CAUTION
For the user’s safety, the Powerdrive MD Smart variable speed drive made by the integrator must be connected to a
statutory ground (terminal ).
If an inadvertent start to the installation presents a risk to the persons or the machines being driven, it is essential to
comply with the power connection diagrams recommended in this manual.
The Powerdrive MD Smart 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, 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 particular those which must comply with Appendix 1 of
Decree 92.767 of 29 July 1992 on safety.
In such cases, it is essential that the user takes appropriate precautions against the motor restarting after an unscheduled
stop.
The Powerdrive MD Smart 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 Powerdrive MD Smart variable speed drive, made from the components described in this manual, is designed to be
integrated in an installation or an electrical machine, and can under no circumstances be considered 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.
In the event of non-compliance with the above provisions, Leroy-Somer disclaims any and all liability.
This manual describes all the steps required for a system integrator to integrate Powerdrive MD Smart variable speed
drive components into an enclosure, as well as its connection and installation. For commissioning and configuring the
drive, refer to commissioning guide ref. 5641.
This guide addresses versions of variable speed drives greater than or equal to V5.80
