OMMISSIONING
DANGER
Due to the nature of electrical equipment, certain parts of this unit carry dangerous voltage during
operation. Serious injury and/or damage to property can result from non-compliance with these safety
notes and warnings.
Only qualified personnel familiar with the safety instructions, and instructions regarding assembly,
maintenance and operation are to work on this unit.
The user is responsible for the assembly of the converter power unit, the motor, the transformer and
the other components according th applicable safety standards (e.g. VDE, DIN) and all other relevant
national or local regulations regarding conductor dimensions and fusing, grounding, circuit breakers,
overcurrent protection etc.
Relatively high leakage to ground occurs in the converter and the motor, i.e. the drive may be
incompatible with residual current protective devices.
In operation, the unit is protected against direct handling in such a way that it is suitable for
installation in enclosed electrical operating areas (DIN VDE 0558 part 1a, sect. 5.4.3.2.1 and
5.4.3.2.2).
Behaviour of the drive in the event of error
Faulty or uncontrolled drive and machine element movement can not be ruled out during initial
commissioning. Hence setial care must be taken.
Prior to activation of the drive, all safety features should be checked through in order to avoid
personal injury. Particular care should be taken with direct or indirect handling of the drive-shaft. This
is only permissible if the shaft is perfectly static and the current converter is in a voltage-free
condition. Freelyy-accessible machine parts (shafts, blowert etc.) must be covered once in operation.
Whilst in use, electrical potential is present in the power circuit, the intermediate circuit and in the
motor windings. Do not touch these components during operation. Only connect measuring equip-
ment when no voltage or current is present.
Handling protection according to §4 Para. 4 VBG 4
Protection against direct handling encompasses all measures against hazards which can result from
the handling of active electrical parts. It is essential that such acitve parts are protected against direct
handling via insulation, type of construction, position and arrangement, or via sturdy reinforcement.
This refers to the fact that covers, seals and procedure should ensure that personnel are not able to
handle parts subjected to voltage.
