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!

1.1 General information

Read the Operating Manual carefully prior to performing any work on or putting the gear unit into

operation. Strict compliance with the instructions in this operating manual is essential. This Operating

Manual and all associated special documentation must be kept in the immediate vicinity of the gear

unit.

Getriebebau NORD accepts no liability for personal injuries or damage to material or assets which

result from failure to observe the operating instructions, incorrect operation, deployment of

inadequately qualified personnel, improper use or modifications to the gear unit, including installed or

attached components.

General wearing parts, e.g. radial seals are excluded from the warranty.

If additional components are attached to or installed on or in the gear unit (e.g. motor, cooling system,

pressure sensor etc.) or components (e.g. cooling system) are supplied with the order, the operating

instructions for these components must be observed.

If geared motors are used, compliance with the Motor Operating Manual is also necessary.

If you do not understand the contents of this Operating Manual or additional operating instructions,

please consult Getriebebau NORD!
