3.2.3 Wiring the MPXS-60S
The following steps are basic guidelines for installing and connecting the AC, DC, and communication cables for the MPXS-60S.
WARNING: To prevent electrical shock, make sure all AC power (inverter, generator, or
utility) is off before making any AC connections inside the MP enclosure.
MPXS-60S AC Wiring
This section provides information on the AC wiring to/from the MS4024 inverters, and to/from the
main panel and sub-panel. The MPXS-60S kit includes #6 AWG strand B wires for wiring to the AC
terminals in the MP panel. The HOT 1 and HOT 2 wires into/out of the inverter are longer than needed.
This allows you to cut and use the two excess wire lengths (one black and one red, or one black w/
stripe and one red w/ stripe) for routing AC wires from the bottom of the AC breakers to the MP’s
busbar terminals. See Table 2-1 for AC wire size, color, length, and routing location.
Inverter AC Input Wiring (see Figures 3-20a and 3-21a)
LEG 2 AC Input Wiring
1. Route and attach a red wire from the top terminal of the MP enclosure’s AC input breaker (B1)
to the HOT 2/LEG 2 inverter’s AC HOT 1 IN and AC HOT 2 IN terminals.
2. Route and attach a white wire from the MP enclosure’s AC NEUTRAL busbar to the HOT 2/LEG
2 inverter’s AC NEUTRAL terminal.
3. Route and attach a green wire from the MP enclosure’s GROUND busbar to the HOT 2/LEG 2
inverter’s AC GROUND terminal.
LEG 1 AC Input Wiring
NOTE: The LEG 1 AC input wiring is shown in the MP enclosure owner’s manual.
Inverter AC Output Wiring (see Figures 3-20a and 3-21a)
LEG 2 AC Output Wiring
1. Route and attach a red w/white stripe wire from the MP enclosure’s INV HOT 2 OUT busbar to
HOT 2/LEG 2 inverter’s AC HOT 2 OUT and AC HOT 1 OUT terminals.
2. Route and attach a white wire w/black stripe from the MP enclosure’s AC NEUTRAL busbar to
HOT 2/LEG 2 inverter’s AC NEUTRAL terminal.
LEG 1 AC Output Wiring
NOTE: The LEG 1 AC output wiring is shown in the MP enclosure owner’s manual.
NOTE: For the full 60 amp AC pass-thru on MS4024 model inverters, the inverter’s HOT 1 and HOT
2 terminals must be wired together. Each terminal (separately) is only rated for 30 amp AC. See
Figure 4-1 in the MP manual (PN: 64-0028), or refer to your MS Series owner’s manual for more
info on AC wiring.

Figure 3-20a, Inverter AC Input and Output Wiring Diagram
Info: When wiring the MS4024 (or any other MS Series inverter), both the inverter input
and output neutral wires must be connected to a AC NEUTRAL busbar inside the MP enclosure. This is because — depending on the inverter’s operating mode — the inverter’s
input and output neutral terminals may not be connected together (i.e., inverter’s neutrals are not connected when “inverting”, and are combined when “charging”).
NOTE: Because a neutral to ground connection is also made in the MP enclosure, the neutral to
ground connection inside the MS4024 must be disconnected. Refer to your MS4024 owner’s manual
for information on how this is done.

MPXS-60S DC Wiring
This section covers the DC wiring to/from the inverters, and from the battery bank.
WARNING: During normal operation, the terminals, busbars, and electrical components
inside the MP enclosure may be energized – DO NOT TOUCH.
WARNING: Disconnect all power sources before removing the cover. Even though DC
voltage is “low voltage”, significant hazards may be present, particularly from short circuits of the battery system.
CAUTION: DO NOT connect the battery cables to the battery bank until all wiring to the
inverters and inside the MP/MPX enclosure is complete and the correct DC voltage and
polarity have been verified.
Installing the DC Cables From the Inverters to the MP (see Figure 3-21c)
IMPORTANT: Coordinate the DC wiring to each inverter from each DC breaker such that the
far left inverter is connected to the far left breaker (HOT 2/LEG 2 DC breaker), and the second
inverter is connected to the second DC breaker (HOT 1/LEG 1 breaker), and so on.
1. Route a DC positive cable (red) from each inverter into the MP enclosure.
2. Connect the end of the DC positive cable (red) to the inverter’s positive DC terminal.
3. Connect the other end of the DC positive cable (red) to a DC circuit breaker’s top terminal.
4. Route a DC negative cable (black) from each inverter into the MP enclosure.
5. Connect the end of the DC negative cable (black) to the inverter’s negative DC terminal.
6. Connect the other end of the DC negative cable (black) to the top of the DC shunt’s busbar.
7. Route an appropriately sized DC equipment ground wire from each new inverter’s DC GROUND
terminal to the DC GROUND busbar in the MP enclosure.
8. Verify all DC connections are torqued from 10 to 12 ft lbf (13.6 to 16.3 N-m).
9. Once the DC connections are correctly wired and tested, coat the terminals with an approved
anti-oxidizing coating.
Installing the DC Cables From the Battery Bank to the MP Enclosure (see Figure 3-21d)
IMPORTANT: Damage may occur if DC power is connected to the MP enclosure before the
Communication wiring is completed. DO NOT connect the DC cables from the MP enclosure
to the battery bank until: 1) all DC, AC, and Comm wirings are completed, 2) the correct DC
and AC overcurrent protection have been installed and, 3) the correct DC voltage and polarity
have been verified.
WARNING: Ensure all AC and DC breakers are switched OFF before connecting or disconnecting
the battery cables, and that all AC and DC power is disconnected from the inverter.
WARNING: Lethal currents will be present if the positive and negative cables attached
to the battery bank touch each other. During the installation and wiring process, ensure
the cable ends are insulated or covered to prevent touching/shorting the cables.
CAUTION: The Magnum inverter is NOT reverse polarity protected, if this happens the
inverter will be damaged and will not be covered under warranty. Before making the
final DC connection from the MP enclosure down to the battery bank, verify the correct
battery voltage and polarity by using a voltmeter. If the positive (+) terminal of the battery is connected to the negative (–) busbar of the MP enclosure and vice versa, severe
damage will result. Ensure the cables are color-coded to avoid polarity confusion.
1. Route a DC positive battery cable (red) from the battery bank through the bottom of the MP
enclosure for each inverter.
2. Connect the end of the DC positive battery cable (red) to the DC circuit breaker’s bottom
battery positive connection.

3. Route a DC negative battery cable (black) from the battery bank thru the bottom of the MP enclosure
for each inverter.
4. Connect the end of each DC negative battery cable (black) to the battery negative connection (DC
shunt’s bottom busbar).
5. Route an appropriately sized DC equipment ground wire from the ground terminal in the battery
bank enclosure to the DC ground terminal in the MP enclosure.
6. Route an appropriately sized DC grounding wire (green or bare wire) from the DC GROUND busbar
in the MP enclosure to the system ground (see the MP owner’s manual for information on sizing and
connecting the system ground wire).
7. Ensure the DC wire connections (to the inverter, DC circuit breaker, and DC shunt) are flush on the
surface of the DC terminals and the hardware used to hold these connections are stacked correctly
(see Figure 3-17); and then securely tighten these connections.
IMPORTANT: Only after the entire installation is complete and all connections are verified,
should the DC circuit breaker be closed to provide power to the inverters.
MPXS-60S Communication Wiring
Each MPXS-60S kit includes a remote cable and a stacking cable. The MP enclosure comes with an
extension cable for connecting the inverter to a Battery Temperature Sensor (BTS).
Connecting Remote Cables to Remotes (see Figure 3-21e)
1. Using the supplied RJ11 remote cables, route a cable from each inverter to each remote control
(or router).
2. Connect one end of each remote cable to the Remote port (blue label) on each installed inverter.
3. Connect the other end of each remote cable to a separate remote control.
Connecting Inverters Using Series Stacking Cable (see Figure 3-21e)
1. Using the supplied stacking cable, route the cable from the HOT 2/LEG 2 inverter’s Stack port
(red label) through the MPX and MP enclosure to the HOT 1/LEG 1 inverter’s Stack port.
2. Connect the two ends of the series stacking cable to the Stack port of the two installed inverters.
Battery Temperature Sensors (see Figures 3-21e)
The Battery Temperature Sensor provides the inverter with precise battery temperature information that enables the batteries to be correctly charged under extreme temperature changes. If the
BTS is not installed and batteries are subjected to large temperature changes, battery life may be
shortened.
1. Using the supplied extension cables, route a cable from the each inverter through the MP enclosure to a BTS.
Info: When the inverters are installed in a series, each inverter should have a BTS connected to its Battery Temp Sensor port.
2. Connect one end of each extension cable to the Battery Temp Sensor port (yellow label) on each
inverter.
3. Connect the other end of each extension cable to the RJ-11 connector on a separate BTS.
Connecting the DC Cables from the MP Enclosure to the Battery Bank
Once all the wiring (AC, DC, and Comm) is completed, connect the DC cables from the MP enclosure
to the battery bank.

8. Verify all DC connections are torqued from 10 to 12 ft lbf (13.6 to 16.3 N-m).
9. Once the DC connections are correctly wired and tested, coat the terminals with an approved
anti-oxidizing coating.
Installing the DC Cables From the Battery Bank to the MP Enclosure (see Figure 3-22d)
IMPORTANT: Damage may occur if DC power is connected to the MP enclosure before the
Communication wiring is completed. DO NOT connect the DC cables from the MP enclosure
to the battery bank until: 1) all DC, AC, and Comm wirings are completed, 2) the correct DC
and AC overcurrent protection have been installed and, 3) the correct DC voltage and polarity
have been verified.
WARNING: Ensure all AC and DC breakers are switched OFF before connecting or disconnecting
the battery cables, and that all AC and DC power is disconnected from the inverter.
WARNING: Lethal currents will be present if the positive and negative cables attached
to the battery bank touch each other. During the installation and wiring process, ensure
the cable ends are insulated or covered to prevent touching/shorting the cables.
CAUTION: The Magnum inverter is NOT reverse polarity protected, if this happens the
inverter will be damaged and will not be covered under warranty. Before making the
final DC connection from the MP enclosure down to the battery bank, verify the correct
battery voltage and polarity by using a voltmeter. If the positive (+) terminal of the battery is connected to the negative (–) busbar of the MP enclosure and vice versa, severe
damage will result. Ensure the cables are color-coded to avoid polarity confusion.
1. Route a DC positive battery cable (red) from the battery bank through the bottom of the MP
enclosure for each inverter.
2. Connect the end of the DC positive battery cable (red) to the DC circuit breaker’s bottom
battery positive connection.

3. Route a DC negative battery cable (black) from the battery bank thru the bottom of the MP enclosure
for each inverter.
4. Connect the end of each DC negative battery cable (black) to the battery negative connection (DC
shunt’s bottom busbar).
5. Route an appropriately sized DC equipment ground wire from the ground terminal in the battery
bank enclosure to the DC ground terminal in the MP enclosure.
6. Route an appropriately sized DC grounding wire (green or bare wire) from the DC GROUND busbar
in the MP enclosure to the system ground (see the MP owner’s manual for information on sizing and
connecting the system ground wire).
7. Ensure the DC wire connections (to the inverter, DC circuit breaker, and DC shunt) are flush on the
surface of the DC terminals and the hardware used to hold these connections are stacked correctly
(see Figure 3-17); and then securely tighten these connections.
IMPORTANT: Only after the entire installation is complete and all connections are verified,
should the DC circuit breaker be closed to provide power to the inverters.
MPXD-30D Communication Wiring
Each MPXD-30D kit includes a remote cable and a stacking cable for connecting to a router. The
Magnum router comes with two CAT 5 cables and two RJ11 communication cables. The MP enclosure
comes with an extension cable for connecting the inverter to a Battery Temperature Sensor (BTS).
Connecting Remote Cables to the Router (see Figure 3-22e)
1. Using the supplied RJ11 remote cables, route a cable from each inverter to the attached router.
2. Connect one end of each remote cable to the Remote port (blue label) on each installed inverter.
3. Connect the other end of each remote cable to its respective port (P1-P6) on the router.
Info: It is recommended that the Master inverter be connected to Port 1, Slave 1 to Port 2
etc., in order to keep track of which inverter is displayed on each port.
Connecting Stacking Cables to the Router (see Figure 3-22e)
1. Using the supplied stacking (CAT 5) cables, route a cable from each inverter to the attached router.
2. Connect one end of each stacking cable to the Stack Port (red label) on each installed inverter.
3. Connect the other end of each stacking cable to its respective CAT 5 port on the router (MA,
SL1, SL2, and SL3 ports for the appropriate number of installed inverters).
Info: At least one CAT 5 cable must be plugged into the router’s MA port in order for the
router to operate any inverters.
Battery Temperature Sensors (BTS) (see Figures 22e)
The Battery Temperature Sensor provides the inverter with precise battery temperature information that enables the batteries to be correctly charged under extreme temperature changes. If the
BTS is not installed and batteries are subjected to large temperature changes, battery life may be
shortened.
1. Using the supplied extension cable, route it from the Master inverter through the MPX and MP
enclosure to the battery bank.
2. Connect one end of the extension cable to the Battery Temp Sensor port (yellow label) on the
Master inverter.
3. Connect the other end of the extension cable to the RJ-11 connector on a BTS (connected to
the battery bank).
Connecting the DC Cables from the MP Enclosure to the Battery Bank
Once all the wiring is completed, connect the DC cables from the MP enclosure to the battery bank.
