3.2 Storage
For short-term storage before commissioning, please observe the following:
• Store gear units in the fitting position (7.2 "Installation orientation") and secure them against falling,
• Lightly oil bare metal housing surfaces and shafts
• Store in a dry place,
• Temperature in the range from – 5 °C to + 50 °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

3.3 Long-term storage
CAUTION
Injury to persons
Incorrect or excessively long storage may result in malfunctions of the gear unit.
• Perform an inspection of the gear unit prior to commissioning if the permissible storage time has been
exceeded.
For storage or standstill periods in excess of 9 months, Getriebebau NORD recommends the long-term storage
option.
• With the long-term storage option and 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 installation position 7.2 "Installation orientation"and secure 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.
• 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
• The position of the shaft should be changed within 9 months in order to prevent damage to the
bearings or the shaft sealing rings.
