Introduction
The ME-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 ME-DCLD is installed.
The ME-DCLD pigtail adapter is simple to install and is used with inverters that
provide a Stack port, such as the ME, MS, MS-AE and RD Series inverters.
Installation
Refer to fi gure 2 to install the ME-DCLD; ensure the following requirements:
1.
Connect the ME-DCLD wire to a circuit so that 12VDC is available when the
battery disconnect switch is on, and not present when the battery disconnect
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 ME-DCLD
to ensure this increased voltage does not damage the inverter.
2. The ME-DCLD pigtail MUST be plugged into the Stack port on the inverter
as shown in fi gure 1.
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 the Battery Disconnect Switch is on.
2. The inverter will turn off and the inverter’s ON/OFF button (and on remote
control, if connected) is disabled when the Battery Disconnect Switch is off.
Info: The charger will continue to function and is not affected by
the ME-DCLD pigtail operation.
