NORDAC trio SK 300E Frequency inverter
Safety and operating instructions for frequency inverters
(as per: Low voltage guideline 73/23/EEC )
1. General information
During operation, frequency inverters may have, depending
on their protection class, live, bare, moving or rotating parts or
hot surfaces.
Unauthorised removal of covers, improper use, incorrect
installation or operation leads to the risk of serious personal
injury or material damage.
Further information can be found in this documentation.
All transportation, installation and initialisation and
maintenance work must be carried out by qualified personnel
(compliant with IEC 364, CENELEC HD 384, DIN VDE 0100,
IEC 664 or DIN VDE 0110, and national accident prevention
regulations).
For the purposes of these basic safety instructions, qualified
personnel are persons who are familiar with the erection,
installation, commissioning and operation of this product and
who have the relevant qualifications for their work.
2. Intended use
Frequency inverters are components intended for installation
in electrical systems or machines.
When being installed in machines, the drive power converter
cannot be commissioned (i.e. implementation of the proper
use) until it has been ensured that the machine meets the
provisions of the EC directive 89/392/EEC (machine
directive); EN 60204 must also be complied with.
Commissioning (i.e. implementation of the proper use) is only
permitted when the EMC directive (89/336/EEC) is complied
with.
The frequency inverters meet the requirements of the low
voltage directive 73/23/EEC. The harmonised standards in
prEN 50178/DIN VDE 0160, together with EN 60439-1/VDE
0660 Part 500 and EN 60146/VDE 0558 were applied for the
frequency inverter.
Technical data and information for connection conditions can
be found on the rating plate and in the documentation, and
must be complied with.
3. Transport, storage
Information regarding transport, storage and correct handling
must be complied with.
Climatic conditions in line with prEN 50178 must be complied
with.
4. Installation
The installation and cooling of the equipment must be
implemented as per the regulations in the corresponding
documentation.
The frequency inverters must be protected against
impermissible loads. In particular, no components must be
bent and/or the insulation distances changed during transport
and handling. Touching of electronic components and contacts
must be avoided.
Frequency inverters have electrostatically sensitive
components that can be easily damaged by incorrect handling.
Electrical components must not be mechanically damaged or
destroyed (this may cause a health hazard!).
5. Electrical connection
When working on frequency inverters which are connected to
high voltages, the applicable national accident prevention
regulations must be complied with (e.g. VBG 4).
The electrical installation must be implemented as per the
applicable regulations (e.g. cable cross-section, fuses, earth
lead connections). Further information is contained in the
documentation.
Information about EMC-compliant installation – such as
shielding, earthing, location of filters and installation of cables
– can be found in the frequency inverter documentation.
These instructions must also always be observed for drive
frequency inverters CE approval. Compliance with the limit
values specified in the EMC regulations is the responsibility of
the manufacturer of the system or machine.
6. Operation
Systems where frequency inverters are installed must be
equipped, where necessary, with additional monitoring and
protective equipment as per the applicable safety
requirements, e.g. legislation concerning technical equipment,
accident prevention regulations, etc. Modifications to the
frequency inverters using the operating software are
permitted.
After the frequency inverter is disconnected from the power
supply, live equipment components and power connections
should not be touched immediately because of possibly
charged capacitors. Comply with the applicable information
signs located on the frequency inverter.
All covers must be kept closed during operation.
7. Maintenance and repairs
The manufacturer documentation must be complied with.
These safety instructions must be kept in a safe place!
