Safety and application notes

for controllers

(according to: Low-VoltageDirective 73/23/EEC)

1. General

During operation, drivecontrollersmay have, according to their typeof protec-

tion, live, bare, insomecases also movable or rotating partsas wellas hot sur-

faces.

Non-authorized removalof the required cover, inappropriate use, incorrect in-

stallation or operation, creates the risk of severe personal injury or damage to

materialassets.

Further information can be obtained from the documentation.

Alloperationsconcerningtransport,installation,andcommissioningaswellas

maintenance must be carried out by qualified, skilled personnel (IEC 364 and

CENELECHD384orDINVDE0100andIECreport664orDINVDE0110and

national regulations for theprevention of accidents must be observed).

Qualified skilled personnel according to this basic safety information are per-

sons who are familiar with theerection, assembly, commissioning, and opera-

tionoftheproduct and whohavethequalifications necessaryfortheiroccupa-

tion.

2. Application as directed

Drive controllersarecomponentswhich aredesigned for installation inelectri-

cal systems or machinery.

When installing in machines, commissioning of the drive controllers (i.e. the

starting of operation asdirected)isprohibited until it isproventhat themachine

corresponds to the regulations of theEC Directive 89/392/EWG(Machinery

Directive); EN 60204 must be observed.

Commissioning (i.e. starting of operation as directed) is only allowed when

there is compliance with the EMC Directive(89/336/EWG).

The drive controllers meet the requirements of the Low Voltage Directive

73/23/EWG. The harmonized standards of the prEN 50178/ DIN VDE0160

series togetherwith EN 60439-1/DIN VDE0660 part 500 and EN 60146/DIN

VDE0558 areapplicableto drivecontrollers.

The technical data and information on theconnection conditions must be ob-

tained fromthenameplateand the documentation and must beobserved inall

cases.

3. Transport, storage

Notesontransport, storage and appropriatehandling must beobserved.

Climatic conditionsmust beobserved according to prEN 50178.

4. Erection

Thedevices must erected and cooled according to the regulations of thecor-

responding documentation.

Thedrivecontrollersmustbeprotected frominappropriateloads. Particularly

during transport and handling, components must not bebent and/orisolating

distances must not bechanged. Touching ofelectronic componentsand con-

tactsmust beavoided.

Drive controllers contain electrostatically sensitive components which can ea-

silybedamaged byinappropriatehandling.Electrical components must not be

damaged or destroyed mechanically (health risks are possible!).

5. Electrical connection

When working on livedrivecontrollersthe valid nationalregulationsforthepre-

vention of accidents (e.g. VBG 4)must be observed.

Theelectricalinstallationmust becarried out according to theappropriatere-

gulations (e.g. cablecross-sections, fuses, PEconnection). More detailed in-

formation is included in the documentation.

Notes concerning theinstallation incompliance withEMC - such asscreening,

grounding, arrangement of filters and laying ofcables- areincluded inthedo-

cumentation of the drive controllers.These notes must also be observed in all

cases for drive controllers withtheCEmark. The compliancewith therequired

limit values demanded by the EMC legislation is inthe responsibilityof the ma-

nufacturer of the system or machine.

6. Operation

Systems where drive controllers are installed must be equipped, if necessary,

with additionalmonitoring and protectivedevicesaccording to thevalid safety

regulations, e.g. law on technical tools, regulationsfor thepreventionof acci-

dents,etc.Modificationsofthedrivecontrollersbytheoperatingsoftwareare

allowed.

After disconnecting the drive controllers from the supply voltage, live parts of

the controller and power connections must not be touched immediately, be-

causeofpossiblychargedcapacitors.Forthis,observethecorrespondingla-

bels on the drive controllers.

During operation, all covers and doors must be closed.

7.Maintenance and servicing

The manufacturer’s documentation must be observed.

This safety information must be preserved!

The product-specific safety and application notes in these operating instruc-

tions must also beobserved!
