CAUTION
For the user's safety, the variable speed drive to which the module covered by these instructions
is fitted, 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, order it to
stop and, at the same time, stop the motor. The motor itself can become jammed for mechanical
reasons. Finally, voltage fluctuations, and in particular power cuts, may also cause the unit 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 on which the module, covered by this manual, is fitted 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.
Using the drive for hoisting: when using this application, it is essential to follow the special
instructions in an application-specific manual which is available on request. It is the responsibility
of the user to obtain this manual from his usual LEROY-SOMER contact.
LEROY-SOMER declines all responsibility in the event of the above recommendations
not being observed.
