Safety Precautions
• All electrical work must be performed in accordance with local and national electrical codes.
• This product is designed for indoor/compartment installation. It must not be exposed to rain,
snow, moisture, or liquids of any type.
• 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.
• 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 for 12 and 24-volt systems and #2/0 AWG
gauge for 48-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.

Safety 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 2.10
“MMP/Inverter System Grounding” 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 fluid/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. Always 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.

Sûreté de batterie
• Utilisez les outils isolés et faites attention très en travaillant autour des batteries, ils peuvent
produire les courants extrêmement élevés si au sujet dont court-circuité (par exemple,
laissant tomber un outil en métal à travers la borne de batterie), pourrait causer un fiou une
explosion.
• Lisez et suivez les mesures de sécurité du fabricant de batterie avant d’installer l’inverseur et
les batteries. Vérifiez toujours la polarité et la tension appropriées avant de relier les batteries
à l’inverseur. Une fois que les batteries sont reliées à l’inverseur, assurez que l’entretien et les
conditions de remplissage (c.-à-tension de charge et taux de charge) fournis par le fabricant
de batterie sont suivis pour prolonger la vie des batteries et pour empêcher des dommages
aux batteries tout en chargeant.
• Portez la protection d’oeil telle que des verres de sûreté, et l’évitez de toucher vos yeux et
visage en travaillant avec des batteries pour garder n’importe quels fluide/corrosion sur la
batterie des yeux et de la peau contactants. Ayez l’abondance de l’eau doux et du savon
tout près et lavez complètement au cas où l’acide de batterie entrerait en contact avec la
peau, l’habillement, ou les yeux. En cas de l’exposition aux yeux, à l’ood de flils pendant
au moins 15 minutes avec l’attention médicale immédiate d’eau courante et de recherche.
Le bicarbonate de soude neutralise l’électrolyte de batterie d’acide de plomb et le vinaigre
électrolyte neutralise batterie renversée de NiCad et de NiFe ; selon votre type de batterie,
gardez un approvisionnement en main près des batteries.
• Enlevez tous les bijoux tels que les anneaux, montres, bracelets, etc., en installant ou en
exécutant l’entretien sur les batteries et l’inverseur. Une batterie peut produire un court-

1DC Negative to Ground Connection – A busbar connects the DC negative to the
system ground. This busbar can be removed if the primary DC negative-to-ground
connection is made elsewhere in the system (see Section 2.12).
2Mounting Dimples (x4) – These dimples allow the optional ME-BMK-NS (Battery
Monitor Kit without DC shunt) to be installed. For more information on mounting the
battery monitor see Section A3 in Appendix A.
3Mounting Keyholes (x4) – Four keyholes for mounting the enclosure. See Figure 2-4
for size information on these keyholes.
4Inverter AC Wiring Terminal – Terminal for connecting the inverter’s AC input and
output wires.
5AC Breakers – This AC breaker assembly is pre-wired at the factory and consists of the
inverter bypass switch, and the inverter input and output disconnect. These breakers
provide overcurrent protection and a way to disconnect the AC wiring inside the MMP
enclosure. These breakers can also provide overcurrent protection to the AC input source
and output load circuits if the minimum recommended AC wiring sizes are used.
6External AC Wiring Terminal – Terminal for connecting the external AC source (utility/
generator) and the electrical panel that will be powered by the inverter.
7AC Neutral to Ground Connection – A wire (green) connects the AC neutral to the
system ground. This green wire can be removed from the ground busbar if the primary
AC neutral-to-ground connection is made elsewhere in the system (see Section 2.11).
8Ground Busbar – This busbar is connected to the MMP enclosure chassis and is used to
tie AC and DC equipment grounds to a common point.
This busbar has dual hole sizes—three #14 to #1/0 AWG and six #14 to #6 AWG—with
screw type compression terminals (no ring lugs required).
9Inverter’s DC Negative Connection Busbar – Inverter’s DC negative terminal
connects to the top of this busbar.
10 Inverter’s DC Positive Connection Busbar – Inverter’s DC positive terminal connects
to the top of this busbar.
11 DC Shunt – A 500-amp/50 mV shunt installed in the DC negative side that is used to
measure the amperage flowing between the battery and the inverter (and any DC loads
connected). This shunt is pre-installed so that a battery monitor may be easily connected
to display the current flow. See Section A3 in Appendix A for information on installing
and wiring the ME-BMK-NS battery monitor inside the MMP enclosure.
12 Battery Negative Connection – The bottom of the DC shunt is the connection point to
the negative terminal of the battery bank.

Introduction
13 DC Ground Stud – This 5/16” stud is connected to the MMP enclosure chassis and is
provided as a connection point to the DC grounding electrode when the conductor is
larger than #1/0 AWG.
This 5/16” stud also connects to the DC shunt through a busbar and serves as the DC
negative-to-ground connection point. If installing a PV-GFP device, this busbar must be
removed (see Section 2.12).
Note:For ground wires #1/0 AWG or smaller, use the DC negative busbar (Item 20).
14 DIN Rail Track – For installing up to eight 1/2” (12.7mm) wide, DIN rail-mounted,
Q-Frame type breakers. These breakers can be used for connecting DC loads or installing
a PV-GFP device.
15 Mounting Holes (x8) – For installing up to four 1” (25.4mm) wide, back-mounted,
E-Frame type breakers. These breakers can be used for connecting DC loads or installing
a PV-GFP device.
16 Inverter DC Disconnect Breaker – This disconnect is a heavy-duty high amperage circuit
breaker specifically designed for the MMP enclosures. It provides an easy and convenient
way to isolate the inverter from the battery, and meets the NEC/CEC requirements for DC
overcurrent protection when used in accordance with the installation instructions in this
manual. The amperage rating depends on the MMP model (175 or 250 amps).
17 Battery Positive Connection – The bottom of the inverter’s DC disconnect is the
connection point to the positive terminal of the battery bank. The DC disconnect has a
front connected terminal with 3/8-16 captive nuts.
18 Battery Positive Busbar – This busbar is connected to the battery bank positive
through the bottom of the inverter DC disconnect. This busbar is the battery positive
common point for connecting additional DC circuits, such as from the output of a charge
controller or connecting to DC load breakers.
This busbar is rated to handle 120 amps, and has dual hole sizes—two # 14 to #1/0
AWG and five #14 to #6 AWG—with screw type compression terminals (no ring lugs
required).
19 PV Positive Busbar –This busbar provides a convenient connection point inside the
MMP for the positive output from a PV array and the positive input to the PV charge
controller.
This busbar is rated to handle 120 amps, and has dual hole sizes—two # 14 to #1/0
AWG and five #14 to #6 AWG—with screw type compression terminals (no ring lugs
required).
20 DC Negative Busbar –This busbar is connected to the battery bank negative through
the load side of the DC shunt. This busbar is the battery negative common point for
connecting additional DC circuits, such as from the DC negative output of a charge
controller or combining the negatives of DC load circuit breakers.
This busbar is rated to handle 120 amps, and has dual hole sizes—two # 14 to #1/0
AWG and five #14 to #6 AWG—with screw type compression terminals (no ring lugs
required).

Installation
2.2 Location
Refer to the dimensional drawing in Figure 2-2 to determine an appropriate area to install the
MMP enclosure/inverter system. Install it only in a location that meets the following requirements:
Clean and Dry –The MMP/inverter system must be mounted indoors in a relatively cool, clean,
and dry environment.
Ventilation – If a Magnum inverter is installed on the MMP enclosure, the inverter will pull in air
through the intake vents. In order for the inverter to provide full output power and avoid over-
temperature fault conditions, do not cover or block the MMP enclosure ventilation openings or
install it in an area with limited airflow. At the minimum, allow three inches of clearance to the
left and right sides of the MMP enclosure to provide adequate ventilation.
Close to the Battery Bank – The MMP enclosure/inverter system should be located as close to the
batteries as possible. This is to ensure the battery cable length is kept as short as possible. Long DC
wires tend to lose efficiency and reduce the overall performance of an inverter. However, the MMP
enclosure, the inverter, and any other equipment that can spark (or that corrosion could damage)
should not be installed in the same compartment/room as the batteries or mounted where it will
be exposed to gases produced by the batteries. These gases are corrosive and will damage this
equipment; also, if these gases are not ventilated and if allowed to collect, they could ignite and
cause an explosion. Consult your battery supplier for proper installation requirements.
Info: Consult your inverter owner’s manual to determine the proper sized inverter-
to-battery cables for the distance that is used. However, this cable must not be sized
any smaller than the minimum size requirement for the DC disconnect breaker in the
MMP enclosure. The MMP175 models require a minimum 00 (2/0) AWG cable, and the
MMP250 models require a minimum 0000 (4/0) AWG cable.
Safe – Keep any flammable/combustible material (e.g., paper, cloth, plastic, etc.,) that may be
ignited by heat, sparks or flames at a minimum distance of twelve feet away from the MMP/inverter
system. Do not install the MMP/inverter system in any area that contains extremely flammable
liquids like gasoline or propane, or in locations that require ignition-protected devices. Sparks
from relays, circuit breakers, etc., could ignite the fumes or spills.
Accessible – Do not block access to the front of the MMP enclosure. Maintain at least a 36”
(91 cm) clear space in front to access the AC and DC wiring terminals and connections inside the
MMP enclosure, as they will need to be checked and tightened periodically.
2.3 Conduit Knockouts
The MMP enclosure comes standard with knockouts for 1/2”, 3/4”, 1”, 1¼”, 1½”, and 2” conduits.
Figure 2-2 shows the location of these conduit knockouts. The 1/2”, 3/4”, and 1” knockouts are
for the PV array, DC loads, and other smaller input cables. Select the appropriate knockout that
is close to the terminal that the wire will connect to, or whichever one works for the way your
field wiring comes in. The 1½” and 2” knockouts on the bottom of the MMP enclosure are used
to connect to the battery bank.
Info: The knockouts can be easily removed by tapping the edge with a straight bladed
screwdriver and a hammer, then twist out with pliers. Refer to Figure 2-3.
Before removing the appropriate knockouts and mounting the MMP enclosure, think about whether
you are going to use cable clamps or conduit and all the different wiring required, such as:
• Wiring from the MMP enclosure to an AC sub-panel
• Wire runs from the utility and/or a generator to the MMP enclosure
• Battery cable wiring from the battery bank to the MMP enclosure
• Additional wiring from any external DC source (PV, wind, or hydro) to the MMP enclosure
• Small signal wiring (battery sensors, battery monitoring, auto gen starting)
• Attaching lightning arrestors
• PV charge controller wiring
