Overview
1.0 Overview
The ME-ARC remote control allows you to monitor and customize the operating parameters for
your Magnum inverter/charger. This remote can be used on all Magnum inverter/charger models
so there is no cross-platform confusion.
The ME-ARC50 comes standard with a 50-foot, 4-conductor (twisted-pair) telephone cable and
includes non-volatile memory (preserves adjustable settings, even if power to the remote or in-
verter is removed).
Info: This manual is for a ME-ARC with software version 4.0 or higher; see the TECH:
02 Versions section on page 36 for information on how to determine your version level.

Installation
2.0 Installation
Review this section and the Important Product Safety Instructions on page ii before proceeding
with the installation of your remote.
WARNING: Installations should be performed by qualified personnel, such as a licensed
or certified electrician. The installer determines which safety codes apply and ensures
all applicable installation requirements are followed. Applicable installation codes vary
depending on the specific location and application.
CAUTION: When connecting battery power to the inverter, all battery negative
connections must be connected prior to the battery positive connections. When removing
battery power from the inverter, the battery positive should be removed before any
battery negative connections are disconnected. This prevents any communication chips/
lines from becoming the DC return path to the battery—causing permanent damage to
all connected accessories.
Summation: Ensure all battery negative circuits are always connected before connecting
or disconnecting battery positive.
2.1 Pre-Installation
Before proceeding, read the entire Installation section to determine how best to install your ME-
ARC remote. The more thorough you plan in the beginning, the better your inverter needs will
be met.
2.1.1 Installation Guidelines
• Before connecting any wires determine the remote’s cable route throughout the home or ve-
hicle/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.
2.1.2 Unpacking and Inspection
Carefully remove the ME-ARC remote from its shipping container and inspect all contents. Verify
the following items are included:
• The ME-ARC remote display • Bezel • 50’ remote cable
• Eight #8 x 3/4 Phillips screws • ME-ARC Owner’s Manual
If items appear to be missing or damaged, contact your authorized Magnum Energy dealer or
Magnum Energy.
IMPORTANT: Save your proof-of-purchase as a record of your ownership; it is needed if the unit
should require in-warranty service.
2.1.3 Tools Required
Installing the remote control is simple and requires the following tools:
• Phillips screwdriver • Level • Drill
• Cut-out tool (knife/saw) • Pencil • Drill bit (7/64”)

Installation
2.2 Connecting the Remote Cable
The ME-ARC comes with a remote cable to enable communication between the inverter and the
remote. The cable is a 50-foot, 4-conductor, round twisted-pair, telephony standard with 6P4C
(6-position/4-conductor) connectors on each end. When the 6P4C connectors are held side by
side with both of the connector tabs facing the same way, the color of the conductors in each
connector is the opposite from top to bottom (as shown in Figure 2-1).
Info: This cable has twisted-pair cabling which is a common form of wiring in which
two conductors are wound around each other for the purposes of canceling out
electromagnetic interference (known as “crosstalk”).
Note: The remote cable can be extended up to a length of 200 feet without data degradation.

2.4 Mounting the ME-ARC Remote
The ME-ARC can either be flush mounted (through an opening in the wall), or surface mounted
using the provided bezel. Find a location that is clean, dry and protected. Allow room to access
the remote’s SELECT knob and to view the LEDs/display.
CAUTION: Ensure that no AC power is connected to the inverter, and then according
the your inverter owner’s manual correctly connect the inverter to the batteries.
CAUTION: Always check for hidden electrical wires, pipes and cables BEFORE drilling,
cutting, or screwing into walls or cabinets.
2.4.1 Flush Mount Installation Procedure
To flush mount, the wall opening must have at least a 2” (5 cm) depth to allow room for the re-
mote and the cable.
1. Cut an opening in the wall (Figure 2-5). Ensure there are no openings around the display
and enough material for the screws to secure the unit.
2. Drill four pilot holes for the #8-32 screws that will attach the remote to the wall (refer to
Figure 2-3 for hole locations and dimensions).
3. Route one end of the cable through the wall cutout to the inverter/charger, and then plug
it into the RJ11 REMOTE port (blue label) on the inverter/charger—inverter has DC power,
but is OFF. See Figure 2-2.
4. Take the other end of the remote cable and while plugging it into the back of the ME-ARC,
view the remote’s display to ensure the Power-up Self Test initiates (see Section 2.5).
5. If the self test is successful, secure the ME-ARC to the wall using four of the supplied Phillips
screws. If the self test is unsuccessful, refer to the Troubleshooting section.

2.4.2 Surface Mount Installation Procedure
To surface mount, you must use the supplied bezel (Figure 2-4).
Info: The bezel has tabs at the bottom and side that are made with thinner material
(Figure 2-4). They can be cut or broken out to allow the cable to be routed downward
or to the side (Figure 2-6).
1. Using the bezel as a template, mark on the wall the location of the four bezel mounting
screws, and then drill pilot holes for the #8-32 screws.
2. Cut/break the appropriate tab on the bezel for the planned route of the remote cable.
3. Pull the cable through the bezel and place the bezel side with the removed tab over the cable
against the wall.
4. Position the bezel over the drilled mounting holes, and then screw the bezel to the wall using
four of the supplied Phillips screws (Figure 2-6).
5. Route the other end of the cable to the inverter/charger, and then plug it into the inverter’s
RJ11 REMOTE port (blue label)—inverter has DC power, but is OFF. See Figure 2-2.
6. Take the other end of the cable and while plugging it into the back of the ME-ARC, view the
remote’s display to ensure the Power-up Self Test initiates (see Section 2.5).
7. If the self test is successful, secure the ME-ARC to the bezel using four of the supplied Phillips
screws. If the self test is unsuccessful, refer to the Section 6.0 “Troubleshooting”.

2.5 Power-up Self Test
Info: All power to operate the remote control is provided by the inverter/charger
through the remote cable.
When the ME-ARC is first connected to an inverter, a power-up self test is initialized. During the
self test, the LCD automatically displays in sequence:
• “MAGNUM ENERGY Self Test”, then
• “(C)2010-2013, Connecting to...”, and then
• “ME-ARC V 4.0, INV/CHG V #.#”
The remote’s LEDs also change with the screens (see Figure 2-7).

Setup
3.0 Setup
When the remote is connected to a Magnum inverter/charger, the settings in the remote control
determine the inverter/charger’s operating parameters. The default settings in the remote con-
trol are adequate for most installations (see Table 3-3); however, you have the option to change
some of the operating parameters. This section shows you how to navigate the remote and gives
you an understanding of the function of each adjustable setting.
3.1 Navigating the Remote
The ME-ARC has menu items and adjustable settings that provide the ability to configure your
inverter/charger to your specific parameters.
Info: See Figures 4-1 through 4-5 for complete maps of the inverter/charger’s menu
items and adjustable settings.
Familiarize yourself with the display and controls on the remote’s front panel that are used to

3.2 Remote Buttons and Menu Items
The five menu buttons (FAVS, CTRL, METER, SETUP, or TECH) allow the inverter/charger system
to be configured to your specific preferences. These buttons also allow you to access menu items
that can help with monitoring and troubleshooting your system. Refer to Figure 3-2 for an ex-
ample on how to navigate the remote.
This section covers each menu button’s function and its various configurable settings. This helps
optimize the operation of the inverter/charger.
3.2.1 FAVS Button and Menus
The FAVS (FAVORITES) button is similar to a Favorites button on your TV remote. It enables you
to store the most frequently used menu items for quick reference, or to make easy changes to the
system. The menu items stored under the FAVS button should be those menus most often used.
The FAVS button has five factory-stored default menu items. You can also access these menu
items using the SETUP and CTRL buttons to make changes. Before changing the default FAVS
menu items, it is suggested that you thoroughly review all the menu items on the menu map (see
Figures 4-1 through 4-5) and make a short list of the items you think you will use most often.
Once you decide which five items you would like to make as your favorites, determine the order
in which those menus are to appear under the FAVS button. This is important since you will assign
a FAVS position (F1-F5) for each menu item you select.
Menu items can be changed at any time under the FAVS button. Navigate to a menu item that you
would like to set as a favorite, then push and hold the FAVS button for three seconds. The screen
displays “Select FAV: F1” on the bottom line. Rotate the SELECT knob to select the location for
the menu item (i.e., F1 - F5). Once you have decided the location for the menu item, press the
SELECT knob to save that menu item at the selected FAVS location. Repeat as necessary to save
additional menu items.
Info: The FAVS button can be used to store menu items that would otherwise not be
accessible after a PIN has been set for the SETUP menu. See the TECH: 05 SETUP PIN
section on page 38 for information on setting a security PIN.
Info: Menu headings cannot be selected and stored in FAVS, only menu items. Menu
headings are identified with a number. Menu items are identified by a number followed
by a letter. See examples below.
Info: If the menu selected to be stored under the FAVS button is not a valid option, the
remote displays “Cannot be FAV”.

• FAVS: F3 AC Input Amps – This is the F3 default (FAVS #3). Refer to the SETUP: 03A AC
Input Amps menu item on page 24 for information on how to adjust the AC Input setting.
• FAVS: F4 Battery Type – This is the F4 default (FAVS #4). Refer to the SETUP: 03C Battery
Type menu item on page 26 for information on how to set the battery type.
• FAVS: F5 Gen Control – This is the F5 default (FAVS #5). Refer to the CTRL: 03 Gen Control
menu on page 72 for information on how to use the Gen Control function.
Info: F5 Gen Control is a menu heading. It provides easy access to turn the generator
on and off. If another menu item is saved in the F5 location, the only way to bring Gen
Control back into the F5 location is to reset the remote to its factory defaults using the
TECH: 08 Load Defaults menu (page 39).

3.2.2 CTRL (Control) Button and Menus
The CTRL button accesses the 01 ACIn Control, 02 CHG Control, 03 Gen Control and 04 PT Con-
trol menus.
Info: An AGS controller or PT charge controller must be connected in order for those
device-specific menus under the 03 Gen Control or 04 PT Control settings to display,
respectively—unless the TECH: 07 Show all Menus menu has been set to “YES”. Refer
to Section 3.2.5 for more information on the TECH 07 menu. Otherwise, “No AGS
Present” appears on the 03 Gen Control screen and “No PT Present” appears on the 04
PT Control screen when you press the SELECT knob from these menus.
The CTRL button gives you quick control of some of the main functions of the inverter/charger
without having to access the SETUP button’s menus in order to change the operation of the in-
verter/charger (generator and charge controller also if connected). Once the settings have been
programmed in the SETUP menus, the features can then be enabled using the CTRL button.
Example: The SETUP: 02C AC In - Time setting is used to set what time of day (e.g., 12AM to
8AM) you want the inverter to connect to the incoming AC. Once the time is set, use the CTRL
button to access the Set ACIn Control menu item and select Time Connect. When Time Connect
is selected, the inverter/charger will only connect to AC when the time is between 12AM and 8AM.
Info: If a ME-ARC remote is connected to a parallel system with a ME-RTR, it acts like a
‘display only’ device with limited user controls. When the ME-ARC is directly connected
to either the inverter or ME-RTR, the CTRL button function of the ME-ARC is defeated.
The ME-ARC however, does contain the 03 Gen Control selection in the FAVS menu.
The generator can be controlled via the ME-ARC through the FAVS menu, but not
through the CTRL menu.

CTRL: 01 ACIn Control
01 ACIn Control menu has four different conditions in which the inverter/charger will connect to
an incoming AC power source. Only one may be selected at any one time—multiple conditions can
be enabled, but only one can be active.
Info: Before the inverter allows the AC input to connect to the AC source (grid or
generator), the incoming AC must be qualified by the inverter/charger (voltage is
below the high AC input requirements, above the SETUP: 03B VAC Dropout setting, and
between 50 Hz to 70 Hz for domestic models—40 to 60 Hz for export models).
Info: The top line of the LCD display alternates the inverter/charger status with a
secondary AC IN status when AC is present (not connecting as a result of a selection
made in the SETUP menu).
Example: AC is present, but Time Connect has been selected from the 01 ACIn Control
menu and the current time of day is 6PM. The SETUP menu’s 02C AC In - Time current
setting is 2AM-8AM. The current time of 6PM is outside the connect time, so the inverter/
charger will not connect to the incoming AC until after 2AM. The primary status will
display “Inverting” and the secondary status will display “Time Connect” to let you know
the reason that incoming AC has not connected.
• Auto Connect – Automatically connects to incoming AC power when the incoming AC is
qualified by the inverter/charger (voltage is below the high AC input requirements, above the
SETUP: 03B VAC Dropout setting, and between 50 Hz to 70 Hz for domestic models—40 to
60 Hz for export models).
Info: The Auto Connect setting must be selected if the incoming AC source is a
generator. There is no benefit from using the AC In Control feature if the AC source
is from a generator—the generator power may not be available if an AC In feature is
activated. Also, when the generator is turned on (autostarted or manually), it may be
prevented from connecting because the criteria to allow the AC input to connect (AC In
is based on time, VDC, or SOC) may not have been met.
Note: This is true unless you are using an inverter that has two independent AC inputs—
one for grid and the other for generator (i.e., MSH4024RE)—because the AC In Control
features only work with the GRID IN (AC1) input.
• VDC Connect – Only allows the incoming AC to connect when the DC battery voltage falls be-
low the Connect volts setting in the SETUP menu’s 02D AC In - VDC menu item. Disconnects
from incoming AC when the DC battery voltage rises above the Disconnect volts setting, also
from the 02D AC In - VDC menu. See SETUP menu 02D for more information on the Connect/
Disconnect Volts menu settings.
• Time Connect – Incoming AC only connects when the time of day is between the Connect
and Disconnect time settings in the SETUP menu’s 02C AC In - Time menu item. See SETUP
menu 02C for more information on the Set Connect/Disconnect time menu settings.
• SOC Connect – Incoming AC only connects when the battery bank State of Charge (SOC)
falls below the Connect SOC setting in the SETUP menu’s 02E AC In - SOC menu item. Discon-
nects from incoming AC when the battery bank SOC rises above the Disconnect SOC setting,
also from the 02E AC In - SOC menu. This feature requires the optional ME-BMK (battery
monitor) to be installed. See SETUP menu 02E for more information on the Set Connect SOC
menu settings.
• ACIn - Disabled – Disconnects incoming AC when selected. This setting will prevent incom-
ing AC from connecting to the inverter/charger.
