1 Safety and operating instructions for variable
speed drives
(In accordance with the low voltage directive 73/23/EEC modified by 93/68/EEC).
1.1 Warning
1.2 General
Depending on their degree of protection, the variable speed drives may contain
unprotected live parts, which may be moving or rotating, as well as hot surfaces, during
operation.
Unjustified removal of protection devices, incorrect use, faulty installation or
inappropriate operation could represent a serious risk to personnel and equipment.
For further information, consult the documentation.
All work relating to transportation, installation, commissioning and maintenance must be
performed by experienced, qualified personnel (see IEC 364 or CENELEC HD 384, or
DIN VDE 0100 and national specifications for installation and accident prevention).
In these basic safety instructions, qualified personnel means persons competent to
install, mount, commission and operate the product and possessing the relevant
qualifications.
1.3 Use
Variable speed drives are components designed for integration in installations or
electrical machines.
When integrated in a machine, commissioning must not take place until it has been
verified that the machine conforms with directive 2006/42/EC (Machinery Directive). It is
also necessary to comply with standard EN 60204, which stipulates in particular that
electrical actuators (which include variable speed drives) cannot be considered as
circuit-breaking devices and certainly not as isolating switches.
Commissioning can take place only if the requirements of the Electromagnetic
Compatibility Directive (EMC 2004/108/EC) are met.
The variable speed drives meet the requirements of the Low Voltage Directive 2006/95/
EC. The harmonised standards of the DIN VDE 0160 series in connection with standard
VDE 0660, part 500 and EN 60146/VDE 0558 are also applicable.
The technical characteristics and instructions concerning the connection conditions
specified on the nameplate and in the documentation provided must be observed
without fail.
The SAFE TORQUE OFF (SECURE DISABLE) function meets the requirements of
EN954-1 category 3 for the prevention of unexpected starting of the drive, which allows
it to be used in a safety-related application. The system designer is responsible for
ensuring that the complete system is safe and designed correctly according to
the relevant safety standards.
Throughout the manual, this symbol warns of consequences which may arise from
inappropriate use of the drive, since electrical risks may lead to material or physical
damage as well as constituting a fire hazard.
