CAUTION
For the user's own safety, this variable speed drive must be connected to an approved earth terminal).
If accidentally starting the installation is likely to cause a risk to personnel or the machines being driven, it is essential to comply
with the power connection diagrams recommended in this manual.
The variable speed drive is fitted with safety devices which, in the event of a problem, control stopping and thus stop the motor. The
motor itself can become jammed for mechanical reasons. Voltage fluctuations, and in particular power cuts, may also cause the
motor to stop. The removal of the causes of the shutdown can lead to restarting, which may be dangerous for certain machines or
installations.
In such cases, it is essential that the user takes appropriate precautions against the motor restarting after an unscheduled stop.
The variable speed drive is designed to be able to supply a motor and the driven machine above its rated speed.
If the motor or the machine are not mechanically designed to withstand such speeds, the user may be exposed to serious danger
resulting from their mechanical deterioration.
Before programming a high speed, it is important that the user checks that the installation can withstand it.
The variable speed drive 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
standards, and to provide any devices required to ensure the safety of equipment and personnel.
LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.
