2.2 Available MPX Models
The three models in the MPX Series are: the MPXS-30D, MPXS-60S, and the MPXD-30D (see Figures 2-3
to 2-5). The MPXS-30D model is designed for use with a single MP enclosure (MPSL-30D and MPSH30D), the MPXS-60S is only used with the MPSL-60S, while the MPXD-30D is designed for use with
a dual MP enclosure (MPDH-30D). Each model comes in a left (L) and right (R) version. The ‘right’
version (MPXS-30D-R, MPXS-60S-R, or MPXD-30D-R) is used when the MPX is mounted to the right
of the MP enclosure, and the ‘left’ version (MPXS-30D-L, MPXS-60S-L, or MPXD-30D-L) is used when
the MPX is mounted to the left of the MP enclosure. The left version differs from the right only in that
the length of the supplied DC cables are different to accommodate the difference in distance from
the MP’s DC breaker to the new installed inverter.
Info: The MPXS-60S model is unique in that it provides #6 AC wiring and a single-pole
60 AAC breaker, rather than the #10 AC wiring and 30 AAC double-pole breaker that
comes with the MPXS-30D and MPXD-30D models.

3.1 Installing the MPX
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 location and application of the installation.
WARNING: This manual does not cover all the relevant safety instructions for your entire
MP/MPX system. Review the safety information on pages 1 and 2 of this manual. Refer
to the MP Owner’s Manual (PN: 64-0028) prior to installing the MPX extension.
CAUTION: The MPX/MP enclosures and the inverters are heavy . Remember to use proper
lifting techniques during installation to prevent personal injury.
3.1.1 Preparation
Before proceeding, read the entire Installation section to determine how you are going to install your
MPX extension. The more thorough you plan in the beginning the more time you will save. Proper
planning will also help you avoid common, costly mistakes.
Required Materials and Tools
Materials
• Conduit, strain-reliefs, and appropriate fi ttings • 1/4” mounting bolts & lock washers
• Electrical tape • Wire ties
• Conductors/cables for wiring
Tools
• Miscellaneous screwdrivers • Insulated pliers • Wire cutters/strippers
• Drill and drill bits • Pencil or marker • Multimeter
• Level • 1/2” wrench • Torx driver (T20,T25)
• Torque wrenches • Ratchet drives
Location
Info: When possible, Magnum Energy recommends that if you are installing only one MPX
it should be mounted to the left of the MP enclosure. Mounting the MPX on the right may
prevent you from adding certain manufacturers’ charge controllers in the future.
Only install your enclosure/inverter system in a location that meets the following requirements:
Clean and Dry - System must be mounted indoors in a relatively cool, clean, and dry en vironment.
Ventilation - If installed on the MP enclosure or MPX, the inverters pull in air through the intake
vents. In order to provide full output power and avoid over-temper ature fault conditions do not cover
or block the MPX/MP enclosures’ ventilation openings, or install it in an area with limited airfl ow. At
the minimum, allow 3 inches of clearance to the left and right sides of the MPX/MP enclosures.
Close to the Battery Bank - Locate system as close to the batteries as possible. This ensures the
battery cable length is kept as short as possible. Long DC wires tend to lose effi ciency and reduce the
overall performance of an inverter. However, the MPX/MP enclosures, 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 battery gases. 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 inverter-to-battery
cable size for the distance that is used. However, this cable must not be sized any smaller
than 0000 (4/0) AWG if the DC disconnect breaker in the MP enclosure will also be used
as the overcurrent device. If a cable smaller than 4/0 AWG is used, an appropriately sized
fuse must be installed to provide overcurrent protection to this smaller cable.

3.0 Installation
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 12 feet away from the MP/inverter
system. Do not install the MPX/MP/inverter system in any area that contains extremely fl ammable
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 your system. Maintain at least a 36” (91 cm)
clear space in front to access the AC and DC wiring terminals and connections inside the MPX/MP
enclosure, as they will need to be checked and tightened periodically.
Removing the MPX’s Front Cover
Remove the front cover on the MPX extension using a T25 Torx screwdriver. The screws are #10-32
x 3/8” Pan head, T25 Torx drive, thread cutting screws and the washers are #10 external tooth Star
washers. You will need to reattach the MPX cover once all wiring is completed and tested.

Info: Identify and remove whatever MPX knockouts you will need for your installation prior
to attaching the MPX to the MP enclosure. It is much easier to do this now rather than once
the MPX is attached.
Figure 3-2, Removing
a Knockout
Remove one of these knockouts in order
to run the communication cables from
the router to the inverters.
Do not remove any these front knockouts if the router* is attached to the MPX
(see also Figure 3-4).
Note: The RTR bracket below is shown
mounted on the right side of the MPX. The
bracket can also be mounted on the left side
of the MPX.
Do not attach the RTR bracket to the MPX/
MP enclosure at this time (the bracket will be
attached later in Section 3.1.8).

3.1.2 Attaching the MPX to the MP Enclosure
The MPX attaches to the MP enclosure. This provides unit stability when the MP enclosure is mounted to a backplate/sheathing, and also ensures good
metal-to-metal contact for grounding the MPX and
the MP enclosure together.
1. On the upper side of the MP enclosure, remove
the side access plate – the side to which you will
attach the MPX (see Figure 3-5).
2. Using the same screw and lock washer (see
Item A), attach the side access plate to the
side of the MPX (opposite the side of the MPX
that attaches to the MP).
Note: Before attaching the MPX to the MP
enclosure you should have already removed
a knockout from the bottom of the MPX (see
Figure 3-3). This knockout is needed for running the communication cables from the router
to the inverters.
Use the supplied (B) #1032 x 3/8” (T25) T orx screw
and #10 lock washer
(Figure 2-2, Items 5 & 6) to
attach the MPX to the MP
enclosure.

3. Use the supplied screw and lock washer (see
Item B) to attach the MPX to the MP enclosure.
The attachment hole is located towards the front
of the (lower) side of the MPX.

3.1.3 Mounting the MP/MPX Enclosure to a Backplate/Wall
The MP enclosure and attached MPX can be mounted on a Magnum backplate or a wall (see the MP
Owner’s Manual for wall requirements).
1. Using eight bolts, screw them halfway into the
backplate/wall in the locations that the MP enclosure and attached MPX will be mounted (align
with each unit’s four keyhole slots).
Note: If you have purchased a Magnum dual
or single backplate, you will be supplied with
the necessary Hex head bolts (1/4-20 x 3/4”) to
mount the MP and MPX units to the backplate.
If you are mounting to a wall, the installer must
provide the appropriate mounting bolts.
2. Hang the MP enclosure and attached MPX onto
the eight bolts using each unit’s keyhole slots
(see Figure 3-6).
3. Tighten the bolts to secure the MP enclosure
and MPX onto the backplate/wall.

3.1.4 Attaching the DC and AC Breakers
Info: The holes on the breaker mounting plate inside the MP enclosure — for Torx screws
that hold the new DC and AC breakers — are NOT pre-threaded. Use a power driver to
screw these self-threading screws into the mounting plate.
WARNING: During normal operation the terminals, busbars, and electrical components
inside the MP enclosure may be energized - DO NOT TOUCH. Disconnect all power sources
before removing the cover.
DC Breaker
CAUTION: The DC break ers must be mounted in a vertical position to meet the specifi ed
trip current and trip delay curve.
The DC breaker is attached within the MP enclosure and functions as the inverter’s DC disconnect switch.
The DC breaker can be used as the battery-to-inverter circuit protection in most installations.
1. Using a T25 screwdriver, remove two of the #10-32 x 3½” Torx screws that secure the existing
DC breaker to the mounting plate – the removed screws should be the two that are adjacent to
where the new DC breaker will be mounted (see Figure 3-7).
2. Place the new DC breaker against the MP’s mounting plate and next to the existing DC breaker
where the two mounting straps are loose.
3. While holding the new DC breaker in place, fi t two new mounting straps over the new DC breaker.
Ensure the holes on the new mounting straps — that are over the new DC breaker — line up with
the holes of the adjacent two existing mounting straps (see Figure 3-8).
4. Insert the two Torx screws that were removed in Step 1 into the aligned holes of the new and
existing mounting straps on the adjacent sides of the breakers, and then tighten to secure the
existing DC breaker. Insert two new #10-32 x 3½” Torx screws into the other side of the new
mounting straps and tighten enough to hold the new DC breaker in place. Do not fully tighten the
screws, that will be done in Step 5 after being aligned.
5. Check for proper breaker alignment by temporarily placing the MP’s front panel co ver over the DC
breakers. If fi t and alignment are correct, tighten all T orx screws to secure the new DC break er.
CAUTION: Be careful not to over-tighten to the point of bending down the tabs on the
mounting straps.

AC Breaker
The AC breaker is attached within the MP enclosure and functions as the inverter’s AC input disconnect switch.
1. While holding the new AC breaker against the MP’s mounting plate, align the breaker’s four mounting holes with the enclosure’s mounting holes (see Figure 3-9). Note: The AC breakers are always
installed in the left enclosure of a MP dual enclosure (see Figure 3-10).
2. Use the supplied four #8-32 x 1/4” T20 screws (Figure 2-2, Item 4) to hold the AC breaker in
place. Do not fully tighten the screws, that will be done in the next step after ensuring proper
alignment with the MP enclosure’s cover.
3. Check the AC breaker alignment by temporarily placing the MP’s front panel cover over the AC
breakers. If the fi t and alignment are correct, tighten all Torx screws to secure the new AC breaker.
Use four #8-32 x ¼”
(T20) Torx screws

3.1.5 Connect and Separate Inverter AC Wires
Prior to mounting the second inverter on the MP enclosure, connect the AC wires provided in the
MPX AC wire kit (see Figure 2-1, Item F and Table 2-1) to the inverter’s AC wiring terminal (see
the inverter owner’s manual or the MP Owner’s Manual for guidance in connecting the AC wires
inside the inverter). Before connecting the AC wires, separate them into two wire bundles (inverter
AC input and inverter AC output) to help ensure they are connected correctly after the inverter is
mounted on the MP enclosure.
It is possible to connect these wires after the inverter is mounted. However, you have more space and
easier access to the wiring terminal when the inverter’s AC wires are connected before mounting –
especially when installing multiple inverters side-by-side on an MP enclosure system. Replace the
AC wiring access plate once you have connected the wires inside the inverter.
3.1.6 Mounting the Second Inverter onto the MPX
The additional inverter fi ts on top the MPX and is secured to the backplate/wall (Figures 3-11 & 3-12).
Note: Before mounting, pull the unconnected ends of the AC wiring outside of the inverter and
through the MPX enclosure (see Figure 3-12).
1. Place the Magnum inverter on top of the MPX.
2. Secure it to the backplate/wall using four Hex head bolts and the inverter’s keyhole slots.
3. Tighten the Hex head bolts to secure the inverter to the backplate/wall.
Note: Prior to mounting, connect the AC input
and output wires within the new inverter (refer
to your inverters owner’s manual), and then
route the wiring through the MPX.

3.0 Installation
Note: Prior to mounting,
connect the AC input and
output wires within each
new inverter (refer to your
inverter owner’s manual),
and then route the wiring
through the MPX.
Figure 3-12, Mounting Multiple Inverters on the MPX
IMPORTANT: If the inverter is ever removed from the top of the MPX for service and the
AC bypass breaker is used to continue to power the inverter loads, attach the knockout plate
(provided with the MP enclosure) to the top of the MPX for use as a safety plate to prevent
accidental access to live electrical circuits inside the MPX.
WARNING: If the knockout plate is used as a safety plate, the battery cables from the
top of the DC disconnect must be prevented from touching the metal knockout plate or
a short circuit to the battery bank may occur – causing lethal currents. Either remove
these cables or isolate them (i.e., using electrical tape/rubber caps), do not rely ONLY
on turning the DC disconnect switch to OFF.
3.1.7 Attaching the Inverter Hood
The inverter hood is designed to prevent objects from falling inside the top vents of the inverter,
which can cause damage. For installations where the inverter is mounted on a vertical surface (DC
terminals facing down) — such as a MP enclosure — the hood must be mounted above the inverter
in order to meet UL regulatory requirements.
Info: The inverter hood does not mount to the inverter chassis, it must be mounted to the
backplate/wall. Mounting bolts are included if a Magnum backplate has been purchased.
If no backplate, the installer must supply the bolts – the mounting slots on the hood will
accept up to a maximum 1/4” screw/bolt.
CAUTION: The inverter hood is not to be used as a drip shield to prevent water drops
from entering the inverter.
Refer to Figures 3-13 & 3-14 to install the hood. The bottom edge of the hood must be mounted
fl ush against the top of the inverter. This is the optimal position for minimizing the risk of objects
falling into the inverter, and at the same time providing the clearance needed for air fl ow from the
top vents of the inverter. Do not place anything on top of the inverter hood that might cause it to
bend downward, or place anything on the sides that might restrict air fl ow through the inverter.
1. Screw two bolts/screws halfway into the backplate/wall where the hood will be mounted.
2. Place the inverter hood on these screws, and then tighten securely.
