Description of the gear unit
The technical data of the gear unit/geared motor can be found
in the order confirmation. This refers to the lubricant used that
is specified on the nameplate of the gear unit. Other technical
data as well as dimensional drawings can be found in the ap-
propriate catalog from STOBER.
3.1 ATEX identification
The gear unit is identified on the ATEX nameplate as follows.
1) According to IEC 60079-10-X

Transportation and storage
When transporting the gear units/geared motors make certain
not to damage the shafts and bearings with impacts.
Sling the gear with a suitable support cable directly in the gear
unit housing. In addition sling the motor mounted on the gear
unit and make sure that there is no diagonal pull.
The gear units/geared motors may only be stored in en-
closed, dry rooms. Storage in open air areas with a roof is only
permitted for brief periods. Protect the gear units/geared mo-
tors from all damaging environmental effects and mechanical
damage.
Avoid extreme temperature fluctuations with high relative hu-
midity when the gear units/geared motors are being stored
temporarily to prevent formation of water from condensation.
Long-term storage
If long-term storage is planned, protect the bare parts of the
gear unit against corrosion. Completely fill the variable speed
drive with integrated spur gear stage with lubricant that is
specified on the nameplate. Reduce the lubricant to the cor-
rect filling quantity according to the nameplate before com-
missioning the drive.

Mounting
Inspect the delivery for any transport damage immediately af-
ter you receive it. Notify the transport company of any dam-
age immediately. Do not operate damaged gear units/geared
motors.
Remove the packaging of the gear unit/geared motor and dis-
pose of it according to the applicable legal requirements on
site.
Check the following before installing the gear unit:
•
Do the specifications on the ATEX nameplate of the gear
unit (gear group, category, EPL, temperature class and
maximum surface temperature) correspond with the
zone subject to explosion hazard where the gear unit is
to be used?
•
Is the gear unit installed in a zone that is not subject to ex-
plosion hazard?
•
Do all drive and output elements to be mounted have ap-
propriate explosion protection?
NOTICE
The lip seals of the shaft seal rings can be damaged by
the use of solvents.
When removing the corrosion protection, make sure that
the lip seals of the shaft seal rings do not come into con-
tact with solvents.
Completely remove all corrosion protection on the shaft ends
prior to installation.
5.1 Installation positions
The version of the gear unit and the lubricant amount filled at
the factory is matched to the installation position of the gear
unit. The gear unit may therefore only be installed at the in-
stallation position specified in the order confirmation. A sign
on the gear units shows which gear unit side must point down-
wards.
5.2 Installation of gear unit
Mount the gear unit on an even, vibration-reducing and tor-
sion resistant substructure. Use screws of strength class 10.9
to fasten the gear unit via the pitch circle diameter. Use
screws of strength class 8.8 for all other fastening types.
Observe the following for assembly:
•
The housing feet and attachment area may not be braced
against each other.
•
The permitted shear and axial forces may not be exceed-
ed.
•
Screws for filling and draining the lubricant as well as
available ventilation valves must be freely accessible.
•
Earthing the gear unit housing via metal components of
the system must be ensured.
