1 Safety information
1.1 Intended use
These gear units are used to transmit rotary movements. They convert velocity and torque. They are
intended for use as part of a drive system in commercially used plant and machinery. The gear units
must not be operated until it has been established that the plant or machinery can be safely operated
with the gear unit. Suitable protective measures must be provided if failure of a gear unit or a geared
motor could result in a risk to persons. The machine or system must comply with local legislation and
directives. All applicable health and safety requirements must be met. In particular, the Machinery
Directive 2006/42/EC, TR CU 010/2011 and the TR CU 020/2011 must be especially observed in the
relevant areas of application.
The gear units and geared motors to which this manual with installation instructions refers to are
usually components for installation in machines according to the current EC Machinery Directive
2006/42/EG.
In certain individual cases in which the gear unit or the geared motor is considered as a ready-to-
install drive system for specific applications, this drive system is classified as a incomplete machine
according to the current EC Machinery Directive 2006/42/EG. A corresponding declaration of
incorporation is enclosed with the product.
The gear units may not be used in environments in which an explosive atmosphere can occur.
The gear units may only be used according to the information in the technical documentation from
Getriebebau NORD GmbH & Co. KG. Damage to the gear unit may result if the gear unit is not used
as intended and according to the information in the operating and assembly manual. This may also
result in personal injury.
The base or the gear unit mount must be appropriately designed for the weight and torque. All of the
fastenings provided must be used.
Some gear units are equipped with a cooling coil. These gear units may only be operated if the cooling
circuit is connected and in operation.
1.2 Do not make any modifications.
Do not make any structural modifications to the gear unit. Do not remove any protective guards.
1.3 Performing inspection and maintenance work
Due to lack of maintenance and damage, malfunctions may occur which can result in personal injury.
• Carry out all servicing and maintenance work at the specified intervals.
• Also note that servicing is necessary after long storage periods prior to commissioning.
• Do not operate damaged gear units. The gear unit must not have any leaks.
1.4 Personnel qualification
All transport, storage, installation, commissioning and maintenance work must be carried out by
qualified specialist personnel.
Qualified specialist personnel are persons who have the training and experience to recognise and
avoid any possible risks.

Gear units – Manual with installation instructions
12 B 1000 en-3921
1.5 Safety for particular activities
1.5.1 Check for transport damage
Transport damage may cause malfunctions of the gear unit, which may cause personal injury. Oil
which escapes due to leaks may cause a slipping hazard.
• Check the packaging and the gear unit for transport damage.
• Do not operate damaged gear units.
1.5.2 Safety information for installation and maintenance
Before starting work on the gear unit disconnect the drive from the power supply and secure it against
accidental switch-on. Allow the gear unit to cool down. Depressurise the cooling circuit lines.
Damaged or defective components, attachment adapters, flanges and covers may have sharp edges.
Wear work gloves and work clothing.
1.6 Hazards
1.6.1 Hazards when lifting
Persons may be injured by falling or swinging gear units. Therefore also observe the following
information:
• Cordon off a wide area around the hazard area. Take care that there is adequate space to avoid
swinging loads.
• Never stand under suspended loads.
• Use adequately dimensioned means of transport which are suitable for the purpose. The weight of
the gear unit can be obtained from the type plate.
• Only lift the gear units by the eye bolts which are provided. The eye bolts must be fully screwed in.
Only pull on the eye bolts vertically, never cross-wise or at an angle. Only use the eye bolts to lift
the gear unit without other components. The eye bolts are not designed for lifting the gear unit with
attachments. Use the eye bolts on both the gear unit and the motor to lift a geared motor.
1.6.2 Hazards due to rotating parts
Rotating parts cause a risk of entanglement. This may lead to severe injuries such as crushing or
strangling.
• Provide contact protection. In addition to shafts, this also applies to fans as well as drives and
driven elements such as belt drives, chain drives, shrink discs and couplings. Take possible run-on
of the machine into consideration for the design of protective devices.
• Do not operate the drive without covers or hoods.
• Secure the drive to prevent activation during installation and maintenance work.
• For test operation do not switch on the drive without an installed driven element or secure the
motor shaft key.
• Also observe the safety information in the operating and installation instructions provided by
manufacturers of components supplied.

B 1000 en-3921 13
1.6.3 Hazards due to high or low temperatures
The gear unit may heat up to 90 °C during operation. Touching hot surfaces or contact with hot oil may
result in burns. At very low ambient temperatures freezing may occur on contact.
• Only touch the gear unit when wearing gloves after operation or at very low ambient temperatures.
• Before starting maintenance work, allow the gear unit to cool down sufficiently after operation.
• Provide a contact guard if there is a risk that persons may touch the gear unit when it is in
operation.
• Bursts of hot oil mist may be emitted from the pressure vent screw during operation. Provide a
suitable guard so that persons cannot be injured by this.
• Do not place any flammable materials on the gear unit.
1.6.4 Hazards due to lubricants and other substances
Chemical substances which are used with the gear unit may be toxic. Eye injuries may result if these
substances enter the eyes. Lubricants and adhesives may cause skin irritation.
Oil mist may escape when vent screws are opened.
Due to lubricants and conservation materials, gear units may be slippery and slip out of the hands.
There is a slipping hazard from spilled lubricants.
• When working with chemical substances wear chemical-resistant gloves and work clothing. Wash
your hands after working.
• Wear protective goggles if there is a possibility of splashed chemicals, for example when filling oil
or during cleaning work.
• If chemicals enter the eyes, rinse with large amounts of cold water immediately. Consult a
physician in case of symptoms.
• Observe the safety data sheets for the chemicals. Keep the safety data sheets in the vicinity of the
gear unit.
• Collect spilled lubricants immediately with a binding agent.
1.6.5 Hazards due to noise
Some gear units or attached components may cause hazardous noise levels during operation. Wear
hearing protection if work has to be carried out close to such gear units.
1.6.6 Hazards due to pressurised coolants
The cooling system is under high pressure. Damage or opening a cooling line which is under pressure
may result in injury. Depressurise the cooling circuit before working on the gear unit.

more oblique than 45° to the vertical.
• Note the centre of gravity of the gear unit.
Only use the eyebolts attached to the gear unit for transport. If geared motors have an additional
eyebolt attached to the motor, this must also be used.
Transport the gear unit with care. Impacts to the free ends of shafts may cause internal damage to the
gear unit.
No additional loads must be attached to the gear unit.
Use suitable aids such as cross-beams or similar to facilitate transportation of the gear unit. Gear units
may only be transported with shackles and lifting strapschains at an angle of 90° to 70° to the
horizontal.
3.2 Storage and downtimes
3.2.1 General measures

3.2.2 Storage and downtimes in excess of 3 months
Note the following measures in addition to Section 3.2.1 "General measures".
• Repair damages to the coating. Check if a corrosion protection agent has been applied to the
flange bearing surfaces, the shaft ends and the unpainted surfaces. If required, apply a suitable
corrosion protection agent to the surfaces.
• Seal all openings on the gear unit.
• The output shaft must be rotated by at least one revolution every 3 months so that the contact
position of the gear teeth and the roller bearings are changed.
3.2.3 Storage and downtimes in excess of 9 months
Under certain conditions, storage of 2 to 3 years is possible. The specified storage duration is for
guidance only. The actual storage duration depends on the local conditions. Note the following
measures in addition to Sections 3.2.1 "General measures"and 3.2.2 "Storage and downtimes in
excess of 3 months".
Gear units can be supplied prepared for long-term storage. The gear units are completely filled with
lubricant, have VCI corrosion protection agent mixed with the gear oil or are filled with small quantities
of VCI concentrate. The adhesive label on the housing shows the respective information.
Conditions of the gear unit and storage area for long-term storage prior to commissioning:
• Store the gear unit at a temperature in the range of -5 °C to +40 °C without severe temperature
fluctuations.
• Check if the sealing cord in the vent screw is in place. It must not be removed during storage.
• Store the gear unit in a dry space. With a relative humidity less than 60%, the gear unit can be
stored for up to two years; with a relative humidity less than 50%, storage of up to three years is
possible.
• For gear units, which are filled with VCI concentrate for long-term storage, the VCI concentrate
must be renewed after 2 years and distributed in the oil by rotating the shaft.
• In tropical regions, protect the gear unit against damage by insects.
• Gear unit components such as brakes, couplings, belt drive, and cooling units must be protected
for a long-term storage in accordance to their operation instructions.
In addition to the preparations listed in 4 "Commissioning", the following measures are necessary
before commissioning:
• Check the gear unit for external damage.
• After storage of more than 2 years, or with storage temperatures outside of the permissible range
from -5 °C to +40 °C, replace the lubricant in the gear unit before commissioning.
• If the gear unit is completely filled, the oil level must be reduced according to the mounting position.
For the lubricant quantity and lubricant type, refer to the information on the name plate.
• For gear units without oil filling, the oil level must be refilled and checked according to chapter 5.2.3
"Checking the oil level" before commissioning. The VCI concentrate may remain in the gear unit.
The VCI concentrate is not mixable with polyglycol-based lubricants (PG oils). If PG oils are used,
the VCI concentrate must be removed from the gear unit. When using VCI additive, only use the oil
types which are specified on the name plate and are approved by Getriebebau NORD (see chapter
7.2.2 "Gear oils").
• For the option with manual re-lubrication, switch the bearing grease after a storage of more than 2
years. The service life of the grease is reduced after a storage time or gearbox shutdown of more
than 9 months (see chapter 5.2.6 "Re-greasing (Option: VL2, VL3, W, AI, AN)").
• Gear units filled with VCI concentrate for long-term storage are fully closed. Take care that the vent
is fitted and released as necessary prior to commissioning.

3.3 Preparing for installation
3.3.1 Check for damages
Please examine the delivery for transport and packaging damage immediately on receipt. Pay
particular attention to radial shaft seals and sealing caps. Report any damage to the carrier
immediately.
Do not put the drive into operation if damage such as leaks are visible.
3.3.2 Remove corrosion protection agents
All bare metal surfaces and shafts of the drive are protected with corrosion protection agents before
shipping.
Thoroughly remove corrosion protection agents and any dirt (e.g. colour residues) from all shafts,
flange surfaces and gear unit attachment surfaces before assembly.
3.3.3 Check rotational direction
If an incorrect rotational direction may result in damage or potential risk, check for the correct
rotational direction of the output shaft during a test run before attaching it to the machine. Ensure the
correct rotational direction during operation.
For gear units with an integrated back stop, switching the drive motor to the blocked direction of
rotation, may result in damage to the gear unit. 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, ensure, e.g. by testing the field of rotation, that the
gear unit can only operate in the direction of rotation.
For further explanations refer to Catalogue G1000 and document WN 0-000 40.
3.3.4 Check ambient conditions
Make sure that no aggressive or corrosive substances which attack metal, lubricants or elastomers
are present at the installation site or are subsequently expected during operation. If such substances
are to be expected, contact Getriebebau NORD.
The gear unit, especially its radial shaft seals should be protected from exposure to direct sunlight.
The standard permissible ambient temperature range for synthetic gear unit oils (CLP PG … and
CLP HC…) is –20 °C to +40 °C. This temperature range can be extended according to the lubricant
table (see chapter 7.2.2 "Gear oils"), if all mounted materials of the gear unit and the application-
related speed, torques and modes of operation allow this. Note the project planning documents of the
order for this. In case of doubt, ask Getriebebau NORD.
For mineral oil (CLP), the permissible ambient temperature range in accordance to the above stated
lubricant table is restricted. The lubricant type is indicated on the name plate (see chapter 2.2 "Name
plate ").
For installation altitudes above 1000 m above sea level, the permissible speed and torques may be
reduced. Note the project planning documents of the order for this. In case of doubt, ask Getriebebau
NORD.

3.3.5 Drives with nsd tupH surface treatment
Drives with nsd tupH surface treatment must be electrically decoupled from other components by the
use of non-conductive intermediate layers in order to prevent galvanic corrosion.
3.3.6 Installing the oil expansion chamber (Option: OA)
Mount the oil expansion chamber (Option OA) according to document WN 0-530 04. For gear units
with a M10x1 vent screw or pressure relief vent, document WN 0-521 35 must also be observed
during installation.
