In the case of machines with feet (IM B3 type of construction), the feet are cast or bolted on.
It is possible to change the feet bolted on the housing of the machine, e.g. to change the
position of the terminal box; however, only have this performed by an authorized retrofit
partner.
With the appropriate post working, ensure that the feet mounting surfaces are again on one
plane and parallel to the machine shaft, and shim when required. Professionally touch up
damaged painted surfaces.

3.3 Installation
The machines of this series are three-phase asynchronous machines with a closed primary
(internal) cooling circuit and an open secondary cooling circuit (surface cooling). The surface
cooling varies depending on the version.
Located at the ND end of the stator housing is an air intake cowl that guides the external air
on its way to the motor. The external air is drawn in through openings in the air intake cowl
and flows axially across the outer cooling ribs of the motor frame. The fan wheel for the
external flow of cooling air is attached to the machine shaft.
The fan wheels are bidirectional.
Check the cooling effect below rated speed in the case of frequent switching or braking – or
if the speed is controlled continually below the rated speed.
Machines for use in Zone 21 and Zone 22 have a metal fan.

3.3 Installation
Operating the machine without external fan results in overheating. This may result in
personal injury and material damage.
Never commission the machine without an external fan.
Cooling that does not depend on the speed is achieved by means of a separately driven fan
wheel (forced ventilation). Forced ventilation does not depend on the operating state of the
machine.
The fan wheel for the external flow of cooling air is powered by an independent module and
is enclosed by the fan cover.

Balancing
3.3 Installation
Figure 3-3 IC418
In order to support the machine shaft and maintain its position in the non-moving part of the
machine, only 2 rolling-contact bearings are used. One roller bearing performs the function
of a location bearing that transfers axial and radial forces from the rotating machine shaft to
the non-moving part of the machine. The second roller bearing is implemented as floating
and support bearing in order to allow thermal expansion inside the machine and transfer
radial forces.
The nominal (calculated) useful life of the bearings according to ISO 281 is at least 20,000
hours with utilization of the permissible radial/axial forces. However, the achievable useful
life of the bearings can be significantly longer in the case of lower forces (e.g. operation with
self-aligning couplings).
Avoid rigid couplings.
Roller bearings with permanent lubrication are maintenance-free. For bearings that can be
relubricated, observe the data on the rating plate or lubricant plate.
As standard, the motor is balanced dynamically with a half featherkey (code "H") in
accordance with ISO 8821.
The balance quality corresponds to vibration level "A". Vibration level "B" is optional or
possible on request.

If the environmental requirements are different from the details listed here, then the values
on the rating plate will apply.
Machines intended for use in Zone 1 (type of protection Flameproof Enclosure "d" or
Increased Safety "e") or in Zone 2 (type of protection "n") are designed with IP 55 degree of
protection.
Machines intended for use in Zone 21 have IP 65 degree of protection. Machines intended
for use in Zone 22 have IP 55 degree of protection and can be used in dusty environments
such as grinders, silos, animal feed plants, and malthouses, as well as in certain areas of the
chemical industry.
In addition to the current-dependent overload protective device located in the connecting
leads, we recommend that you use temperature sensors embedded in the stator winding in
order to monitor the temperature and protect the stator winding from overheating.
Machines whose winding is exposed to the danger of condensation due to the climate, e.g.
machines at a standstill in a damp environment or machines which are exposed to large
temperature fluctuations, can be equipped with an anti-condensation heater.
As an option, the machines can be fitted with additional built-on accessories on the
ventilation side (e.g. brake, rotary pulse encoder).
Investigate the influence of sources of heat and cold on the finished installation when it
includes built-on accessories compliant with EN 60079-14!

4.3 Storage
The motor can slide or topple over if it is not correctly lifted or transported. This can result in
death, serious injury, or material damage.
• Use all the lifting eyes on the machine.
• Any eyes that are screwed in must be tightly fastened.
• Eyebolts must be screwed in right up to their supporting surface.
• If necessary, use suitable, sufficiently-sized transport equipment such as lifting straps
(EN1492-1) and lashing straps (EN12195-2).
If any transport locks are in place, remove them before commissioning. Store the transport
locks or disable them. Use the transport locks when transporting the motors again or
reactivate the transport locks.
The machines are packed in different ways depending on how they are transported and their
size. If not otherwise contractually agreed, the packaging corresponds to the packing
guidelines according to ISPM (International Standards for Phytosanitary Measures).

locate machines, equipment and crates on pallets, wooden beams or foundations. Prevent
equipment from sinking into the ground. Do not impede air circulation under the stored items.
Covers or tarpaulins used to protect the equipment against the weather must not come into
contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air
can circulate freely around the equipment.
The storage rooms must provide protection against extreme weather conditions. They must
be dry, free from dust, frost and vibration and well ventilated.
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be
coated with an anti-corrosion agent which will last for a limited amount of time (<6 months).
Apply suitable anti-corrosion measures for longer storage times.
Open any condensation drain holes to drain the condensation depending on the
environmental conditions, every six months at the latest.
Turn the shafts 1x every year to avoid bearing brinelling. Prolonged storage periods reduce
the useful life of the bearing grease (aging).
● For open bearings e.g. 1Z, check the state of the bearing grease over 12 months.
● Replace the grease if it is identified that the grease has lost its lubricating properties or is
polluted. The consistency of the grease will change if condensation is allowed to enter.
● For sealed bearings, replace the DE and NDE bearings after a storage time of 48 months.

Immunity to interference
4.4 Electromagnetic compatibility
If operated with a frequency converter, the emitted interference varies in strength,
depending on the design of the converter (type, interference suppression measures,
manufacturer).
Avoid that the specified limit values stipulated for the drive system (consisting of the
motor and converter) are exceeded.
You must observe the EMC information from the manufacturer of the converter.
The most effective method of shielding is to conductively connect a shielded machine
supply cable to the metal terminal box of the machine (with a metal screw connection)
over a large surface area.
On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages
caused by the converter may occur on the sensor cable.
When used in accordance with their intended purpose and operated on an electrical supply
system with characteristics according to EN 50160, the enclosed machines comply with the
requirements of the EC Directive concerning electromagnetic compatibility.
The machines in principle fulfill the requirements of interference immunity in conformity with
EN / IEC 61000-6-2 . If machines with integrated sensors (e.g. PTC thermistors) are used,
the operating company must ensure sufficient interference immunity by selecting a suitable
sensor signal lead (possibly with shielding, connected in the same way as the machine
feeder cable) and a suitable evaluation unit.
When operating the machines from a converter at speeds higher than the rated speed, then
the mechanical speed limits must be carefully observed (safe operating speed
EN / IEC 60034-1).
