Introduction
The MM-R remote allows you to turn the inverter on and off (ON/OFF), and
provides three LED indicators for: inverter status (INVERT), status of any
external AC power (AC IN), and to alert you of any faults (FAULT).
The MM-RC remote includes the remote ON/OFF switch and the same three
LED indicators that the MM-R has, as well as three additional LED indicators
for charger status (BULK, ABSORB, FLOAT).

Installation
Before proceeding, read the entire Installation section to determine how best
to install your remote. The more thorough you plan in the beginning, the
better your inverter needs will be met.
Installation Guidelines
• Before connecting any wires determine the remote’s cable route
throughout the home or vehicle/boat, both to and from the inverter.
• Always check for existing electrical, plumbing, or other areas of potential
damage BEFORE drilling or cutting into walls to mount the remote.
• Make sure all wires have a smooth bend radius and do not become kinked.
• If installing this remote in a boat, RV, or truck ensure the conductors
passing through walls, bulkheads, or other structural members are
protected. This minimizes insulation damage (such as chafing) which can
be caused by vibration or constant rubbing.
Unpacking and Inspection
Carefully remove the MM-R or MM-RC remote from its shipping container and
inspect all contents. Verify the following items are included:
• MM-R or MM-RC remote display • Bezel
• 25’ Communication cable • Two Phillips screws
• MM-R/MM-RC Instruction Sheet
If items appear to be missing or damaged, contact your authorized Magnum
dealer or Sensata Technologies. Save your proof-of-purchase as a record of
ownership; it is needed if the unit requires in-warranty service.

Connecting the Communication Cable
The MM-R and MM-RC each come with a cable to enable communication
between the inverter and the remote. The communication cable is a flat 25’
telephony standard with 6P4C (6-position, 4-conductor) connectors on each
end. When the 6P4C connectors are held as shown in Figure 3 below, the
color of the conductors in each connector is the same from top to bottom.
Info: The 25’ cable is long enough for most applications. If additional
cable length is needed, the cable can be extended up to 50’ using a
standard phone cable and a female-to-female connector.
Figure 4, Communication Cable Connections
Connecting the MM-R/MM-RC to a Magnum Inverter
One end of the remote cable is connected to the RJ11 jack on the rear of the

Operation
This section explains how to use the MM-R/MM-RC remotes when operating
an inverter/charger. It provides information on the ON/OFF button and the
LED indicators—that are used to show the operational status of the inverter/
charger and to assist you with troubleshooting.
MM-R/MM-RC Remotes
ON/OFF Power Switch
The remote’s ON/OFF power switch is a momentary pushbutton that duplicates
the ON/OFF switch on an inverter. This switch also allows additional changes
to be made while in Invert mode or while charging.
When the inverter is first connected to the batteries, the inverter and remote
go through an internal 10-second start-up test. After this test is completed,
the remote’s ON/OFF switch can be pressed to turn on the inverter. Once
the inverter has been turned on, momentarily pressing the remote’s ON/
OFF switch alternately turns the inverter off and on. The remote’s ON/OFF
switch can be used to enable or disable Search mode. While in Invert mode,
pressing and holding this switch for three seconds causes Search mode to
alternate between disabled (inverter always on—INVERT LED always on)
and 5W (inverter looking for at least a 5-watt load to turn on and start
inverting—indicated by the INVERT LED blinking x1/sec).
MM-RC only: The MM-RC remote’s ON/OFF switch can also be used to
disable the charger (Charger Standby) so that all the incoming power can be
used exclusively for the AC loads. To put the inverter into Charger Standby,
wait until the charger comes on [indicated by one of the charge indicators
(BULK, ABSORB, FLOAT)being on], then press and hold the remote’s ON/OFF
switch for three seconds. When this happens, the charging indicators on the
MM-RC remote will go off. To come out of Charger Standby and activate the
charger, press and hold the remote’s ON/OFF switch for three seconds again.
When the charger is again activated, one of the MM-RC remote’s charging
indicators comes on to show the current charge stage.
WARNING: When any external AC power is passing through the
inverter and present on the output, pressing the remote’s ON/OFF
switch will not remove this AC power on the inverter’s output.
INVERT LED (green)
• On (solid)
– and the AC IN LED is off. The inverter is on. It is using energy from
the battery to supply AC power to the loads connected to the inverter.
– and the AC IN LED is on (solid). The inverter is in Standby mode. The
external AC power (utility/shorepower or generator) connected to the
inverter’s input is passing through the inverter to power the AC loads.
The inverter automatically turns on to power the AC loads if the external
AC power is lost or disconnected.
• Blinks On (once every second) – inverter is in Search mode. The AC load
is below the remote’s Search Watts default setting.
• Off – inverter is disabled. The inverter is not on, or will not come on if
AC power is lost or disconnected.
AC IN LED (green)
• On (solid) – external AC power (utility/shorepower or generator) is
connected to the inverter’s input and passing through the inverter to
power the AC loads connected to the inverter’s output.

MM-R/MM-RC Remotes Instruction Sheet

• Blinking On (once every second) – external AC power is detected on
the inverter’s input, but not actively being used. Either: 1) The AC
input is being qualified (takes approximately 15 seconds); or, 2) The
input AC voltage is low. Ensure the incoming AC voltage is >80 volts
(VAC Dropout default).
• Off – no external AC power is detected on the inverter’s input.
FAULT LED (red)
Under normal operating conditions, the remote’s FAULT indicator will be off.
If there is a fault condition, this LED will blink differently for each specific
fault to help troubleshoot the inverter. Monitor the FAULT LED for at least
10 seconds and count the number of blinks that occur every four seconds to
determine the particular reason for the shutdown. Once you have identified
and cleared the fault, the inverter can be turned on. Refer also to the
Troubleshooting section of your inverter owner’s manual.
• Blinks On (1 time every 4 seconds) – Low Battery Voltage; the battery
voltage level has dropped below the LBCO default setting. Your batteries
need to be charged—this fault condition automatically clears when the
battery voltage is >12.5 VDC, or the inverter begins charging.
• Blinks On (2 times every 4 seconds) – High Battery Voltage; the
battery voltage is above 15.5 VDC. Reduce or turn off the external
charging source to bring the battery voltage down.
• Blinks On (3 times every 4 seconds) – Over-temperature Condition;
the internal temperature of the inverter has risen above acceptable
limits. This may be caused by loads too great for the inverter to operate
continuously, or by lack of ventilation to the inverter. When the unit has
cooled, it automatically resets and resumes operation.
• Blinks On (4 times every 4 seconds) – AC Overload; the inverter has
turned off because the connected loads are larger than the inverter’s
output capacity, or there is a short on the output wiring. The inverter
can be restarted after the AC loads are reduced, or the wiring short has
been removed. To restart the inverter, momentarily press the ON/OFF
button on either the inverter or the remote.
• Blinks On (5 times every 4 seconds) – Internal Fault; the inverter
has turned off because it has detected an internal problem. To clear
this fault, the inverter will need to be reset by: 1) Pressing and holding
the inverter’s ON/OFF switch for 15 seconds (the INV LED must begin
to rapidly flash); or, 2) Disconnect all DC power to the inverter for
at least 15 seconds, and then reconnect. After resetting the inverter,
momentarily press the inverter’s ON/OFF switch and verify the fault has
cleared. If the internal fault remains, the inverter requires service at an
authorized repair facility.
MM-RC Remotes Only
BULK LED (yellow)
• On (solid) – Bulk Charging; the charger is delivering maximum current
to the batteries. The charger will remain in bulk charge until the absorb
voltage (14.5 VDC) is reached—see Table 1-1.
• Blinks On (1 time every 4 seconds) – Charger Back-off (while in
Bulk mode); charger current is reduced. This occurs if: 1) The internal
temperature is very hot (charger reduces charge rate to maintain
temperature) or, 2) The AC input voltage has fallen below 85 VAC
(charger reduces charge rate to help stabilize the incoming AC voltage).
• Off – the charger is not in Bulk Charge mode.

MM-R/MM-RC Remotes Instruction Sheet

ABSORB LED (yellow)
• On (solid) – Absorb Charging; the charger is in the Constant Voltage
stage and begins once the bulk voltage has been reached. The DC
charging current starts to taper down to maintain the Bulk voltage
setting. Absorb Charging time is based on the inverter’s default AHr size.
• Blinks On (1 time every 4 seconds) – Charger Back-off (while in Absorb
mode); the charger current is reduced. This occurs if: 1) The internal
temperature is very hot (charger reduces the charge rate to maintain
temperature) or, 2) The AC input voltage has fallen below 85 VAC (charger
reduces the charge rate to help stabilize the incoming AC voltage).
• Off – the charger is not in Absorption Charge mode.
FLOAT LED (green)
• On (solid) – Float Charging; at the end of the Absorb Charging time,
the charger reduces the charge voltage to maintain the batteries at the
float voltage (13.5 VDC)—see Table 1-1.
• Blinks On (1 time every 4 seconds) – Charger Back-off (while in Float
mode); charger current is reduced. Occurs if: 1) The internal temperature
is very hot (charger reduces the charge rate to maintain temperature)
or, 2) The AC input voltage has fallen below 85 VAC (charger reduces
the charge rate to help stabilize the incoming AC voltage).
• Blinks On (2 times every 4 seconds) – Full Charge; monitors the battery
voltage to determine when to continue charging. After four hours in the
Float Charge mode, the charger turns off and goes to Full Charge mode.
If the battery voltage drops to 12.7 VDC, the charger automatically
initiates another float charge.
• Off – the charger is not in Float Charge mode.
Factory Default Settings
When connected to an inverter, the remote’s settings override the default
settings (see Table 1) in the inverter. The settings in the remote are saved
in the remote’s non-volatile memory, and will be used—even if DC power to
the inverter is lost—as long as the remote is connected.
