Powerdrive MD Smart Integration Guide
5751 en - 2021.10 / e
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.
(In accordance with the low voltage directive 2014/35/EU)
1 - General information
The integrator is responsible for the selection of the
components for the variable speed drive. All work related to
the installation of the variable speed drive in an enclosure,
such as handling, assembly, installation, cabling and testing
of the finished product, shall be performed by qualified and
authorised personnel. For these basic safety instructions,
qualified personnel shall mean competent persons who
possess the relevant qualifications.
The security instructions described in this document shall be
followed carefully
The variable speed drive produced by the integrator must
be tested to ensure its proper functioning, but it must also be
certified to the standards of the place of use.
Depending on their degree of protection, 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 more information, consult the data sheet for each of the
components described in this document.
2 - Use
Variable speed drives are components designed for
integration in electrical installations or machines.
They shall 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 of variable speed drives can take place only
if the requirements of the Electromagnetic Compatibility
Directive (EMC 2014/30/CE) are met.
The integrator shall ensure the variable speed drives meet
the requirements of the Low Voltage Directive 2014/35/CE.
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 shall be specified on the nameplate of
the variable speed drive and in the documentation provided.
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, cabling
The installation and cabling of variable speed drive
components in an enclosure shall meet the specifications of
the documentation provided.
The variable speed drive components 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.
The variable speed drive components contain parts which
are sensitive to electrostatic stresses and may be easily
damaged if handled incorrectly. Electrical components must
not be exposed to mechanical damage or destruction (may
result in risks to health!).
5 - Electrical connection
When work is performed on variable speed drives which are
powered up, the national accident prevention regulations
must be observed.
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 can be found in the
documentation.
Instructions for an installation which meets the requirements
for electromagnetic compatibility, such as screening, earthing,
presence of filters and correct insertion 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 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 may still be charged.
In view of this, warnings must be fixed to the affected areas of
the variable speed drive’s enclosure.
Permanent magnet motors generate electrical power if they
are rotated, even when the supply to the drive is disconnected.
In this case, the variable speed drive is powered by the motor
terminals. If the load is capable of running the motor, a cut-off
device upstream of the motor must be provided to isolate the
variable speed 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 chapter of this document.
