1.3 Measuringsurface soundpressure level
The gear unit has a measuringsurface soundpressure level at a distance of 1 m, which can be found in
table 1.
The measurement is carried out to DIN EN ISO 9614 Part 2, using the soundintensity method.
The workplace of the operating personnel is defined as the area on the measuringsurface at a distance
of 1 metre in the vicinity of which persons may be present.
The soundpressure level applies to the warmedup gear unit at input speed n1and ouput power PNRL
in accordance with the rating plate, as measurement obtained on the Siemens test bench. If several figures
are given, the highest speed and power values apply.
The measuringsurface soundpressure level includes addon lubrication units, if applicable. With
outgoing and incoming pipes, the flanges are taken as interfaces.
The soundpressure levels stated in the table were obtained by statistical calculation by our Quality Control
Dept. The gear unit can be statistically expected to comply with these soundpressure levels.
If repeat measurements on site do not produce conclusive results with regard to measuring technology,
the measurement obtained on the Siemens test bench will apply.

4.3 Storing the gear unit
The gear unit must be stored in a sheltered place in the position of the original packaging or in the position
of use, placed on a vibrationfree, dry base, and covered over.
When temporarily storing the gear unit and any single components supplied with it,
the preservative agent should be left on them. It must not be damaged, otherwise there
is a risk of corrosion.
Do not stack gear units on top of one another.
If the gear unit is being stored out of doors, it must be particularly carefully covered,
and care must be taken that neither moisture nor foreign material can collect on the
unit. Waterlogging should be avoided.
Unless otherwise agreed by contract, the gear unit must not be exposed to harmful
environmental factors such as chemically aggressive products.
Provision for special environmental conditions during transport (e.g. transport by ship) and
storage (climate, termites, etc.) must be contractually agreed.
4.4 Standard preservation
The gear unit is provided with an interior preservative agent; the free shaft ends are painted for protection.
The properties of the outer paint coat are as follows: Resistant to acids, weak alkalis, solvents,
atmospheric action, temperatures up to 120 °C (briefly up to 140 °C), and to tropical conditions.
The gear unit is normally delivered completely ready, with a priming and a finish coat.
Where gear units are delivered with a priming coat only, it is necessary to apply a finish
coat in accordance with directives applying to the specific application.
The priming coat alone is not suitable to provide a sufficient longterm corrosion
protection.
Ensure that the coat is not damaged!
Any damage may cause failure of the exterior protective coating and corrosion.
Unless otherwise contractually agreed, the durability periods of the interior gearunit
preservation specified in table 2 or 3 will apply, provided the related requirements are adhered
to. The durability period for the exterior preservation and the related requirements can be found
in table 4.
The guarantee period starts on the date of delivery or that of the notice that the item is ready
for shipment.
In case of a storage period other than that indicated in table 2 or 3 and in table 4, the interior and the exterior
preservation must be checked and, as necessary, be repeated (see items 7.3.1 and 7.3.2).

Wear safety gloves and safety glasses!
Any oil spillage must be removed immediately with an oilbinding agent.
For storage periods longer than 24 months (see table 2) or 36 months (see table 3), the interior
preservation of the gear unit must be renewed. The following procedure is recommended:
• Place a suitable container under the oildraining point of the gearunit housing.
• Unscrew the oildrain plug and/or open the oildrain cock and drain the used preservation oil into
a suitable container.
• Dispose of the residue of the preservative oil in accordance with regulations.
• Close the oildrain cock and/or screw in the oildrain plug.
• Unscrew the screw plug.
• Fill the gear unit by way of the venting hole with "Castrol Alpha SP 220 S", until the gears are immersed.
Filling quantity according to the gearunit dimensions (length x width x height) x 0.05.
In all cases the special oil "Castrol Alpha SP 220 S" with additional
corrosionprevention features (addition "S") must be used.
• Screw in the screw plug again.
The gear unit has now been preserved for another period of 24 months.
If the gear unit is to be filled with a PGbased synthetic operating oil after preservation,

5. Technical description
Observe the instructions in section 3, "Safety instructions"!
5.1 General description
The gear unit is supplied as a two or threestage helicalgear unit. It is designed for installation in the
horizontal mounting position. If necessary, it can also be designed for installation in a different position.
The exact design and the corresponding direction of rotation of the gear unit can be found in the drawings
in the gearunit documentation.
The gear unit can be operated in both directions of rotation.
The gear unit is characterised by a low noise level, which is achieved by helical gears with a high contact
ratio and a sounddamping housing.
The good temperature characteristics of the gear unit are achieved by its high degree of efficiency and its
large housing surface area.
The gear unit must be supplied with oil by an addon or external oilsupply system.
5.2 Housing
The housing is in two sections and made of cast iron; if required, it may also be of steel.
The housing is rigid in design and due to its form has excellent noise and temperature characteristics.
The gearunit housing comes with the following equipment:
• Lifting eyes or transport lugs (adequately dimensioned for transport)
• Inspection and/or assembly cover (for inspection)
• Oilsight glass or angular oillevel indicator (for checking the oil level)
• Oildrain plug and/or oildrain cock (to drain the oil)
• Air filter (for venting)
Colour codes for ventilating, oil inlet, oil level and oil drainage:
Airrelief point: yellow Oildraining point: white
Oilfilling point: yellow Lubrication point: red
Oil level: red
