SAFETY AND OPERATING INSTRUCTIONS FOR VARIABLE SPEED DRIVES
1 - General information
Depending on their degree of protection, variable speed drives
can contain unprotected live parts, which can 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 manual.
All work relating to transportation, installation, commissioning
and maintenance must be performed by experienced, qualified
personnel (see IEC 364, CENELEC HD 384 or DIN VDE 0100,
as well as 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.
2 - 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 2014/30/EC) are
met.
The variable speed drives meet the requirements of the Low
Voltage Directive 2014/35/EU. The harmonized 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.
3 - Transportation, storage
All instructions concerning transportation, storage and correct
handling must be observed.
The climatic conditions specified in the technical manual must
be observed.
4 - Installation
The installation and cooling of equipment must comply with the
specifications in the manual supplied with the product.
Variable speed drives must be protected against any excessive
stress. In particular, there must be no damage to parts and/
or modification of the clearance between components during
transportation and handling. Avoid touching the electronic
components and contact parts.
Variable speed drives contain parts that are sensitive to
electrostatic stresses and can easily be damaged if handled
incorrectly. Electrical components must not be exposed to
mechanical damage or destruction (risks to health!).
5 - Electrical connection
When work is performed on variable speed drives that are
powered up, the national accident prevention regulations must
be respected.
The electrical installation must comply with the relevant
specifications (for example conductor cross-sections, protection
via fused circuit-breaker, connection of protective conductor).
More detailed information is given in the manual.
Instructions for an installation which meets the requirements
for electromagnetic compatibility, such as screening, earthing,
presence of filters and correct laying of cables and conductors,
are given in the documentation supplied with the variable speed
drives. These instructions must be followed in all cases, even
if the variable speed drive carries the CE mark. Adherence to
the limits given in the EMC legislation is the responsibility of the
manufacturer of the installation or the machine.
6 - Operation
Installations in which variable speed drives are to be integrated
must be fitted with additional protection and monitoring devices
as laid down in the current relevant safety regulations, such
as the law on technical equipment, accident prevention
regulations, etc. Modifications to the variable speed drives
using control software are permitted.
Active parts of the device and the live power connections must
not be touched immediately after the variable speed drive is
powered down, as the capacitors could still be charged. In view
of this, the warnings fixed to the variable speed drives must be
observed.
Permanent magnet motors generate electrical energy while
they are rotating, even when the drive is switched off. In this
case, the drive continues to be powered by the motor terminals.
If the load is capable of turning the motor, a switching device
must be provided upstream of the motor to isolate the drive
during maintenance operations.
During operation, all doors and protective covers must be kept
closed.
7 - Servicing and maintenance
Refer to the manufacturer’s documentation.
See the Maintenance section in this document.
This manual is to be given to the end user.
(In accordance with the low voltage directive 2014/35/EU)
Throughout the manual, this symbol warns of consequences which can arise from inappropriate use of the drive, since
electrical risks can lead to material or physical damage as well as constituting a fire hazard.
