1. About this document
General purpose
This document is the Quick Start Guide for the Multi-line 2 product MDR-2. The general purpose
of the document is to help the user with the first steps of installing and using the unit.
Intended users
This Quick Start Guide is mainly intended for the panel builder in charge. On the basis of this
document, the panel builder designer will give the electrician the information he needs in order
to get started to install the unit. For detailed electrical drawings, the Designer’s Reference
Handbook must be used.
Contents/overall structure
This document is divided into chapters, and in order to make the structure simple and easy to
use, each chapter will begin from the top of a new page.
Please make sure that you also read the Designer’s Reference Handbook
before starting to work with the Multi-line 2 controller and the gen-set to be
controlled. Failure to do this could result in human injury or damage to the
equipment.

2. Warnings and legal information
This chapter includes important information about general legal issues relevant in the handling
of DEIF products. Furthermore, some overall safety precautions will be introduced and
recommended. Finally, the highlighted notes and warnings, which will be used throughout this
document, are presented.
Legal information and responsibility
DEIF takes no responsibility for installation or operation of the generator set. If there is any
doubt about how to install or operate the generator controlled by the unit, the company
responsible for the installation or the operation of the set must be contacted.
Electrostatic discharge awareness
Sufficient care must be taken to protect the terminals against static discharges during the
installation. Once the unit is installed and connected, these precautions are no longer
necessary.
Safety issues
Installing the unit implies work with dangerous currents and voltages. Therefore, the installation
of the unit should only be carried out by authorised personnel who understand the risks involved
in the working with live electrical equipment.
Definitions
Throughout this document a number of notes with helpful user information will be presented. To
ensure that these are noticed, they will be highlighted in order to separate them from the
general text.
Note symbol
Warnings
Be aware of the hazardous live currents and voltages. Do not touch any AC
measurement inputs as this could lead to injury or death.
The notes provide general information which will be helpful for the reader to
bear in mind.
The warnings indicate a potentially dangerous situation which could result in
death, personal injury or damaged equipment if certain guidelines are not
followed.
The units are not to be opened by unauthorised personnel. If opened anyway, the
warranty will be lost.
