General information and safety notes
1.4 Installation notes
10
The motors have been designed for theapplication described in Section Technical data
(Page 63). Do not operate the motor outside thespecified power limit. Other operating
conditions must be contractually agreed.
Never use degrees of protection ≤IP54 outdoors. Air-cooled versions are designed for
ambient temperatures of -20 °C to +40 °C as standard 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 Installation notes
Prerequisites for smooth, vibration-free running
•Stable foundation design
•Precise alignment of the machine
•Correct balancing of theparts to be mounted on theshaft extension
•Compliance with vibration severity values according to ISO 20816-1
Vibration severity
Due to the influencing variables listed below, the vibration response of thesystem atthe
location of usecan lead to increased vibration severity on the drive unit:
•Transmission elements
•Installation conditions
•Alignment and installation
•Effects of external and internal oscillation
The vibration severity values specified in accordance with ISO 20816-1 must not be exceeded
at any point on the surface of the drive. This ensures problem-free operation and a long
service life.
Maximum permissible vibration severity
Observe the values for the maximum permissible radial and axial oscillation vibration severity
in the following table. Radial/axial refers to the motor axes.
Vibration frequency
Vibration value
< 6.3 Hz
Vibration displacements≤0.16 mm
6.3 Hz to 250 Hz
Vibration velocity vrms ≤4.5 mm/s

Vibration velocity
Vibration acceleration
Vibration velocity vrms ≤4.5 mm/s

Resonant frequencies
Resonance can occur in the speed range of the geared motor depending on the machine to
be driven.
Operation in resonancecauses increased noise and vibration levels.
Adherence to the maximum permissible vibration severity is always required.
Operation in the resonant frequency leads to a reduced service life of the geared motor,
irrespective of adherence to the maximum vibration severity.
Continuous operation in the resonant frequency must be avoided.
1.5 Geared motor with encoder for safety-relevant applications
For a MOTOX geared motor with encoder for safety-relevant applications, it is crucial that
you observe the operating instructions BA 2730.These operating instructions arevalid for the
functionally safe encoders that are mounted ontoMOTOX geared motors. The functionally
safe encoders are in compliance with the relevant standards for safety-relevant applications
listed in the declaration of conformity of BA 2730.
The SMOTOX geared motor with functionally safe encoder has a signal yellow marking on
the fan cover. Marking SI04 for thefunctionally safe encoder is stamped on the rating plate.
The safety level is marked on the functionally safe encoder.

1.6 Obligations of the user
The company operating the unit must ensure thatall persons assigned to work on the geared
motor have read and understood these operating instructions and that they comply with
them in all points in order to:
•Eliminate the risk to life and limb of users and others
•Ensurethe operational safety of the geared motor.
•Avoid disruptions and environmental damage through incorrect use.
Comply with the following safety instructions:
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, carefully comply with the relevant regulations for work safety and
environmental protection.

Take appropriate protective measures to prevent accidental contact with rotating drive parts,
such as couplings, gear wheels or belt drives.
Take appropriate protective 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. Immediately remove any spilt
oil with an oil-binding agent.
Do not carry out any welding work on the geared motor. Do not usethe geared motor as a
grounding point for welding operations.
Carry out equipotential bonding in accordance with applicable regulations and directives by
electrotechnology specialists.

Replace damaged bolts with new bolts of thesame type and strength class.
Steinlen Elektromaschinenbau GmbH accepts the warrant y only for original spare parts.
The manufacturerwho installs the geared motors in a plant must include the regulations
contained in the operating instructions in its own operating instructions.
Make surethat you observe themaximum permissible vibration levels specified in
ISO 20816-1 (zone limit A) during operation.
1.7 The five safety rules
For your own personal safety and to prevent material damage when carrying out any work,
always observe the safety-relevant instructions and the following five safety rules according
to EN 50110-1 Working in a voltage-free state. Apply the five safety rules in the sequence
statedbefore startingwork.
Five safety rules
1. Disconnect.
Also disconnect the auxiliary circuits, for example the anti-condensation heating.
2. Secureagainst reconnection.
3. Verify absence of operating voltage.
4. Ground andshort circuit.
5. Cover or safeguardneighboring live parts.
After the work has been completed, undo the measures taken in the reverse order.

2.2 Cooling
NOTICE
Dust deposits prevent heat radiation
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the motor free from dirt, dust etc.
The motor is designed to be cooled by means of fins. An external fan draws in the cooling air
through the aperture in the fan cover and blows the air over the surfaceof thestator
housing.
2.3 Backstop at the motor
NOTICE
Service life limited
Drive speeds below 1 000 rpm or frequent startingand stopping operations
(≥20 starts / stops per hour) will limit service life.
Ensurethat the backstop is replaced in time when frequent startingand stopping operations
are performed.
NOTICE
Damage or destruction due to incorrect direction of rotation
Do not runthe motor against the backstop.
Note the directional arrow on the motor.
Note
The backstop is not suitable for ambient temperaturesunder -25 °C.
The motor can be fitted with a mechanical backstop. The backstop permits only the correct
direction of rotation during operation. The motor is marked by an arrow pointing in the
corresponding direction.
The backstop is fitted with centrifugally operated sprags. When the motor is running in the
specified direction, the inner ring and the cage with the sprags also rotate while the outer
ring remains stationary.

Resetting the parameters to their factory settings
Resetting the parameters to their factory settings means that the motor parameter values
deviate from the required values. Restore the relevant motor parameter values.
Procedure
1. Set the value of parameter p0010 to 30.
2. Set the value of parameter p0970 to 10.
Detailed information can be found in the G110M List Manual.
2.6 Rating plate
The rating plate on the gearbox or geared motor is of coated aluminum foil. The rating plate
is glued using a special masking film. The film ensures permanent resistance to UV radiation
and media of all kinds, such asoils, greases, salt water and cleaning agents.
The adhesive and the material ensurefirm 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.
2.7 Surface treatment
2.7.1 General information on surface treatment
All paint finishes are sprayed on.
NOTICE
Failure of the external protection
If the paint finish is damaged, the geared motor may corrode.
Do not damage the paint finish.
Note
Information about the ability to be repainted does not guarantee the quality of the paint
product supplied by your supplier.
Only the paint manufacturer is liable for the quality and compatibility.
