Air cooling:

and the technical documentation that accompanies the product.
Cooling method IC 410 – Self-cooling
without
a fan.
Cooling method IC 416 – Surface cooling
with
a fan.
The following must be observed:
•
The installation conditions must not impair thermal convection and radiation.
•
The cooling air used for forced ventilation must be able to flow in freely and the hot air must be
able to flow out freely. The hot exhaust air must not be sucked back in.
•
A clearance of at least 100 mm must be observed in relation to neighboring machine parts.
•
If installed in very dirty locations, the housing surface and airways must be cleaned regularly.
flange connection:
By connecting the motor to the mounting surface, a part of the motor loss performance is lead
away via the flange.
The dimensions of the mounting surface based on their axis height are listed in the following table
1. This information provides minimum values for the safe heat dissipation via the motor flange
surfaces.

Table 1: Mounting surfaces
The heat dissipation conditions approve on larger mounting surfaces. An insulated mounting of the
motors is not permitted.

Balancing, output elements, vibration
Do not subject the shaft or bearings to impacts.
On mounting and dismounting output elements, it is not permitted for any axial forces
to be applied to the motor.
The generally applicable measures for the protection of output elements against
physical contact are to be followed.
If a motor without output elements is commissioned, measures must be put in place to
ensure the key is not flung out.
Balancing
On an ideal design with fitted key, the runners are dynamically balanced with half fitted keys.
(acc. to EN 60034-14 / ISO 8821 / ISO 1940)
NOTE:
Observe the type of balancing as identified on the shaft end face and on the
nameplate:
H = Balancing with half key
(standard design)
F = Balancing with full key
(special design)
N = Balancing without key
(special design)
