2. Warnings and legal information

Legal information and responsibility

THOMSON TECHNOLOGY takes no responsibility for installation or operation of the
generator set. If there is any doubt about how to install or operate the generator set
controlled by the unit, the company responsible for the installation or the operation of the set
must be contacted.

The units are not to be opened by unauthorised personnel. If opened anyway, the warranty will
be lost.

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 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.

Definitions

Throughout this document a number of notes and warnings will be presented. To ensure that
these are noticed, they will be highlighted in order to separate them from the general text.

Notes

Warning

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.
