1. Introduction

The Legrand 422684 control unit implements state-of-the-art functions reuired for control and managmrnt multisource.

The system incorporates a uniue series of hardware and software features which guarantee high flexibility, e.g. 

management of three supply source lines and two tie breakers, graphic display, double power supply, expansion modules, 

programmable system layout, integrated PLC etc., for use in a wide variety of possible conditions of application, all of 

which can be programmed by the user. 

The graphic display shows and allows to control the system situation effectively. The expansion slots allows to increase 

the hardware resources also allowing adaptability to future needs.
