tightened periodically. See Figure 2-3 for the ME-G Series inverter/charger’s dimensions.

Away from sensitive electronic equipment – High powered inverters can generate levels of RFI (Radio Frequency Interference). Locate any electronic equipment susceptible to radio frequency and electromagnetic interference as far away from the inverter as possible.

Installation

2.2 Mounting the Inverter

The inverter base can reach a temperature up to 90°C (194°F) and should be mounted on a noncombustible surface*. This surface and the mounting hardware must also be capable of supporting at least twice the weight of the inverter. To meet regulatory requirements, the ME-G Series must be mounted in one of the following positions, as shown in Figure 2-2:

• above or under a horizontal surface (shelf or table),

• on a vertical surface (wall) with the DC terminals to the right,

• on a vertical surface (wall) with the DC terminals toward the bottom, the MP-HOOD (inverter hood) installed on the top, and either the ME-CB or MPX-CB (Conduit Box) installed on the inverter’s bottom.

Info: The ME-CB, MPX-CB, and MMP Series enclosures prevent material from falling out the bottom during an internal ﬁ re, and also allow sufﬁ cient ventilation to prevent the inverter from overheating under normal operating conditions. The MP-HOOD inverter hood helps prevent items from falling inside causing damage to the inverter.

After determining the mounting position, refer to the physical dimensions as shown in Figure 2-3, or use the base of the inverter as a template to mark your mounting screw locations. After marking the mounting screw locations, mount the unit with appropriate mounting hardware.

* Noncombustible surface – A surface made of material that will not ignite, burn, support combustion, or release ﬂ ammable vapors when subjected to ﬁ re or heat as per the ASTM E136 standard. For the most part, these are materials that are largely comprised of inorganic matter such as stone, steel, iron, brick, tile, concrete, slate, and glass. Avoid common building materials such as gypsum board, painted surfaces, wall coverings, and all types of wood. Note: Sensata provides a noncombustible backplate for mounting the inverter.

2.3 Wiring the Inverter – General Requirements

This section describes the requirements and recommendations for wiring the ME-G Series inverter/ charger. Before wiring the ME-G inverter/charger, carefully read all instructions.

Wiring should meet all local codes and industry standards, and be performed by qualiﬁ ed personnel such as a licensed electrician.

The NEC (National Electric Code, ANSI/NFPA 70) for the United States and the CEC (Canadian Electrical Code) for Canada provide safe wiring standards. The NEC/CEC lists requirements for wire sizes, overcurrent protection, and installation methods/standards.

Inverter/charger systems involve power from multiple sources (inverter, generator, utility, batteries, etc.) which make the wiring more hazardous and challenging. The input/output AC and DC circuits are isolated from the inverter chassis. The inverter system grounding is the responsibility of the installer in accordance with the NEC/CEC and local codes.

WARNING: Ensure all sources of DC power (i.e., batteries) and AC power (utility power or AC generator) are de-energized (i.e., breakers opened, fuses removed) before proceeding—to prevent accidental shock.

2.3.1 Protecting Wire – Conduit Box

The AC and DC wires to and from the inverter must be protected as required by code. Use jacketed wires. Sensata offers DC conduit boxes (ME-CB or MPX-CB) that include the necessary AC and DC inverter breakers.

Info: The strain reliefs can be removed and replaced with 3/4” grommets if you are using either the ME-CB or MPX-CB conduit box, and the AC wires are individual conductors (i.e., not jacketed).

2.3.2 Wiring Requirements

• All conductors that are at risk for physical damage must be protected or placed in a raceway.

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

• Where DC wiring must cross AC or vice-versa, try to make the wires at the crossing point perpendicular (90 degrees) to one another.

• Both AC and DC overcurrent protection must be provided as part of the installation.

• The inverter requires a reliable negative and ground return path directly to the battery.

• Use only copper wires with a minimum temperature rating of 90°C (194°F).

2.3.3 Wire Routing

Before connecting any wires, determine all wire routes to and from the inverter. Conductors passing through walls, bulkheads, or other structural members must be protected to minimize insulation damage, such as chaﬁ ng. During installation, always avoid placing conductors near sources of chaﬁ ng caused by vibration or constant rubbing. Typical routing scenarios are:

• AC input wiring from the main AC panel to the inverter

• AC input wiring from an onboard generator (optional) to the inverter

• DC input wiring from the batteries to the inverter

• AC output wiring from the inverter to the coach’s AC main panel or to dedicated circuits

• Battery Temperature Sensor cable from the inverter to the batteries

• Remote control cable (optional) to the inverter

• Ground wiring to and from the inverter

2.3.4 Torque Requirements

Torque all AC wiring connections to 16 lbf-in (1.8 N-m). Torque DC cable connections from 10 to 12 lbf-ft (13.6 to 16.3 N-m).
