Installation
2.0 Installation
Before installing the remote, read the entire installation section to determine
how you are going to install your ME-MR. A thoroughly planned system is
much more likely to meet your inverter system needs.
Info: Installations should be performed by qualified personnel, such
as a licensed or certified electrician. It is the installer’s responsibility
to determine which safety codes apply and to ensure that all appli-
cable installation requirements are followed. Applicable installation
codes vary depending on the specific location and application.
Info: Review the “Important Product Safety Information” on the
front inside cover page before any installation.
• Before connecting any wires, determine the remote 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 an boat, RV or truck; ensure the conductors
passing through walls, bulkheads or other structural members are protected
to minimize insulation damage such as chafing, which can be caused by vi-
bration or constant rubbing.
Installing the remote control is a simple process and requires the following
tools:
• Phillips screwdriver • Level • Drill Motor
• Cut-out tool (knife/saw) • Pencil • Drill Bit (7/64”)
2.1 Installation Procedure
Select an appropriate location to install the remote control. Allow ample
room to access the remote’s buttons and to view the LEDs. Ensure the
viewing angle of the display is appropriate.
Refer to figure 2-1 for flush mount hole cutout dimensions.
Refer to figure 2-2 for Surface Mount Bezel dimensions.
Run the remote cable between the remote and the inverter/charger. This
cable is a 4-wire telephony standard with RJ11 connectors on each end.
A standard telephone cable may be substituted if the provided remote
cable is not able to be used.
Connect the remote cable into the RJ11 “Remote” port (has blue label)
on the inverter/charger (see figure 2-3).
Have the inverter connected to batteries, but ensure the inverter is off
and that no AC power is connected to the inverter.
While monitoring the front of the remote, connect the other end of the
cable into the RJ11 jack on the back-side of the remote (see figure 2-
3).

Setup
3.0 Setup
When the remote is connected to a Magnum inverter/charger, the settings in
the remote control determine the inverter/charger operating parameters. The
default settings in the remote control (see Table 3-4, Inverter/Charger Default
Settings) are adequate for most installations, however you have the option to
change some of the operating parameters if required. This section will show
you how to navigate the remote, give you an understanding of the function of
each adjustable setting and help you decide what setting should be used.
3.1 Navigating the Remote’s Menu
The ME-MR has an internal structure that provides menu items and adjust-
able settings that provide the ability to configure your inverter/charger to
your specific parameters.
Info: See figure 4-1, Inverter/Charger Menu Map for a complete map
of the inverter/charger menu items and adjustable settings.
Familiarize yourself with the items on the front panel which are used to find,
adjust and save the desired setting. They are:
• LCD Display - The bottom line of the LCD display shows the menu items,
adjustable settings or the meters display information.
Info: The bottom line of the LCD display returns to the Home
Screen to show DC voltage and current (see Figure 3-1) after 30
Seconds - if no buttons have been pressed.
Info: When the ”←” (left facing arrow) symbol is shown on the dis-
play, it indicates that the displayed setting has been selected and
will be used.
• Menu Pushbutton - Allows simple access to the menu items that can
help with configuring, monitoring and troubleshooting your inverter/charger
system.
• Change Pushbutton - This button allows you to quickly scroll through
and select various menu items and settings after pressing the menu pushbut-
ton.
• Save Pushbutton - This button saves the menu item displayed on the
screen. A saved setting is indicated by arrow symbol.

Setup
3.2 Menu Pushbuttons and Menu Items
Read this section to help understand the function of each menu pushbutton
and the configurable settings - to determine if they should be changed to
optimize the operation of the inverter/charger.
This menu pushbutton gives a quick means of changing your Shore setting to
coordinate with the circuit breaker rating from the incoming AC source.
SETUP: 01 SHORE - This selection ensures the inverter AC loads
receive the maximum current available from the utility or generator power.
Whenever the utility or generator is connected to the inverter (thru AC HOT
1), the current used to power the AC loads and to charge the batteries is
monitored. When the total current used to power the AC loads and charge
the batteries begins to approach the Shore setting, the current that was
used for charging the batteries will automatically be reduced. This ensures
the AC loads have all the available current when needed. The feature is not
available on the MM and MMS inverter/chargers.
Default setting: Shore Max = 30A
Where to set: Set the Shore setting to match the current rating of the utility
power or generator’s circuit breaker. If using multiple AC sources (utility and
generator) through an AC transfer switch, adjust this setting to the smaller
AC breaker size. This setting is very dependent on the stability of the AC
source. If using a generator, factors such as altitude and output voltage
regulation may require a lower setting than the generator’s breaker size. If
the input breaker to the charger is tripping, because it is a weak breaker, try
reducing this setting to next lower level.
CAUTION: The Shore Max setting does not limit the current to the
inverter loads. If the current from the loads on the output of the
inverter are greater than the circuit breaker rating on the incoming
AC source, you may experience nuisance tripping of this breaker.

Setup
SETUP: 02 SEARCH - Allows you to turn off the Search Watts
feature or adjust the power level to determine when the search watts fea-
ture becomes active. The power level range selection is 0W(off) to 20W. If
this feature is not needed, select Search=Off. When search is turned off, the
inverter continuously provides full AC voltage to the loads.
Default setting: Search= 5W.
Info: When the Search Watts feature is active, “Search” appears on
the top line of the LCD display and the green ‘INV’ LED
will slowly flash.
What is the Search watts feature? This feature is used to help save
battery power by reducing the inverter’s output to search pulses when there
is no detectable load. If someone turns on a load greater than the wattage
level setting while the inverter is searching, the inverter will start inverting
to provide full voltage on its output.
Should I use the Search watts feature? If the inverter can spend a great
deal of time searching (to reduce the power drain on your batteries) and you
can tolerate small loads (less than 5 watts) from being on, then the search
mode feature should be used. However, if you require some small load (i.e.
digital clocks, satellite receivers, answering machines, etc.) to always be on,
then this feature should be turned off (Search = Off).
I want to use the Search watts feature, how do I determine where
to set it? The search watts setting should be adjusted to the same power
level (or the next lower setting) of the smallest load that you want to run. If
you don’t know the wattage of the smallest load you want to run, turn the
load on and decrease the Search watts setting until the load comes on and
stays on.
Example: You have reviewed all the loads you want to run and determined
that the smallest load is a 20 watt light, then set the Search = 20W. Whenever
you turn on any load (because all the loads are greater than 20 watts), the
inverter will stop searching and start inverting to deliver power to the load.
Info: Even though the search feature is on, some connected
equipment may draw enough current even while off keep the
inverter in the “invert”.
