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 gener-
al text.
Warnings
Warnings indicate a potentially dangerous situation, which could result in death, personal in-
jury 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 war-
ranty will be lost.
Disclaimer
DEIF A/S reserves the right to change any of the contents of this document without prior notice.
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 work-
ing with live electrical equipment.
Be aware of the hazardous live currents and voltages. Do not touch any AC measurement in-
puts 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.
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.
