1.4. Safety devices and general safety instructions
For the user's own safety, the dual plate D700 must be connected to approved earth terminals on the plate. The
tools needed to make this connection are not included with the plate.
Note: The 0Vs on the circuit boards of D700 AVRs are connected to earth
It is essential to comply with the power connection diagrams recommended in this manual.
The dual plate D700 contains devices which can, in the event of problems, control generator field weakening or
overexcitation. This generator itself can become jammed for mechanical reasons. Finally, voltage fluctuations or
power cuts may also cause the unit to stop.
The dual plate D700 which is the subject of this manual is designed to be integrated in an installation or an
electrical machine, and can under no circumstances be considered to be a safety device. It is therefore the
responsibility of the machine manufacturer, the designer of the installation or the user to take all necessary
precautions to ensure that the system complies with current applicable standards, especially safety standards,
and to provide any devices required to ensure the safety of equipment and personnel (especially the prevention
of direct or indirect contact when the plate is powered up).
LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.
The various interventions described in this manual are accompanied by recommendations or symbols to alert
the user to potential risks of accidents. It is vital that you understand and take note of the different safety
instructions provided.
This symbol warns of consequences which may arise from inappropriate use of the AVR or equipment, since
electrical risks may lead to material or physical damage as well as constituting a fire hazard.
This symbol alerts users to a safety instruction warning of electrical danger to personnel.
1.4.1. General information
The dual plate D700 may contain unprotected live parts, as well as hot surfaces, during operation.
Unjustified removal of protection devices, incorrect use, faulty installation or inappropriate operation could
represent a serious risk to personnel and equipment.
For further information, consult the documentation.
All work relating to transportation, installation, commissioning and maintenance must be performed by
