CDA3000 Operation Manual
1.2 Intended use Inverter drives are components that are intended for installation in electri-
cal systems or machines. The inverter may not be commissioned (i.e. it
may not be put to its intended use) until it has been established that the
machine as a unit complies with the provisions of the EC Machinery
Directive (89/392/EEC). EN 60204 (Safety of machines) is to be obser-
ved.
If the frequency inverter is used for special applications (e.g. in areas sub-
ject to explosion hazard), the required standards and regulations
(e.g. EN 50014, “General provisions” and EN 50018 “Flameproof enclos-
ure”) must always be observed.
Repairs may only be carried out by authorized repair workshops.
Unauthorized opening and incorrect intervention could lead to physical
injury or material damage. The warranty provided by LUST would thereby
be rendered void.
1.3 Responsibility Electronic devices are fundamentally not fail-safe. The company setting
up and/or operating the machine or plant is itself responsible for ensuring
that the drive is rendered safe if the device fails.
EN 60204-1/DIN VDE 0113 “Safety of machines”, in the section on “Elec-
trical equipment of machines”, stipulates safety requirements for electrical
controls. The requirements are intended to protect the safety of personnel
and machines and to maintain the function capability of the machine or
plant, and must be observed.
The function of an emergency off system does not necessarily have to cut
the power supply to the drive. To protect against danger, it may be more
beneficial to maintain individual drives in operation or to initiate specific
safety sequences. Execution of the emergency off measure is assessed
by means of a risk analysis of the machine or plant, including the electri-
cal equipment to EN 1050, and is determined with selection of the circuit
category in accordance with prEN 954 “Safety of machines - Safety-rela-
ted parts of controls”.
The CDA3000 conforms to the Low Voltage Directive
(73/23/EEC).
EMC The following generic standards are complied with in
application of the installation instructions:
• EN 50081-1 and EN 50081-2 (line-borne and radiated
interference emission)
• IEC 1000-4-2 to 5 / EN61000-4-2 to 5 (Interference
immunity of the inverter module)
