The copyright to these operating instructions is held by Siemens AG.
These operating instructions must not be wholly or partly reproduced for competitive
purposes, used in any unauthorized way or made available to third parties without
agreement of Siemens AG.
1.3
Intended use
The motors described in these operating instructions have been designed for stationary use
in general engineering applications.
They comply with the harmonized standards of the series EN 60034 (VDE 0530). They are
not approved for operation in hazardous zones and areas.
Unless otherwise agreed, the motors have been designed for use in plants and equipment in
industrial environments.
The motors have been built using state-of-the-art technology and are shipped in an
operationally reliable condition. Changes made by users could affect this operational
reliability and are forbidden.
Note
The performance data assumes an ambient temperature of
-15 °C to +40 °C and an
installation altitude of up to 1
000 m above sea level.
In the case of other ambient temperatures and installation altitudes, please contact Technical
Support.
The motors are designed only for the area of application described in Section Technical data
(Page 65).
Do not operate the gearboxes outside the specified performance limits.
Any different operating conditions require new contractual agreements.
Equipment with degree of protection ≤ IP54 must never be used outdoors. Air-cooled
versions are designed for ambient temperatures of -15 °C to +40 °C and for an installation
altitude of up to 1 000 m above sea level. Please note any deviations to the data on the
rating plate. Conditions at the location of use must comply with all specifications on the rating
plate.
Do not climb on the motor. Do not place any objects on the motor.

1.4 Obligations of the user
BA 2320
10 Operating Instructions, 02/2015, 70000004023775
1.4
Obligations of the user
The operator must ensure that all persons assigned to work on the gearbox have read and
understood these operating instructions and that they follow them in all points in order to:
●Eliminate the risk to life and limb of users and other persons.
●Ensure the operational safety of the gearbox.
●Avoid disruptions and environmental damage through incorrect use.
Note the following safety information:
Shut down the geared motors and disconnect the power before you carry out any work on
them.
Make sure that the drive unit cannot be turned on accidentally, e.g. lock the key-operated
switch. Place a warning notice at the drive connection point which clearly indicates that work
is in progress on the geared motor.
Carry out all work with great care and with due regard to "safety".
For all work, observe the relevant regulations for work safety and environment protection.
Read the instructions on the rating plates attached to the geared motor. The rating plates
must be kept free from paint and dirt at all times. Replace any missing rating plates.
In the event of changes during operation, switch off the drive unit immediately.
Take appropriate protective measures to prevent accidental contact with rotating drive parts,
such as couplings, gear wheels or belt drives.
Take appropriate measures to prevent accidental contact with parts and equipment that heat
up to over +70 °C during operation.
When removing protective equipment, keep fasteners in a safe place. Re-attach removed
protective equipment before commissioning.
Collect and dispose of used oil in accordance with regulations. Remove oil spillages
immediately with an oil-binding agent in compliance with environmental requirements.
Do not carry out any welding work on the gearbox. Do not use the gearbox as a grounding
point for welding operations.
Carry out equipotential bonding in accordance with applicable regulations and directives by
electrotechnology specialists.
Do not use high-pressure cleaning equipment or sharp-edged tools to clean the gearbox.
Observe the permissible tightening torque of the fastening bolts.
Replace damaged bolts with new bolts of the same type and strength class.
Siemens AG accepts the warranty only for original spare parts.
The manufacturer who installs the geared motors in a plant must include the regulations
contained in the operating instructions in its own operating instructions.

The motor is equipped with grease-lubricated roller bearings. The bearings are permanently
lubricated.
The stator winding is designed for temperature class 155(F).
In the standard version, the rotor corresponds to vibration severity level A.
The technical data for the optional monitoring equipment can be viewed in the circuit
diagrams, on the rating plate or in the special order documents.
Housing
The stator housing and the rating plate are made from aluminum casting up to size 160, and
from cast iron from size 180.
The surface of the stator housing has cooling fins and a mounted terminal box.
The fan cover is made of sheet steel.

2.2
Cooling
NOTICE
High housing temperature
Dust deposits prevent heat radiation and cause high housing temperatures.
Keep the motor free from dirt and dust, etc.
The motors are designed for fin cooling; an external fan draws the cooling air in through the
opening in the fan cover and blows it across the surface of the stator frame.
2.3
Terminal box
In the motor terminal box, alongside the motor connection terminals (terminal board),
additional connecting clamps are available for monitoring equipment. The number of
available terminals is shown in the circuit diagrams. The circuit diagrams are located in the
terminal box.
2.4
Rating plate
The rating plate on the gearbox or geared motor is of coated aluminum foil. It is covered with
a special masking film which ensures permanent resistance to UV radiation and media of all
kinds, such as oils, greases, salt water and cleaning agents.
The adhesive and the material ensure firm adhesion and long-term legibility within the
operating temperature range from -40 °C to +155 °C.
The edges of the rating plate are paint-finished to match the color of the gearbox or motor to
which it is affixed.
In special cases, riveted or bolted metal plates are used.

On gearbox or geared motor versions which are primed or unpainted the rating plate and the
masking film are covered with a paint-protective film. These facilitate repainting without
further preparation, e.g. masking with adhesive tape.
Peeling off the paint-protective film
The paint coat must have fully hardened before the paint-protective film is peeled off (be at
least "touch-proof").
