1 Safety Information
1.1 Warnings, Cautions and Notes
A Note contains information which helps to ensure correct operation of
the product.
1.2 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 a 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.
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
guide carefully.
The STOP and SECURE DISABLE 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.
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 behaviour 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.
1.4 Environmental limits
Instructions in this 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 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 earth (ground) connections.
This guide contains instruction 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:
98/37/EC: Safety of machinery.
89/336/EEC: Electromagnetic Compatibility.
1.6 Special note on SECURE DISABLE/
ENABLE function in regen operation
In regen operation the enable input of the Regen drive stage has no
safety functions. It only enables the active rectifier operation. It does not
disable any operation of the motoring drive(s) and it does not prevent the
regen stage from producing DC power.
The enable input of the motoring drive stage can be used for safety
functions if required. Consult the
Unidrive SP User Guide
for information
on SECURE DISABLE.
1.7 Adjusting parameters
Some parameters have a profound effect on the operation of the drive.
They must not be altered without careful consideration of the impact on
the controlled system. Measures must be taken to prevent unwanted
changes due to error or tampering.
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.
