Control Techniques UD70 Installation Manual page 2

Safety Information
The option card and its associated drive are intended as components for professional
incorporation into complete equipment or systems. 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 mechanical equipment that can cause
injury.
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 and maintenance must be carried out by personnel
who have the necessary training and experience. They must read this safety information
and this Installation Guide carefully.
Careful consideration must be given to the functions of the drive and option card which
might result in a hazard, either through their intended functions, e.g. auto-start, or through
incorrect operation due to a fault or trip, e.g. stop/start, forward/reverse, maximum speed,
loss of a communications link.
In any application where a malfunction of the drive or option card could lead to damage,
loss or injury, a risk analysis must be carried out, and where necessary, further measures
taken to reduce the risk. To ensure mechanical safety, additional safety devices such as
electro-mechanical interlocks may be required. The Drive must not be used in a safety-
critical application without additional high-integrity protection against hazards arising
from a malfunction.
