DANGER!
Explosion hazard
All work must only be carried out with the machine at a standstill and the power to the system
switched off .
Higher temperatures than the maximum permitted surface temperature of the housing may
be present inside the motor. The motor must therefore never be opened in an explosive
atmosphere!
Failure to comply with this may result in the ignition of an explosive atmosphere.

WARNING
Explosion hazard
Excessively heavy dust deposits must be avoided, as these impair the cooling of the device!
Impairment or obstruction of the flow of cooling air, for example due to partial or large area
coverage of the fan cover or the entry of foreign bodies fall into the fan must be avoided in
order to ensure adequate cooling.
Only cable glands and reducers which are approved for use in explosion hazard areas may
be used.
All cable glands which are not used must be closed with blind screw plugs which are approved
for potentially explosive areas.
Only the original seals may be used.
Failure to comply increases the risk of ignition of an explosive atmosphere.

For these motors, the following information specifically or complimentarily apply.
The motors are suitable for use in zone 2 and correspond to device group II, category 3G and may be
used at an ambient temperature from -20 °C to +40 °C.
Type suffix: 3G e.g.: 80 L/4 3G TF
Labelling: II 3G Ex ec IIC T3 Gc With indication of the temperature

NOTICE
Motor attachments
Explosion-protected electric motors are often delivered with attached components and devices, such
as a gear unit or a brake.
• In addition to the labelling of the motor, observe any labelling on the attached components and
devices. Consider any resulting restrictions for the entire drive.
Explosive gas mixtures or dust concentrations may cause severe or fatal injuries in combination with
hot, electrically live and moving components of electrical machines.
The increased danger in explosion hazard areas requires especially strict observance of the general
safety and commissioning information. It is essential that the persons responsible are qualified according
national and local regulations.
Explosion protected electrical machines with ignition protection class Ex n correspond to the standard
series EN 60034 (VDE 0530), as well as IEC 60079-0:2018 and EN IEC 60079-7:2015/A1:2018. The
degree of explosion hazards determines zone division. DIN EN 60079, Part 10 provides information
about this. The operator is responsible for the zone division. The use of motors which are not certified
for explosion hazard areas is prohibited in explosion hazard areas.
