1 - RECEPTION
This manual or its condensed version is to be given to the end user. In the event of this notice not being translated into the language of the country in which
the motor is used, the distributor is responsible for its translation and for distributing it to end users.
Products to which this manual applies may not be commissioned before the machinery in which they are installed has been declared to conform to the Directives that apply to it.
This equipment and its accessories or associated equipment must be installed by a professional, who is liable for ensuring compliance with all installation rules, decrees,
orders, laws, directives, application memos, standards (where explosive atmospheres are involved, standard IEC-EN 60079-14 as a minimum), regulations, good trade
practices and any other documents relating to the installation site. The professional is also liable for ensuring compliance with the values indicated on the motor information
plate(s), instruction manuals, installation and maintenance manuals and any other document provided by the manufacturer.
Constructions Electriques de Beaucourt (CEB) and LEROY-SOMER cannot be held liable for non-compliance with all or part of the above or with any part of
this manual.
On receipt of your motor, check that it has not suffered any damage in transit.
If there are obvious signs of damage, contact the carrier (you may able to claim on their insurance) and after a visual check, turn the motor by hand to detect
any malfunction.
1.1 - Identification and marking
Check that the information shown on the nameplate is compatible with the explosive atmosphere that is present, the utilisation zone and the ambient and surface
temperatures.
