Close attention is required to the electrical installation and the system design to avoid hazards either in normal operation or in the event of equipment

malfunction. System design, installation, commissioning/start-up and maintenance must be carried out by personnel who have the necessary training

and experience. They must read this safety information and this Design Guide carefully.

The STOP and Safe Torque Off (STO) functions of the drive do not isolate dangerous voltages from the output of the drive or from any external option

unit. The supply must be disconnected by an approved electrical isolation device before gaining access to the electrical connections.

With the sole exception of the Safe Torque Off (STO) function, none of the drive functions must be used to ensure safety of personnel, i.e.

they must not be used for safety-related functions.

Careful consideration must be given to the functions of the drive which might result in a hazard, either through their intended behavior or through

incorrect operation due to a fault. In any application where a malfunction of the drive or its control system could lead to or allow damage, loss or injury,

a risk analysis must be carried out, and where necessary, further measures taken to reduce the risk - for example, an over-speed protection device in

case of failure of the speed control, or a fail-safe mechanical brake in case of loss of motor braking.

The Safe Torque Off (STO) function may be used in a safety-related application. The system designer is responsible for ensuring that the complete

system is safe and designed correctly according to the relevant safety standards.

1.4

Environmental limits

Instructions in this Design Guide regarding transport, storage, installation and use of the drive must be complied with, including the specified

environmental limits. Drives must not be subjected to excessive physical force.

1.5

Access

Drive access must be restricted to authorized personnel only. Safety regulations which apply at the place of use must be complied with.

1.6

Fire protection

The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided. For further information, refer to section 3.2.5 Fire

protection on page 29.

1.7

Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national wiring regulations, accident prevention regulations and

electromagnetic compatibility (EMC) regulations. Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses

or other protection, and protective ground (earth) connections.

This guide contains instructions for achieving compliance with specific EMC standards.

Within the European Union, all machinery in which this product is used must comply with the following directives:

2006/42/EC: Safety of machinery.

2004/108/EC: Electromagnetic Compatibility.
