General safety and operating instructions
1. General
Depending on its
protection class, the device may have live, bare,
moving or rotating parts or hot surfaces during operation,.
Unauthorised removal of covers, improper use, incorrect installation or
operation causes a risk of serious personal injury or material damage.
All transport, installation, commissioning and maintenance work must be
carried out by qualified specialist personnel (national accident
prevention regulations must be observed).
Within the meaning of this basic safety information, qualified specialist
person
nel are persons who are familiar with the installation, assembly,
commissioning and operation of the product and who have the training
and experience to recognise and avoid any hazards and risks.
2. Intended use
NORD products may only be used according to
the information in the
catalogue and the associated technical documentation.
Compliance
with the operating and installation instructions is a
prerequisite for fault-free operation
and for the fulfilment of any
warranty claims. These operating and installation instructions must
be read and understood before working with the device!
These operating and installation instructions contain important
information about servicing. They must therefore be kept
in close
proximity to the device.
All details regarding te
chnical data and permissible conditions at the
installation site must be complied with.
3. Transport, storage
Information regarding transport, storage and correct handling must be
complied with.
4. Installation
The device must be protected against impermissible loads. In particular,
during transport and handling, components must not be deformed or
changed.
Touching of electronic components and contacts must be
avoided.
5. Electrical connection
When working on live three-
phase motors, the applicable
national accident prevention regulations must be complied with
(e.g. BGV A3, formerly VBG 4).
The electrical installation must be implemented according to the
applicable regulations (e.g. cable cross-
section, fuses, earth
lead connections).
Information regarding EMC-compliant installation –
such as
shielding, earthing and installation of cables –
can be found in
the three-
phase motor documentation. Compliance with the limit
values specified in the EMC regulations is the responsibility of
the manufacturer of the system or machine.
6. Operation
Appropriate safety measures must be taken for applications
where failure of the device may result in injury.
Where necessary, systems in which NORD devices are installed
must be equipped with additional monitoring and protective
equipment according to the applicable safety requirements, e.g.
legislation concerning technical equipment, accident prevention
regulations, etc.
All covers and guards must be kept closed during operation.
7. Maintenance and repairs
After the de
vice has been disconnected from the power supply,
live equipment components and power connections should not
be touched immediately, because of possible charged
capacitors.
Further information can be found in this documentation.
These safety instructions must be kept in a safe place!

3.1 Transporting the gear unit
WARNING Hazard due to heavy loads
Severe injuries and material damage due to falling, swinging or tipping heavy loads are possible.
• To prevent injury, the danger area must be generously cordoned off.
• Standing under the gear unit during transport is extremely dangerous.
• Use adequately dimensioned and suitable means of transportation. Lifting tackle must be designed for the
weight of the gear unit. The weight of the gear unit can be obtained from the dispatch documents.
• If geared motors have an additional eyebolt attached to the motor, this must not be used.
• Only the four ring bolts provided may be used for transporting the gear unit.
CAUTION
Slipping hazard
Transport damage to the gear unit or gear unit components may result from the leakage of lubricants. There is a
slipping hazard due to leaked lubricants.
• The drive unit must be inspected and may only be installed if no transportation damage or leaks are visible. In
particular the radial seals and the sealing caps must be inspected for damage.
NOTICE Gear unit damage
Damage to the gear unit due to improper use is possible.
• Prevent damage to the gear unit. Impacts to the free ends of the shafts may cause internal damage to the
gear unit.
• The ends of the shafts must not be used for transportation, as this may seriously damage the gear unit.
An additional lashing point may be required for versions which deviate greatly from the following
illustrations, or in the case of additional drive units and components.
In this case, please contact NORD Service.
