2.5 Installation conditions, cooling specifications
Environment:
The motor can be installed indoor within dusty and humid environments correspondent to its protection
class (see rating plate).
As long as special agreements weren’t agreed upon, the drive is designed to the following standard-
ized climatical application conditions:
•
Environmental temperature 0 °C to 40 °C
•
Installation altitude
≤
1000 m above sea level
Relative humidity is 5% to 85%. For the other permissible application conditions refer to
DIN EN 60721-3-3 (class 3K3/3Z12).
These climatical conditions must be unconditionally observed at installation.
Generally, it is necessary to keep aggressive, corrosive, abrasive as well as plastic-dissolvent media
from the motor and its cooling air.
Contact the motor manufacturer if an outdoor installation must be carried out.
Cooling specifications:
Environmental conditions see chapter 2.4 and technical product data.
Cooling process IC 410 – Natural cooling without fan.
Basically, the following must be observed:
•
The heat convection and the thermal radiation must not be affected by the installation conditions.
•
In the case of forced air cooling, the cooling air must be able to freely enter and the hot air must
freely exit. Do not draw in the heated exit air anymore.
•
The distance to adjacent machine parts should not fall below 100 mm.
•
The housing surface and the air in-/outlets must be cleaned regularly, if dirt accumulation is ex-
tremely.
Mounting specifications:
By coupling the motor to the installation surface a part of the motor dissipation is diverted via the
flange.
The following chart 1 demonstrates the measurings of the installation surfaces dependent of the shaft
height. These specifications are lower limiting values regarding safe heat dissipation via the flange
surfaces of the motor.

Chart 1: Installation surface
The heat dissipation conditions improve where the installation surfaces are larger.
An isolated installation of the motors is not permitted!
