Safety Considerations

Safety Precautions

This product is intended for professional integration into a complete system. If you install the product incorrectly, it may

present a safety hazard. The product and system may use high voltages and currents, carry a high level of stored electrical

energy, or control mechanical equipment that can cause injury.

You should give close attention to the electrical installation and system design to avoid hazards either in normal operation or

in the event of equipment malfunction. System design, installation, commissioning and maintenance must be carried out by

personnel who have the necessary training and experience. Read and follow this safety information and the instruction manual

carefully.

Enclosure

This product is intended to be mounted in an enclosure which prevents access except by trained and authorized personnel,

and which prevents the ingress of contamination. This product is designed for use in an environment classified as pollution

degree 2 in accordance with IEC664-1. This means that only dry, non-conducting contamination is acceptable.

Setup, Commissioning and Maintenance

It is essential that you give careful consideration to changes to drive settings. Depending on the application, a change could

have an impact on safety. You must take appropriate precautions against inadvertent changes or tampering. Restoring default

parameters in certain applications may cause unpredictable or hazardous operation.

Safety of Machinery

Within the European Union all machinery with which this product is used must comply with Directive 89/392/EEC, Safety

of Machinery.

The product has been designed and tested to a high standard, and failures are very unlikely. However the level of integrity

offered by the product’s control function – for example stop/start, forward/reverse and maximum speed – is not sufficient for

use in safety-critical applications without additional independent channels of protection. All applications where malfunction

could cause injury or loss of life must be subject to a risk assessment, and further protection provided where needed.

General warning

Failure to follow safe installation guidelines can cause death or serious injury. The voltages used in this unit can cause severe electric

shock and/or burns, and could be lethal. Extreme care is necessary at all times when working with or adjacent to this equipment. The

installation must comply with all relevant safety legislation in the country of use.

AC supply isolation device

The AC supply must be removed from the drive using an approved isolation device or disconnect before any servicing work is

performed, other than adjustments to the settings or parameters specified in the manual. The drive contains capacitors which remain

charged to a potentially lethal voltage after the supply has been removed. Allow at least 3 minutes after removing the supply before

carrying out any work which may involve contact with electrical connections to the drive.

Products connected by plug and socket

A special hazard may exist where the drive is incorporated into a product which is connected to the AC supply by a plug and socket.

When unplugged, the pins of the plug may be connected to the drive input, which is only separated from the charge stored in the bus

capacitor by semiconductor devices. To avoid any possibility of electric shock from the pins, if they are accessible, a means must be

provided for automatically disconnecting the plug from the drive (that is, a latching contactor).

Grounding (Earthing, equipotential bonding)

The drive must be grounded by a conductor sufficient to carry all possible fault current in the event of a fault. The ground connections

shown in the manual must be followed.

Fuses

Fuses or over-current protection must be provided at the input in accordance with the instructions in the manual.

Isolation of control circuits

The installer must ensure that the external control circuits are isolated from human contact by at least one layer of insulation rated for

use at the applied AC supply voltage.
