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.

If the motor is attached to a gear unit, the EX labelling of the gear unit must also be observed!
Explosive gas mixtures or dust concentrations may cause severe or fatal injuries in combination with
hot, electrically live and moving components of electrical machines.
