General information and safety notes
1.4 Obligations of the user
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.

10 Operating Instructions, 03/2013, 70000004024300
Technical description
2.1 General description
The gearbox is supplied with one transmission stage.
The gearbox housing is made from die-cast aluminum.
The worm shaft is hardened and ground. The gear is manufactured from high-quality bronze.
All shafts are mounted in roller bearings.
The gearbox is lubricated for life with high-quality synthetic oil.
Radial shaft sealing rings are used in the standard version. At higher ambient temperatures
over +40 °C to +80 °C, shaft sealing rings of temperature-resistant material are used, subject
to contractual agreement.
2.2 Cooling
NOTICE
High housing temperature
2
Dust deposits prevent heat radiation and cause high housing temperatures.
Keep the gearbox free from dirt and dust, etc.
The gearbox does not normally require additional cooling. The generously dimensioned
housing surface is sufficient for dissipating heat losses where there is free convection. If the
housing temperature exceeds a value of +80 °C, please contact Technical Support.
2.3 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.

Technical description
2.4 Surface treatment
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.
2.4 Surface treatment
Standard-version gearboxes are not painted at the factory. If necessary, they can be painted
with any kind of commercially available paint.
ATEX version gearboxes
As standard, the gearbox is not painted. The gearbox is optionally delivered
complete with primer and paint finish.
ATEX version gearboxes
When applying conductive paint, the operating company must ensure that the
paint remains in a perfect state. The paint finish must be checked at intervals of
approximately 2 - 3 years.
ATEX version gearboxes
An excessively high electrostatic charge must be avoided.
Ensure that highly active mechanisms that cause the paint finish to generate a
charge are avoided.
Highly active mechanisms that can generate charges:
fast airflow
with a high dust content directed past the gearbox
sudden escape of compressed gases containing particulates
harsh abrasi
ve processes (not referring to manual cleaning / wiping with
cleaning rags).
NOTICE
Sealing lips must not come into contact with paint
Cover the shaft sealing rings.
