4 - Safety Instructions
Permanent magnet synchronous machines must only be serviced by repair shops qualified and
authorised by ABB. For more information concerning service of permanent magnet
synchronous machines, please contact ABB.
WARNING: Only qualified personnel familiar with the relevant safety requirements are
allowed to open and maintain permanent magnet synchronous machines.
WARNING: It is not allowed to remove the rotor of a permanent magnet synchronous machine
without the special tools designed for this purpose.
WARNING: Magnetic stray fields, caused by an open or disassembled permanent magnet
synchronous machine or by a separate rotor of such a machine, may disturb or
damage other electrical or electromagnetic equipment and components, such as
cardiac pacemakers, credit cards and equivalent.
WARNING: Loose metallic parts and waste must be prevented from entering the interior of the
permanent magnet synchronous machine as well as getting into contact with the
rotor.
WARNING: Before closing an opened permanent magnet synchronous machine, all parts
which does not belong to the machine and wastes must be removed from the
interior of the machine.
NOTE: Beware of magnetic stray fields and possible induced voltages when rotating the
separate rotor of a permanent magnet synchronous machine as they may cause damage
to surrounding equipment, for example lathes or balancing machines.
NOTE: These instructions must be followed to ensure safe and proper installation, operation
and maintenance of the motor. They should be brought to the attention of anyone who
installs, operates or maintains this equipment. Ignoring the instruction may invalidate
the warranty.
WARNING: Motors for explosive atmosphere are specially designed to comply with official
regulations concerning the risk of explosion. If improperly used, badly connected,
or altered, no matter how minor, their reliability could be in doubt.
Standards relating to the connection and use of electrical apparatus in explosive
atmosphere must be taken into consideration, especially national standards for
installation. (see standards: EN 60079-14, EN 60079-17, EN 61241-14, EN
61241-17 IEC 60079-14, IEC 60079-17, IEC 61241-14 and IEC 61241-17). All
repairs and overhauls must be carried out according to the standard IEC 60079-
19. Only trained personnel familiar with these standards should handle this type
of apparatus.
