1. General information
1.1 Warnings, legal information and safety
1.1.1 Warnings and notes
Throughout this document, a number of warnings and notes with helpful user information will be presented.
To ensure that these are noticed, they will be highlighted as follows in order to separate them from the general text.
Warnings
Warnings indicate a potentially dangerous situation, which could result in death, personal injury or damaged equipment, if certain guidelines are not followed.
Notes
Notes provide general information, which will be helpful for the reader to bear in mind.
1.1.2 Legal information and disclaimer
DEIF takes no responsibility for installation or operation of the generator set. If there is any doubt about how
to install or operate the engine/generator controlled by the Multi-line 2 unit, the company responsible for the
installation or the operation of the set must be contacted.
The Multi-line 2 unit is not to be opened by unauthorised personnel. If opened anyway, the warranty will be lost.
Disclaimer
DEIF A/S reserves the right to change any of the contents of this document without prior notice.
The English version of this document always contains the most recent and up-to-date information about the
product. DEIF does not take responsibility for the accuracy of translations, and translations might not be updated at the same time as the English document. If there is a discrepancy, the English version prevails.
1.1.3 Safety issues
Installing and operating the Multi-line 2 unit may imply work with dangerous currents and voltages. Therefore,
the installation should only be carried out by authorised personnel who understand the risks involved in working with live electrical equipment.
Be aware of the hazardous live currents and voltages. Do not touch any AC measurement inputs as this could lead to injury or death.
1.1.4 Electrostatic discharge awareness
Sufficient care must be taken to protect the terminal against static discharges during the installation. Once the
unit is installed and connected, these precautions are no longer necessary.

DEIF A/S Page 4 of 47
1.1.5 Factory settings
The Multi-line 2 unit is delivered from factory with certain factory settings. These are based on average values
and are not necessarily the correct settings for matching the engine/generator set in question. Precautions
must be taken to check the settings before running the engine/generator set.
1.2 About the installation instructions
1.2.1 General purpose
These Installation Instructions mainly include general product and hardware information, mounting instructions, terminal strip descriptions, I/O lists and wiring descriptions.
The general purpose of this document is to give the user important information to be used in the installation of
the unit.
Make sure to read this document before starting to work with the Multi-line 2 unit and the genset to be controlled. Failure to do this could result in human injury or damage to the equipment.
1.2.2 Intended users
These Installation Instructions are mainly intended for the person responsible for the design and installation.
In most cases, this would be a panel builder designer. Naturally, other users might also find useful information
in the document.
1.2.3 Contents and 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.

2. General product information
2.1 ASC product information
Introduction
The Automatic Sustainable Controller, ASC, is part of the DEIF Multi-line 2 product family. Multi-line 2 is a
complete range of multi-function inverter and generator protection and control products, which integrate all
the functions you need into one compact and attractive solution.
The concept of the ASC is to offer a cost-effective solution to EPCs and other parties in the solar energy field,
who need a flexible generator protection and control unit for medium to large PV applications. As the ASC is
part of the Multi-line product family, the standard functions can be supplemented with a variety of optional
functions.
Type of product
The Automatic Sustainable Controller, ASC, is a micro-processor-based control unit containing all necessary
functions for protection and control of an inverter.
It contains all necessary 3-phase measuring circuits, and all values and alarms are presented on the LCD
display, and the ASC offers TCP/IP communication for communication to various parties, for example SCADA
or HMI.
Options
The Multi-line 2 product range consists of different basic versions, which can be supplemented with the flexible options needed to provide the optimum solution. The options cover for example various protections for
inverter/generator, busbar and mains, voltage/var/PF control, various outputs, power management, serial
communication, additional operator display and so on.
2.2 Standard functions

2.4 Off-grid applications, power management
2.4.1 Off-grid applications, power management
This application is using the CAN bus power management link between the DEIF controllers in the system.
Thereby it is not necessary to install additional hardwiring between the ASC and the gensets.

2.5 Off-grid, stand-alone mode
This application is used if the gensets already have a control system on top of them (referred to as “Controller” in the picture).
The ASC needs inputs from the GB positions (closed) and the produced active and reactive power, represented by analogue 4 to 20 mA signals.

2.7 Grid-tied, stand-alone
2.7.1 Grid-tied, stand-alone
This application is used if no AGC mains is installed to facilitate the power management parallel to mains
functions. The ASC needs inputs from the MB positions (open/closed) and the produced active/reactive power from the mains incomer or outgoing. This is represented by analogue 4 to 20 mA signals.

2.8 Combination (off-grid + grid-tied), power management
2.8.1 Combination (off-grid + grid-tied), power management
This application is used when the application has to be available in grid-tied modes as well as off-grid (islanded modes). In this example, the CAN bus link is wired between the AGC mains, AGC gensets and the ASC.
It is not necessary to introduce other additional measurements or hardwiring since all necessary data is available on the CAN bus for power management.

2.9.1 Combination (off-grid + grid-tied), stand-alone
This application is used when the application has to be available in grid-tied modes as well as off-grid (islanded modes). In this example, third party controllers are installed (referred to as “Controller” in the picture) and
therefore it is necessary to hardwire signals from the breaker positions (GBs and MB) and measure the mains
power and reactive power, the summated genset power and the summated genset re-active power.

5.1 AC connections
The Multi-line 2 unit can be wired up in 1-phase, 2-phase or 3-phase configuration.
Contact the switchboard manufacturer for accurate information about required wiring for the
specific application.
5.1.1 Neutral line (N)
When 3-phase distribution systems are used, the neutral line (N) is only necessary if it is a 3-phase + neutral
system. If the distribution system is a 3-phase system without neutral, then leave the terminals 84 and 88
empty.
5.1.2 Current transformer grounding
The current transformer ground connection can be made on s1 or s2 connection, whichever is preferred.
5.1.3 Fuses
If the cables are protected with fuses, then use 2 A, slow blow.
5.1.4 Breaker wiring
The breaker off wiring is an example only.
