WARNING
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.
This equipment is fitted with safety devices which, in the event of a problem, control stopping and thus stop the motor or motors.
The motors themselves may also become jammed for mechanical reasons. Voltage fluctuations, and in particular power cuts,
can also cause the motor to stop. The removal of the causes of the shutdown can lead to restarting, which could 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 drive(s) which form part of this equipment is(are) designed to be capable of supplying the motor(s) associated with a machine
driven beyond its rated speed.
If the motor(s) or the machine are not mechanically designed to withstand such speeds, the user could 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.
This equipment 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.
