5.1 Hazard notes
WARNING
This unit carries dangerous voltage and contains dangerous rotating machine parts (ventilators). This
means that death, serious injury or considerable material damage can occur if the safety and warning
notes are not heeded.
The user is responsible for the assembly of the converter power unit, the motor, the mains filter and
the other components according to applicable safety standards (e.g. EN, 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 incom-
patible with residual current protective devices (EN 50178:1998 section 5.2.11.2).
Variable-speed drives may only be used if their use conforms to valid EN regulations.
DANGER
The DC link carries electrical potential: it is imperative that the provided cover is used.
Special care is needed when touching the drive shaft, directly or indirectly (by hand). This should only
be done in a voltage free state and whilst the drive is stationary.
Safety equipment must under no circumstances be shut down.
