Please refer to your delivery documentation for the exact weight specifications.
Note on thrust-bearing motors:
The motor must only be transported horizontally and standing on its feet, or else the oil filler plug
with the air hole (see Appendix 3 – Fig. 8 on the bearing end plate, side A, must be replaced with
a solid screw plug (M20x1.5).
The motor shaft and the connection surfaces must be protected against corrosion. The motor must
only be transported with a shaft protection cover; damage to the motor shaft must be avoided.
Intermediate storage:
If a motor is not to be commissioned immediately after delivery, it should be stored inside a building
in am inside room which is dry, dust-free and free of significant vibration (V
rms
≤ 0.2 mm/s).
The electric motors should be stored at as uniform a temperature as possible, not outside of the
temperature range -15 to +60 °C, for no more than two years. Elevated storage temperatures
within the framework of the working temperature accelerate the rate at which seals and bearing
grease deteriorate and therefore have a negative impact on the service life even before the unit
has been commissioned. Direct exposure to incident solar radiation, UV light and ozone also lead
to an ageing of the gaskets and must be avoided!
Please note that the guarantee periods start from the date of delivery. We therefore recommend
that storage periods be kept to a minimum.
Should nevertheless a longer storage be necessary, the environmental conditions acc. to DIN
EN 60721-3-1 (class 1K2/1M1) have to be observed. Contrary to the DIN, an expanded
temperature range of – 15 °C to + 60 °C is permitted.
2.6 Installation conditions, cooling details
For motors with water-cooling please take Section 8 into account in addition.
Surroundings:
The motor can be installed in roofed rooms in dusty or damp environment and under normal
climatic conditions.
Unless alternative arrangements have been made, the motor is designed by default for the
following climatic conditions:
Ambient temperature 0 °C to 40 °C
Installation height ≤ 1000 m above sea level
Relative humidity 5 % to 85 %
All other allowed application conditions have to correspond to DIN EN 60721-3-3 (class 3K3/3Z12).
It is absolutely imperative to comply with these climatic conditions when installing the unit.
Aggressive, corrosive, abrasive and plastic-dissolving solutions should be kept well away from the
motor and the air that is used to cool it.
Consultation with the motor manufacturer is essential in the case of installation outdoors.
