DANGER
Explosion hazard
The increased danger in areas with flammable dust requires the strict consideration of the
general safety and commissioning information. Explosive concentrations of dust may cause
explosions if ignited by hot or sparking objects. Such explosions may cause serious or fatal
injuries to persons or severe material damage.
It is essential that the persons responsible are qualified according to the national and local
regulations.

3.3.1 Commissioning information / Application area
If the motors are to be suitable for inverter operation, this must be indicated when placing the order.
The additional operating instructions B1091-1 must be observed. The motors must be protected
against overheating with suitable monitoring devices! The dust deposit must not be thicker than 5 mm.
The motors are designed for voltage and frequency range B of EN 60034, part 1.
Exception: The motors of sizes 132MA/4 2D, 132MA/4 3D, 132LH/4 2D and 132LH/4 3D correspond
to voltage and frequency range A.
Motors for use in Zone 21 and Zone 22 with TF labelling may be thermally monitored – as sole
protection – via the installed PTC in combination with a suitable triggering device.
Electrical equipment for use in areas with flammable dust comply with the DIN EN 60079-0,
IEC 60079-0, EN 60079-31, IEC 60079-31, DIN EN 60034 and IEC 60034 standards.
The standard’s valid version can be found in the EU Declaration of Conformity or in the IECEx CoC.
The degree of explosion hazards determines zone division. The operator/employer is responsible for
zone division (in Europe: RL 1999/92/EC).
If an X has been added to the certificate, special requirements must be observed in the EU type-
examination certificate, the IECEX CoC and/or the documentation to be considered. It is prohibited to
use standard motors that are not certified for explosion hazard areas in explosion hazard areas.
