Industrial gear units – Operating and Assembly Instructions
12 B 1050 en-4419
1 Safety information
1.1 Intended use
These gear units are used to transmit and transform rotary movements. 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 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 modifications to the gear unit. Do not remove any protective devices.
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.

1 Safety information
B 1050 en-4419 13
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.
• Gear units may only be transported with shackles and lifting straps/chains at an angle of 90° to 70°
to the horizontal. Do not use the eye bolts on the motor for lifting if a motor is fitted to the gear unit.
The eye bolts are not designed for lifting the motor with heavy attachments. Pay attention to the
section 3.1 "Transporting the gear unit".
1.6.2 Hazards due to rotating parts
Rotating parts cause a risk of entanglement. Therefore provide a contact guard. In addition to shafts,
this also applies to fans as well as drives and drive elements such as belt drives, chain drives, shrink
discs and couplings.
For test operation do not switch on the drive without an installed drive element or secure the parallel
key.
Take possible run-on of the machine into consideration for the design of protective guards.

Industrial gear units – Operating and Assembly Instructions
14 B 1050 en-4419
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.
