Introduction

The ME-ISW (Ignition Switch Lockout) pigtail adapter is designed to automati-

cally DISABLE the inverter function when a 12 volt DC signal is supplied. This

is useful in applications where it may be desirable to prevent 120VAC inverter

loads from being powered while the vehicle ignition switch is turned on.
The ME-ISW 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-ISW; ensure the following requirements:

1. The ME-ISW wire should be connected to a circuit downstream from the

vehicle ignition switch, so that 12VDC is available when the ignition switch

is on, and not available when the ignition switch is off. The circuit selected

should be protected by a fuse rated at 5 Amps DC maximum.

2. The

ME-ISW pigtail MUST be plugged into the Stack port on the inverter

as shown in fi gure 1.

Operation Steps

1. The inverter automatically shuts off and the inverter on/off button on the

inverter (and remote control, if connected) is disabled when the ignition

switch is turned on (provides 12VDC to the ME-ISW pigtail wire).
2. The inverter on/off button (on inverter and remote panel) can be used to

turn the inverter on/off when the ignition switch is turned off (removes 12VDC

from the ME-ISW pigtail wire).

Info: The charger will continue to function and is not affected by

the ME-ISW pigtail operation.
