Target group
Any mechanical work may only be performed by adequately qualified personnel. Quali-
fied personnel in the context of this documentation are persons familiar with the design,
mechanical installation, troubleshooting and servicing of the product who possess the
following qualifications:
• Training in mechanical engineering, e.g. as a mechanic or mechatronics technician
(final examinations must have been passed).
• They are familiar with these operating instructions.
Any electronic work may only be performed by adequately qualified electricians. Quali-
fied electricians in the context of this documentation are persons familiar with electrical
installation, startup, troubleshooting and servicing of the product who possess the
following qualifications:
• Training in electrical engineering, e.g. as an electrician, electronics or mechatronics
technician (final examinations must have been passed).
• They are familiar with these operating instructions.
All work in further areas of transportation, storage, operation and waste disposal must
only be carried out by persons who are trained appropriately.
All qualified personnel must wear appropriate protective clothing.
2.4
Designated use
The explosion-proof electric motors are intended for industrial systems.
When installed in machines, startup of the motors (i.e. start of designated operation) is
prohibited until it is determined that the machine meets the requirements stipulated in
EC Directive 94/9/EC (ATEX Directive).
Air-cooled types are dimensioned for ambient temperatures of -20 °C to +40 °C and in-
stallation altitudes
≤
1000 m above sea level. Note that information on the nameplate
may differ. The ambient conditions must comply with all the specifications on the name-
plate.
NOTES ON EXPLOSION PROTECTION
• The motor is only allowed to be operated under the conditions described in the
"Startup" section.
• A motor may only be operated with the frequency inverter when the requirements
of the prototype test certificates and/or this documentation and the information on
the nameplate of the motor, if available, are fulfilled.
• There may be no aggressive substances in the vicinity that could damage the paint
and seals.
• The motors must not be operated in areas/applications that cause strong electrical
charge on the motor housing, e.g. as a fan motor in a dust-transporting tube as this
may cause electrostatic charge of the coated surfaces.
