Introduction
The MM-DCLD (DC Load Disconnect) pigtail adapter is designed to provide a
means to DISABLE the inverter function when a 12 volt DC signal is removed.
This is useful in applications when a vehicle or boat is placed into storage
and the battery disconnect switch is turned off to disconnect all DC loads, the
inverter can also be automatically turned off if the MM-DCLD is installed.
The MM-DCLD pigtail adapter is simple to install and is used only with the
MM or MMS Series inverters.
Installation
Refer to fi gure 2 to install the MM-DCLD; ensure the following requirements:
1. Connect the MM-DCLD wire to a circuit so that 12VDC is available when
the battery disconnect switch (or ignition switch) is on, and not present when
the battery disconnect (or ignition switch) is off. The circuit selected should
be protected by a fuse rated at 5 Amps DC maximum.
Caution: If using 24 or 48 volts, place a 15k ohm (for 24VDC) or 25k
ohm (for 48VDC) resistor in-line with the red wire on the MM-DCLD
to ensure this increased voltage does not damage the inverter.
2. The MM-DCLD pigtail MUST be plugged into the ACCESSORIES port on the
inverter as shown in fi gure 1. If using the BTS, then a 6-conductor phone
splitter must be used to connect both the MM-DCLD and the BTS.

Operation Steps
1. The inverter’s ON/OFF button (and on remote control, if connected) can be
used to turn the inverter on/off when +12VDC is connected.
2. The inverter will turn off and the inverter’s ON/OFF button (and on remote
control, if connected) is disabled when the +12 VDC is disconnected.
Info: The charger will continue to function and is not affected by
the MM-DCLD pigtail operation.
