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.
Careful consideration must be given to the function of the drive which might result in a
hazard, either through its 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 within the supplied data and information within the Commander SK Product
Data Guide regarding transport, storage, installation and the use of the drive must be
complied with, including the specified environmental limits. Drives must not be
subjected to excessive physical force.
