1.0 Introduction
How an Inverter/Charger Works
An inverter takes direct current (DC) from your batteries and turns it
into alternating current (AC), like you use at home. With MM Series
models that have the battery charger feature, it also takes alternating
current (when connected to a generator or to shore power) and transforms it into direct current to recharge your batteries.
There are three modes of operation associated with this inverter:
Inverter Mode: DC from the batteries is transformed into AC for
powering your boat or RV accessories.
Transfer Mode: AC is taken directly from shore power (or other AC
sources) and passes through the inverter directly to your RV or boat
accessories.
Charger Mode (not available on all models): The incoming AC from
shore power (or other AC sources) is converted to DC to recharge the
batteries connected to the inverter.
What Appliances will run from a Modifi ed Sine Inverter
Today’s inverters come in two basic output waveforms: modifi ed sine
(which is actually a modifi ed square wave) and pure sine wave. Modi-
fi ed sine wave inverters approximate a pure sine waveform.
The output of a modifi ed sine wave inverter 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 devices may not run
or be damaged by modifi ed sine wave inverters.
Appliances and Run Time
The MM Series inverter can power a wide range of household appliances
including small motors, 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 application, as well as the battery’s capacity and
age. Other factors such as the battery’s state of charge and temperature can also affect the length of time your appliances can run.
Appliances such as TVs, VCRs, stereos, computers, and lights can all
be successfully powered by your inverter. Depending on your inverter
capacity, larger electrical appliances such as coffee pots and hair dryers can be used for short durations. However, loads that are used for
longer periods such as stoves or water heaters can quickly drain your
batteries and are not recommended for inverter applications.
All electrical appliances are rated by the amount of power they consume. The rating is printed on the product’s nameplate label, usually
located on its chassis near the AC power cord. Even though it is diffi cult to calculate exactly how long an inverter will run a particular appliance, the best advice is trial and error. Your MM Series inverter has
a built-in safeguard that automatically protects your batteries from
being over-discharged.

2.0 Installation
Locating and Mounting the Inverter
WARNINGS:
• Do not mount the inverter near any fl ammable or com-
bustible fl uid or components.
• Provide adequate clearance/ventilation to the inverter.
• Mount only on a “non-combustible” surface.
• Maximum ambient temperature around the inverter must
not exceed 77° F (25° C) to meet power specifi cations.
The inverter should only be installed 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. Also, the internal circuit
boards are conformal coated. The above measures are undertaken
to help fi ght the harmful effects of corrosive environments. However,
the life of the inverter is uncertain if used in any of these types of
environments, and inverter failure under these conditions is not
covered under warranty.
Cool - The inverter should be protected from direct exposure to the
sun or any equipment that produces extreme heat. The ambient air
temperature should be between 32° F (0° C) and 104° F (40° C);
realize that the inverter’s output specifi cations are rated at 77° F (25°
C), so the cooler the better within this range.
Ventilated - In order for the inverter to provide full output power and
avoid over-temperature fault conditions; do not cover or block the
inverters ventilation openings, or install this inverter in an area with
limited airfl ow. Allow as much clearance around the inverter’s intake
and exhaust ventilation openings as possible, see Items 12 and 13 in
Figure 3. At the minimum, allow an airspace clearance of 6” (15 cm) at
the front and back, and 3” (7.5 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 vent) and an exhaust opening
on the back side (exhaust vent) of the inverter. This will allow cool air
from the outside to fl ow into the inverter, and heated air to exit away
from the inverter and the enclosure. When mounted in an enclosed
compartment, airfl ow must be at least 59 cfm in order to maintain no
more than a 68° F (20° C) rise in compartment temperature. Minimum
clearances can be reduced if airfl ow is increased, but in no case should
clearance around the inverter be less than 2” (5 cm) on all sides.
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 (60 cm) away from the inverter.
