1 Safety information
1.1 Warnings, cautions and notes
1.2 Electrical safety - general warning
The voltages used in the field controller 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 field controller.
Specific warnings are given at the relevant places in this Guide.
1.3 System design and safety of personnel
The field controller is intended as a component for professional incorporation into
complete equipment or system. If installed incorrectly, the field controller may present a
safety hazard.
The field controller 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 / 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 guide carefully.
The electrical inputs of the field controller must not be relied upon to ensure
safety of personnel. They do not isolate dangerous voltages from the output of
the field controller. The supply must be disconnected by an approved electrical
isolation device before gaining access to the electrical connections.
The field controller is not intended to be used for safety-related functions.
Careful consideration must be given to the function of the field controller 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 field controller 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 field control.
A Warning contains information, which is essential for avoiding a safety hazard.
A Caution contains information, which is necessary for avoiding a risk of damage to
the product or other equipment.
A Note contains information which helps to ensure correct operation of the product.
