electrical operating area (restricted access) with concrete floor.

Electrical Safety - general warning

The voltages used in the drive can cause severe electrical shock and/or burns, and 

could be lethal. Extreme care is necessary at all times when working with or adjacent to 

the drive.

Specific warnings are given at the relevant places in this guide.

1.3 System design and safety of personnel

The drive is intended as a component for professional incorporation into complete 

equipment or system. If installed incorrectly, the drive may present a safety hazard.

The drive uses high voltages and currents, carries a high level of stored electrical 

energy, and is used to control equipment which can cause injury.

System design, installation, commissioning and maintenance must be carried out by 

personnel who have the necessary training and experience. They must read this safety 

information and this guide carefully.

The STOP and START controls or electrical inputs of the drive must not be relied 

upon to ensure safety of personnel. They 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.

The drive is not intended to be used for safety-related functions.

Careful consideration must be given to the function of the drive which might result in a 

hazard, either through its 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.
