CAUTION
For the user’s own safety, the 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.
It is important that the user checks that the installation can withstand it before programming a high speed.
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.
