5.5- Check the Voltage Supply ;
ATEX conforming gear units are supplied by YILMAZ without motor. The motor that will be
fitted must have ATEX certificate and the instruction manual of the electric motor provider
must be observed. Observe the name plate of the electric motor and the instructions of
the supplier. Use experienced electric technician. The gearbox and the motor must be
grounded to prevent potential differences of earth and gearbox / motor.
Using wrong connection or voltage can damage the electric motor or environment. The
electric connection must be done by experienced electric technician.
The gearbox and the motor must be grounded to prevent potential difference of earth and
gearbox / motor after installation before starting up.
5.6- Check the Mounting Position ;
The mounting position must be in accordance with the mounting position mentioned on the
name plate. If different please contact YILMAZ REDUKTOR for possibilities of using in a
different mounting position then indicated on the name plate without informing YILMAZ
REDUKTOR will cancel the ATEX conformity and YILMAZ does not take any
responsibility.
Do not mix synthetic oils with mineral oils which can cause serious damage on the gear
unit.
5.7- Usage of Breather Plug ;
Breather plugs are supplied as a standard part for ATEX conforming gear units. The
breather plug is attached to the gear unit and must be changed with the most top plug ac-
cording to the mounting position. Take out the plug over the gear box and replace it with
the supplied breather plug after assembling to its place and before start-up.
The breather plugs are opened at 0.2 bar pressure.
After opening the plugs use Locktite when locking them again.
All plug points are not machined. Only plugs according mounting position is machined. If
no mounting position is mentioned by ordering the standard M1 position plugs are
machined.

5.8- Check the oil level ;
On the mounting position tables the oil level plug is shown. Please refer to those
tables and be sure that the oil level is correct according the mounting position. Use
a wire as shown below for checking the oil level entering from the level plug. The oil
level must be within 3mm from the plugs entering point as shown below. If you need
to adjust the oil level refer to the oil tables given on this manuel and be sure you are
using the correct oil. Observe the nameplate for the correct oil.
After checking the oil level of gear unit tighten the screws very carefully to prevent oil
leakage.
Do not mix synthetic oils with mineral which can cause serious damage on the
gear unit.
5.9- Check shaft ends and mounting faces;
Before you start to installing be sure that all the connection elements are free of oil
and dust. The output shaft may be protected by anti-corrosion oil. Please remove this
using available solvents on your market. By using this do not touch sealing lips or
painting of the housing.
5.10- Cover abrasive ambient;
If the gear unit will be placed on a abrasive ambient be sure that the output seals
are covered so that no abrasive material, chemicals or water touches the seals. Any
pressure coming from outside over the seals can cause that the out staying sub-
stances to enter the gearbox and cause serious damage to the gear unit. If pressure
or abrasive material can not be prevented from
coming over the sealing, contact YILMAZ for solutions.
Abrasive material, chemicals, water, positive or negative pressure exceeding 0,2 bar
can affect or damage the sealing lip or output shaft. Inside entering substances from
the seals can cause serious damage to the gear unit.
To avoid temperature rising in case of dust cover on the housing of the gearbox, the
housing have to be cleaned regularly.
5.11- Check accessibility to filling, breather and drain plugs;
The filling, breather and drain plugs must be freely accessible for further checking
and service.

6- Mechanical Installation
The mounting plate must be rigid enough not allowing torsions, flat enough to prevent
strains by tightening the bolts and stable enough not allowing vibrations. By using chain
drives this becomes much more important because of the polygon effect on chain drives.
According to your connection elements the maximal permitted radial and axial load of the
gear unit must be in accordance with your application. Check the product catalogue for
permitted radial loads and calculation.
If the output or input shaft is overloaded by radial or axial loads it can cause serious dam-
age to the gear unit.
Secure the gear unit using 8.8 or higher quality bolts.
All bolts are locked by use of locktide adhesives or gear-shims on the gearbox. By assem-
bling the gear unit locktides adhesives or gear-shims must be used to prevent loosening
of bolts.
Cover all the turning parts from human entering or touching. Turning parts can cause se-
vere or fatal injuries.
For different kind of basic installations refer to the following illustrations.
Only ATEX-approved input and output elements are allowed to be used, assuming the ele-
ments are subject to Directive 94/9/EC
6.1- Installing gear units in category II2G/D-II3G/D
Explosion-proof gear units comply with the design requirements for unit group II, catagory
2G,2D,3D,3G. These units are intended for use in zones 1 and 21.
The gear units in catagory II2D must be used in ambient teperature between -20 C to +40
C only. If different ambient conditions this must be informed before order and the name
plate must be in accordance with the ambient conditions.
The temperature class depends on the speed, type and mounting position of the gearbox
and is indicated on the name plate. Temperature classes from T4 to T6 are provided by
YILMAZ REDUKTOR.
The surface temperature of the gearbox must not exceed the provided max. surface tem-
perature on the name plate. After all installations finished and the gearbox is started up
according this manual let the gear unit run 4 hours at full load and check the surface tem-
perature and the ambient temperature. Check the following;
