This speed controller must be installed and implemented in compliance with the international
and national standards in force in the premises where it is to be used. It is the responsibility of
the integrator to comply with the EMC directive, among others, which concerns the European
Community.
Compliance with the essential requirements specified in the EMC directive is dependent on
conditioned application of the recommendations provided in the following documents :
– Our catalogue which indicates the accessories to be associated with Speed Controllers, for
instance when radio disturbance filtering is needed.
– Standard IEC 1000-5-2, the recommendations of which are repeated in our EMC
didactic Manual which describes the installation safety measures to comply.
For any information about these documents, please contact our SCHNEIDER commercial agency.

When the speed controller is powered up, the power components and a number of other control
S
components are connected to the mains supply. It is extremely dangerous to touch them.
ATTENTION
H
After switching the ALTIVAR off, wait for 1 minute before touching the equipment. This is the time
required for the capacitors to discharge.
The motor can be stopped during operation, by inhibiting the start command or the speed
reference, while the speed controller remains switched on. If safety of personnel requires
prevention of any sudden restarts, this electronic locking will not be sufficient : provision must
be made for the power circuit to be broken.
The speed controller incorporates safety devices which can shut down the speed controller and
thus the motor in the event of faults. The motor itself may be blocked due to mechanical faults.
In addition, voltage variation and mains failures in particular may result in stoppages.
NOTE
The clearance of the causes of a stoppage may cause the motor to restart, entailing danger for
certain machines or installations, especially those which conform to safety regulations.
In such cases, therefore, the user must take precautions to avoid restarting, in particular by the
use of a speed detector, to disconnect the supply to the speed controller in the event of a non-
programmed stop of the motor.
The equipment has been designed to conform to IEC standards.
In general, power to the speed controller must be switched off before any electrical or
mechanical intervention on the installation or the machine .
The products and materials presented in this document may be changed or modified at any time,
either from a technical point of view or in the way they are operated. Their description can in no
