 Enable
the free flow of air to all sides of the gear unit.
 Ensure
adequate space around the gear unit.
 With geared motors, the cooling air of the motor fan must be able to flow unobstructed
onto the gear unit.
 Do not enclose or encase the gear unit/geared motor.
 Do not subject the gear unit to highly energetic radiation.
 Do not direct warm exhaust air from other units onto the gear unit/geared motor.
 The base or flange to which the gear unit is attached must not input any heat into the
gear unit during operation.
 Do not pile up dust in the area of the gear unit

Danger!
 The cooling air supplied to the gear unit/geared motor must be within the permissible
temperature range stated on the rating plate.
 In case of direct sunlight falling onto the gear unit, the cooling air supplied to the gear
unit/geared motor must be at least 10°C below the highest permissible temperature of
the ambient temperature range Tu, which is stated on the rating plate.
Danger!
Drive and driven elements, e.g. coupling and chain-wheel hubs must be mounted onto
the drive and driven shaft of the gear unit using suitable pullers that will not apply
damaging axial forces onto the gear unit. In particular, do not hit the hubs with a
hammer.
Note!
Use the end thread of the shafts for pulling. Fitting can be aided by coating the hub
with lubricant or heating it up to approx. 100
o
C beforehand.
