3.3 Long-term storage
For storage or standstill periods in excess of 9 months, Getriebebau NORD recommends the long-
term storage option. With the use of the measures listed below, storage for up to 2 years is possible.
As the actual influences on the unit greatly depend on the local conditions, these times should only be
regarded as guide values.
Conditions of the gear unit and storage area for long-term storage prior to commissioning:
• Store in the fitting position (please see chapter 7.1 "Versions and maintenance")and secure them
against falling.
• Transportation damage to the external paint must be repaired. Check that a suitable rust inhibitor is
applied to the flange bearing surfaces. If necessary apply a suitable rust inhibitor to the surfaces.
• Gear units with the long-term storage option are completely filled with lubricant or have VCI
corrosion protection agent mixed with the gear oil (see adhesive label on the gear unit, or are not
filled with oil, but rather with small quantities of VCI concentrate.
• The sealing band in the vent plug must not be removed during storage. The gear unit must remain
sealed tight.
• Store in a dry place.
• In tropical regions the drive unit must be protected against damage by insects.
• Temperature in the range from – 5 °C to + 40 °C without large fluctuations.
• Relative humidity less than 60 %.
• No direct exposure to sunlight or UV light.
• No aggressive, corrosive substances (contaminated air, ozone, gases, solvents, acids, alkalis,
salts, radioactivity etc.) in the immediate vicinity.
• No vibration or oscillation
Measures during storage or standstill periods
• If the relative humidity is < 50 % the gear unit can be stored for up to 3 years.
Measures before commissioning
• Inspect the gear unit before commissioning.
• If the storage or standstill period exceeds 2 years or the temperature during short-term storage has
greatly deviated from the standard range, the lubricant in the gear unit must be replaced before
commissioning.
• If the gear unit is completely filled, the oil level must be reduced before commissioning.
• For gear units without oil filling, the oil level for the version must be filled before commissioning.
The VCI concentrate may remain in the gear unit. Lubricant quantities and types must be filled
according to the details on the type plate.

Please examine the delivery for transport and packaging damage immediately on receipt. The drive
unit must be examined and may only be installed if no damage is apparent. In particular the shaft
sealing rings and sealing caps must be inspected for damage. Report any damage to the carrier
immediately. Gear units with transport damage must not be commissioned.
All bare metal surfaces and shafts of the gear units are protected against corrosion with oil/grease or
corrosion protection agents before shipping.
Thoroughly remove all oil / grease or corrosion protection agents and any dirt from the shafts and
flange surfaces before assembly.
In applications where an incorrect rotational direction may result in damage or potential risk, the
correct rotational direction of the output shaft must be established by test running the drive when
uncoupled and ensured for subsequent operation.
Gears with integrated back stops are marked with arrows on the drive/driven sides. The arrows point
in the rotation direction of the gear unit. When connecting the motor and during motor control, it must
be ensured that the gear unit can only operate in the direction of rotation. (For further explanations
refer to Catalogue G1000 and WN 0000 40.)
Ensure that no aggressive or corrosive substances which attack metal, lubricants or elastomers are
present in the area surrounding the installation site or are subsequently expected during operation.
Gear units with nsd tupH surface treatment must be electrically decoupled by the use of non-
conductive intermediate layers. In case of doubt, please contact Getriebebau NORD and take the
recommended action.
Oil expansion tanks (Option OA) must be fitted in accordance with works standard WN 0-530 04. For
gear units with an M10 x 1 vent plug, document Works Standard WN 0-521 35 must be also be
observed during installation.
Oil level tanks (Option OT) must be fitted in accordance with Works Standard WN 0-521 30.
If the gear unit is equipped with venting, the venting or pressure venting must be activated before
commissioning. To activate, remove the transport securing devices (sealing cord). Position of the vent
screw (please see chapter 7.1 "Versions and maintenance").

Special pressure vents are supplied as loose parts. Before commissioning, the vent screws must be
replaced with the special pressure vents which are supplied as loose parts. This is done by
unscrewing the vent fitting and replacing it with the special pressure vent and seal (please see chapter
7.1 "Versions and maintenance"). Double gear units consist of two single units and are equipped with
2 oil chambers and possibly 2 pressure vents.
