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 supply the equipment via a circuit-breaking device (power
contactor) which can be controlled via an external safety system (emergency stop, detection
of errors on the installation).
The variable speed drive is fitted with safety devices which, in the event of a fault, 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.
